The majority of Honeywell thermostats are appropriate for your HVAC system. The thermostat may turn off and be on energy-saving mode for a more extended period; there is a possibility that it might turn back on to power and show that it is in recovery.

Nevertheless, it could take place without being scheduled. Generally, it happens after inconsistent and unpredictable thermostat changes. If this happens with your device, you should reset it to clear the settings.
