Hello,

Hope you can help and that this isn't too basic of a question. I'm trying to wire a Skytech SKY-1001 TH thermostat to a Jotul GF 400 BV stove. It won't ignite with the receiver set to 'on' or the 'on' button on the remote, and I suspect I'm doing something wrong.

This shows how it's normally wired without the remote (it works fine this way):

This is how I'm attaching the thermostat receiver wires:

I set the rocker switch to thermostat and it doesn't ignite from the receiver or remote. I put the receiver through learn mode and verified that the remote is connecting to it. What is likely to be the problem here? I think I'm probably missing something that would be obvious if I knew a little more.

Thanks
 
Thanks for moving my post to the correct forum. I think the images may have gotten lost in transition.

You have it wired incorrectly, Check the attached manual and look on page16. There is a diagram for the correct connections. You have quite a few wires in the wrong places.

Thanks for looking. The wiring (without the thermostat) was set up by the previous owner of this house or someone he hired. So I am not sure why it is connected this way.

Do you know why the diagram doesn't appear to be for the model/parts I have, even though the manual and my fireplace are both GF 400 BV?

  • The terminal blockin the diagram has four terminals with 2 or 4 wires connected. My fireplace's terminal block has 6 terminals with 5 wires connected.
  • There is a red-black wire in the diagram but not on my fireplace.
 
Your stove has three terminals on the gas valve and three on a separate terminal block. The black wire on the center terminal of the gas valve goes where the white wire is on the separate terminal block and the white wire goes on the center terminal of the gas valve(marked TP), The remote wires go on the center terminal of the separate block and on the bottom terminal with the black wire. Last one there is a red from the thermopile and a black wire on the top terminal of the separate block they need to go to the TH-TP of the gas valve. It sounds confusing but rewire it slowly one wire at a time.

Thanks for the detailed answer. This is very helpful. I'll give it a shot but probably not until this cold snap is over in case I end up making the problem worse. It is a bit of a mystery why the previous owner had this wired in an apparently functional but incorrect way.

Moving the wiring like Tjune54 described so that it matches the diagram in the manual is best in the long run. With that said, I believe that your remote might work just fine with the wiring as is.
If you would like to test this, put the On-Off-Stat switch in the Stat position. Then get a piece of wire or paper clip and touch one end to the yellow wire and the other end to the orange wire.
Assuming that the stove now turns on, connect one of your remote wires to yellow and the other to orange and you should be good to go.

Thanks, great tip. That works. I'll still test rewiring it correctly once winter is over.

That's great, the remote will be a nice addition to your stove.

The main reason to rewire the stove will be to help eliminate any confusion if you need to do any trouble shooting in the future.

When you get around to rewiring it, just make sure you keep the remote connected to the terminal strip where you have it now. If you were to connect it back to the valve where you were first trying it, the stove would turn on and off okay but the spill switch safety would be bypassed possibly creating an unsafe condition.
