First, take the old thermostat off the wall.

there should be different colored wires coming out of the wall still connected to the old thermo.

on the new thermo, there might be a wire color chart in the instructions or on the inside of the new thermo.

You should be able to line up the colors and install them that way. let me know if you have any other problems

I am installing honywell thermostat rth111/rth221 old thermostat has two wires that are yellow and need to know where to hook up


First things first. What type of system? Heat only, boiler or furnace? Central cooling.
Do NOT take wires off the old thermostat yet, or mark the color wire, to the terminal letter. Most times W,Y,G,R, terminals and maybe even a C terminal.

Your new thermostat should have the same letters. Sometimes they mix up color wire with terminal letters...... example (yellow wire to w terminal)
Also turn off power to equipment it is controlling. It is not high volts but you can short out the transformer. Hook uo wire color to same letter terminal on old stat, to new stat. Thats it.

Old mercury thermostat, New furnace wiring issues


Two wire hookup on the old thermostat tells me that it was set up for heating only. You will most likely need a modern thermostat. But in the meantime try this with the old one. The two red wires on the furnace are probably Rh & Rc. If so these can be put "together" on the R terminal on the old stat. The two W's on the new furnace are probably W1 &v W2 This is for first and second stage heat. You can put the two "together" on the W terminal on the old stat. Do not hook up the greens (blower fan wires). Do not hook up the blue wires (They would go to the Y terminal on a modern stat for airconditioning.
Who ever sold you the furnace should have offered you a new thermostat.
Good luck....

It sounds like your reversing valve energizes the opposite from how you wired it at the thermostat. Check the instructions.
