When you’re wanting methods to reduce utility bills, getting a smart thermostat is a wise move. These devices learn your favorite temperatures and routine and then make an energy-efficient schedule that matches. What’s even better is that you can regulate and watch your settings from nearly 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 provider in Lodi.)
In most instances, hooking up a smart home thermostat with the help of Tokay is a straightforward process if you have a new house. But what if your house is older or doesn’t have the proper wiring? Can you still have a smart thermostat without C wire? We’ll help you figure out the process so you can pick 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 making the move 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 may cause your heating and cooling system to malfunction.
You can find out if you have a C wire by doing the following:
- Turn off power to the thermostat at the breaker.
- Take off the thermostat and check the wiring.
- If there are five or six multicolored wires, you have what’s required for a smart thermostat. You might be wondering what color is the C wire on a thermostat—and the answer to that is typically blue.
- If there are three or four thin multicolored wires, you’re nearly there. Ensure the C wire isn’t rolled up in the wall. If you can’t find one, we may be able to install 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 install 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 isn’t right 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 could be an option for your home.
Nest says its thermostats are made to require very little power and can typically share it with your HVAC system. However, you may need to have a pro like Tokay 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 frequently drained.
ecobee connects with 24-volt systems (ones with three to six thermostat wires) and has a C wire adaptor. So, you’re good if you don’t have a thermostat C wire.
