3 Return to Table of Contents INTRODUCTION Introduced in November 2006, the new and improved version 2.0 Casey MSV10 HVAC Monitoring System detects problems on virtually all forced air heating and cooling systems including: Cooling- Conventional single stage, single speed compressors. Heating- Single or 2 stage Gas Single stage Electric. Heat Pump- HP Only HP with Electric Back Up - Dual-Fuel systems This manual covers most installation & operating conditions. However, should an unusual problem come up, special instructions that can be found in Appendix N: Troubleshooting Tips If you experience a problem not covered in this manual, please feel free to call toll free for technical assistance USING THE CASEY MSV10 HVAC MONITORING SYSTEM Return to Table of Contents PART1: AN OVERVIEW OF THE MSV10 What is it? The Casey MSV10 is a small, specialized computer with air sensors designed to monitor the operating efficiency of heating and air conditioning systems. The Tech Pad is a necessary Casey tool used for viewing and inputting heating & cooling system information. Its keypad interacts with the menu instructions displayed on its screen for easy Casey set up. Each type of HVAC system (Gas, Electric or Heat Pump and Air Conditioning) set up & calibration data is stored in the Tech Pad. When plugged into the MSV10, the Tech Pad can program the to work with any type of system. Air sensors are placed in the return & supply air ductwork to continuously report temperature & relative humidity readings to the computer unit. An optional outdoor temperature sensor can be installed if outside air temperature readings are desired (primarily used on heat pump systems, but may also be used with conventional systems). The MSV10 System: Return & Supply Air Sensors, Outdoor Temp Sensor, Computer Unit and Tech Pad 1

4 What improvements do the MSV10 (V2.0) have from previous versions? The MSV10 (V2.0) modem, processor, thermistors and air sensors are improved; the F2 terminal now works with normally opened or closed sensors; and the supply and return air sensors connect to the terminal block for improved reliability. In general the MSV10 operates essentially like as earlier versions but has enhanced circuitry, components and operating software How does it work? The MSV10 s computer compares the difference in the return & supply air sensor readings to what it calculates the temperature split should be (it has a built in psychrometric table with formulas). For gas heat systems, the MSV10 s calculated temperature split (also referred to as Delta T or D/T ) is factory set at 55º. Above and below this 55º benchmark D/T is 20º tolerance range. The tolerance range allows the gas system s temperature rise to be as high as 75º (55º + 20º) or a low as 35º (55º - 20º) before the MSV10 sends an alert report. Please see Figure # 1: Gas Heat (below): Figure #1 GAS HEAT Supply Air Difference is Temp Rise Return Air Above 75º - High D/T Alert Report Sent + 20º Tolerance Range - 20º Tolerance Range Below 35º - Low D/T Alert Report Sent 75º Max D/T 55º MSV10 Calculated D/T 35º Min D/T For cooling systems, the MSV10 s calculated D/T will vary depending on the relative humidity at the return air sensor. At 50% relative humidity, the MSV10 calculates an 18º D/T. As humidity increases, the MSV10 calculates a lower D/T and, as humidity decreases, it calculates a higher D/T. The tolerance range for cooling is 6º. Therefore, at 50% relative humidity, the MSV10 sends a report when the temperature fall is less than 12º (18º - 6º) or higher than 24º (18º + 6º).. Please see Figure # 2: Cooling (below): Figure #2 COOLING Above Dotted Line-High D/T Alert Report Sent 24º Max 50% RH Supply Air + 6º Tolerance Range MSV10 Calculated D/T 18º at 50% RH Difference is Temp Fall Note: The Lower the Humidity, the Higher the Difference - - 6º Tolerance Range 35º Min 50% R/H Below Dotted Line-Low D/T Alert Report Sent Return Air 0% 50% 100% 2

5 At the end of Part 4: Standard Calibration Percentage & Relative Set Up Values Humidity is a chart that shows calculated D/Ts and Tolerance Ranges by each type of system. Regardless the types of system, all problems are detected by the MSV10 constantly comparing the difference in return & supply air sensor readings to its own calculated D/T (plus or minus the tolerance range). When a problem is found, the MSV10 s built in modem calls a toll free 800 number to SmartWay s central station. Upon receiving the data, which includes a unique number assigned to each contractor, the central station immediately transmits an alert report to that contractor. If the customer isn t using their phone while the MSV10 dials out, the alert report is received in about 3 to 4 minutes from the problem detection. MSV10 Standard Features & Capabilities: Constant real time monitoring of the system s operation Works on most types of heating & cooling systems Sends alert report when system calibration settings exceeded Alert report includes total running hours to date by mode (i.e. heating, cooling & fan) After one hour of electrical outage a report is sent using power from 9V back-up battery Sends diagnostic information of system fault condition, set up values, actual & calculated D/T (temperature split), HVAC system information and troubleshooting tips Sends an alert report when the air temperature at the return air sensor exceeds the high or low temperature settings (even when the HVAC system is off) Note: The MSV10 requires input from the thermostat to determine system performance. If the thermostat is broken, the MSV10 cannot send a poor performance alert report. However, as a safety net, whenever the minimum & maximum temperature settings are exceeded, an alert report will always be send, even if the thermostat is not working. Sends a monthly check in report to confirm the MSV10 is operating correctly. Alert reports are transmitted from the MSV10 via a toll free 800-number to SmartWay s central monitoring station, which are immediately forwarded to the contractor by fax, and internet posting (on a private web page at Tech Pad downloads the MSV10 computer with standard calibration settings for all types of heating & cooling systems (Gas, Electric & Heat Pump) Tech Pad downloads the MSV10 computer with standard set up values (heat & cool tolerance, min & max temperatures & system delay time) Tech Pad can be used to manually change default set up values and heat calibration settings ( quick heat calibration). Option to have the heating & cooling system calculate its own best calibration settings (i.e. custom calibration) Uses existing customer phone line to send alert reports. Won t interrupt the phone line when being used by customer. Automatically detects when the line becomes available and then sends the alert report. Optional Features: Outdoor Air Temperature Sensor: sends outside air temperature when connected Water Alert Float Switch: detects water accumulation in drain pan, etc. Customer Alert Switch (allows customer to manually initiate an alert report) 3

