How to replace new furnace thermostat
All you need to do is attach the red wire to the R terminal and the black wire to the C terminal. When it comes time to turn on your furnace, flip the switch. And when you want the heat turned off, flip it back again. It’s that easy!
Furnace thermostats are thermometers that measure the temperature of the air inside your home. If you want a more accurate reading of how cool your home is running, you can change the settings on your thermostat and add a sensor to it.
The most basic way is to swap out the thermostat with one that has an integral sensor already installed.
To do this, you’ll need an electrical screwdriver, voltage tester, wire connector or pliers, electrical tape and wire strippers/cutters/crimpers. You’ll also need a different type of thermostat than what you have now – so make sure to read the packaging before making any purchases!
The best way to determine how to hot wire a furnace thermostat is to consult a qualified technician.
