When you’re seeking methods to decrease utility costs, getting a smart thermostat is an intelligent idea. These devices learn your favorite temperatures and routine and then make an energy-efficient schedule that fits. What’s even better is that you can regulate and monitor 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 receive a free smart thermostat depending on rebate programs from your utility company in Greensburg.)
In many instances, adding a smart home thermostat with the assistance of Wallpe Heating & Cooling 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 have a smart thermostat without C wire? We’ll help you figure out the process so you can pick the ideal thermostat and receive 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 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 use this wire, your new thermostat may 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 find 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 often blue.
- If there are three or four thin multicolored wires, you’re almost there. Check the C wire isn’t hidden in the wall. If you can’t find one, we may be able to add 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 run a smart thermostat with an adaptor specifically 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 won’t work and you don’t want to install new wiring.
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 work for your needs.
Nest says its thermostats are made to run on minimal power and can frequently share it with your heating and cooling system. However, you may need to have a professional like Wallpe Heating & Cooling 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 frequently drained.
ecobee connects with 24-volt systems (ones with three to six thermostat wires) and has a C wire adaptor. So, you’re covered if you don’t have a thermostat C wire.