6 Overview Summary The MSV10 computer unit is the brain that interprets information received from the thermostat, the return and supply air sensors and the Tech Pad. The computer unit is mounted near the HVAC system and is wired to the return and supply air sensors, telephone line and thermostat. The return and supply air sensors are installed in the ductwork to monitor temperature, airflow, and relative humidity. An optional outdoor air temperature sensor can be used to monitor outside air temperature (primarily used with heat pump systems). The Tech Pad plugs into the middle jack (RJ-45) located at lower edge of case for entering set up & calibration information and viewing system performance. Every MSV10 is calibrated to the best operating range for the type of HVAC system it s monitoring. Calibration is done by any of the following three ways: 1. Standard Calibration is the default calibration setting from the factory that s acceptable for most systems. If the standard calibration setting is changed, it can be restored with the Tech Pad 2. Custom Calibration is obtained by running a HVAC system for a few minutes and having the MSV10 detect the best calibration setting for that specific system. 3. Quick Heat Calibration is a quick way to manually increase or decrease the heat calibration setting with the Tech Pad. Only heat D/T (not cooling) can be adjusted with Quick Heat Calibration. The built in modem connects to the customer s existing phone line and dials a toll free 800 to send an alert report when a fault is detected. PART 2: GETTING FAMILIAR WITH THE MSV10 A quick way to learn about the MSV10 is to set up one at a workbench. Just connect it to a 24V transformer and thermostat and follow the simple steps below. You ll soon see how easy the MSV10 is to use. Steps for Getting Familiar with the MSV10 and Tech Pad 1. Connect the 24V transformer & thermostat to the monitor (see the wiring diagram on page 9 or in Appendix U: Wiring the MSV10 to Your System ) 2. Connect the 2 wires from the metallic silver Supply Air Sensors to terminals # 1 & 2, labeled WHT WHT on the sensor terminal block. The sensor terminal block is the terminal block #2 (middle) located on right side of the circuit board (under the flip open transparent door). 4

7 3. Connect the 4 color coded wires from the black plastic Return Air Sensor to terminals # 3,4,5 & 6 labeled RED, BLK, WHT, GRN on the sensor terminal block (terminal block # 2). 4. Make sure the Power Slide Switch (located in the lower right hand corner of the circuit board) is in the ON position. 5. Plug in the Tech Pad into the middle RJ45 jack on the lower edge of the case. The two jacks on each side of the Tech Pad jack are RJ11 jacks for the phone and Customer Alert switch. 6. The Tech Pad will boot up and its screen will display the Software Versions for your Tech Pad and MSV10 (Note: software version numbers might change causing yours to be different). ESM-20 V 4.09 ESM-10 V 2.91 ESM- 20 refers to the Tech Pad ESM-10 refers to the MSV10 7. The Tech Pad displays the Contractor Code. If this is your SmartWay assigned contractor code, press YES. If this is not your contractor code, press NO and enter your contractor code. CONT: 1234 YES OR NO CONTRACTOR CODE Note: You should have your assigned contractor code from your first MSV10 order. If you don t know your contractor number, please call SmartWay toll free at The Tech Pad displays the Customer Code. You can enter any number desired, up eight digits, to identify your customer. Many contractor use their customer s seven digit phone number and, if more than one system, use the eighth digit to identify each. CUST # YES OR NO Press the YES key on the Tech Pad to accept this. Always make sure to enter a unique number for each customer (and each customer s system if more than one). 8. The Tech Pad displays: STATUS OK 5

