8 SYSTEM MANUAL 3 General Description dyssey is a compact, DIN rail mounted, energy management system for single or multiple site control. With the power of a full energy management system and the simplicity and cost of a conventional controller, dyssey is the perfect tool to control, monitor and conserve energy in small/medium sized buildings. dyssey also affords the opportunity to manage single or multiple sites from one central location. It s application is virtually unlimited for those seeking to make positive in-roads towards achieving sound energy management practices. A key feature of the dyssey energy management system is the inclusion of 12 plant control schemes, which cover most conventional control applications. Each scheme is pre-programmed with default set-point values and timetable settings. Virtually no commissioning of the dyssey is required; a test scheme even helps check out the wiring and plant operation. The dyssey can be either DIN rail mounted or, as an option, be supplied in it s own purpose built, wall mounted enclosure. When DIN rail mounted, panel design is simplified by accommodating connecting cables in the control panel trunking, eliminating the need for wiring to the control panel door. The dyssey keypad and display unit can be either mounted on the control panel door or situated in an office up to 1000 metres away. Alternatively, if the dyssey controller is supplied in an optional enclosure, the display can be mounted on the front of this unit, which comes complete with fixing holes and a cable entry hole. In all cases cable connection is via a 4-core cable. Ease of operation and installation is complimented by total flexibility of control. dyssey can be used stand-alone, connected to a site based PC via hard wiring, or remotely through an optional telephone modem. The click of a mouse allows the operator to interface with the dynamic graphics supplied at no extra cost, interrogate alarms, data logs, degree-days, meter readings, and control and monitor any item of plant. Information is displayed graphically and can be constantly updated and adjusted. Issue 1c 3-1

10 SYSTEM MANUAL 4 Control ptions Boiler Control dyssey has the facility to sequence, either from flow or return temperature, and control up to 2 boilers. If more than two boilers are required the dyssey can supply a boiler n/ff signal to control a stand-alone sequencer. Duty changeover of Lead/Lag Boiler will occur daily and if boiler fault signals (high limit/lockout) are wired into the dyssey the auto changeover feature will ensure that a faulty boiler is set to Lag. (Excluding schemes 9 & 12) The boilers may be directly compensated from outside air temperature with a minimum flow temperature setpoint to ensure that any HWS services are maintained. A Boiler Early ff timer, adjustable from 0 to 60 minutes, ensures that the residual heat is dissipated from the boilers when the plant shuts down. HWS Hot Water Services Many of the standard dyssey schemes have provision to control HWS with two outputs; 1 for time control and the other for temperature control. If the scheme has an HWS diverting valve, then this is controlled by the temperature control output with both the primary and secondary pumps controlled by the time control output. If the scheme has only primary and secondary pumps and no valve then the primary pump is controlled by the temperature control output and the secondary pump is controlled by the HWS Pump Control utput. Control for stand-alone HWS systems that are independent of the boilers is provided and can be selected with soft switches during commissioning. Separate time and time/temperature outputs are still available. Remote Push Button Extension Timers All of the standard dyssey schemes have provision for push button extension timers for each controlled zone, HWS and any fixed time Start/Stop outputs.

14 SYSTEM MANUAL Periods of the Day The dyssey controller splits the day into 4 periods; ptimum Start, Day Time, ptimum Stop and Night Time. Comfort Temperature Frost Temperature Temperature Night Period ptimum Start Period Day Period pt Stop Period Night Period Start of ccupancy Time of Day ptimum Start dyssey will preheat the space temperature independently in each zone to achieve the desired setpoint by the start of occupancy. The optimum start algorithms are self-learning with maximum limits. Day Time Period The comfort temperature (pt Start Temp) will be maintained within this period. Economy ff If the utside temperature is within a number of degrees (set in the Heat Eco ff setting) of the zone comfort temperature (pt Start Temp) the output will switch off, provided that it has reached setpoint. The output will become active again if the outside temperature falls through a number of degrees set in the Eco ff Diff setting. ptimum Stop dyssey will start switching items of plant off as it approaches the end of occupancy time. It will do this as early as possible without compromising the comfort temperature. The optimum stop algorithms are self learning with maximum limits. Night Time Period This is the time of day where there is no occupancy. dyssey will give frost protection control during this period. Frost Protection dyssey offers both first and second stage frost protection. End of ccupancy First stage frost protection is invoked when the outside air temperature is below or equal to 1 C (adjustable during commissioning) and causes selected valves to open and pumps to run; thus circulating water and giving a degree of protection to peripheral pipe-work. Second stage frost protection is invoked when an individual zone temperature is equal to or below the zone frost protection setpoint (adjustable during commissioning) and causes the appropriate valves to open, pumps to run and the boilers to fire. Issue 1c 5-3

