When you’re seeking ways to decrease utility expenses, getting a smart thermostat is a wise decision. These devices pick up on your favorite temperatures and routine and then develop an energy-efficient schedule to match. What’s even better is that you can change and keep an eye on your settings from nearly anywhere with your phone, whether you’re lying in bed or on the go. (You might even be eligible for a free smart thermostat depending on rebate programs from your utility provider in Rio Grande Valley.)
In most instances, hooking up a smart home thermostat with the assistance of Cytech Heating & Cooling L.C. is a straightforward process if you have a new house. But what if your residence is older or doesn’t have the right wiring? Can you still have a smart thermostat without C wire? We’ll help you demystify the process so you can choose the proper thermostat and get energy savings for years to come.
What Is a C Wire and What Does It Do on a Thermostat?
Most programmable thermostats use batteries. When you’re switching to a smart thermostat, you’ll find that many have to have a C wire, or common wire, for power. If you don’t have this wire, your new thermostat might 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.
- Remove the thermostat and check the wiring.
- If there are five or six multicolored wires, you have what you need 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 close. Make sure 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 operate your new thermostat without one.
- If you have two thick wires, you may be able to install a smart thermostat with an adaptor just 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 best-selling brands are the Nest smart thermostat and ecobee smart thermostat. If you have two to four wires, these thermostats could be an option for you.
Nest says its thermostats are made to run on very little power and can often share it with your home comfort system. However, you may need to have a specialist like Cytech Heating & Cooling L.C. put in a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re having power problems or a battery that’s always drained.
ecobee works 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.
