When you’re looking for methods to reduce heating and cooling 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 matches. What’s even better is that you can change and keep an eye on your settings from just about 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 supplier in Swanton.)
In most instances, installing a smart home thermostat with the support of Northwest Services is a straightforward job if you have a newer 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 figure out the process so you can choose the ideal thermostat and get energy savings for many years.
What Is a C Wire and What Does It Do on a Thermostat?
Most programmable thermostats run on 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. Without this wire, your new thermostat might cause your heating and cooling system to malfunction.
You can determine if you have a C wire by doing the following:
- Switch off power to the thermostat at the breaker.
- Pull 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 usually blue.
- If there are three or four thin multicolored wires, you’re nearly there. Ensure the C wire isn’t tucked within the wall. If you can’t find one, we may be able to install 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 designed for high-voltage systems. Or you may be able to operate a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring isn’t right and you don’t want to replace it.
Do Nest or ecobee Need a C Wire?
Two of the most popular brands are the Nest smart thermostat and ecobee smart thermostat. If you have two to four wires, these thermostats might work for your needs.
Nest says its thermostats are designed to need minimal power and can frequently share it with your home comfort system. However, you may need to have a professional like Northwest Services 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 connects with 24-volt systems (ones with three to six thermostat wires) and includes a C wire adaptor. So, you’re taken care of if you don’t have a thermostat C wire.
