What Is a Dometic RV Thermostat?
RV thermostats are devices that control the temperature inside your vehicle while you’re away. It can be helpful if your RV is too cold or hot, but it could also be dangerous and result in costly repairs. There are a few things you need to know before buying one.
First, what type of thermostat do you need? A manual or automatic? Manuals work like regular thermostats in your house – you set the temperature, and it stays that way until you change it. A mechanical model will adjust the temperature based on the current weather conditions. Which one you choose is up to you – either will work fine.
Next, what size thermostat does your RV require? Most RVs come with either 1/2 or 3/4 horsepower thermostats, so be sure to pick the right one if you’re not sure. The next question is, where should the thermostat be located in the RV? Most people put them near the air conditioner unit, but there’s no wrong answer here. Just make sure you can reach it without getting out of bed!
Now that we’ve covered what a Dometic RV thermostat is and what type of device it is let’s take a look at how to wire it up! All Dometic models use either three-pin or four-pin wiring, so make sure to get the correct connector for your rig – often, there’s a label on the connector or inside the RV itself. Once you have the right connector, plug it into the wall, and your RV’s thermostat is ready!
How Does a Dometic RV Thermostat Work?
The Dometic RV thermostat is a device that controls the heat and air conditioning in an RV. The thermostat is installed in the engine compartment and connects to the wiring system through the factory harness.
When you turn on the ignition, the thermostat starts to warm up the engine block. As long as you keep the engine running, the thermostat will maintain a set temperature by controlling how much energy is supplied to the furnace. The engine cools down quickly when you stop driving, and so does the thermostat. The next time you start your RV, it will begin to be cold because there is not enough energy stored in the battery to reach operating temperature.
Dometic includes a built-in timer that resets itself after approximately 20 minutes of inactivity to prevent this from happening. If your RV has been parked for longer than 20 minutes, it is best to reconnect your battery before starting your RV.
