So my question is this is electric heat? it sounds it so next question is it 120 or 240 volt. but you will have a black and a white wire from your electric panel feeding the line side of the thermostat then another wire loading from the t-stat to the electric heat. i hope this helps.

Without knowing the brand and model - it's hard to be sure - but if it is it a built-in electric baseboard heater; most are designed to be powered at either end. The typical manner is power is brought to the thermostat. Power from the switched output of the thermostat is brought to either end of the heater and connected to the wires from the heater. The opposite end of the heater should have the heater wires connected together. They may also be used to bring power to a second heater that is to be controlled by the same thermostat - usually only if it is very close by though. As long as there are no other wires at this end of the heater - simply connect them together - otherwise the heater will not work. You should do this work with power OFF. Most heaters that are built in are 240 volts and can kill you if you're not paying attention!

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: my honeywell ct87K thermostat will not turn the heater on

On your thermostat - R is the power in terminal. Y is the cooling out. W is the heating out. (G is fan out). It does not matter which wire goes to R, the other should go to W - if no heat with a call, the thermostat is bad.

SOURCE: Heating and Cooling Thermostat - can't get the wires right

You most likely do not have AC.
Red to R (24volts), White to W(heat).

Black(usually common), Orange(usually reversing valve for a heat pump, could be anything you want it to be as long as you wire it on both ends correctly), and Green (usually FAN) were buried, so they were never used.

SOURCE: I'm replacing a non-hydronic electric baseboard

Hello. The red and the black are the hot wires. Therefore, connect one of your conductors to the red and the other conductor to the black. Use wirenuts. The bare ground wire should be solidly attached to the new unit's green wire using a wire nut.

There are so many questions. WHAT IS THE MODEL number of the unit that you are wiring The thermostat and the source voltage are two different things. What voltage are you wiring this to?

Replace three wire thermostat with four wire thermostat


From the two red and two black wires (and the specs in the pdf), your new thermostat sounds like it's designed to directly control the line voltage (120 or 240) to the heater. That's the usual way baseboard heaters are controlled.

Could your wires be red, black, and (old, yellowed) white, the standard colors in a 3-wire power cable? Just the red and black should be enough to control a 120-volt heater so I don't understand what the white would have been used for. If it were my heater I'd take off the cover(s) -- with the power off, of course -- and find out what those wires actually connect to.

Heating and Cooling Thermostat - can't get the wires right


Depending on if you have gas or oil heat the connections would be slightly different, but if you were only using the red, white, and black before, this should work. Red to Rc with jumper to Rh (or vise versa..) White to white, and Black to your Y terminal. Your Rc and Rh terminals are your 24 v supply, Yellow is connected to your outdoor unit, and W is the common for the heat, and G is for you high speed fan. Hope this helps

Electric baseboard heater


You need a meter, it will be hard without this! If you have 220v in the wall, then think of it like this; each wire is 120v. Test to each other, you get 220v. The thermostat is a double pole, you said. So think of it like this, its an adjustable temperature controlled switch that lets electricity through at the temp. you set it at. If you have 120v from one wire connected to one end of the element, and the other 120v connected to the other end of the element, then it will work. DO NOT CONNECT THE 120V TOGETHER. IT MUST GO THROUGH THE ELEMENT FIRST. The thermostat should be between the power from the wall and the element, to control the temperature.

How to wire 1 plf 1504d heater


I have the solution, finally after looking for 2 days.

First off, I couldn't quite put it all together based on what I was reading. I finally tracked down the Fahrenheat web site (www.fahrenheatpro.com). And called tech support (800) 452-4179.

To wire 2 BB units to 1 tstat.

1. Use #14 wire for 0-12 amps, #12 wire for 12.1 to 16 amps and #10 wire for 16.1 to 24 amps.

2. I have a 12/2 wire going from the tstat to BB#1 and another 12/2 wire going from BB1 to BB2.

3. Onthe left side of the heater, you will have 2 sets of black wires tied together with a nut (on right side it's 2 sets of Black/Red wires). You can use either side of the heater. For the purpose of explaining this, lets use the left side, 2 sets of black wires.

4. Undo one of the sets of black wires (it doesn't matter witch), the other set will be left alone.

5. Take the black wire coming from the tstat and tie it into one of the black wires from the heater and the black wire going to the second BB unit. So you will have those 3 wires tied together with a nut at the 1st BB unit.

6. Take the white wire coming from the tstat and tie it into the other black wire from the heater and the white wire going to the other BB heater. Again, you will have 3 wire tied together here.

7. At the second BB unit, tie the black wire coming from the 1st unit to one of the black wires in one of those 2 sets of black wires. Again, only undo 1 set of wires at the 2nd unit, leave the other one alone. Tie the white wire coming from the 1st unit to the other black wire.

8. Make sure ground wire in grounded at the tstat and at both BB units.

Hope this helps...... If I was less clear than I hoped, call tech support and they will walk you thru it....

Kevin.

Cadet wall mount and thermostat


your wiring is all wrong. for a 240 heater a 20/20 tandem breaker will not work with a 240 heater. you need a 20 amp two pole breaker. the two wires at the heater need to be connected to the line. you probably have two black wires at the heater. one connects to the white romex which should be taped black, and the other romex black connects to the other black wire. at the panel one white goes to one side of the breaker and the black to the other. the bare ground goes to the neutral bar.
