Question about Honeywell Heating & Cooling
I am installing a Honeywell RTH230B Programmable thermostat, but I am unsure of which wires to connect to Rh and Rc. I have W, Y, and G hooked up. I still have red, orange, and blue wires coming from the wall. The installation guide states that the red jumper wire must be removed in 5-wire installations. So, which color wire goes in Rh and which goes in Rc?
First do you have a heat pump unit or standard a/c? standard a/c connections at the thermostat go like this red wire to rh-rc which is the 24v power and you don't have to remove the jumper.white goes to w which is the heating wire yellow goes to y which is the cooling wire green goes to g which is the fan wire and blue goes to c which is the common wire. so if your stat has rc- rh ywgc you should be set if the wires on the furnace correspond with the same alpha designation.orange may be used if u have a heat pump unit otherwise it may just be a spare you cap off and leave behind the subplate.
