SOURCE: Williams wall non-elec gas heater. Black copper wire tagged thermostat?

First make sure this is a heater set up for a remote mounted thermostat. If so, the gas valve has 3 screws labeled TH (thermostat) and TP (thermopile) that's the flame sensor with 2 wires coming off it, I don't know where the goofy name comes from. there will be one screw that has both, usually the top one. Wire accordingly. The new valves have a solenoid on the bottom. this connects to the high temp. sensor up top. It has 2 wires on it, one connects to the thermostat wire, the other goes to the screw with TH and TP. Or you can skip it and connect the wire from the back of the valve to the Th and TP screw. Make sure the thermostat wires aren't pinched somewhere, thus eliminating the thermostats control.

SOURCE: Wiring diagram for a Dayton thermostat

Contact Dayton on the internet for this problem. The diagram should be available on their site. Or they will give you a number for customer care. They can give you step-by-step instructions. I am a technician and this is what I would do as their are millions of wiring diagrams. Many are noy up to date.

SOURCE: Properly installed electric baseboard heater won't work.

I am an electrician. You must measure the voltage across the black and red wires. Measuring each wire to the neutral will not cut it. If both your red and black wire are on the same phase the heater will not work.

To double check your wiring, measure the voltage across the two screws feeding your subpanel, they should be 240v or 208v depending on your power company. Then do the same at the breaker feeding your thermostat. Again it should read 240v.

If you have no potential across the screws it is possible that you installed an incorrect breaker. Not all breakers with two screws on them are 240v breakers. There is what is called a twin or split breaker that has two screws that are on the same phase. These are for wiring two 110v circuits, when you run out of spaces in the panel.

Double check everything. This is a relatively easy circuit to wire, even for homeowners. If the heater does not work them something is wrong so do not leave the circuit energized.

SOURCE: Replaced mercury thermostat w/Honeywell CT87K - doesn't work!

You need a specific thermostat for a Wall Furnace it is a Millivolt Thermostat and not a 24v standard thermostat....usually it will work anyway however if the powerpile (generator produces millivolts from the pilot light) is weak it may not be producing enough...or the Pilot light may be dirty and lazy...won't produce enough millivolts ...or you can have bad or dirty contacts or connections....or a combination of any of the above.....a 24v Thermostat and particularly a non-mercury thermostat has too much resistance in it for a millivolt system....as your Wall Furnace (other than the fan) runs on less than 1 volt

How do I replace the thermostat on a Teledyne Laars EPC 250?


First, for your information, Jandy, is now the new owner of Teledyne Laars.
So, their parts will work, and are an exact fit for any Teledyne Laars product.

What did you have prior to the new thermostat control board, that you purchased? Was it just a mechanical thermostat?

I can try to assist you. But I would need more information, and more time to look at the wiring diagram.
please upload them here, and one of us here, would be glad to assist.

you can also email me at
p s m helps at g mail

Black wire from top of heater connects to #1 top left screw.
Red wire from top connects to #3 top right screw.
Blue wire from upper element connects to #4 middle screw on right side
Red wire from lower element connects to #4 middle screw on right side
Yellow wire from upper element connects to #2 lower left screw
Black wire from lower thermostat connects to #4 lower right screw
Upper element: Yellow and Blue wires connect to either screw
Lower element: Red wire from top connects to either screw
Lower thermostat: Black wire from top connects to top screw

Floor heater won't light


At the gas valve on the furnace, jump the two connections where the thermostat wires attach to, I think TH and TP may be marked on terminals. If it lights, you have bad wire(s) going to thermostat. If it still refuses to light, you may be looking at a new gas valve.

Line voltage Tstat installation Dayton D-F79 elctric shop heater


If I understand your post correctly....You state that you are hooking up a 240v heater and towards the end you speak of removing jumpers...W2 terminals..ect. It sounds to me your trying to us a 24v low voltage thermostat instead of a Line voltage thermostat.That's what I'd take a look at.
