Thermostat wiring help
With the winter approaching, I thought to take some time to review / update my condo's heating. Sealed the windows, installed window and door weather stripping. While doing all that, I came across my 5-yr old RiteTemp 8022C thermostat and had a thought to upgrade it.
I have 12 SEER Bryant heat pump with an indoor air handler that is equipped with a 10KW heat strip. The HVAC system is all electric, and, if I understand it right, it is 1 stage cool 2 stage heating system.
So back to the issue. I noticed that my indoor thermostat is currently wired with 5 wires as follows:
Black wire on C terminal
Red wire on RC terminal with a jumper wire to RH terminal
Orange wire on O terminal
White wire on W terminal with a jumper wire to Y terminal
Yellow wire on Y terminal
Green wire on G terminal
So now, I am thinking: does the wiring as I have it right now make the aux. heat come on together with the stage 1 heat (i.e. compressor)?
Then, I looked at the new programmable thermostats by Honeywell and Lux. And from what I can tell for 1 cool 2 heat systems they have W1, W2 Y1, Y2 terminals.
As I have it right now, there are 5 wires that are fed to the indoor thermostat:
C terminal wire - black
RC terminal wire - red
O wire - orange
W wire - white
Y wire - yellow
G wire - green
The question I have is what thermostat do I need (if the new ones have W1 Y1 terminals and currently my wiring is as described above).
Am I right in my statement that I have a single stage heating system with aux. electric heat, i.e. 1 cool 2 heat system?
Thanks in advance!
