HI,
CAN ANYONE SUGGEST ME WHICH IS COMPATIBLE PROGRAMMABLE WITH OLD HONEYWELL T87401165 THERMOSTAT. (I LIKED HONEYWELL T8602 D 2000). I DON'T KNOW IF THIS IS GOING TO WORK?
I HAVE WIRES CONNECTED TO (W1, W2, G, RC, RH, Y2,Y1 ) THESE TERMINALS. MY COMMERCIAL SYSTEM IS ON THE ROOF TOP. WIRE COLORS AS FOLLOWS.
WHITE, ORANGE, GREEN, RED, BLUE, BLACK, YELLOW.
ANY HELP IS APPRECIATED.
SANDY

this should be a relative simple, insure your new stat has [2] stages of heat & cooling, and is for gas/electric not for heatpump, some cane be programmed for both. you should have at least 8 wires, due to most prog. stats require a common or [c] terminal, so you will need 1 additional wire connection at new stat, befor removing old stat write down terminals & color of wires going to them, turn power off to unit, when installing new the terminals should be the same as your old stat, with of the exeption of an [c] terminal which will need to be connected, so stat will always have a constant 24v. source, which ever color wire is used for [c] will need to be connected at rooftop on the [c] terminal. turn on & program. [note your supplier should match you up with the stat that best fits your application, ask befor you buy, hope this helps, let me know. Antonetz r.p.
