QuestionHi Honeywell Support Team, Is this compatible with old Honeywell thermostats (image attached)? The old one does not have a model number written on it. If yes, can I switch it out myself or does it require a professional?
Asked 5 years ago by SG.
- Answer Yes. You should be able to unclip the faceplate and use the existing holes to install the new thermostat. The important issue is getting the wires in the right spots. This thermostat is very bright compared to the old one, forcing me to close the bedroom door.