8 This is the starting point for everything with the MSV10 monitoring system. Note: When the MSV10 has actually detected a fault condition, instead of "STATUS: OK", the display will show the actual fault (e.g. "F2 FAULT", TEMP MAX=121 etc.). 9. Turn the thermostat Fan switch to the "ON" position and press the "D/T" key. The Tech Pad displays: THERMOSTAT IS SET TO FAN 10. Now turn the fan switch to "AUTO" and the screen will display: THERMOSTAT IS SET TO IDLE 11. Turn the thermostat to "HEAT" & raise the temperature at least 10º above the room s temperature. The Tech Pad displays something like the following: HEAT D/T 01 HEAT CALIB D/T 55 Note: It will take the MSV10 computer approximately 35 seconds to calculate the Heat Calibration D/T before it appears on the screen. The first line HEAT D/T is the actual temperature split between the return & supply air sensor. Because the MSV10 is not installed, there will be little if any temperature split. The second line HEAT CALIB is what the MSV10 calculates what the D/T should be. Note: If the HEAT CALIB number stays at "0" for more than 60 seconds, you need to calibrate the system for heat (see Appendix E: Tech Pad CAL +2 Keys ) 12. Now turn the thermostat to COOL & lower the temperature at least 10º below the room s temperature. The display shows something like the following: COOL D/T 01 COOL CALIB D/T 20 Note: When changing from Heat to Cool, it will take approximately 35 seconds before the Cool Calibration D/T is calculated and appears on the screen. This will not happen when the MSV10 is installed in an operating system as changing from Heat to Cool (and vice versa) doesn t normally occur. The first line COOL D/T is the actual temperature split between the return & supply air sensor. Because the MSV10 is not installed, there will be little if any temperature split. The second line COOL CALIB is what the MSV10 computer calculates what the D/T should be. Note: If the COOL CALIB stays at "0" for more than 60 seconds you need to calibrate the system for cool (see Appendix E: Tech Pad INITIALIZE/RESTORE + 2 Keys ). 13. Now go ahead and explore the MSV10 on your own! 6

10 MSV10 INSTALLATION STEPS 1. Turn off the power to the HVAC system 2. Locate the MSV10 between the return air and supply air ducts so the eight (8) foot Supply and Return Air Sensor cables will reach it. It can be mounted on the wall or the return air duct. 3. After selecting the mounting location, drive a sheet metal screw (not supplied), leaving the head of the screw 1/8 in from the wall or duct. Remove the setscrew holding the front cover and swing open. Hook the MSV10 onto the screw and mark the location for the second screw. While holding in place, drive the second mounting screw where marked. Installation Diagram-Vertical System Installation Diagram-Horizontal System 4. Drill a 1-1/8" hole in the return air duct for installing the black plastic Return Air sensor pod. Mount & secure with sheet metal screws (not included) so the sensor it can t be exposed to water from a frozen evaporator coil or overflow drip. 5. Drill a ¼ hole in the supply air duct for installing the silver metallic Supply Air sensor. Mount & secure with sheet metal screws (not included) so the sensor is at least 18" downstream from the furnace and/or the evaporator coil. 6. Connect the 2 wires from the silver metallic Supply Air Sensor to terminals # 1 & 2 labeled WHT WHT on the sensor terminal block. The Sensor terminal block is the middle (or #2) terminal block located on right side of the circuit board (under flip open transparent door). 7. Connect the 4 color coded wires from the black plastic Return Air Sensor to terminals # 3,4,5 & 6 labeled RED, BLK, WHT, GRN on the sensor terminal block. Note: Make sure the power is off to the HVAC system before going further! 8

11 8. Loosen the terminal screws on the MSV10. Connect the system using 5-conductor thermostat wire (use 6-conductor wire if Heat Pump) between the MSV10 terminal strip and the Furnace/Air Handling Unit terminal strip as shown on the wiring diagrams below. Note: On Fail Safe Cool Heat Pump Systems connect the B wire to the MSV10 Y/O terminal and move the #2 DIP Switch (located on the upper left hand side of the circuit board) to the right or ON position. If you have a digital or programmable thermostat in which you must program the O terminal to be a B terminal, please see the diagram in Appendix U: Wiring the MSV10 To Your System. Please feel free to call SmartWay toll free (866) for additional assistance. 9

12 General Wiring Diagram MSV10 COMPUTER Close Up of MSV10 (V2.0) Terminal Wiring to Thermostat MSV10 (V2.0) Circuit Board Diagram Optional Outdoor Temperature Sensor: (Used with heat pump systems to report outside air 10

13 temperature): Mount sensor in a protected outside location. Connect the two wires from the outdoor sensor to the External Temperature Sensor Terminal (see Terminal Block #4 located at top right hand corner as shown on previous page MSV10 Circuit Board diagram). Note: The MSV10 has a factory default outside air temperature setting of 46º F (Press the F4 key on the Tech Pad to see outside air temperature readings). This constant setting (46º F) can be used instead of an external air sensor for heat pump systems located in moderate climates (see the Heat Pump Delta T Chart in Appendix T: Useful Charts & Tables ). However, when maximum accuracy is desired, install the outdoor temperature sensor to override the 46º F default setting 9. Check wiring connections & set the thermostat to FAN. 10. Turn on the power to the HVAC system and make sure the MSV10 power switch is in the ON position. Look at the RED and GREEN LED Alarm Lights labeled CR3 and CR4 located at top right hand corner (just left of Terminal Block 4). If operating correctly the Green LED (CR4) lights up and the RED LED (labeled CR3) briefly flashes but doesn t light up. Note: Always make sure the MSV10 power switch is ON and you have 24V power. If the Tech Pad displays SYSTEM POWER OFF you re running only off the battery. If so, double check the 24V common & ground connection to the MSV10 terminal strip (i.e. make sure there s 24V between R & C on the terminal strip). If not operating correctly the GREEN LED will not light up (regardless whether the GREEN or RED LEDs briefly flash). It s likely that the wiring is shorted to an air sensor. To determine if this is the problem, turn off the power, disconnect the sensor wiring and then turn the power back on. If it powers up correctly repair or replace the bad sensor wiring. Note: If the wiring is good, but the GREEN LED still doesn t light up, disconnect all terminal wiring except 24V to the unit and see if powers up. If it does, carefully rewire & check again. If it doesn t, see Appendix N: Troubleshooting Tips for other corrective suggestions and/or contact SmartWay for technical assistance. 11. Plug in the Tech Pad The Tech Pad displays the current software version of the Tech Pad (identified as ESM 20 ) and the MSV10 unit (identified as ESM 10 ). The following is an example; your software versions may differ. ESM 20 VERS 4.09 ESM 10 VERS 2.91 Note: If the Tech Pad s display is hard to read, press the LIGHT button on the Tech Pad (lowest row - middle key). 12. The Tech Pad displays the Contractor Code. If this is your contractor code, press YES. If this is not your contractor code, press NO and enter your Contractor Code. CONT: 1234 YES OR NO 11

