How many wires do you have and what color are they?
Red is power to the thermostat, White generally goes to W1, yellow to cooling Y terminal, Green to G terminal. If you have different colors the set-up may be a little different. You can check at the unit which should have a terminal board which would also indicate which wires go to which terminals.

Havc thermostats


I will assume you did not write down what color wire you took of each letter on old thermostat? Sometimes color of wire doesn't matter as some installers will use whatever color. If you noted where each wire was on old thermostat, just put same color wire to same letter on new one. Under normal situation. y is for compressor (cool) G, is for fan (on AC) , RC is 24 volts from transformer for AC side, RH is 24 volt transformer from heat/furnace, and W is for other wire from furnace, is furnace is only 2 wire system. Was there any wire connected to A on old thermostat?

Outside a/c unit hasnt powered on yet and I want to make sure my RH and RC wires are correct.


Connect the red to RH

Go down to the furnace and look at the circuit board and note what color's go where. Most units only use 4 wires.

Should be
RED to RH
YELLOW to Y
WHITE to W
GREEN to G

Then from there two wires go to condenser outside. And they connect to Y and C on the board. Most of the time Red and White from outside. Don't get confused with Red coming from thermostat. Let me know Ken

No cool air. Thermostat AUX light turned on


I suggest you call a qualified service repair man. There are as many ways to connect a heat pump as there are people doing them. Nothing is standard industry wide that has anything to do directly with color codes, so it would be meaningless to go into them here. The terminals may be adapted to standard but but the thermostat manufacturer may not follow any terminal designations.

However you may just have an extra wire touching one of the terminals inside the thermostat. You can check this by removing the cover. Look where the wires attach to the terminal screws on the thermostat. Sometimes a new service person cuts the insulation back too far here or in the outdoor or indoor units and a "whisker" from one wire can touch the other terminals. A whisker is not the normal case try and move it away from another terminal if its is touching there. However, you may have jumpers in place especially if you have W, W1, W2... at any of the 3 sections, meaning the outdoor, indoor and thermostat.

If you can tell me the terminal designations R,Y, W1, W2, E, G, O, (B)... at the thermostat and the color thereon each, then at the indoor unit terminals or wire designations and the color there, then at the outdoor unit and the color thereon each terminal or wire designation there. I might be able to help if the above whisker check you don't find anything.:

GOto the iside unit itself. and remove the door and look for a terminial strip that the thermostat wires from the thermostat connects to and write down the colors wires and the letters they're connected to and connect the same to the thermostat .... they should be... r--red=power w-white=heat y--yellow=cool g-- green=fan! See which wires/ colors they're not using and bend back! Thank-you-very-much!

Not heating


Yes, the reversing valve has a separate coil. some energize on cool mode, some on heat mode. Has the thermostat been replaced? I find this a common mistake.
