can this be used with 4 wire control? No separate wire for heat and cool. Just 28v and common. Fan and heat/cool. SIngle stage propane heat thanks

Not sure however I still have this product just sitting collecting dust. If you want it, it's yours! Free. It didn't work for me and when I called Honeywell they wanted me to get on the roof and explain the circuit board to them! No help what so ever! Got an electrician and he too had problems understanding the wiring. Useless product if you ask me.

If there are two wires coming out of the fan then yes. If there are three then you will need to build a pwm controller. If there are four wires, you will still need to build the controller.

Honeywell has a video showing you how to substitute G wire for C wire. https://www.youtube.com/watch?v=F05lIaNTMB4 Basically, G wire is for operating Fan only mode (no heat / cooling). You loose the ability to use FAN only to power this thing. You have to change wire on the back plate as well as in the A/C-Heater. I'm not very skilled, but I was able to do it, just following the video.

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.

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.

YES, the unit will control 12V fans, no modification is necessary. These controls are used in the HVAC industry and many other 12V applications. I use them to control dual 12V cooling fans to cool transmitter heat sinks and power supplies.

My husband says it only works with propane the way it is set up. Possibly you could run it with natural gas but you would maybe have to change out the regulator or something. Like you would hardwire a gas stove.

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

Well it doesn't work that great on propane nor 12v. Mine doesn't work at all on propane and I plan to return it. It works great on AC. When I did get it to work on propane you still need to supplement with ice.

it should only uses two wire. I have it on a gas fireplace, without blower. if you have more than two wires I don,t if it will work. BOB

Hardware.... I had a contractor run wire from circuit box in my basement to a double stall garage that I keep my summer car in. And it was well worth it. I should have done this several years ago. The heater has to be run on a separate line due to the 5,000 watt...240 volt draw. You can set the thermostat low so that it only comes on once in a while. Amazing how well this heater works in a double stall garage. If you were to heat a single garage the next smaller unit would do the job quite well.

You're on your own for the control cable. You need a light gauge 3-conductor cable (thermostat cable will work), the power supply is only one Amp.

No, you could used it for a propane heater as long as the heater has an electrical igniter you can plug into the thermostate. In fact, you can use it to control vertually anything that is electrical you wanted to control by temperature.... even a warning light that would light when the temperature fell below a certain pre-set temperature.

If you only have 1 hot wire, this switch won't help you. You'll either need to buy a fan with a remote or buy a separate unit and remote for your fan.

it will work on std 8 wire control circuit...pwr, common, fan, 1st stage cool, 2nd stage cool, 1st stage heat, 2nd stg heat and( if you have a HP,) the reversing valve

This is very simple, if you have ever spliced a wire you can do this. There are a few things to know so be sure to watch a tutorial on YouTube first and also realize you will need a thermostat to control the heat level too. The heat would dangerously escalate with this stuff without a proper thermostat. I would suggest using a proportional type thermostat to maintain a smooth target temperature.

Yes, it can. We just upgraded our A/C to a two-stage blower and compressor, and used this same thermostat. However, an additional wire will need to be run from the blower to the thermostat.
