A Honeywell thermostat does not function or display if there is no power to the HVAC unit. This is repaired by turning the circuit breaker to the HVAC unit on. A malfunctioning display can also be caused by lose wiring connections where the thermostat is mounted to the wall. This can be repaired by removing the thermostat and ensuring that the wires are securely connected and that the C terminal connects to the transformer. If this does not solve the issue, the circuit board can be bypassed by connecting the C terminal directly to the common leg of the transformer. Incorrect temperature readings can be resolved by moving the thermostat away from doors or windows. The temperature readings are most accurate when the thermostat is located near the center of the structure.
Honeywell thermostats have separate settings for heating and air conditioning. If a unit is not functioning, the problem may be resolved by ensuring the correct heating or cooling option is chosen on the thermostat. It can take up to five minutes for a Honeywell thermostat to respond to changes in the system.Learn more about Heating & Cooling
