My old thermostats has an extra copper wire for ground. This thermostat comes with only 2 wires. Can I just leave the ground wire out?

This unit has no place to connect a ground so you have to just leave it out. Unless it's an old metal box which you would connect the ground, but the thermostat itself has/needs no ground. I've used this in two different homes.

Connect your grounding wire to an acceptable ground or to another grounding wire.This thermostat is inserted in between two hot wires.

You can. I did, but you then lose the added protection of having the unit grounded. No big deal for me. Mine works great!

I'm not an electrician but the thermostat will work fine unattached to the ground wire. If there is a ground on the box you may want to connect it to that.

No, I just wired it to the thermostat that was wired directly to the breaker. Just like your furnace thermostat.

You must supply power to the thermostat. In my case, more wires ran between the furnace and the thermostat than were actually used on either end. I just had to figure out where to connect one of the extra wires on the furnace side, to supply the power to the thermostat.

It can be connected with anywhere from 2 to six wires depending on your system. I used only two because I don't have air conditioning and I use a battery instead of AC to power the thermostat. It's a good, versatile thermostat that's easy to install with your installation manual, and easy to program. Took me about 5 minutes to install, and I've never installed one before.

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.

No. The copper wire is not the ground. This cable does not have a separate ground wire attached (not that its necessary or even useful). A standard coax such as this one has 2 lines, the center copper wire "signal" and the outer shield "ground". The shield serves as the ground line for the signal, but this is not the same ground you need if you are talking about antenna installation. Antenna's need a separate heavy gauge short straight run to an actual ground (lightning protection). In my opinion, coax wires with the extra ground attached to the side are useless.

I just used the wires supplied from the unit itself. Simple 3 wire connection. There are no additional connections or additional wire needed. Simple instructions will show you where to connect them. Should you have any issues, please let me know. You will be very happy with this unit. I am. Ron, Mesa, AZPS remember to shut off A/C unit breaker before attempting to install.

No Eric - you need to but a plug in thermostat be careful of your electrical system - I burned out the circuit using this heater and had to re wire that room and put it on it's own breaker - my house is 100 yrs old and still had some hidden nob & tube wiring which I feel contributed to the problem - ever since the new wire is in no problems

If the existing thermostat just closes a low voltage circuit it should work. That's most two wire thermostats. The only other considerations are the minimum run time and the low & high set point. You can adjust the temp spread on this unit using jumpers inside it.

First of all you don't have to activate this sensors. Wires from thermostat should have connection to this sensors. You connect the sensors first and then thermostat. Hope this helps. Let me know if you have question.

It doesn't use a regular thermostat wire use the actual wire that powers it I'm guessing u could change the thermostat

My timer came with three wires, one that acted like the input wire, one that acted like the output wire, and the third is to be connected to the ground. My guess is if you do not have a ground in your house wiring, then do not connect the ground to anything. that seems to be fairly typical for older homes. I've had a couple of houses that were older and there were no ground wires, either. The ground wire is usually uninsulated.

Yes. The thermostat is on a small circuit board -- easily reachable. A pair of wires comes from the solar panel -- cut that. Another pair goes to the fan. Cut that pair and connect to solar pair. Run free. Sam

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.

"C" wire ? you mean common, or ground wire ? No. 2 wires in from furnace/boiler is all I connected.

I never actually used it. I purchased it because I needed to relocate my thermostat, but was put off by the rerouting of the wires. After some thought, I figured how to reroute the wires, so I returned it before I installed it.

Assuming that you are replacing an existing thermostat, replace the wires in the exact same sequence as the old. I always make wires before I remove them. If it is a new installation refer to the furnace wiring instructions. If you are a novice electrician, call a professional installer. It costs money ,but you will get heat and cooling that works.
