When you’re looking for ways to lower utility bills, getting a smart thermostat is an intelligent idea. These devices pick up on your favorite temperatures and routine and then develop an energy-efficient schedule that fits. What’s even better is that you can adjust and keep an eye on your settings from just about anywhere with your phone, whether you’re relaxing in bed or away from home. (You might even be able to get a free smart thermostat depending on rebate programs from your utility supplier in Mount Hope.)
Most of the time, hooking up a smart home thermostat with the support of Appalachian Heating is a simple process if you have a more modern house. But what if your residence is older or doesn’t have the correct wiring? Can you still have a smart thermostat without C wire? We’ll help you figure out the process so you can select the correct thermostat and enjoy energy savings for years to come.
What Is a C Wire and What Does It Do on a Thermostat?
Most programmable thermostats use batteries. When you’re making the move to a smart thermostat, you’ll find that many need a C wire, or common wire, for power. If you don’t have this wire, your new thermostat could cause your heating and cooling system to have malfunctions.
You can ascertain if you have a C wire by doing the following:
- Turn off power to the thermostat at the breaker.
- Take off the thermostat and look at the wiring.
- If there are five or six multicolored wires, you have what you need for a smart thermostat. You might be thinking what color is the C wire on a thermostat—and the answer to that is often blue.
- If there are three or four thin multicolored wires, you’re nearly there. Make sure the C wire isn’t rolled up within the wall. If you can’t find one, we may be able to put in one for you or you may be able to use your new thermostat without one.
- If you have two thick wires, you may be able to run a smart thermostat with an adaptor designed for high-voltage systems. Or you may be able to use a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring is incompatible and you don’t want to put in new wiring.
Do Nest or ecobee Need a C Wire?
Two of the top brands are the Nest smart thermostat and ecobee smart thermostat. If you have two to four wires, these thermostats might be an option for you.
Nest says its thermostats are made to require not a lot of power and can frequently share it with your heating and cooling system. However, you may need to have a pro like Appalachian Heating put in a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re running into power problems or a battery that’s constantly drained.
ecobee is compatible with 24-volt systems (ones with three to six thermostat wires) and comes with a C wire adaptor. So, you’re taken care of if you don’t have a thermostat C wire.
