Note:
Tstat-Only set to No means all temperature
sensor inputs are active and usable, but Tstat inputs still have priority.
Inputs

- Evaporator coil temperature sensor EC1, EC2, EC3, and EC4
- 24 VAC to thermostat terminals Y1 through Y4
- 24 VAC to thermostat terminals W1 through W3
- Operational outdoor air temperature (OprOAT) from the sensor to the OAT terminal or a communicated value
