When you’re looking for methods to reduce energy bills, getting a smart thermostat is an intelligent move. These devices adjust to your favorite temperatures and routine and then develop an energy-efficient schedule that fits. What’s even better is that you can regulate and watch your settings from just about 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 supplier in Derby.)
In many instances, hooking up a smart home thermostat with the support of Giordanos Heating and Air Conditioning is a straightforward job if you have a newer 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 figure out the process so you can select the recommended thermostat and receive energy savings for a long time.
What Is a C Wire and What Does It Do on a Thermostat?
Most programmable thermostats use batteries. When you’re making the move to a smart thermostat, you’ll learn that many need a C wire, or common wire, for power. If you don’t use this wire, your new thermostat could cause your heating and cooling system to have glitches.
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 usually blue.
- If there are three or four thin multicolored wires, you’re close. Check the C wire isn’t hidden inside the wall. If you can’t find one, we may be able to add 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 operate a battery-powered smart thermostat, like the Lux Geo Wi-Fi Thermostat, if your wiring is incompatible and you don’t want to put in new wiring.
Do Nest or ecobee Need a C Wire?
Two of the most popular brands are the Nest smart thermostat and ecobee smart thermostat. If you have two to four wires, these thermostats may be a fit for your home.
Nest says its thermostats are created to run on not a lot of power and can typically share it with your home comfort system. However, you may need to have a professional like Giordanos Heating and Air Conditioning put in a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re running into 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 taken care of if you don’t have a thermostat C wire.
