MULTI-TEC Control equence of Operation & Logic The MULTI-TEC unit programmable logic board uses a technologically advanced series of sequences to control unit operation. These sequences can be defined in the following processes: Alarm Logic Indoor Blower Control Temperature Control Free Cooling Operation Compressor Logic The processes listed are described in detail below. Alarm Logic High Mixed Air Alarm If the mixed air temperature sensor is above cooling temperature setpoint for longer than seconds, the wall unit will generate a high mixed air alarm. Low Mixed Air Alarm If the mixed air temperature sensor is below F for longer than seconds, the wall unit will generate a low mixed air alarm. Refrigerant Low Pressure When the low pressure switch indicates a low pressure condition and there is an active call for cooling, the controller will generate an alarm after a delay. The delay used by the low pressure alarm is determined by the outdoor air temperature. If the outdoor air temperature is below F, the delay is 0 seconds. If the outdoor temperature is above F, the delay is seconds. Additionally, if the outdoor temperature sensor is not used, the delay is set to 0 seconds. The controller will try to run the refrigeration system three (3) times before the alarm will lock the compressor out. Economizer Damper: When the controller commands the economizer damper actuator to a position other than 0% and the damper switch indicates the damper is not open after a delay of seconds, the controller will generate a damper failed to open alarm. When the controller commands the economizer damper actuator to the 0% position and the damper switch indicates the damper is not closed after a delay of 0 seconds, the controller will generate a damper failed to close alarm. Freeze tat Alarm: When the coil temperature is below F for longer than seconds, the controller will generate a freeze stat alarm. This will then change the blower to high speed and turn off the compressor for 0 seconds or reset once the temperature has reached F above the freeze stat temperature set point. Fan tatus Alarm If the fan is commanded on and the fan status switch has not indicated the fan is running within 4 seconds, the system will generate and alarm. Form No. 32-3 upersedes 32-7 Page 3 of
Indoor Blower Control The fan will be enabled if the system is set for continuous blower, economizer enabled, cooling stage, cooling stage 2, heating stage, heating stage 2, freeze stat on, or a run test is started. Temperature Control Zone election Based on the zone setting (average or highest), the unit will decide which zone control temperature to use. The control temperature is an average of the zone temperature sensors and the return air temperature sensors in each zone. Cooling equence (Economizer Available) Field-Adjustable If the zone control temperature is higher than 7 F and outdoor conditions are acceptable for economizing, the unit will enable the economizer. If the zone control temperature is higher than 0 F, the unit will enable mechanical cooling stage. If the zone control temperature is higher than F, the unit will enable mechanical cooling stage 2. Cooling equence (Economizer Not Available) Field-Adjustable If the zone control temperature is higher than the cooling setpoint, the unit will enable stage mechanical cooling. If the zone control temperature is higher than 0 F, the unit will enable stage 2 mechanical cooling. Heating equence: Field-Adjustable If the zone control temperature is below F, the unit will enable electric heat stage. If the zone control temperature is below 7 F, the unit will enable electric heat stage 2. If the zone control temperature is below F, the unit will enable electric heat stage 3. Free Cooling Operation Economizer Enable The economizer will be enabled for cooling operation if the following conditions are true: None Economizer will not be enabled. Bulb Only Field-Adjustable. Outdoor air temperature is below 70 F. 2. Indoor zone relative humidity is below 70% (with LC only). Temperature & Humidity Field-Adjustable. Outdoor air temperature is below 70 F. 2. Outdoor relative humidity is below % (without LC indoor zone humidity sensor) or 0% (with LC indoor humidity sensor). 3. Indoor zone relative humidity is below 70% (with LC indoor RH sensor only). Enthalpy (Temperature, Humidity & Dewpoint) Field-Adjustable. Outdoor air temperature is below 70 F. 2. Outdoor relative humidity is below % (without LC indoor zone humidity sensor) or 0% (with LC indoor humidity sensor). 3. The outdoor air dewpoint is less than F. 4. Indoor zone relative humidity is below 70% (with LC indoor RH sensor only). Compressor Logic Enable The compressor will be enabled when stage is enabled and outdoor air conditions are not acceptable for economizing. If the conditions are acceptable, the compressor will run when stage 2 is enabled. Delays & Run Time Field-Adjustable The compressor will have a minimum run time of seconds and a minimum off time of seconds. Form No. 32-3 upersedes 32-7 Page 4 of
tandard & Optional Accessory Functionality LC00 Controller: The LC00 is Bard s premier control device for electronics shelters, equipment buildings, pump houses and modular buildings. A logic board inside the LC controller communicates with logic boards in the MULTI-TEC units to decide when to cool the area, and what mode of cooling to use if economizers are installed. Cooling modes include unit rotation and intuitive load balancing. Energy efficiency and consistent area temperature control are maximized for reliable equipment cooling. Humidity monitoring inside the shelter helps reduce the chance of condensation forming on equipment and electronics and can be controlled with optional equipment. An N+ ( extra backup unit) operation or a localized load-based strategy can be used for better temperature control when using multiple units. The controller is able to be installed in any area inside the structure with the use of remote temperature sensors, and can operate with 3 separate zones or areas including office spaces and battery rooms. th-tune Controller (-24): The th-tune controller can be used to operate one unit independent of the LC controller. The th-tune acts as a simple thermostat and connects to one unit using standard Ga. twisted pair wiring. The TEC- EYE TM service tool (provided in the kit) is used to program and setup the MULTI-TEC unit. The th-tune controller does not connect to the LC controller and does not have remote alarming capability. EMI Ferrite Filter (-0): An EMI filter is used to suppress interference that may be present on the connecting (2) wire twisted pair between the MULTI-TEC units and LC controller. When connecting all units together in series through a daisy chain connection, a total of (2) EMI filters are needed. One filter is placed at the 2 wire connection to the LC controller. The other filter is placed at the 2 wire connection point where the unit at the end of the chain is connected. If two separate daisy chain connections are made, a total of (2) EMI filters are needed, one EMI filter is needed at the 2 wire connection point of each end unit. TEC-EYE TM ervice Tool (-0): The TEC-EYE TM service tool is used for system setup and troubleshooting. An easy to read backlit display and -button control is provided. Used as a display and interface, the tool is able to interact with the microprocessor on the logic board located in the LC controller and in the MULTI-TEC unit. A foot communication cable with RJ connectors is provided with the TEC-EYE TM. (Included with every LC00 & -24 th-tune control package.) Form No. 32-3 upersedes 32-7 Page of

The amount of outdoor air varies in response to the system controls and settings defined by the end user. It includes a built-in exhaust air damper. The economizer is designed to provide free cooling when outside air conditions are cool and dry enough to satisfy cooling requirements without running the compressor. This in turn provides lower operating costs, while extending the life of the compressor. tandard Features: Full rated outdoor intake Fully modulating Hi-Torque Actuator 7" intake hood with filter imple single blade design Positive shut-off with non-stick gaskets Electronic Enthalpy sensors PLC control module with precision settings and diagnostics High Pressure witch: Required afety Device that also provides protection to the compressor system when system refrigerant pressure is above an acceptable level.
