Good day! Thank you for your interest in our Honeywell RTH6350D1000 Programmable Digital Thermostat. According to Honeywell, we need to get the following information first before we can determine the compatibility of this thermostat:• Please specify the type of heating equipment you have. For e.g. is it a gas/oil forced air, electric forced air, hot water or a heat pump system?• Please let us know how many wires are coming out of the wall and how the old wires were configured, as in which color wire was connected to which terminal letter on the old thermostat.• If possible, please send us a picture of the existing wiring at the thermostat.• Do you have zoning (multiple thermostats controlling the same heating and cooling equipment)? If yes, please specify how the thermostats are zoned. For e.g. are you using dampers or panels?Please get back to us with these details so we can further assist you.
