I Want a Smart Thermostat but Don’t Have a C Wire – What Do I Do?
When you’re seeking methods to decrease utility expenses, installing a smart thermostat is an intelligent decision. These devices adjust to the temperatures you like and routine and then develop an energy-efficient schedule that matches. What’s even better is that you can change and monitor your settings from just about anywhere with your phone, whether you’re relaxing in bed or on the go. (You might even be able to receive a free smart thermostat depending on rebate programs from your utility supplier in St. Cloud.)
In many instances, adding a smart home thermostat with the help of Osceola Air, LLC is a simple 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 add a smart thermostat without C wire? We’ll help you navigate the process so you can pick the right thermostat and get energy savings for a long time.
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 discover 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:
- Cut 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 usually blue.
- If there are three or four thin multicolored wires, you’re almost there. Make sure the C wire isn’t hidden in 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 install 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 won’t work 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 a match for you.
Nest says its thermostats are designed to consume 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 Osceola Air, LLC add 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 works 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.
