my duo-therm is a 5 button at this point it will not dieplay heat pump but the heat is coming out of vents is my thermostat bad

If the heat pump is working and you can turn it off and on and also use the a/c, then the trouble is probably just the display on the thermostat, not the action of the thermostat. You can live without the word being displayed. A new thermostat is easy to install and cost about $100 through Amazon. On the other hand if heat is coming out when you are trying to use the a/c, the heat pump is not working correctly and you will need a qualified service technician.

There should be 5 terminals on the control module, which connect to the thermostat. They are marked like "Y, W, R, G, C" stand for Yellow, White, Red, Green, and Common. I disconnected the "R" wire and connected the switch in between. The two wires you talked about might be the one went to the out door unit (24 V). Double check it by following it where it goes to. You can also check your thermostat two see how many wires are used.

Below is the install manual - yes it is for a heat pump and has a hold button. I would check you wiring to insure it matches what shown in the install manual.http://cache.air-n-water.com/manuals/honeywell-th6220d1028.pdf

I have a number of them installed for separate zones. My heating system is forced hot air my supply is natural gas. I have a natural gas furnace. I do not know the differences between the pump and the furnace. Generally thermostats test for temperatures, depending on their level they will send a signal of ON or OFF. I imagine they should work in most applications.

Does it do anything at all? Did you slide down the safety? Do you hear the click or hear gas coming out when you hold the button down? Are you positive you filled it properly? If its full and the button depresses (safety disengaged) but no gas comes out when you hold the button, you probably have a gas flow problem. If the button depresses and you don't hear the click of the spark... you probably have an issue with the ignition. Just be sure you're using it right before you decide its actually a bad unit. If its full and sparks properly... maybe also check the flow adjustment on the side to make sure its turned up enough.

It is hard to say without knowing all the variables. Check your other working valves and make sure all connections are the same. Make sure the valve is seated properly... it can be easily misaligned when twisted on. Make sure your thermostat is set to operate that zone. Make sure that the manual valve controlling the flow from furnace in that zone is in the open position. And make sure your valve is set to automatic for thermostat control. I had work done in the hose, and for a year the heat in one of my 3 zones was funky. The valve in question was hard to see. When I finally checked it carefully, one wire was loose and the valve itself was not flush with the base. The zone was on all the time. I assume the other zones work, therefore the circulating pump is working. I am an amateur tinkerer. Most household things aren't rocket science, but if I can't figure it out, I call an expert.

I can think of a couple of possibilities: 1. The thermostat may be malfunctioning and calling for heat continuously. A thermostat is basically a temperature controlled switch. When it calls for heat it completes a circuit that sends voltage to the heating system (the Taco valve head in my system), and when the room temperature reaches the set point the thermostat opens the circuit and the heat should go off. 2. The water valve for a zone in the house may be stuck open. Check the Taco valve head for the zone in question and make sure the manual bypass lever on the side is not pushed down. If it is, the water valve will be held open and the circulator pump will run continuously. I posted an answer to somebody else's previous question about a system not producing heat. I included a description of how my system works which may help you in understanding how yours works. Good luck.

there's a thermocouple leaving from the pilot to the valve make sure that little copper tube is not grounding to anything metal, it'll become a heatsink... if that doesn't solve your problem return it

Are you sure you wired it correctly? Maybe you mixed up the heating circuit with the cooling circuit? If that's not it, I'd get a new one. Why take a chance?

hello after installing the heater my car sat 12 hours and i had to jump it to get it started so i add a on/off switch to kill the power to the unit when the car isnt running have not had a problem with it sence, other than it doenst put out enought heat

Turn the knob to pilot and press down and hold a while until the thermocouple kicks in, so the pilot will stay lit. Main problem I have had installing these---if the gas has been off a long time, it takes forever to clear the line of air, because the very small hole for the pilot has such a small flow. In that case I loosen a fitting close to the heater and allow a fair amount of gas to flow out --then tighten the fitting. Sounds scary, but so long as you just loosen the fitting , it won't take but a few seconds to tighten the fitting. You can typically tell by the smell when you finally get pure gas flowing.

Thermo-coupling needs to be replaced or look for a reset button near the pilot housing.

Check your dip switch settings are correct, see table 3, pg 5, you might have the heat on dip set (depends on model you are replacing) https://customer.honeywell.com/resources/Techlit/TechLitDocuments/69-0000s/69-2252EF.pdf

Your location(s) depends on the type of heating system you have. Dual zone or single, automatic or manual. It's is best to look on you tube. Mine had 5 actuators and 2 were bad.

You need to make sure you shut it off at the switch. It seems to cycle the heater briefly on an off until the switch is off.

If you are using the remote you might want to check the timer setting. if that is not it I heater has a very good customer service department. here is the website. www.iheaterstore.com/
