Unit Shutdown Input Displays the status of the unit shutdown input (Universal Input 16) of the controller. When the input contacts are closed, the unit is allowed to run. When the input contacts are open, Shutdown is initiated (supply fan off, all heating and cooling off, outside air damper closed). View Only Range: Run, Stop Occupancy Input Represents the status of the hardwired occupancy input, Universal Input 15 on the controller. When the hardwired occupancy input is Closed, the input is Occupied. When the hardwired occupancy input is Open, the input is Unoccupied. View Only Low Limit Input Represents the status of Universal Input 7 on the expansion module, and is used for a hardwired low limit stat supplied with units ordered with hot water heat. View Only Range: Normal, Alarm Head Press AO Displays the signal in percent Speed being delivered to the head pressure control VFD, to maintain the condensing temperature in cooling mode and suction temperature in heating mode. View Only Head Press DO Displays the status of the head pressure control digital output, to maintain the condensing temperature in cooling mode and suction temperature in heating mode. View Only Reversing Valve Displays the status of the reversing valve digital output, the digital output will be off when in cooling mode and on in heating mode. View Only Software Version Displays the version of the application software in the controller and should not be edited. Editable Default: r31 Defrost Mode Reflects the status of the air source heat pumps defrost mode Defrost mode will be initiated when the suction pressure drops below the outside air dewpoint minus an offset for a reset period of time. When in defrost mode the all controlled condenser fans will turn off and the unit will run in cooling mode to heat up and melt the frost built up on the outdoor coil. View Only Range: True, False Controls V2 IOM 20 May 2011 Part Number 474626
Status Supply Air Temp Measured by the field installed (factory provided) sensor located in the supply duct immediately downstream of the rooftop unit. The sensor is a thermistor (type III) and is wired to Universal Input 1 at the controller. View Only Space Temp Measured by the field installed (factory provided if ordered) sensor located in the space/room served by the rooftop unit. The sensor is a thermistor (type III) and is wired to Universal Input 4 at the controller. View Only Range: -20 to 20°F Default: 0°F Space RH Measured by the field installed RH sensor located in the space/room served by the rooftop unit. That sensor provides a 0-10 VDC signal to the controller, Universal Input 6, that corresponds to the space relative humidity: 0 VDC = 0% RH, 10 VDC = 100% RH. View Only Space Dewpoint Calculated based on the field installed (factory provided if ordered) space temperature sensor and field installed (factory provided if ordered) space humidity sensor. View Only Coil Leaving Temp Measured with a thermistor (type III) factory installed at the discharge side of the evaporator coil. The sensor is wired to Universal Input 2 on the controller. View Only Outside Temp Measured by the factory installed sensor located under the weather hood near the outside air dampers of the unit. The sensor is a thermistor (type III) and is wired to Universal Input 3 at the controller. View Only Outside RH Measured by the field installed RH sensor located in the outside air inlet hood of the unit. That sensor provides a 0-10 VDC signal to the controller, Universal Input 5, that corresponds to the outside air relative humidity: 0 VDC = 0% RH, 10 VDC = 100% RH. View Only Outside Dewpoint Calculated based on factory installed RH sensor and factory installed outside air temperature sensor. View Only Space Effec SP Represents the active space temperature setpoint being used for control purposes. Depending on the heating or cooling operation of the unit. View Only Supply EffecSP Represents the active supply temperature setpoint being used for control purposes. Depending on the heating or cooling operation of the unit. View Only Space Static Press Displays the interpreted value of the voltage read from the space static pressure sensor. The space static pressure sensor should be field installed in the space/room served by the rooftop unit. The output signal from the sensor must be 0-10 VDC. The space static pressure sensor, when used, must be connected to Universal Input 12 on the 34 point module on the controller depending on the configuration of the ventilator. For the sensor voltage to be interpreted correctly, the conversion scale and offset values must be set up correctly for that device (refer to the Appendix). View Only Stpt Slider Measured by the field installed (factory provided) sensor located in the space/room served by the rooftop unit. The slider is wired to Universal Input 14 at the controller. View Only Exh Air Temp Measured with a thermistor (type III) factory installed at the exhaust side of the heat wheel. The sensor is wired to Universal Input 2 on the expansion module of the controller. View Only Space CO2 Measured by the field installed CO2 sensor located in the space/room served by the rooftop unit. That sensor provides a 0-10 VDC signal to the controller, Universal Input 5, of the expansion module that corresponds to the space CO2: 0 VDC = 500 ppm CO2, 10 VDC = 1500 ppm CO2.