15 SYSTEM MANUAL Compensated Temperature Control dyssey adjusts the water flow temperature to compensate for variations in both outside and space/room temperature. utside Temp The outside influence setting adjusts the compensation slope by depressing the flow temperature by a number of degrees, set by the utside Slope setting, for every degree that the outside temperature exceeds the MD (Minimum utside Design) temperature. MD Temp Flow Temp Control Temp Room Temp The inside influence setting adjusts the compensation slope by depressing the flow temperature by a number of degrees, set by the Inside Slope setting, for every degree that the space/room temperature exceeds the reference temperature. Similarly, the flow temperature will be increased for every degree that the space/room temperature falls below the reference temperature. Reference Temp Flow Temp Control Temp Alarm Inputs Many of the standard dyssey schemes have provided for general-purpose digital alarm inputs as well as dedicated alarm inputs for boiler faults and pump trip signals. Analogue utputs: 0-10V Where possible both analogue 0 to 10 volt outputs and relay drive open/closed outputs have been provided for mixing valves and zone valves. Refer to the individual scheme diagrams for availability. Issue 1c 5-4

16 SYSTEM MANUAL Local Communication dyssey can be connected to a Personal Computer via a standard RS232 interface, using a suitable cable supplied by your stockist. This will allow the operator to use the advanced dynamic graphics, supplied at no extra cost with each dyssey. Remote Communication High speed, remote interrogation of the dyssey can be achieved by connecting it to a Hayes compatible modem. This can be supplied, complete with interface lead, by your stockist. Remote Push Button Extension Timers for Heating & HWS Remotely mounted, illuminated push buttons can be connected via a two core cable to the dyssey, allowing the time-tabled hours to be extended by 30 minutes or 1 hour, set at commissioning, for each button press. For example, one button press will cause the zone to be extended for an extra 30 minutes, two presses for an hour, etc, up to a maximum of four button presses. The button indicator lamp will flash to indicate the number of presses made. The extension timers will not start to time until the end of the programmed time-tabled period. Timetables and Holidays dyssey provides for independent timetables for each heating zone and HWS. Each timetable has two periods per day, giving 14 independent time periods per zone. The year schedule function allows automatic selection of summer, winter and holiday, that can be preprogrammed for up to a year in advance. During the summer period the heating zones are disabled, during holiday periods both heating and HWS are disabled. Frost protection for heating zones is always operative irrespective of the Year Schedule. Four separate holiday periods can be programmed in advance for one day and any number of days or weeks. Issue 1c 5-5

17 SYSTEM MANUAL Dynamic Graphics An advanced dynamic colour graphics package is supplied at no extra cost with each dyssey. This comprises of a single page plant schematic for each of the standard schemes, making dyssey extremely user friendly. The graphics offer full control of the dyssey; allowing the operator to alter control parameters, observe operations and view temperature/time graphs on screen. Current alarm status can be viewed, meter readings can be taken, and local degree day information uploaded. Data uploaded from the site controller can be stored on the PC for future reference and backup purposes. An example of an dyssey graphics scheme is shown below: dyssey graphics run under the Microsoft Windows 3.1, Windows 95 or Windows NT environments. A minimum hardware requirement would be: 486 PC running at 33MHz, with 8MB RAM Graphics card with 1MB RAM, capable of 1024x768 pixels with 256 colours SVGA monitor Issue 1c 5-6

23 SYSTEM MANUAL Soft Switches A series of Soft Switches are used in the dyssey to select different options, for example, 1 or 2 boilers in use. To change the state of a Soft Switch, enter the Global Settings option, refer to the Menu Structure page for the scheme in use. Select the Soft Switch required and press the Right key once to enter and a flashing up and down arrow will appear. Use the Up or Down keys to change the state to n or ff. Details of the Soft Switch settings are shown with each Control Scheme. Issue 1c 6-6

