Can I use a thermostat that I buy from Home Depot on an air conditioning for an RV

Asked by Pistol April 27, 2020

Answers

I wish that I could say yes or no but the answer to your question depends upon your system. What I can do is to tell you what to look for to answer the question. The two basic types of thermostats are 24 volt systems and line voltage systems. Line voltage is the same as your lighting and appliances use.Therefore you simply need to determine which your RV uses for the AC. Examine the wiring. Is it thick and heavy copper? Or does your present thermostat have thin wires? Heavy wires would be line voltage. Do not attempt to use the Honeywell or any other thermostat if this is the case.High voltage thermostats are readily available but plan on spending $100 dollars for a good one . The cheaper ones give very poor temperature control.Examine what you have there now .It may indicate 24 volts or 120 or 220 volts.If you have 24 volts, you are good to go with the Honeywell.

Set sliding switch to heat. It may be located at the top or bottom of the thermostat.

Have an old T87F 2873 3 that needs replacing. Only used for A/C. 3 wires. Mercury. Will this...

Yes , this thermostat will work for a/c only. There is no wifi on this thermostat so forget about that problem. Regarding the wiring, there is a jumper making two connections. It tends to cause confusion but requires less wiring. That is why you see two or four wires assuming that it will be used for heating and cooling.Do not remove jumper as it can cause problems. Connect your three wires. Red is for power. Green is for fan. White is for air conditioning.You can place a wire over the jumper if need be.There should be no problem.

FOR YOUR APPLICATION, FOUR WIRES ARE VERY MUCH STANDARD. YOU COULD CONNECT ALL FOUR BUT MAY BE REQUIRED TO CONNECT ONLY THREE SINCE THERE IS A JUMPER ON R FOR THE HEAT AND AC. DO NOT REMOVE THE JUMPER SINCE IT POWERS AC AND HEAT.YOUR LETTERS FOR DIFFERENT FUNCTIONS APPEARS CORRECT AS THEY ARE SUPPOSED TO BE UNIVERSAL. IF YOUR WIRES ARE COLOR CODED, IT SHOULD BE VERY EASY. FOLLOW THE INSTRUCTIONS AND ILLUSTRATION. SUGGESTION- FOR A FEW BUCKS MORE, YOU CAN GET A DIGITAL ONE WHICH WILL GIVE YOU MUCH BETTER TEMPERATURE CONTROL.THEY DO NOT TELL YOU THAT IT HAS AN UNACCESSIBLE LITHIUM BATTERY AND YOU WILL NEED A NEW THERMOSTAT WITHIN 10 YEARS.THE DIGITAL MODEL TAKES ONE AA BATTERY WHICH IS EASILY REACHED. I HAVE HAD ABSOLUTELY NO TROUBLE WITH MINE.

It functions better than digital programmable controls in my opinion. My grip is lack of Quality Control. Although the controller works satisfactory, the settings are not marked (see attached photo). Honeywell has yet to respond to my Case. I recommend it. Just keep in mind to buy a package of peel and stick letters. You'll need them to mark what settings the controller is on.

This thermostat is perfect for installation in where common wire is lacking (no power coming from furnace). Simple design, easy to use, not too sensitive and seems to last for a long time. However, for the HVAC systems coming with common wire, I would recommend installing more advanced type like programmable/smart thermostat given the price being almost the same and rebates from utility companies.

Just what the Doctor ordered...
The unit is simple in design and function, has easy to understand instructions on setting it up, and works flawlessly with a mechanical simplicity that borders on genius. My older thermostat, a fancy computerized model that allowed for network connectivity and web-based controls, lost it's mind - literally. Suddenly my house was getting hot - fast, yet the 'stat said all was well. Go online and it said differently and it refused to let me change it. After many hours of Frankenstein's monster tormenting us, I gave in and went low-tech. My only CON on this unit is it's small size when compared to the larger more elaborate thermostats: wiring with older, thicker wiring like my house means you have to take extra care not to cross anything when installing it. Other than that, I love the simple use and ease of install. I'm never going back to the high-tech stuff like that again.

Simplicity at its best
I had a more complicated thermostat that was a source of frustration. Constanly having to change the program to account for weather variations and the comfort of different family members. I finally replaced it with this gem. A modern take on the simple thermostat that I grew up with. Easy to install and use. Sometimes the simple solutions are the best.
