When you’re wanting methods to reduce utility bills, getting a smart thermostat is a wise idea. These devices pick up on your favorite temperatures and routine and then create an energy-efficient schedule that fits. What’s even better is that you can change and monitor your settings from nearly anywhere with your phone, whether you’re lying in bed or on the go. (You might even be able to receive a free smart thermostat depending on rebate programs from your utility company in Front Royal.)
In many instances, installing a smart home thermostat with the assistance of Dave's Diversified Services is a straightforward task if you have a more modern house. But what if your home is older or doesn’t have the right wiring? Can you still install a smart thermostat without C wire? We’ll help you navigate the process so you can select the proper thermostat and get energy savings for many years.
What Is a C Wire and What Does It Do on a Thermostat?
The majority of programmable thermostats use batteries. When you’re upgrading to a smart thermostat, you’ll find that many need a C wire, or common wire, for power. If you don’t use this wire, your new thermostat could cause your heating and cooling system to have glitches.
You can determine 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’s required for a smart thermostat. You might be wondering 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 almost there. Make sure the C wire isn’t tucked within the wall. If you can’t find one, we may be able to add 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 use a smart thermostat with an adaptor just 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 install 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 could be a fit for you.
Nest says its thermostats are created to require not a lot of power and can often share it with your heating and cooling system. However, you may need to have a specialist like Dave's Diversified Services put in a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re experiencing power problems or a battery that’s always drained.
ecobee connects 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.
