2 or 3 wire thermostate?

I believe it is just 2-wire. We use it to control our pellet stove. Works great.

This is a two wire thermostat. This is not programmable. It is just your down to earth basic thermostat. Not for use with central air. If you need one for a/c you need another model.

I used 2 wire harness from some speaker wire i have, hooked up too the W & R terminals and it works fine. furnace is a Coleman York i switched to propane for shop use.

This Thermostat takes 4 wires. Compare the wiring design of your current thermostat with the Honeywell. I had to run the 4th wire for my system which was the C wire.

Hello Joe, this thermostat is for Heat and Cooling system. it control both heater and air conditioner and I have 4 wires to the unit. I'm not sure it would work with only 2 wire controller.

If there are 2 leads, it should work. You will need to install a GIF prior to the thermostat.

Yes, they both handle 4 or 5 wire 24volt heating / cooling systems. Just be careful you use the correct wiring diagram for your system. Some have one transformer and others have 2. Use a small piece of masking tape and mark each wire you remove from the old thermostat. The mounting holes are probably different so you might need new anchors for the new thermostat. I did.

Good luck.There's also a contact phone number listed: 856-234-8803. Just a side note; why don't you have your landlord replace it? Yes, they both handle 4 or 5 wire 24volt heating / cooling systems.

No. A sensor can only be linked to one thermostat. On the other hand, multiple sensors can be linked to one thermostat.

For me there was one already installed to control a fan. The existing one went bad and locked into full power so I replaced it. There was three wires from my fireplace. One is power that is looped with a thermostat and the other is a neutral. Should be simple swap out, resolder the wires and it's ready to go.

It needs two wires for 24volts. Just installed one at my home. It's a great thermostat and the install is not difficult, just give yourself an afternoon to make it look nice. Make sure that the control unit can be mounted at least two feet from the thermostat.

i dont think so !this thermostat creats its own currant milovolt through the pilot thermocoupler !. and it only uses 2 wires, it sounds like you need a outside power source for the third wire

its a switching device. i believe it will work for any two wire heat only set up provided that it falls within your amperage specifications. i replaced my atwwood thermostat with this device and it works well. It comes with a back plate to cover any size opening.

Not sure whether or not they can. Can you provide more details as to what your trying to accomplish by having 2 thermostats.

Not sure since I use a forced air furnace (no a/c). Check your existing thermostat - I only hooked up 3 wires and it works great!

Theoretically yes. However unless you understand electrical wiring etc I would leave it to a license electrician. Since it has a thermostatic control built into the switch I really don't see the advantage of another thermostat.

PFL2004 requires 8.3amps, 2=16.6amps, three 25.1amps. so, thermostat and wiring rated more than 25.1 amps answer is yes, however, I doubt that is the case. 14 gauge wire is rated 15amps, 12 gauge 20 amps, 10 gauge 30 amps, is your "one line" 10 gauge wire? probably not. Moreover, question is puzzling, why three on one thermostat, heating a barn?

What they didn't say was that there is a 4 wire and 3 wire thermostat. That said, just turn the thermostat down to shut off the heat.

If you want to use the automatic setting, you'll need to run wires for the outside temperature sensor. Most of the rest of the wires should be pretty similar though.

No. 4 wires are required for a heat only setup and 5 are required for heating and cooling. There are kits that allow a 4 wire setup for heating and cooling, but you lose independent fan control with those kits. The unit needs power from the furnace from 2 wires - a 24 volt hot wire and a common aka "c" wire and 2 wires for the heat and fan signals in a heat only application. The 5th wire is for the cooling signal.
