When you’re seeking methods to lower utility expenses, getting a smart thermostat is a wise move. These devices learn your favorite temperatures and routine and then create an energy-efficient schedule to match. What’s even better is that you can regulate and monitor your settings from almost anywhere with your phone, whether you’re lying in bed or away from home. (You might even be eligible for a free smart thermostat depending on rebate programs from your utility supplier in Rio Grande Valley.)
In most instances, installing a smart home thermostat with the help of Cytech Heating & Cooling L.C. is an uncomplicated task if you have a newer house. But what if your house is older or doesn’t have the right wiring? Can you still add a smart thermostat without C wire? We’ll help you demystify the process so you can select the proper 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 run on batteries. When you’re making the move to a smart thermostat, you’ll learn that many require a C wire, or common wire, for power. Without this wire, your new thermostat could cause your heating and cooling system to malfunction.
You can find out if you have a C wire by doing the following:
- Switch off 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 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 typically blue.
- If there are three or four thin multicolored wires, you’re nearly there. Ensure the C wire isn’t rolled up in the wall. If you can’t find one, we may be able to add 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 install a smart thermostat with an adaptor designed for high-voltage systems. Or you may be able to install a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring won’t work 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 might be a match for your home.
Nest says its thermostats are made to require not a lot of power and can typically share it with your home comfort system. However, you may need to have a specialist like Cytech Heating & Cooling L.C. add a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re experiencing 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 good if you don’t have a thermostat C wire.
