CHECKOUT:
1. Check For Short
- Disconnect the low voltage wires connected to "Y" and "G" at the thermostat subbase or EIM.
- Restart a call for cooling/heating from the thermostat and see if the WAIT timer expires properly.
- Responds Correctly = Low Voltage Short on "Y" or "G".
- Constant Flashing WAIT = Bad Thermostat