The display should always show 0. Press the YES key. ACCESS 0 YES OR NO 15. Tech Pad then displays STATUS: OK STATUS: OK Tech Pad with Status: OK screen 16. Run the FAN without heating or cooling for at least five (5) minutes Press the S/A key to see the Supply Air Temperature (this is an example): SUPPLY AIR TEMP = 72 Press the R/A key to see the Return Air Temperature (this is an example): RETURN AIR TEMP = 73 IMPORTANT NOTE: If the temperatures of the Return and Supply Air Sensors are off more than 1º F from each other you can adjust the Supply Sensor to equal the Return Sensor reading. To do so, press the CAL/6 key and then the 2 key ( 2-TEMP ) and then press the YES key ( ADJ. TEMPERATURE SENSORS YES ). At the next screen ( RETURN TEMP = XX UP/DN OR ENTER ) check that that Return Air Sensor temperature looks OK. Remember that temperature and then press the ENTER key. At the next screen ( SUPPLY TEMP = XX UP/DN OR ENTER ), press the UP or DN key until the Supply Air temperature equals the Return Air temperature. You do not have to adjust the sensors to your own thermometer readings. Just make sure the Supply Air equals (=) the Return Air temperature reading. 12

15 Press the R/H key to see the Relative Humidity (at the Return Air) (this is an example): RETURN AIR R/H = 52% Press the ENTER key to return to Status OK screen STATUS OK 17. If you have a gas heat system, it is already calibrated. If so, press ENTER and skip to step 22. If you need to change the type of heating system to Electric Heat or Heat Pump (or you just want restore the MSV10 to the original factory settings) continue the following steps. Press the RESTORE/INITIALIZE key and then press the 2 key (2 RESTORE). 1 INTIALIZE 2 RESTORE Note: Do not press 1 INITIALIZE (for more information about the 1 INITIALIZE key, please see Appendix D: Tech Pad Initialize/Restore + 1 Keys (1 Initialize) 18. The next screen requests the type of heating system. Select your type of system by pressing 1 for Gas, 2 for Electric or 3 for Heat Pump HEAT: 1 GAS 2 ELECT 3 HP 19. The screen then changes to Calculating (Gas or Electric or HP) Set Up while the MSV10is calculating. The following example shows Calculating Electric Set Up, but it could be Calculating Electric Set Up or Calculating HP Set Up. CALCULATING ELECT SET UP 20. The next screen requests you select the (Air) Sensor Type. Press the 3 key (MSV) for the MSV10. Do not select 1 ESM. ESM is used only for early version monitors (i.e. blue metal case MS10 monitors).

16 22. After resetting, the screen will again show the software version and then repeat the Customer # confirmation screens (see previous step # s 11) and finish with Status OK screen. Note: If the display asks you for Contractor and Access Code numbers, just enter your company s Contractor Code number and enter 0 (zero) for the Access Code number STATUS: OK 23. Start the HVAC system in the appropriate mode (Cool or Heat). Press the D/T key (upper right hand key on Tech Pad) to view the temperature difference between the return & supply air as it rises (in heat) or falls (in cool). HEAT D/T 40 CALC D/T 55 Temperature D/T reading increases until HEAT stabilized Note: The Calculated D/T # takes up to 35 seconds for the MSV10 computer to calculate & display it on the screen. Note: If Gas Heat and the HEAT D/T rises above 80º F, we recommend that you should either: 1) increase your blower one speed higher or 2) increase your CALC D/T by using the Quick Heat Calibration (i.e. press the # CAL/6 key, then the # 4 key and then press the UP key until the desired D/T is reached. See Appendix H: Tech Pad Keys (4 D/T) for more information). 24. Connect a phone line from the RJ11 phone jack located at the lower left side of the circuit board to any convenient phone jack. If a phone jack is not available, please see Appendix M: Wiring a Telephone Connection for help in connecting a phone line. 25. Manually send your first alert report to verify the phone line is correctly connected and that the MSV10 is communicating with SmartWay s central station. To manually send a report: a. Make sure the customer s phone is not in use and then b. Press the CLEAR button for approximately ten (10) seconds until the RED LED light shines steady (along with the GREEN LED). (The CLEAR button is a small white push button located above the ON/OFF Power Slide Switch between the white header posts on circuit board) Note: If after about 20 seconds the RED LED starts blinking: The house s phone is in use or The Contractor Code # is incorrectly programmed to 0 (zero) or The phone line is faulty. For more correction tips please see Appendix N: Troubleshooting Tips (Phone & Fax Troubleshooting). c. The RED and GREEN LED lights will shine steady for about seconds out while the modem dials out. d. The RED LED lights will briefly flash when monitor connects to central station and then continue to shine steady while transmitting data. e. The RED LED will go out and the GREEN LED will continue to shine steady when the data has been successfully transmitted to the central station. 14

17 Note: If the RED LED starts blinking: the MSV10 did not connect to the central station (usually due to busy external phone lines) and the report was not transmitted. Try once more to manually send a report by again pressing the CLEAR button for approximately 10 seconds until both the RED and GREEN LEDs shine steady (while the modem again dials out). 26. Unplug the Tech Pad and fasten the cover over the MSV10 circuit board. The installation is now completed. Return to Table of Contents PART 4: STANDARD CALIBRATION & SET UP VALUES Standard Calibration The best possible temperature difference between the return & supply air sensors is the Calibrated D/T or Calculated D/T ( D/T stands for Delta T or Difference in Temperature ). The Calculated D/T is the benchmark that the MSV10 uses to determine whether a system s correctly operating. Standard Calibration is an industry average D/T which most the heating or cooling systems should operate. Standard Calibration settings for 1) Gas heat w/ac, 2) Electric heat w/ac or 3) Heat Pump (Electric Back Up or Dual Fuel) are stored in the Tech Pad for easy download to the MSV10 computer. The default settings of each are shown on the chart on the next page. Standard Calibrations work very well on most heating & cooling systems. SmartWay recommends adjusting the Standard Calibration settings only when fine tuning is required for special or unusual systems. Reasons to Use Standard Calibration: Quicker Installation: With minimum training tune up and/or installation technicians can install the MSV10. Less Installation Calls: Standard calibration eliminates having to return for Custom Calibrating of Heat in the winter or Cool in the summer Less Time on the Job: increases job profitability. Note: Programming the Standard Calibration of a MSV10 from one type of heat to another, is easily done by pressing the RESTORE key. ( INIATILIZE need only be used the first time you program a MSV10) To program a different type of heat s Standard Calibration follow the steps below: How to Program Standard Calibration Settings 1. Press the INIATILIZE/RESTORE key 2. Press the 2 key to select RESTORE 3. Select the type of HEAT: Press the 1 key for GAS or Press the 2 key for ELECT or Press the 3 key for HP To again change to another type of heat, follow this same procedure over again i.e. Press the CAL key, Press the 2 RESTORE key, and then Press the 1, 2 or 3 key.) 15

18 Changing Standard Calibration Settings It is sometimes desirable to adjust the Standard Calibrated D/T. For further explanation of why this might be necessary and how to make Calibration changes, please see Appendix H: Tech Pad Keys (4 DT) for Quick Heat Calibration or Appendix F: Tech Pad Keys (1 CALIB) for Custom Calibration. Standard Set Up Values MSV10 s are shipped from the factory with Standard Set Up values (shown in chart on next page) that are usually right for most systems. Tolerance Range: The number of degrees the temperature can vary (above or below) the Calibrated D/T before an alert report is sent. Trip Range: The actual minimum & maximum D/Ts permitted. When the system's actual D/T goes above the maximum D/T (or below the minimum D/T) an alert report is sent. Time Delay Settings: The time a fault must exist before an alert report is sent. Should usually be at least the time it takes the HVAC system to stabilize. Temperature Alarm Settings: The minimum and maximum air temperature permitted at the return air sensor. If either is exceeded, an alert report is sent. Changing Standard Set Up Values It is sometimes desirable to change the Standard Set Up Values. Please see Appendix C: Tech Pad Set Up Key for why this might be necessary and how to make changes.

A unique Contractor Code # was assigned to your company when you first registered with SmartWay (for more information on registering, please see Appendix W: Contacting SmartWay for Assistance ). The Access Code # is always zero ( 0 ) unless you are otherwise advised SmartWay s central monitoring station uses the Contractor and Access Code numbers to send alert reports to the correct contractor. CONTRACTOR Code # (up to four digits) Note: Once a Tech Pad has been used to INIATILIZE an MSV10, it will remember your Contractor # and automatically download it into other MSV10 units. ACCESS Code # must be 0 (zero) Note: Tech Pads automatically download 0 (zero) as the correct Access Code # into MSV10 units. If your Tech Pad has any other Access Code numbers, please change them to 0 (zero) unless otherwise advised by SmartWay. Important Note: Your Contractor & Access ID Codes Are Important Because: You won t receive alert reports unless the above numbers are correctly entered. If you do not have or know your assigned Contact and Access Code numbers, please see Appendix W: Contacting SmartWay for Assistance. The MSV10 (V 2.0) s modem won t dial out if the Contractor Code # is 0 (zero). This is a precaution against not entering a Contactor number (the default number is zero). CUSTOMER Code # (this can be up to 8 numbers) The Customer s ID number tells you which customer has sent an alert report. You can use any number desired up to eight (8) digits. This could be the customer s account number or their 7-digit phone number - with the last (8 th ) digit designating which monitor is reporting (if more than one MSV10 is installed at customer s house). To change the ID numbers: 1. Press the ID Key on the Tech Pad 2. The Tech Pad displays a Contractor # CONT: XXXX OKAY? YES OR NO 3.

YES OR NO Return to Table of Contents APPENDIX J: TECH PAD FAULT CONDITIONS When a fault is detected, the MSV10 checks and re-checks its results for the SYSTEM DELAY TIME before sending an alert report. This is to eliminate nuisance reporting. The default factory System Delay Time is 20 minutes except heat pump which is 30 minutes (all delay time settings are adjustable). When the MSV10 is in fault mode the circuit board s RED LED (located at top right corner) light will flash. To see the fault condition, plug in the Tech Pad and the fault will appear immediately after the software screen is displayed. Types of Fault Conditions (with examples of Tech Pad display): 1. Delta "T" fault (example): COOL DT = 22 CALC DT= 15 Note: When in a fault condition, the Tech Pad will display the COOL D/T (or HEAT D/T) reading (in this example 22 ) offset one space to the right. Note: in this example the actual COOL D/ T of 22º is 7º higher than the calculated CALC D/T of 15º. A 7º split is 1º more than the permitted 6º cool tolerance range. 2. Maximum temperature fault (example): MAX TEMP = Minimum temperature fault (example): MIN TEMP = 39 32

35 4. Normally open or closed auxiliary switch fault (F1 or F2 faults) (example): F1 SWITCH = CLOSED 5. Power failure alarm POWER IS OUT Clearing Fault Conditions: Manually Clearing Fault Condition You can clear a fault condition by briefly pressing the CLEAR button (the small white push button located above the ON/OFF Power Slide Switch on the MSV10 circuit board). After clearing the fault, press the Enter key on the Tech Pad and the display will then read STATUS: OK. Note: Because holding the CLEAR button down (for approximately 7 or more seconds) will manually initiate a report, make sure to only briefly press the CLEAR button to clear a fault condition. Automatic Clearing of Fault Condition The MSV10 automatically clears a fault after 18 hours (if it has not been previously manually cleared). After clearing the fault the MSV10 resets itself to an active monitoring state. However, if the fault condition still exists, the MSV1 0will trip again. Important Note: To prevent a run away fault condition, the MSV10 auto resets itself only three (3) times from the same continuous fault condition. It will then lock out sending any more alert reports until manually cleared or the monthly check in (which ever comes first). Return to Table of Contents APPENDIX K: CIRCUIT BOARD RED & GREEN LED INDICATOR LIGHTS The following will describe what the MSV10 Circuit board LED RED & GREEN indicator lights mean: GREEN LED Shines Brightly and Constantly: indicates the MSV10 is operating correctly and not in fault condition Blinks Continuously: indicates the MSV10 is in a fault condition. Not Illuminated or Dim (not shining brightly): indicates the MSV10 is running off the battery (no 24V); or there maybe a short in the sensor cables or incorrectly wired; or a faulty circuit board. 33

36 RED LED Shines Brightly and Constantly: indicates the MSV10 is connecting to SmartWay s central station computer. Blinks Continuously: indicates the MSV10 failed to connect with SmartWay s central station computer. Return to Table of Contents APPENDIX L: WIRING TELEPHONE CONNECTIONS If a modular phone jack is not available, you may need to wire the telephone connections directly into a junction box. The MSV10 uses the two center wires of the 4-wire cable. These two wires are red and green. When wiring to a junction box always connect red-to-red and green-to-green. The MSV10 does not use the other two wires, and it is not necessary to wire them up. Note: Telephone company personnel advise that some newer, multi-line installations are paired wires consisting of a blue wire with a thin white stripe or tracer, and a white wire with a thin blue line or tracer is used in place of the red and green wire pair. MSV10 Computer Splicing into the phone junction ( biscuit ) box Wiring directly the main phone box ( biscuit ) box For further information you may wish to refer to specialized telephone installation manuals such as Radio Shack's Installing Telephones publication # Important Note Regarding Use with Tone Phone Connections: MSV10 monitors only work on Pulse phone systems and will not work on Tone phone systems at this time. Most areas have Pulse phones. To check if Pulse is available, set the Pulse/Tone switch on any phone to Pulse and see if you can dial out. "Wireless Phone Jack Systems" If you have a problem in getting to a convenient phone line, you might consider using a Wireless Phone Jack System to make a phone connection. Wireless phone jack systems require the house s wiring have an electrical current to operate. A general electrical outage will disable the wireless phone jack and you will be unable to receive MSV10 power outage alert reports. 34

37 Modular Privacy Adaptor prevents fax machines, answering machines and computer from picking up or interfering with the MSV10 dial out. In some rare cases, another device (fax, computer, and answering machine) will interfere with the MSV10 operation by seizing the phone line when the MSV10 is trying to dial out. Attaching a modular privacy adaptor to the other device(s) phone line can almost always solve these problems. One such modular privacy adaptor, the SER2A model is available at Mike Sandman Enterprises, Inc. at or phone # (cost at time of this manual was $6.99 each). If you install a modular privacy adaptor, please explain its operation to the homeowner. Important Note: Do not attach a modular privacy adaptor to the MSV10 (V 2.0) s phone line, as it will interfere with it's built in tone detector protector circuit. (See Appendix I: Tech Pad TEL/9 Key ). The protector circuit on all MSV10 units works in a different way from other company modular privacy adaptors. If the homeowner is using the phone, the MSV10 will not dial out or cause any interference with the homeowner s call. Instead the MSV10 will repeatedly try approximately every two minutes to detect a free line. Once the line is open, the report is immediately transmitted. In the unlikely event the homeowner should pick up the phone while the MSV10 is dialing, unlike the modular privacy adaptor, the line will not go dead. Instead the homeowner will hear the unit dialing and when the transmission is completed (takes less than one minute), the dial tone will be restored.

