Install a Ring Thermostat

Installing a Ring Thermostat in an Older Home

When connecting a smart thermostat to an older home that only has two wires, an adapter is necessary to ensure the thermostat receives the proper amount of power. Without this adapter, the smart thermostat can be damaged due to excessive voltage. Smart thermostats rely on common wire, known as C wire, to power the unit. This eliminates the need for batteries and can provide much more reliable performance than an older wiring system. 

Do You Need a Contractor to Install a Smart Thermostat

If you're looking to upgrade your thermostat, you'll want to hire a contractor. They will be able to install a proper C wire and determine if an adapter is needed since some older systems may not be compatible with the new thermostat. Don't stress about trying to do it yourself; a professional installation can ensure that everything is taken care of correctly.
