How do I wire a Honeywell thermostat


Can I start by saying I am not in anyway saying to do this alone it is dangerous but if u must follow each step start by being safe shut off the breakers good luck here to help
Step 1
Turn the air conditioning and heating unit off by flipping the appropriate circuit breaker. Test the unit to make sure it's off by turning your existing thermostat to the "On" position and seeing if it turns on. Wiring a Honeywell thermostat when the circuit breaker is on could cause you to blow the transformer that powers the HVAC unit Step 2

Connect the red wires to the thermostat RH, thermostat RC or thermostat R terminal. The thermostat RC terminal has a jumper wire between thermostat RH and thermostat RC. The thermostat R terminal operates both the heating and cooling units, and contains an internal jumper wire. Basically, your red wire on a Honeywell thermostat is the hot wire that run. Step 3

Run the green wire to the thermostat G terminal. The green wire controls the relay that operates the blower, and it controls the fan. Step 4

Control your air conditioning when you connect the yellow wire. It connects to the thermostat Y terminal Step 5

Hook the white wire to the thermostat W terminal to control the heating unit

I am wiring a Honeywell wifi unit and I used a separate 24v transformer and connected to the c and rc terminal. My system is ac and heat and uses both and rc and rh wire. I wired the rc to the r ter


A thermostat is a switch. It connects 24vac from one terminal to another depending on the request. The 24vac comes from a transformer, usually located in the furnace and connects to the R terminal. Since you are using RH and RC without a jumper between it means there are two transformers, one in the furnace for heating (RH) and one in the air conditioner condenser used for cooling (RC).
Your old thermostat was probably mechanical and did not have a C (24vac common) terminal. Your new thermostat requires power to operate therefore needs a wire connected to a C terminal. I would get rid of the transformer you added and look for an unused wire in the bunch at the thermostat. If it's there connect it to C on the thermostat and to C on the furnace. Remove any jumper from R to RC or from RH to RC depending on your thermostat and connect wires same as the old thermostat.

Wiring with only 2 wires; which terminals to connect?


See RC and RH, RC is for cool, RH is for heat, you wire the red wire to the RH or red terminal ,either one will work actually but we generally switch the hot leg of power, W is the heat circuit

I would like to know how to wire honeywell dt90e thermostat which wires where i have 5 wires from wall


It helps to know which wires went to the terminals on the old thermostat, if it had one. Otherwise, you would really need to know how they are hooked up inside the furnace/air handler. Some technicians hook them up differently, but I can give you the basics and most commonly used wires. R terminal- red/power wire G terminal- green/ fan wire Y terminal- yellow/ cooling or condenser wire W terminal- white/ heating wire C terminal- blue/black/ common or ground wire If you have a rc/rh terminal, they are usually jumpered with a small wire and your power wire still hooks to that. Hope this helps and good luck!

Removed my non programable Honeywell RT 5220D replaced it with a Honeywell RTH6350D to run my Goodman Heat Pump. First I labeled the wires then connected wires as follows: AUX, G, C, O/B (orange wire)...


Leave the factory jumper between R & RC. Connect the wires to the new stat just as you have them labeled. Use a piece of thermostat wire to make a jumper from AUX to E terminals. Your new thermostat should give you instructions on how to access the installer set up. You are going to set it up as heat pump with aux. I see this is 2 days old but if you need any help let me know.

Installation manual (pg. 6-7)states - "Remove Jumper if you have both R and RC wires" I only have the 'red'. But with the jumper in the way I can't get the red wire into the 4th terminal. So should I...


No keep the jumper, you should be able to get the red wire in under the little peice of mettal that the jumper is under but just on the other side of the screw, The red wire can go on either the Rh or the Rc terminal along with the jumper. If all else fails just put a wire under Rh and another wire under Rc and then wire nut the red Rh and Rc wires all together.

I have installed a Honeywell CT8775C, when I put it on the heat the A/C goes on!! I have checked my wiring and everything looks right? what should I do to correct it.


You should have a minimum of four thermostet wires. The red wire goes on the R terminal. White wire on the W terminal. Green wire on the G terminal. Place the yellow wire on the Y terminal. In most cases NO other terminals are used...... IF YOU DO NOT HAVE A YELLOW WIRE...... place the blue wire on the Y terminal. This should hopefully fix it. IF NOT....See if the thermostat has a RH and a RC terminal. If so I'll bet that you put the red wire on RC ternimal. this is for airconditioning ONLY. The RH terminal is for heating ONLY. Put a small jumper wire that will connect RH & RC. Then this should solve your problem.
