Yes. We used the same on our old boiler at camp and that was only two wires. Just determine what is your hot wire.

If your air and heating runs off your old thermostat then this should have the same wiring. I did go with this to replace a Coleman, so can't be much help.

Not sure!! Try this #800-468-1502 Or this website http://DIYthermostats.honeywell.comI"m guessing but a 2 wire system would only be for heating OR cooling not both.

It says it does not but I don't know why it wouldn't - I have a gas boiler with baseboard heaters and used this to replace my old thermostat. Just connected the wires and away we went.

This thermostat has a small controller that wires in between the fan and the wiring in your home. As long as that controller can be tucked in out of site behind the mounting shroud, you'll be okay. I believe it will work with most fans out there.

It depends on your existing thermostat. This unit requires 5 wires, with the 5th blue wire requiring 24V. If you have a modern 5 wire thermostat, it should work by hooking it up as you say. If you are currently hooked up to only 4 wires, I suggest getting an HVAC person to help out.

I assume it is electric baseboard heat in which case it is probably controlled by a relay. If you have a voltmeter or multimeter you can check the voltage at the thermostat wire. If it is approximately 24 volts then it will probably work.

You should call the Honeywell help line and ask if this thermostat will work with your particular unit. If not they will suggest the right model.

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

Since the thermostat is z-wave that functionality is handled by the controller software. So the answer its yes depending on the controller software you use with thermostat.

I'm not an expert, but I think you'll be good with that. There are a number of ports for wires that control different functions (heat, air conditioning, fan, power, etc.)When I installed mine, I had the opposite issue. Only two wires from my prior thermostat (simple heat, no fan). I needed to get an extra power source kit with a wire just to power the Venstar. Hope this helps.You could also go to the Venstar site and download the installation instructions prior to buying it just to see if your colored wires match their diagrams.

Yes you should be able to connect the same wires to the same post on the thermostat. mine also came with directions. You should be fine.Good luck

It works just fine, make sure you connect the cables correctly. There is a daily program for heating and A/C, but no weekend programing, so keep that in mind.

I do not believe the TL8230A1003 will work. The thermostat is for 208 or 240 volts which needs four wires to work. Since you have only 2 wires you have 120 volts or you are in Europe with a 2 wire 220 volt system. With only 2 wires the thermostat will not work.

as long as there are 5 wires (color to color) it should work. We have a new travel trailer and the existing thermostat didn't seem to control the air conditioner very well. I replaced the original thermostat with this and it works great, no problems at all.

I just hooked up the wires from my old system to my new one and it worked just fine. My control valves are Orbit, but wiring works the same in every system I know of.

Depends on how many wires , your voltage and wattage. This thermostat uses a two wire setup. It seems like you might have 4 in which case it wouldn't work. Maybe check out the Honeywell site for more specific information and the manual on it.
