How to Reset Thermostat

The thermostat that controls the temperature of your home can malfunction, and resetting it can fix many issues, especially those to do with the functioning of the digital display. I’ve done a bunch of research into how to fix thermostats so today I’ll share how to reset every kind of thermostat there is.

First turn off your thermostat, and then disconnect the power by turning it off at the fusebox, wait for 10 seconds and then turn the fuse back on. After that, turn the thermostat back on. The off button can be on the digital display or located on the sides of the thermostat.

How to Reset Thermostat

There are various ways to perform a normal reset and a factory reset on a thermostat due to the wide range of brands of thermostats. But, in general there is one broad method that will reset any thermostat regardless of the brand. Here’s how to do it.

You should disconnect the power, and reconnect it again. Generally, it’s recommended to turn the thermostat off first. Then disconnect the power at the power to it at the fusebox, also called a switchboard. Turn the fuse back on, and then turn your thermostat back on again.

As you may know, the fuse box is the main control point for power to the different wall outlets around your home. A thermostat is generally wired directly into the mains, and doesn’t have a wall outlet you can switch on and off. Therefore, the only option is to turn it off at the fuse box. If you don’t know how to do it, it’s very likely someone in your household will know. Otherwise, here’s a really good video on Youtube that explains what a fusebox is and shows how to use a fuse box.
