Usually if this is a residential heater you are talking about....
r=red which is your 24 volt power and sometimes a jumper will go to rh if you have that on yours
w= white and is for heat some units have w2 still is heat
y= yellow and this is the cooling circuit
g=green and is the fan circuit
some units have a "c" terminal which is common most of the time they use blue but i have seen black or brown used before.
hope this helps you out.....please vote

Electric Wall heater programmable thermostat


First of all most home thermostats operate on 24volts. If you want to have one that directly turns the 240 volt power on and off you need to get a special 240V line voltage thermostat. How many wires come out of your heater? Most 240v circuits have three wires. A white wire for the common and two black or black red wires that are +120 volts and negative 120 volts. That's why a 240 volt plug has 3 prongs instead of two. If you look at the wiring diagram that comes with the thermostat it should give you an idea of how to hook the wires up. In your particular case though, I think I would try making friends with an electrician.

Thermostat Line Voltage How to Install or Replace


You either have a new line voltage thermostat or have to replace your old line voltage thermostat. In either case the process is much the same.

1286363.jpg

  1. Make sure that all power is turned off at the breaker panel. Most heaters that use a line voltage thermostat usually use 240v current so the breaker will either be a double pole breaker or you will need to turn off two single pole breakers to kill all of the power.
  2. Check to see which wires are hooked to the breakers. In most cases it will be the red and black wires, but I have seen many times that the white and black wires were used. Often there is no red available when the white is used.
  3. Take out the two screws that hold the thermostat to the junction box. When you get the thermostat out make a note of which wires go to the heater (load) and which wires are coming from the breakers. (line)
  4. If you have a single pole thermostat installed one of the sets of wires may be wired straight through the box or have the line and load wires connected directly in the box. With a double pole t-stat you will have both sets of wires running through the t-stat.
  5. Remove the old thermostat and wire the new t-stat in the circuit with the load wires hooked to the load or heater and the line wires hooked to the wires coming from the breaker. Make sure to get a very good tight connection as resistance loads will heat up quickly if good contact is not made. This poor connection can and will start fires.
  6. Turn the power on and check the heater for heat output.
  7. Turn the power back off and carefully screw the thermostat to the junction box securely. Then you can reapply the power to the circuit.

Now you are up and running with a new line voltage thermostat installed.

Have electri heater. put in new honeywell thermastat programmable. did not hook up jumper wire like it said. now ac will not come on. if hook jumper wire, then both ac and heater comes on. whats the...


From end to end you have to put the red to red (24vac in), white to white (Furnace on wire), Black to common (24vac common), green to green (Fan On), yellow to yellow (AC On) and the jumper link back on. Also when you hook up the AC the two wires go, one on common (black) and the other on Yellow.
Looks like somehow you are picking up the AC & heater at the same time. If you need more info e-mail me at rspiak1@cogeco.ca

Hello there
It sound alright but You should draw out a wiring diagram on paper first before you tackle the job that way you know you're doing it right.

Good luck Dickson

I need a diagram on abaseboard heater


The common usually goes staight to the unit, and the other wire, goes through the thermostat, and the ground wire hooks directly to the chasis of the heater.
If it is a 120 Volt, the white wire should be the common, and the black runs through the thermostat.
If it is a 220 Volt, it doesn't matter which wire goes through the thermostat.

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.

Want to hook wall thermost to Rinnai propane space heater


If you are just going for heat only just connect the t_stat at these setting red wire R white wire to W green wire to G

Now the heater you can go to the gas valve or if it has a circuit board go to Red to R and white to W Green to G. Green is optional you just need two wires hooked up. You will see on top of the gas valve three connections the ones marked th are the ones you need.
