Wiring a replacement Honeywell Thermostat
I purchased a Honeywell Vision 5-1-1 Day programmable thermostat to replace a Lennox thermostat (51H4301). This is an all electric heat pump type unit (Lennox HP 21-511-5P). According to the Honeywell manual, if the old thermostat has wires W1, Y1 and W2, some system modification is required. Call your local heating and cooling contractor for assistance. My old thermostat does have W1 and Y1 (not W2). It also has a Y2 which is not mentioned in the directions for the heat pump style (Y2 is in the conventional details). Is this wiring something someone could help me with or should I do as the manual states and get a heating and cooling contractor?
Thanks
