HVAC WIRING DIAGRAMS

Conventional Heat/Cool Single Transformer (Use Jumper)

Return air temperature can be measured by attaching an 8052 sensor to the RAT terminals.. The return sensor must be enabled in the installer set-up menu.. The return air temperature sensor provides protection in the event that the equipment control module loses connection with the thermostat. In the event that the thermostat connection is lost, the equipment control module will use the return air temperature sensor to maintain a temperature greater than 40°F and less than 100°F..

1.Locate the Aprilaire Model 8052 sensor in the return trunk..

2.Mount the sensor according to the installation instructions provided with the sensor..

3.Wire the sensor to the equipment control module RAT terminals..

Leaving Air Temperature Sensor (Optional)

Leaving air temperature can be measured by attaching an 8052 sensor to the LAT terminals.. The leaving air temperature sensor measurement is displayed during the installer test for diagnostic purposes..

IMPORTANT

Do not mount the sensor in direct line-of-sight of the heat exchanger, cooling coils, or UV lights as this may cause the sensor to report false temperature readings..

1.Locate the Aprilaire Model 8052 sensor in the supply trunk, after the heat exchanger and cooling coils. (See shaded areas in figure below..)

2.Mount the sensor according to the installation instructions provided with the sensor..

3.Wire the sensor to the equipment control module LAT terminals..
