Offset Instructions:
1. Read the return air temperature from the control interface (the installed return air temp sensor is measuring the return
air temp.
2. Using a different temperature measuring device, measure the actual air temperature next to installed return air sensor.
3. Get the difference to calibrate the installed return air temperature sensor via service menu:
