G. Outdoor Air Temperature (OAT) Sensor (Provided)
The outdoor air temperature sensor is a 10K thermistor used to measure the
The temperature sensor looks like an eyelet terminal with wires running to it. The sensor is located in the “crimp end” and is sealed from moisture.
The user can read the value of the sensor using the Read mode, described in the
H. Supply Air Temperature (SAT) Sensor (Provided)
The supply air temperature sensor is a 10K thermistor located at the inlet to the indoor fan. This sensor must be field installed. The operating range of temperature measure- ment is 0° to158 F. See Tables 5 and 6 for thermistor resis- tance and resolution values.
The temperature sensor looks like an eyelet terminal with wires running to it. The sensor is located in the “crimp end” and is sealed from moisture.
The user can read the value of the sensor using the Read mode, described in the EconoMi$er+ Controller section.
I. Indoor Air Quality (IAQ) Sensor
Any indoor air quality or CO2 sensor that provides a 4 to 20 mA output can be used as the IAQ sensor. The controller will modulate the
Mount the sensor according to manufacturer specifications. In order to wire this sensor, an accessory
The IAQ sensor is wired to the ground and IAQ wires in the harness. The accessory

Sensor wiring should be extended with wire and wire nuts and routed to the IAQ sensor location. Adjust the IAQ set- ting at the controller to correspond to the IAQ voltage output of the sensor at the
J. Return Air Temperature (RAT) Sensor
The EconoMi$er+ controller will accept input from the acces- sory 10K return air temperature sensor (CRTEMPSN001A00) in addition to the outdoor air temperature sensor shipped with the EconoMi$er+. By using both sensors, the outdoor air and the return air temperatures are compared (differential dry bulb) for optimal energy savings. See Tables 5 and 6 for thermistor resistance and resolution values.
