When you’re looking for methods to lower utility costs, getting a smart thermostat is an intelligent decision. These devices pick up on your favorite temperatures and routine and then make an energy-efficient schedule to match. What’s even better is that you can change and keep an eye on your settings from almost anywhere with your phone, whether you’re lying in bed or on the go. (You might even be able to receive a free smart thermostat depending on rebate programs from your utility supplier in Central Point.)
In many instances, hooking up a smart home thermostat with the assistance of Titan Heating & Air Conditioning is a straightforward process if you have a more modern house. But what if your house is older or doesn’t have the correct wiring? Can you still add a smart thermostat without C wire? We’ll help you demystify the process so you can select the right thermostat and get energy savings for many years.
What Is a C Wire and What Does It Do on a Thermostat?
Many programmable thermostats need batteries. When you’re making the move to a smart thermostat, you’ll find that many require 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:
- Turn off power to the thermostat at the breaker.
- Take off the thermostat and look at the wiring.
- If there are five or six multicolored wires, you have what you need for a smart thermostat. You might be pondering 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 nearly there. Check the C wire isn’t rolled up inside the wall. If you can’t find one, we may be able to install 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 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 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 might work for your home.
Nest says its thermostats are made to need not a lot of power and can typically share it with your HVAC system. However, you may need to have a professional like Titan Heating & Air Conditioning 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 works with 24-volt systems (ones with three to six thermostat wires) and comes with a C wire adaptor. So, you’re good if you don’t have a thermostat C wire.