24 SYSTEM MANUAL Setpoint Definitions dyssey uses an extensive range of setpoints that are explained in this section. The setpoint names appear in italic text, depicting what can be seen on the dyssey display menu system. Frost Temp Minimum inside temperature, measured by any room sensor. Used to protect the fabric of the building. pt Start Temp Target zone comfort temperature to be obtained during occupancy. Heat Eco ff This defines a band below the pt Start Temp. After reaching setpoint, and if the outside temperature is within this setting, the output will be turned off. Eco ff Diff The output will become active again if the outside temperature falls through the number of degrees specified in this setting. Max Rise Rate and Max Fall Rate The maximum times that the system can self-learn to, measured in minutes per degree. Max Rise Rate applies to the ptimum Start Period of the day and Max Fall Rate applies to the ptimum Stop Period of the day. Control Temp Control temperature set for boilers, valves & Domestic Hot Water. Minimum Temp and Maximum Temp Upper and lower limits for Control Temp. utside Slope The compensation slope is adjusted by this setting as follows. The value that is set for Control Temp is the flow temperature at minimum outside design temperature (M..D.) fixed at -1 C. For every degree that the outside temperature exceeds M..D. temperature the flow temperature will be depressed by a number of degrees set in this value. The utside Slope setting should be calculated by taking the number of degrees per degree required and multiplying by eight. For example, for a setting of 3 degrees per degree the utside Slope value will be 3 * 8 = 24. If the Control Temp is set at 80 C, the MD temp is -1 C and the utside temp is 10 C the flow temp will be depressed by 33 C. ie. The utside temp is 11 C above the MD temp, multiplied by 3 degrees per degree = 33 C. Issue 1c 6-7

25 SYSTEM MANUAL Inside Slope The compensation slope is adjusted by depressing or raising flow temperature with reference to the zone temperature. For every degree that the Space/Room temperature is less than the Reference Temp the flow temperature will be increased by a number of degrees set in this value. Equally, for every degree that the Space/Room temperature is above the Reference Temp the flow temperature will be depressed by a number of degrees. The Inside Slope setting should be calculated by taking the number of degrees per degree required and multiplying by eight. For example, with settings as follows: utside Slope 24 (3 degrees per degree) Inside Slope 32 (4 degrees per degree) Reference Temp 19 (Required temp in zone) Control Temp 80 (Flow temp at MD temp and comfort) MD Temp -1 C utside Temp 10 C Room Temp 17 C The utside temp is 11 C above the MD temp so depression due to outside influence will be 33 C as above. Room temperature is 2 degrees below Reference Temp so the mixed flow will be increased by 8 degrees. Mixed flow = = 55 C Reference Temp The required temperature in a Zone. HWS Sec Pump /Run Timed over-run of a pump to dissipate heat. Advance ff Prior to the end of occupancy, the Heating Boiler will be switched off in advance of the Heating Pumps. Issue 1c 6-8

124 SYSTEM MANUAL The dyssey energy management system controls the heating within your building to ensure that comfort conditions are maintained with maximum energy efficiency. Although the dyssey operates automatically for normal day to day use, you may find it necessary to make adjustments to the settings for changes to timetabled periods of occupancy, or to temporarily extend the normal operating hours, or to set holiday periods, etc. A simple menu structure allows you to view or make changes to settings and to view actual temperatures and the status of the heating plant. Refer to the Menu Structure page for your system. Four buttons allow you to navigate around the menu structure; up, down, left and right. See the section How To... Navigate the Menu Structure. The front panel of the dyssey is also fitted with two indicating lights, HEALTHY and ALARM. Under normal conditions the green HEALTHY light will flash. If it stops flashing there is a fault. Contact your supplier. The red ALARM light will be FF if there are no alarms, it will FLASH when there is an alarm condition that has not been accepted, and stay N if there are still alarms but have all been accepted. In addition, an audible alarm will sound if there is an alarm condition that has not been accepted. An alarm condition can occur to indicate a failure of the heating system. See the section How To... Deal with Alarms. Issue 1c 10-3

128 SYSTEM MANUAL 4. How To... Change the Temperature in the Zones. Refer to the Menu Structure page for your system. This will indicate which temperatures you are able to alter. A great deal depends upon the heating system that the dyssey is controlling. For example if you change the Comfort Temperature for "Heating Zone 1" the system might be able to control at this temperature throughout the day, or it might simply attempt to be at this temperature at the start of each day and use other factors for control thereafter. Referring to the Menu Structure, use the buttons to move to the required setting (for example Comfort Temperature for "Zone 1" or the Frost Temperature for "Zone 2"). pt Start Temp 19.5 To change the temperature press the right button (may be subject to passcode) The display now shows a flashing vertical arrow: Frost Temp 19.5 Press the up/down buttons until the display shows the required temperature. Press the right button again to make the change. 5. How To... Change the Times of the Heating. All times are set using the 24 hour clock. Each day of a timetable can have 1 or 2 periods. This means that, for example, the zone could use one period and be at the required temperature from 09:00 to 17:00, or use two periods and be at the required temperature from 09:00 to 12:30 and then again from 13:30 to 17:00. The times that you set in the timetables should be regarded as "occupancy times", that is you only need to specify the times people will be in the zones. The heating systems will not necessarily be on at exactly these times, the system is automatically set so that the heating will operate as required to maintain comfort conditions during these times. Refer to the Menu Structure page for your system. This will indicate which times you are able to alter, use the buttons to move to the required setting. Zone 2 Wednesday 1 08:30-16:45 To change the time press the right button (may be subject to passcode) The display now shows a flashing vertical arrow: Zone 2 Wednesday 1 08 :30-16:45 Press the up/down buttons until the display shows the required setting for hours. Press the right button again to make the change and move to the next setting. Repeat the process until all settings (on time hours, on time minutes, off time hours and off time minutes) have been made. Issue 1c 10-7

