Honeywell Thermostat Flashing Return –How to Fix

Return is when the thermostat switches on the cooling/heating unit once the energy-saving period is over. We usually set the ‘return’ on the thermostat of the HVAC to represent our returning time. Programming the thermostat gives you a great way to reduce energy consumption bills.

Programming the unit is also essential in ensuring the device doesn’t operate non-stop, even when unavailable. So, if your Honeywell Thermostat keeps on showing a Return display, this article is for you. When choosing the right time for Return Time, it’s always advisable to develop additional lead time.

This implies that the amount of time is based on the exterior temperature and the unit’s typical response period. This allows the equipment to either cool or heat your house before you come back.
