Domestic RV Thermostat Wiring Diagram

Thermostats were one of the best inventions in the world, especially for people living in regions with extreme temperatures. And if you are someone who lives in an RV and travels around to such regions, you are definitely going to need a thermostat in that RV.

With most brands being pretty good for usage in homes, Domestic is one that produces thermostats specifically for RVs. You are probably already thinking about getting one but might be contemplating.

Maybe seeing the domestic RV thermostat wiring diagram might help you decide and get a better idea of the device. Well, here we are with just that and more things you might need to know about an RV thermostat.

By the end of this article, you will be well informed about how RV thermostats work, how you can set them up (in what configuration), and which thermostats would be the best choice for an RV, particularly from the brand Domestic.

So if that sounds interesting to you, let’s go forward with this article!

How Does an RV Thermostat Work?

A thermostat is basically able to essentially control the temperature of an entire room or even the whole house. An RV thermostat is very similar but is meant for use in an RV only.

You can set the thermostat for cooling or heating depending on the weather of the region you are in currently, and the device will optimize the temperature of your motor home accordingly.

  • RV Cooling

All you have to do is literally tell the thermostat not to let the temperature get beyond a certain point to keep the RV nice and cool. Thermostats by Domestic comes with this feature, and it regulates the temperature as you need it to be.

Let’s say that you want it to remain roughly 72 degrees and not more than that. The thermostat will provide air and cooling based on that command, providing you the comfort you need.

  • RV Heating

Sometimes, especially during winter, the need for heating inside an RV increases. The setting for heating up is the same as cooling. You input a set point, and the thermostat will handle the rest.

If the temperature is cold, the thermostat turns on the furnace and heats up the RV. In case it gets too hot, it automatically turns on the fan as well.

Different Configurations in RV Thermostat

You can set up the thermostat in an RV in two different ways. Either set up the RV air conditioner thermostat onto the ceiling unit along with the furnace thermostat on the wall or just set them both up on the wall.

  • RV AC Thermostat on the RV Ceiling + Furnace Thermostat

If your RV has a ceiling unit, otherwise known as plenum or ADB (air distribution box), you might have to set up the AC thermostat there. In such a case, you have to install the furnace onto the wall. Thus having the temperature control from two, possibly different, directions.

RV AC Thermostat

The wiring and stuff are different for the ceiling unit thermostats and wall mount thermostats. So only use this setup if your RV has a ceiling unit and get the right thermostat for it.

Also, this one applies to the setups that involve two different thermostats for heating and cooling. With Domestic, you do not have to deal with all that hassle. Since you are going for a Domestic thermostat, move to the next section for the ideal setup.

  • RV AC and Furnace Thermostat on the Wall

It is the ideal setup if your thermostat can control both heating and cooling at the same time (no, not simultaneously). Such thermostats are better off being installed onto the wall mount.

The ones by Domestic are of this kind, and seeing the wiring diagram that we have given below should give you a clearer idea of how these thermostats should be and how they are wired.

Below is the wiring diagram of the Domestic RV thermostat for you to get a clearer understanding of how the device needs to be wired onto your RV.

One of the main differences between regular thermostats and RV thermostats is the power supply and voltage.

As you can see, RV thermostats use only 12 V of power, whereas regular thermostats need 24 V. It is quite impossible to supply 24 V to an RV thermostat, as it is all only coming from a battery.

Besides, the wiring is a little different too. If you are good with wires and know what you are doing, this should help you understand better. But if that is not the case, we suggest getting a professional electrician to help you set up your RV thermostat. Learn about Nest Thermostat E Wiring Diagram.
