5 Best RV Thermostats and How to Use Them

Being comfortable is one of the benefits of camping with an RV. If the weather outside is muggy or bone-chilling, controlling the temperature inside your home on wheels is important. Having a working and accurate RV thermostat can help you stay comfortable and cozy while on the road. 

What Is an RV Thermostat?

An RV thermostat works with the air conditioner and furnace in your RV. You’ll find a variety of options, including analog, digital, and pre-programmable.

How Does an RV Thermostat Work?

An RV thermostat functions much like one in a traditional home. You can adjust the settings directly on it as needed. Typically a single thermostat will control both the cooling and heating functions in your RV. They can also help your unit automatically turn on and off to maintain appropriate temperatures.

Do You Need a Special Type of Thermostat for an RV?

RVs have very different electrical components and capacities than a standard home. The voltage and wiring are all different from what you may have seen. 

So while people can use their electrical skills to install standard thermostats in some cases, it isn’t generally recommended. Thermostats designed for RVs will make for a smooth install and yield the best results.

Types of RV Thermostats

Not all RV thermostats are the same. Once you’ve decided you need to swap out your thermostat, you’ll need to determine what style fits your situation the best. Here are a few options to keep in mind as you begin your search. 


An analog RV thermostat is the most basic one you can install but a dependable option. If you don’t need something fancy and want to keep it budget-friendly, an analog option is often a great choice. With an analog unit, you can change the settings with a slider. 

Analog units work by using a heat-sensitive metal that bends when it changes temperatures. This makes contact with a switch to turn on heating and cooling. These thermostats do not need any electrical power to operate.

Digital thermostats allow you to quickly and accurately see your settings at a glance. You don’t have to second-guess what temperature you’ve set. They also allow you to change your settings with confidence and set precise numbers easily. 

Digital thermostats use electrical temperature sensors and need power to operate. Usually power is provided on the wires to the furnace.

Consider whether you want a digital or an analog thermostat.


A programmable RV thermostat allows you to choose when you want your settings to go into effect. This enables you to have your unit kick on at a predetermined time, so you’ll have a comfortable RV after a day out exploring. A programmable unit can save you money as you won’t heat or cool your RV when you aren’t there. 

Smart Thermostats

Smart thermostats can change based on your preferences and external conditions. This saves on electricity costs as it learns how and when to adjust and work effectively. A smart thermostat allows you to set your desired temperature and forget about it. They also have smartphone apps, so you can monitor or change your RV’s temperature remotely.

How Do You Know if Your RV Thermostat Is Bad?

If you find that the indoor temperature doesn’t seem to line up with what your thermostat shows, you likely have a faulty one. If your air conditioner and furnace don’t respond to your thermostat, you will want to troubleshoot to confirm if the problem is with your thermostat or your heating and cooling units. 

Pro Tip: One way to heat your RV in colder months is to use an RV furnace. Since there’s a lot to learn about furnaces, we put together The Beginner’s Guide to RV Furnaces.

When my factory installed Coleman thermostat failed last winter, I decided to advance the thermostat into the 21st century. Surprisingly, the upgrade was not more expensive and was easy to install myself. I went with the new Micro-Air EasyTouch. Their website helped me identify which model to purchase. After using it now through all seasons (air conditioning and heating) it controlled both perfectly. And it handled both zones (seperate A/C) without a problem. Plus, we are very concerned about the tempertaure inside the Motorhome, even when away from it, as our dog may be left inside. With this Micro-Air Thermostat, I can connect remotely, using my cell phone app, and see what the temperture inside the motorhome as from anywhere. I can make adjustments if necessary. I highly reccomend this Micro-Air Thermostat.

I purchased an RV thermostat from Dometic when the factory one in my RV started going out. It replaced my old one perfectly and has been functioning very well for a month now. I love that this thermostat connects to both the air conditioner and the furnace. As you probably know, some models only link to the furnace, which isn’t ideal for someone like me who values convenience.
