Can a house thermostat be used in an RV?

No you cannot use a typical residential thermostat in an RV. The reason is that most of them are designed to use 24 volt AC power, and RVs have no such power source. You can use a thermostat that is battery-powered and that is designed for “millivolt” control systems.

Instead, an RV thermostat runs off 12 volts. In the end, this difference in voltage is the main difference between a regular thermostat and an RV thermostat. But there are other smaller differences between the two that are worth mentioning.

Subsequently, question is, can I replace my thermostat myself? An experienced DIY-er can install most programmable thermostats and some smart thermostats. Don’t forget to turn off the breaker to the HVAC equipment! If the job requires more than just a replacement, a certified HVAC professional can ensure proper installation, as well as operation of your heating and cooling system.
