When you’re seeking ways to decrease heating and cooling costs, getting a smart thermostat is a wise idea. These devices adjust to your favorite temperatures and routine and then make an energy-efficient schedule that matches. What’s even better is that you can adjust and watch your settings from almost anywhere with your phone, whether you’re relaxing in bed or out and about. (You might even be able to get a free smart thermostat depending on rebate programs from your utility provider in Troy.)
In most instances, installing a smart home thermostat with the support of Edington Heating & Cooling Inc is a straightforward task if you have a newer house. But what if your home 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 pick the right thermostat and enjoy energy savings for a long time.
What Is a C Wire and What Does It Do on a Thermostat?
Many programmable thermostats use batteries. When you’re upgrading to a smart thermostat, you’ll learn that many have to have 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 malfunction.
You can ascertain if you have a C wire by doing the following:
- Cut power to the thermostat at the breaker.
- Pull off the thermostat and find the wiring.
- If there are five or six multicolored wires, you have what’s needed for a smart thermostat. You might be pondering what color is the C wire on a thermostat—and the answer to that is typically blue.
- If there are three or four thin multicolored wires, you’re almost there. Make sure the C wire isn’t tucked inside the wall. If you can’t find one, we may be able to install one for you or you may be able to run your new thermostat without one.
- If you have two thick wires, you may be able to use a smart thermostat with an adaptor specifically 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 isn’t right and you don’t want to install new wiring.
Do Nest or ecobee Need a C Wire?
Two of the best-selling brands are the Nest smart thermostat and ecobee smart thermostat. If you have two to four wires, these thermostats might be a fit for your home.
Nest says its thermostats are made to require minimal power and can often share it with your home comfort system. However, you may need to have a professional like Edington Heating & Cooling Inc install a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re having power problems or a battery that’s frequently drained.
ecobee is compatible with 24-volt systems (ones with three to six thermostat wires) and has a C wire adaptor. So, you’re taken care of if you don’t have a thermostat C wire.
