RV Thermostat Wiring Diagram: A Comprehensive Guide

If you are an RV owner, you understand the importance of having a reliable thermostat. A thermostat is a device that regulates the temperature inside your RV. It is an essential component of your RV’s heating and cooling system.

In this article, we will discuss RV thermostat wiring diagrams. You will see the different types of thermostats and how to wire them correctly. Additionally, we will cover frequently asked questions about RV thermostats.

Types of RV Thermostats

Before we talk about wiring diagrams, let’s explore the different types of RV thermostats. There are two main types of thermostats used in RVs: analog and digital thermostats.

Analog Thermostats

Analog thermostats are the older type of thermostats. They use a dial or slider to regulate the temperature inside your RV. These thermostats are relatively simple to use and maintain. However, they are less accurate than digital thermostats.

When installing or upgrading your RV thermostat, make sure to verify the voltage. Analog thermostats use 12 volts DC, while digital thermostats use either 12 volts DC or 24 volts AC.

Digital Thermostats

Digital thermostats are the newer type of thermostats. They use a digital display to regulate the temperature inside your RV. These thermostats are more accurate than analog thermostats. Additionally, they often come with advanced features like programmable temperature settings.

When upgrading to a digital thermostat, make sure to purchase one compatible with your RV’s wiring. Also, pay attention to the wiring instructions supplied with the thermostat. Generally, digital thermostats require more wiring connections than analog thermostats.

RV Thermostat Wiring Diagram

Now that we have covered the different types of thermostats let us dive into the wiring diagrams. There are several steps to follow when wiring an RV thermostat. Ensure that you follow them carefully to avoid any mistakes. Here is a step-by-step guide on how to wire an RV thermostat.

Step 1:

Turn off the power to your RV’s heating and cooling system. You can do this by turning off the power at the breaker box or disconnecting the batteries. Safety first, always.

Step 2:

Remove your old thermostat. The process will depend on the type of thermostat and the RV model you have. Most thermostats have screws or clips that hold them in place. Unscrew or unclip, whichever works for you, and remove the thermostat from the wall.

Step 3:

Label the wires coming from the wall. You can use masking tape or stickers to label the wires. It is essential to label them to avoid mixing them up when installing the new thermostat.

Step 4:

Install the new thermostat base on the wall. Use the screws or clips to secure the base. Ensure that the base is level to avoid any imbalance when installing the thermostat.

Step 5:

Connect the wires to the new thermostat. Follow the wiring diagram supplied with the thermostat. Generally, there will be five wires: red, white, green, yellow, and blue. Match the wires from the wall to the correct connection points on the new thermostat.

Step 6:

Attach the thermostat to the base. The method will depend on the thermostat model you have. Most thermostats slide onto the base and clip or snap in place. Carefully read the installation instructions supplied with your thermostat.

Step 7:

Turn the power back on to the heating and cooling system. Test the thermostat to ensure it is working correctly. Set the temperature to your desired level and make sure that the heating or cooling system turns on and off as required.
