How to Choose an RV Thermostat
Choosing your thermostat seems like such a trivial task. But in fact, it’s really important. Your thermostat can make your life a living hell if it’s too complicated or just doesn’t offer everything you need. But, how do you know what you need before you need it? The following section will discuss what exactly to look for when thermostat hunting for your RV.
What Features Does It Have?
Thermostats will offer various features that may or may not be beneficial to you as an RV owner. These features include being able to control your thermostat with an app and having a setback feature in case of a power outage; such features might come in handy to one person, but might be unneeded nonsense to someone else. If you like the look of the features, why not give it a shot?
The warranty of your product is important; if the thermostat that you’re about to order doesn’t have a warranty, do not buy it. Not having a warranty means that you’re simply setting yourself up for failure. Thankfully there aren’t many of those out there. However, keep your eyes peeled.
Of course, the most recent reviews of the product are fairly important to look at before buying. Make sure you have a look at different places like Youtube and Amazon reviews as well as blogs like ours before buying. The various types of thermostat are also an important factor as some are really basic and others fairly advanced and new.

The easy to move slide allows you to set the temperature between 55 to 90 degrees. The small, thin, and basic design allows for this thermostat to blend into any RV.
Analog thermostats are some of the least popular thermostats currently on the market due to their basic design and having a track record as being unreliable. However, if there was one thermostat that broke this stereotype, it would be this one.
It may be simple, but this means that it’s easy to use with the simple analog sliding temperature controls. The various features and modes are what make this product so much better than what stereotypes might have you think. Sometimes simple and basic are what win the gadget race.
Best Dometic RV Thermostat:
Dometic Heat/Cool Analog Thermostat
This is another analog thermostat; it’s without a doubt the best on the Dometic range. The simple design allows you to control the temperature as well as the fan system all from one device.
You can set different fan speeds and adjust the controls as you see fit. The slide controls allow you to set the temperature from 40 - 90 degrees. The small design and generic colors allow for this thermostat to blend into any RV walls.
These analog thermostats are incredibly easy to use and extremely simple; the various features and modes are just as easy to get working. The sliding controls are what make it even easier.
The product blends in well with the background of any RV as it’s a compact product. Unfortunately, these products are known to break and become less effective over time.
Best RV Digital Thermostat:
This thermostat is the best digital/programmable thermostat currently on the market to use in your RV. The easy to use and read 1.5 inch display offers plenty of space to have all the information displayed on one screen.
The product allows for you to accurately set the temperature that you feel most comfortable in with one heat and one cooling system. The product is dual powered, as it operates from a battery and from being hardwired into the RV circuit. These products are a lot more reliable and easy to use, thanks to their superb accuracy.
This product is a lot more modern than the past few thermostats we’ve discussed. The 1.5 inch backlit display will provide you with an accurate reading of everything that’s going on temperature-wise.

Best Coleman RV Thermostat:
Coleman Airxcel 8330-3862
This digital thermostat is part of the Coleman range and is without a doubt the best of that range. This thermostat offers a tiny display that will show you the exact temperature of your RV, which is great for finding that sweet spot or goldilocks zone.
The accuracy is a main attraction for many people; it offers all of the same features, including both heating and cooling modes as well as the speed of the temperature change and whether the fan speed should be high or low.
This product is quite simple, which makes it easy to use; the controls are similar to that of an analog thermostat. However, the only thing that makes it a digital thermostat is the really small screen in the top corner that displays the temperature reading.
However, this temperature display is a huge advantage, despite the size, as this makes your temperature regulation far more accurate. It offers the same basic stuff like the heating and cooling controls. It is a bit unfortunate that this unit doesn’t offer a larger screen for more information.

This thermostat is the best of its range; it offers you a decent-sized digital screen that will display various pieces of information, which makes this product extremely accurate for anyone using it.

This display is probably the biggest advantage of any digital thermostat as it offers accuracy that no analog thermostat could offer. The two heating and cooling systems are the box standard for any thermostat, an advantage nonetheless. Another benefit is that the box blends in pretty well with any background. Our only gripe is that the screen could be bigger for a more clear view of the temperature controls.

This is one of the most advanced thermostats currently on the market. It offers a smart memory which will remember all of your customized settings during a powercut and restart with the same settings; that’s something an analog thermostat can’t do. You’ll find after using a digital thermostat that there’s a lot an analog can’t do.
The temperature regulation is also far better as it will ensure that the temperature meets your expectations. Another huge feature is that it can create four separate climate zones at once. The only downside to using digital is that it might take a little longer to get into the swing of things and learn the various controls.

The thermostat offers the basic heating and cool air along with a self regulating auto fan mode, this works with the help from internal temperature sensors.
The main attraction here is the smart restart function, which will retain the previous custom setting throughout a power outage and then start from where it left off when you gain back power; this feature is a little more advanced. The main problem with this product is the boring design, there’s no flare to the product exterior. However, it does its job quite well.
Types of RV Thermostat
There are four main types of thermostat, all with their own benefits and downsides that you’ll experience when using them. The oldest type of thermostat is the analog, which are rapidly declining in popularity because they just haven’t kept up with the times.
They’re fairly cheap and do their job with average effectiveness. The next would be communicating thermostats, which are the latest in thermostat technology and are usually accompanied by an app that you can control from anywhere in your RV.
The most common thermostat would be the electronic type; these work the same way as their analog cousin. However, they’re far more effective. The programmable thermostat is also a decent variation that is easy to use, all you need to do is set your desired temperature and you’re all set.
How to Install an RV Thermostat
Installing your thermostat can be easy if you know what you’re doing. If you don’t know what you’re doing, well, you’re in luck, as we’ve put together a helpful step by step guide on installing your brand new thermostat.
- Remove the old thermostat and ensure that all power has been turned off. Disconnect the negative cable from the main batteries, take the cover off the thermostat and remove the screws that secure it.
- Disconnect the set of colored wires that are connected to the thermostat using a small screwdriver. It’s important that they don’t make contact with one another at any point during the process.
- Tape off the blue and red wire as they’re not required. The brown wire goes to G, white to W, yellow to Y and green to Rh. The jumper must stay between Rh and Rc.
- Secure the plate back into the wall, pop the new thermostat back into place. Open the panel doors and ensure it’s been switched to off and have two AA batteries installed to power it.
- Reconnect the negative cable to your batteries and turn all the power back in. Give your new thermostat a test.
