Customer Question

I'm considering changing my current...

I'm considering changing my current TA 2000 thermostat to a 7 day programmable Honeywell TH 8320U1008. The TA 2000 has 7 connections W2 (black), O (orange), X (blue), R (red), Y (yellow), G (green) and E (white), with a jumper wire from W2 to E. The TH 8320U1008 has 6 connections RC, R, W, Y, G, and C or RC, R, O/B, Y, G, C. Can you tell me which wires go where? Thanks

Red to Rc with jumper to R Orange to O/B Yellow to Y Green to G Blue to C White White to W Black tape off seperate. Russ

Customer reply replied 10 years ago

In other Honeywell literature it says this model has terminal designations of: R,RC,W,O/B, W2, Y, Y2, L, E, C, S1, S2. Does that change things? Would the Black go to W2? I assume S1 and S2 are the indoor and outdoor remote senors, which one is which? Thanks.

HVAC Technician: gotoman for ac, HVAC Technician replied 10 years ago

You have two ways to wire thermostat depending on if unit is a heat pump or conventional. On new thermostats with the heat pump wiring we tape off black wire and just jumper W2 to E . The S1 and S2 are connections for an outside two wire sensor. Russ

Customer reply replied 10 years ago

Yes it is a heat pump. The existing thermostat has the black connected W2 and white to E as well as a jumper between both. This that the second way you refer to?

HVAC Technician: gotoman for ac, HVAC Technician replied 10 years ago

Yes you can connect the wires that way. Just some techs wire thermostat different. White to E and Black to W2 with jumper will work fine. Russ
