When you’re seeking ways to decrease energy bills, getting a smart thermostat is an intelligent idea. These devices pick up on your favorite temperatures and routine and then develop an energy-efficient schedule that fits. 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 out and about. (You might even be able to receive a free smart thermostat depending on rebate programs from your utility supplier in Cedar Rapids.)
Most of the time, installing a smart home thermostat with the support of Ilten's is an uncomplicated task if you have a newer house. But what if your residence is older or doesn’t have the correct wiring? Can you still install a smart thermostat without C wire? We’ll help you figure out the process so you can select the correct thermostat and get energy savings for years to come.
What Is a C Wire and What Does It Do on a Thermostat?
The majority of 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. Without this wire, your new thermostat might cause your heating and cooling system to have malfunctions.
You can ascertain 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 often blue.
- If there are three or four thin multicolored wires, you’re almost there. Check the C wire isn’t tucked within 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 run a smart thermostat with an adaptor designed for high-voltage systems. Or you may be able to use 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 may be a match for your needs.
Nest says its thermostats are created to run on very little power and can typically share it with your heating and cooling system. However, you may need to have a professional like Ilten's add a C wire with the Nest Thermostat E or Nest Learning Thermostat if you’re running into power problems or a battery that’s constantly 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.
