When you’re seeking approaches to reduce utility expenses, getting a smart thermostat is a smart move. These devices learn your favorite temperatures and routine and then create an energy-efficient schedule that matches. What’s even better is that you can adjust 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 able to get a free smart thermostat depending on rebate programs from your utility provider in Saint Louis.)
Most of the time, hooking up a smart home thermostat with the support of Morgner Inc. Air Conditioning & Heating is a simple job if you have a more modern house. But what if your residence is older or doesn’t have the proper wiring? Can you still install a smart thermostat without C wire? We’ll help you figure out the process so you can choose the correct thermostat and get energy savings for a long time.
What Is a C Wire and What Does It Do on a Thermostat?
Many programmable thermostats use batteries. When you’re switching to a smart thermostat, you’ll learn 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 determine if you have a C wire by doing the following:
- Cut power to the thermostat at the breaker.
- Take off the thermostat and find the wiring.
- If there are five or six multicolored wires, you have what’s required 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. Make sure the C wire isn’t rolled up 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 operate your new thermostat without one.
- If you have two thick wires, you may be able to run 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 top 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 require minimal power and can frequently share it with your home comfort system. However, you may need to have a professional like Morgner Inc. Air Conditioning & Heating install a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re running into power problems or a battery that’s always drained.
ecobee is compatible with 24-volt systems (ones with three to six thermostat wires) and includes a C wire adaptor. So, you’re taken care of if you don’t have a thermostat C wire.
