34 Point Module Supply Air Temperature (Universal Input 1) The supply air temperature sensor ships with the unit. The sensor wire is factory-provided and is preterminated in the unit. The sensor ships loose (in the control panel) and must be field installed downstream of the unit, with the probe in the supply duct. The supply air sensor is a 10kΩ thermistor (at 77°F), type III thermistor curve. Cooling Coil Leaving Air Temperature (Universal Input 2) The coil leaving air temperature sensor is factory wired and installed in the coil section of the unit between the evaporator and reheat coils, closest to the evaporator coil. The coil leaving air sensor is a 10kΩ thermistor (at 77°F), type III thermistor curve. Outside Air Temperature (Universal Input 3) The outside air temperature sensor is factory wired and installed on the outside of the unit under the outside air damper hood. The sensor is a combination sensor (temperature and relative humidity). The outside air temperature sensor is a 10kΩ thermistor (at 77°F), type III thermistor curve. Space Temperature (Universal Input 4) The space temperature sensor must be field wired and installed. Refer to wiring instructions in this manual. The space temperature sensor is a 10kΩ thermistor (at 77°F), type III thermistor curve. Outside Air Relative Humidity (Universal Input 5) The outside air relative sensor is factory wired and installed on the outside of the unit under the outside air damper hood. The sensor is a combination sensor (temperature and relative humidity). The outside air relative humidity sensor is a DC voltage device (0-10 VDC, 0-100% RH). Space Relative Humidity (Universal Input 6) The space temperature sensor must be field wired and installed. Refer to wiring instructions in this manual. The space relative humidity sensor is a DC voltage device (0-10 VDC, 0-100% RH). Damper End Switch (Universal Input 7) Units may be equipped with only the outside air damper (100% outside air only) or outside and return dampers (100% outside air with recirculation). In all cases, the damper actuator is controlled with a 0-10 VDC signal from the controller to the actuator. When actuators are included for outside and return dampers, both dampers are concurrently controlled with one 0- 10 VDC signal (opposing direction handled physically with the actuators). For applications with one damper actuator, the damper end contact closure is wired to the controller to indicate when the damper is open sufficiently for air flow. For applications with both outside and return dampers, the end switches are wired in parallel. In those applications, at least one end switch must close to indicate the damper is open sufficiently for air flow. Supply Fan Status (Universal Input 8) The supply fan status of the unit is determined with a differential pressure switch. The switch is mounted in the control panel with tubing running to the high and low pressure sides of the fan. When the fan speed increases enough to create the pressure differential, the contacts internal to the switch close, confirming fan operation. High / Low Pressure Cutout, Circuit A (Universal Input 9) Each refrigeration circuit (one or two compressors per circuit, depending on the unit) includes both high and low pressure switches. When the refrigerant pressure of the circuit exceeds the switch limit, the cutout device contacts open, causing a shutdown alarm. When the high pressure condition is addressed, the high pressure cutout device must be manually reset by pressing the red button on the device. When the refrigerant pressure of the circuit falls below the switch limit, the cutout device contacts open, causing a shutdown alarm. The low pressure cutout device automatically resets when the fault condition is addressed. High / Low Pressure Cutout, Circuit B (Universal Input 10) Each refrigeration circuit (one or two compressors per circuit, depending on the unit) includes both high and low pressure switches. When the refrigerant pressure of the circuit exceeds the switch limit, the cutout device contacts open, causing a shutdown alarm. When the high pressure condition is addressed, the high pressure cutout device must be manually reset by pressing the red button on the device. When the refrigerant pressure of the circuit falls below the switch limit, the cutout device contacts open, causing a shutdown alarm. The low pressure cutout device automatically resets when the fault condition is addressed. Controls V2 IOM 7 May 2011 Part Number 474626