129 SYSTEM MANUAL 6. How To... Cancel Part of a Timetable. Set both the on time and the off time of the relevant period to midnight: Zone 1 Mon 2 00:00-00:00 This period of the timetable is then cancelled and displays the message "Unused". 7. How To... Temporarily Extend the Working Hours. Your system may have push button extension timers. If so, the system will extend the working hours for 30 minites or 1 hour (depending on how the dyssey has been programed) for each button press. For example, one button press will cause the system to run for an extra 30 minutes, two presses for an hour, etc, up to a maximum of four button presses. The button lamp will flash to indicate the number of presses made. Another way to organise overtime is to use the "extensions" feature since this can be programmed in advance to fit your requirements more exactly. These extensions are temporary alterations to timetables. They enable the heating for periods that the timetables do not cover. They differ from timetables in that when the extension is complete it self-cancels. You can pre-program an extension up to one week ahead. Refer to the Menu Structure page for your system. This page will indicate which zones you can extend, use the up/down buttons to move to the required setting. Zone 1 Ext No 1 Unused If the required extension is free the screen will read "Unused". If the required extension displays times then the extension is already programmed and you should only alter the extension after careful consideration. Issue 1c 10-8

130 SYSTEM MANUAL To set up or alter the extension press the right button (may be subject to passcode) The display now shows a flashing vertical arrow: Zone 1 Ext No 1 Wed 10:15-10:15 Press the up/down buttons until the display shows the required setting for day. Press the right button again to make the change and move to the next setting. Repeat the process until all settings (on time hours, on time minutes, off time hours and off time minutes) have been made Zone 1 Ext No 1 Sat 09:00-12:30 8. How To... Cancel an Extension. Your system may have push button extension timers. To cancel an extension made with these buttons, hold down the button for 5 seconds. The button will stop flashing. If a programmed extension is set it may be cancelled in the following way: Refer to the Menu Structure page for your system, this page will indicate which zones you can extend. Use the buttons to move to the required setting. The screen displays the current setting, for example: Zone 1 Ext No 1 Sat 09:00-12:30 To cancel the extension press the right button (may be subject to passcode) The display now shows a flashing vertical arrow: Zone 1 Ext No 1 Sat 09:00-12:30 Press the right button again to move to the next setting (hours). Set the on-hour so that it is the same as the off-hour. Repeat the process until the on times (hours and minutes) and the off-times (hours and minutes) are the same as one another. Zone 1 Ext No 1 Sat 12:30-12:30 The extension is now cancelled and displays the message "Unused". Issue 1c 10-9

131 SYSTEM MANUAL 9. How To... Program a Year Ahead. The dyssey enables you to preset the following for up to a year ahead: The number of weeks in a year (either 52 or 53). A "Summer" period when the heating would be programmed off, but any hot water would remain in operation. The times when British Summer Time is in force so that the clock changes to BST and back to GMT automatically. A number of "Holiday", periods when all heating and hot water would be off (although frost protection still remains in force). In addition, it is possible to switch to a "Normal", "Holiday", or "Summer" operation manually. You should set/reset your year timetable at least once a year, cancelling any holidays you have set. This is because, for example, the Easter Holiday is at a different time each year. 10. How To... Preset the System for BST and GMT. Referring to the Menu Structure, use the buttons to move to the required setting. BST From - To Unused To change the time press the right button (may be subject to passcode) The display now shows a flashing vertical arrow: BST From - To Sun 00 - Sun 00 Press the up/down buttons until the display shows the required day. Press the right button again to make the change and move to the next setting. Repeat the process until all settings (on-day, on-week, off-day, off-week) have been made. Important note: be sure that you have set the week correctly. Not all diaries agree about week numbers and whether a week starts on a Sunday or a Monday. The dyssey treats the start of a week as a Sunday. Issue 1c 10-10