Troubleshooting Tips for Setting up Special Applications Using (RCA) Wireless Phone Jack Systems Wireless phone jacks can be used to connect the MSV10 to a remote phone jack. These systems come with a base unit, extension unit and 6 ft. of phone cord (#RC 926). Please note a number of rules that must be observed when using wireless phone jack systems: 1. Do not use with a power strip or surge protector. 2. Use a Modular Privacy Adaptor between the monitor and the wireless extension unit. This will prevent the monitor from interrupting customer phone conversations. 3. Only use the wireless phone jack system for phones. 4. Do not use the wireless phone jack system for modems. When wireless phone jack systems are used, power outage reports cannot be transmitted. Time Delay Relays If the TDR is set longer than 5 minutes you may want to increase your SYSTEM DELAY TIME so that your system has time to stabilize. 38

41 Two Speed Cooling Units Most Two Speed units will maintain the same D/T on High or Low speed. This is because the evaporator fan motor changes speed with the 1 st and 2 nd speed. The 2 or 3 degrees difference should not affect the efficiency of MSV10 problem detection. Two Stage Cooling Units The MSV10 is less accurate when used on two staged cooling units with different low & high D/Ts. If used in this application, the MSV10 calibrated D/T plus tolerance range must be greater than the cooling unit s highest operating D/T. Zone Systems We suggest that you follow the same procedure used for two speed systems, but be sure to wire the MSV10 to the leaving side of the zone control panel. Fail Safe Cool Heat Pump Systems On Fail Safe Cool Heat Pump Systems connect the B wire to MSV10 Y/O terminal and move the #2 DIP Switch (located on the upper left hand side of the circuit board) to the right or ON position. High / Low or Two Stage Heat System Use the same procedure as two speed units. Dual Transformer Systems Change to indoor single stage transformer. If you use an outdoor transformer and the condenser or heat pump blows a fuse, you will only receive a POWER OFF alert report. Heat Pump Thermostats If you have a heat pump system that activates the reversing valve in the HEAT CYCLE please see the instructions above for Fail Safe Cool Heat Pump Systems. Variable Speed Blowers A variable speed blower is designed to maintain a constant airflow (CFM) even with a change of static pressure on the system. If the static pressure increases due to a dirty filter or grilles closing down, the blower will compensate for this increased pressure and maintain the preset airflow (CFM). This type system should work well with our equipment by maintaining a consistent D/T. No corrections or adjustments are required. Note: Because the blower can power up as the filter becomes restricted (pulling the dirt through the filter) it may be useful to connect an air filter pressure switch to the "F1" terminal. This switch can send then an alert report if pressure becomes excessive. 39

42 Return to Table of Contents APPENDIX N: THE F1 & F2 AUXILIARY SENSOR TERMINALS You can use any switch or other device that is normally open and does not carry voltage to trigger an F1 or F2 fault condition. When a F1 or F2 sensor closes, you will receive an alert report that the F1 (or F2) IS CLOSED. Although the F2 input is default set to normally open it can be changed to be used with a normally closed device by moving the #1 DIP Switch (located on the upper left side of the circuit board) to the right or UP position. (Please note the F1 input can only be used with a normally open device). When the #1 DIP Switch is in the UP position and the F2 sensor opens, you will receive an alert report that the F2 IS OPEN. Because the sensors connected might vary by customer, it is important to write down in each customer s file the type of sensor that s connected to their F1 and/or F2 terminals. F1 Terminal: The F1 terminals are monitored only when the system is running and/or the blower is in the ON position. The F1 terminals are on a time delay equal to the SYSTEM DELAY TIME, which is default set at 20 minutes (except heat pumps are 30 minutes) but can be adjusted with the Set Up key. When a switch connected to the F1 terminal closes, it must remain closed for SYSTEM DELAY TIME before an alert report is sent to the central station. Examples of F1 Switches: air pressure switch, sail switch F2 Terminal: The F2 terminal is monitored any time the circuit board is on. It is not tied to the SYSTEM DELAY TIME. The F2 terminal will respond whenever, depending on the DIP switch setting, a normally open or closed switch has been tripped for three (3) minutes. Examples of F2 Switches: Water Alert Float Switch, Freeze control, Sump pump, etc. Note: Do not run any power through the F1 or F2 Terminals. The F1 is a normally open electronic contact and the F2 is a normally open or closed electronic contact. They are not designed to allow any current to flow through them. The terminals are connected directly to the microprocessor and will send an alert when they are closed. Connecting an active or live circuit to any "F" terminal will damage the circuit board. IMPORTANT NOTE: Do not connect Carbon Monoxide (CO) sensors or any other sensor that detects life-threatening conditions. The MSV10 is designed only for HVAC monitoring and does not dispatch emergency personnel. 40

