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.

I don't have a C cable for power to my new thermostat. What do I do?


Using a multimeter and reading for 24 volts will not provide the "common" leg of the 24 volt control power provided by your transformer, the other circuits besides RED, red being where the 24 volt "hot leg" enters the thermostat, the remaining circuits, heat or cool or fan will also read 24 volts to Red since it will read Common through the back door so to speak, the new NEST thermostats claim to need no Common leg for this reason however it will not work with every situation as far as the NEST goes. The only way to definitively know you have the Common leg of the 24 volt control power is go to the air handler and see what is on the C or Common terminal, Colors as stated as confusing and are only there to decipher the circuit as in cool or fan or heat etc. Common is akin to the NEG on a car battery, it is the side of power every 24 volt circuit terminates upon to complete its circuit, thus the common name. dont-c-cable-power-new-thermostat-cp4yufdp500qfugpjpa1ch44-1-0.png

If you are unsure about which wire goes where, that may be the source of your problem. The color coding can be confusing when changing from old to new. I pulled the instructions for my Honeywell CT3400A thermostat and found you can call Honeywell Consumer Services at 1-800-468-1502 M-F 7:30 am to 5 pm CT

I am replacing old 220 volt thermostat with a programable 220 volt thermostat. There are 6 wires in the box. (3 black & 3 red) There are only two black wires on the new thermostat. On the old...


Hi, this can be confusing. Be sure you have the power off before you wire it, but first you have to have an elect meter. The 6 wires in the box you will only use 2 of them. Cap the other 4 off. Use the 2 that have the correct voltage across them, 208, 220, 240 volts. The new stat is only set up for 2 hot wires 120 each. That will do it. Not to bad. be careful! Use care. Good Luck, Sincerely,

Replacing a thermostat


Typically if you are replacing a heat only thermostat you will have two or three wires. On the old thermostat these wires will be attached to terminals marked "R", "W" and maybe "G". Document what color wires goes to which terminal and transpose these to the new thermostat. If you have a heat and cool thermostat, you will have two or three more wires and connected to terminals labeled "C", "B" and "Y". Again, transpose these wires to the new thermostat as best you can.
