I’ve had a pellet stove in my upstate house for about eight years. Right now I have it connected to a Honeywell programmable thermostat. It has two wires, a red and a white. I have them connected to the R and O/B terminals. When I got this stat, I had hoped that I could program it to come on on Friday afternoons so the house would be warming up when we get there. It never worked out right but now have hopes again.
I also got a 24v transformer/relay. The transformer/relay has one black and one white 120v input wires and on black, one red and one brown output wires. Here are the wiring instructions;
I should have everything I need and someone on stove forum set gave me this wiring diagram but I still don’t know how to wire it’
That diagram is for a separate transformer and relay. Can anyone explain how I wire this up. I appreciate your help.
You have to check out the instructions on the stove versus the thermostat. For example, you may need to have a different kind of thermostat, one that takes its power directly from a 110/ 220 live feed versus one that feeds off of the stove unit itself.
In my old home, our boiler had power wired into the unit and the thermostat simple controlled a switch. The switch and thermostat needed very little power and had a converter before running out to the stat. When I put on an additional room and added electric baseboard heating, a regular thermostat didn’t work since you the bb heating was either on or off. It required a different kind of stat, one that broke the entire electric feed to the units. My guess is that your pellet stove is closer to the latter and not the former.
Yes, the pellet stove does not power the thermostat. It originally came with a simple mercury thermostat When I stitched to the programmable thermostat, the stat had a back up AA battery so I used that to power the stat. It lasted at least three years before I had to change it. The new wifi stat has a battery but the instructions say that it will not power the stat. The transformer/relay is to power the thermostat. I just don’t know how to wire it.
Can’t help on this issue directly, but I can give you a vector to check out…
Diychatroom.com (link) is a good place to get reliable & solid help on DIY stuff of all kinds. Post this question in the “HVAC” room/forum there (with the pics - those will be helpful), and I’m confident you’ll get the right answer. It’s a well-moderated site, and the regular posters there know what they are doing.
At this point, I’d advise you to get a pro todo the install… it wont be too expensive while the other option could burn down your house.
It won’t burn down the house. If I wire it wrong, it just won’t work and could damage the stove. I got that wiring from Hearth.com. I think I’ll check back over there again.

Thanks, I forgot all about Diychatroom. I was already a member over there. I asked yesterday and they had the answer this morning. It’s going to be a nice warm winter at the Sweeney house!
The pellet stove doesn’t supply power to the thermostat. I had to wire in a transformer and then wire it to the stat. I didn’t understand how to wire it, but someone on the DIYchatroom sight posted a simple wiring diagram. That’s it, I can now raise or lower the pellet stove temp from anywhere I want. Nice!
It works, Yippee! It’s going to be nice and warm when the Sweeney’s get to their mountain house this winter!
Glad to hear it! Yeah, as someone pretty new to the world of DIY, that site has been a godsend for me… It’s awesome to have one go-to site that can very reliably & quickly address just about any home-realted project imaginable.
Lurking on that site and the LR here accounts for ~99% of my time online
This is absolutely Great. The thermostat gives me indoor and outdoor temperature. Yesterday when I left Long Island at noon, it was 42 outside and 51 inside. Using my iPhone, I turned the pellet stove on and raised the temp to 66. When I got here at 3, it was 62 degrees inside. Yippee! When it gets colder this winter, I’ll start the pellet stove a lot earlier and get the house nice and toasty once I shovel my way in.
I built this house over 20 years ago with a wood stove for heat. Sometimes in winter, I’d get here and it would be in the thirties inside but never below freezing even when it was zero outside. I’d fire up the stove and it would take all night to warm the house. Almost ten years ago I got the pellet stove and a programmable thermostat. It was like living in luxury, to warm up the house all I had to do was push a button. About four years ago, we got high speed internet here. Now with the wifi thermostat, it’s like I’m living in the Future.
You’ve got to do this. It’s 29 degrees and snowing outside and I just walked in to a house that’s 59 inside. It’s now 1:51 pm and I started the pellet stove at 8 am from over 100 miles away. I’ve got the wood fire going now in the airtight fireplace and the pellet stove will go off in a few hours, then come back on over night. The best part, even better than walking into a warm house, is when I wake up at 4 am, I can reach over to my iPhone, turn up the heat, and go back to sleep for another hour. It’s like being George Jetson!
