When you’re wanting approaches to reduce heating and cooling costs, getting a smart thermostat is a smart decision. These devices adjust to your favorite temperatures and routine and then develop 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 eligible for a free smart thermostat depending on rebate programs from your utility supplier in Auburn and Opelika.)
In most instances, installing a smart home thermostat with the support of Farnell Mechanical, Inc. is a simple task if you have a new house. But what if your residence is older or doesn’t have the proper wiring? Can you still add a smart thermostat without C wire? We’ll help you figure out the process so you can select the right thermostat and get energy savings for years to come.
What Is a C Wire and What Does It Do on a Thermostat?
The majority of programmable thermostats need 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 may cause your heating and cooling system to have glitches.
You can ascertain if you have a C wire by doing the following:
- Switch off power to the thermostat at the breaker.
- Remove the thermostat and find 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 typically blue.
- If there are three or four thin multicolored wires, you’re almost there. Ensure the C wire isn’t hidden inside 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 run 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 is incompatible and you don’t want to replace it.
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 an option for your home.
Nest says its thermostats are designed to require very little power and can often share it with your heating and cooling system. However, you may need to have a pro like Farnell Mechanical, 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 constantly 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.
