What Does Wait Mean on a Honeywell Thermostat?

The "Wait" message on a Honeywell Thermostat means the thermostat is waiting to activate the HVAC system. This is done to prevent damaging the HVAC system compressor. If the system is working properly, then "Wait" should disappear after a few minutes. It will then resume normal operation.

A thermostat is a device that controls a building's HVAC system. Basically, a thermostat will tell the HVAC system when to start heating or cooling and when to stop. Meanwhile, one of the most important elements for an HVAC system is the compressor. This is the device that circulates the refrigerant needed for heat exchange.

The Wait mechanism on a Honeywell Thermostat is designed to keep the HVAC system compressor functioning properly. An HVAC system needs a few minutes to adjust after being powered back on. If the compressor inside an HVAC system is activated too early, then could experience damage. This is commonly referred to as "short cycling".

By waiting a few minutes for the compressor to activate after the HVAC system is powered on, short cycling can be prevented. That is why the Wait feature is often implemented. For most Honeywell Thermostats, the Wait feature will keep the HVAC system compressor from running for five minutes. This is perfectly normal, and the problem should quickly address itself.

If the Wait message does not disappear after several minutes, then it could indicate there is a problem with getting proper voltage to the thermostat. In that case, further troubleshooting may be required. A voltmeter can be used to check whether or not the applied voltage is within the acceptable range. You should also make sure that there are no shorted or faulty wires. Sometimes simply powering of the HVAC system at the breaker and then waiting a few minutes before reapplying power can fix the problem.