43 Return to Table of Contents Water Alert Float Switch (in drain pan) APPENDIX O: INSTALLING THE WATER ALERT FLOAT SWITCH SmartWay s water alert float switch is a normally open sensor for detecting water accumulation that connects to the MSV10 (V 2.0) s always-active F2 terminal. This switch can be used in any area where water accumulation is a potential problem, such as the condensate drain pan, sump pump drain, etc. This sensor is a plunger type float housed inside a one inch PCV sleeve with holes in its base to allow water inside. There is also a bracket for mounting the sensor to drain pan wall or other support. On its top is a normally open switch with two wires for connection to the F2 terminal. Under normal conditions, gravity pulls the float down to keep the switch in the normally open position. When water accumulates 3/8 at the sensor s base, the float will raise enough to close the normally open switch and immediately send an alarm report to you. This switch can also be used in a condensate drain to detect blockage. Simply remove the float from the PVC sleeve and mount it in a ¾ to 1 tee in either the primary or secondary drain. Alternatively, a Beckett float switch (available through most supply houses) can also be used. Because this switch is sold normally closed, be sure to adjust it to its normally open configuration. Return to Table of Contents APPENDIX P: INSTALLING THE CUSTOMER ALERT SWITCH The Customer Alert Switch is used to allow the customer to generate a report from the MSV10 Equipment Monitor. Pressing the Customer Alert Switch for ten seconds generates a report. Installation: Locate the Customer Alert Switch where the homeowner can easily access it. The switch can be mounted using the two mounting screws or the two-sided adhesive tape. Connect the Customer Alert Switch to its RJ11 port (located third from the left on the lower edge of the MSV10 case) using a standard telephone line. 41

44 Return to Table of Contents APPENDIX Q: FREQUENTLY ASKED QUESTIONS TO CUSTOMER SERVICE REPRESENTATIVES This following are suggested responses for Customer Service Representative to give to customer questions or complaints concerning the MSV10. If the customer calls about a shining or blinking red light on the MSV10, just let them know that it s a normal status indicator light. If the customer says the light is blinking, that can indicate the monitor has detected a fault. Check to see if an alert report has been received for this customer. Assure the customer that the blinking light is a normal MSV10 function. There are times that the MSV10 computer is unable to send alert reports. The following are possible reasons why: 1. The thermostat may not be working In order to send an alert report, the MSV10 computer has to get information from the thermostat. If the thermostat is bad, you cannot receive an alert report for poor HVAC system performance. However, a report will always been sent if the house temperature goes above or below the MIN or MAX temperature settings. 2. Phone line is busy or someone is on the internet The MSV10 computer won't interrupt an ongoing call, but will wait until the line is clear before sending a report. When this happens the alert report will have the word "DELAYED" printed on it. 3. Our fax machine may have been busy. Very occasionally a report might be delayed due to a busy fax machine. 4. Power outage to the heating & cooling unit (the power switch to the unit is turned off or defective transformer). The MSV10 computer waits one hour before sending a power outage alert report. The customer can turn the fan switch to "on" to see if the system has power (if power, they can hear or feel the blower running). 5. Power outage to the house. Again, the MSV10 computer waits one hour before sending a power outage alert report. If the power was out, but restored within one hour, a power outage alert report is not sent. 6. The MSV10 computer calibration may need to be adjusted. Some customers are more sensitive to small temperature changes. We need to tighten up our monitoring range in those cases. 42

45 When the MSV10 HVAC Monitoring System sends a high "Delta T" (the difference in temperature between the return & supply air) or an Air Filter Switch ("F1") alert report, the following script may be useful in getting the customer to check their air filter: Customer Service Rep Alert Filter Blockage Script Hello, this is with. We are the company that installed your heating and air conditioning computer system. If you remember, this is the computer that checks the operation of your system 24 hours a day, 365 days a year. The computer has sent us a high-energy usage alert about your air conditioning & heating system. It appears there might be a problem with the airflow. A few simple checks might allow us to easily fix the problem. Have you closed down any air vents or supply air grills (the vents in the ceiling, floor or walls where the air comes out)? YES or NO If YES - Closing off too many grills to force air into other areas could damage your equipment. It is important to clean or replace your air filter each month because dirty filters can cost you hundreds of dollars on your electric bill and cause major damage to your outdoor compressor unit. Have you cleaned or replaced your air filter recently? YES or NO If NO If it's a throw away and is clean, then that's not the problem. If dirty, have them replace the filter. If it's a permanent filter, such as an electrostatic filter, have them clean it as follows: Most permanent filters are a heavy waffle weave of polypropylene fabric. The front (or face) of the filter has a weave with larger openings that allow the larger particles to pass through the face of the filter to the "accumulator chamber". If you look at the rear of the filter you'll notice that the fabric has very fine or small openings to trap the airborne contaminants from going into your living area. To prevent backwards installation, most filters also show the correct airflow direction. To really get a filter clean, you should first vacuum the front (face) to remove the large particles (like animal hair or carpet fibers). If the filter is close to the kitchen, grease accumulation may require spraying it with a household cleaner like "Top Job" or "409". Next use a hose (with the nozzle set on high-pressure flow) to "Back Flush" the filter for 2 or 3 minutes. "Back Flush" means that the water is sprayed into the filter's "small opening side" to push contaminants out the large opening front (face) side. Again, most filters show the correct water flow direction for "Back Flushing". If no, just be sure the water spray is opposite of the "Air Flow" direction. When you're finished, just let it drip dry for 10 minutes or so and you're done for the month. A good way to remember when to clean you filter is when the utility bill shows up each month! Note: If the electrostatic filter was purchased over the radio, at a home show or hardware store, check to see if it has a foam insert inside the filter. If so, we recommend they get rid of that kind of filter, as they are very, very difficult to clean without taking them apart. They restrict the airflow much more than any other type of electrostatic filter. 43
