The Nest thermostat is one of the best-selling smart thermostats you can get. And for good reason. It learns your temperature preferences and develops an energy-efficient schedule to match. And through geofencing with your phone, the Nest Learning Thermostat and Nest E are aware of when you’re at your house or away and can adjust temperatures to help you save even more.
The Nest is compatible with a wide range of 24-volt heating and cooling systems, but it’s always a good idea to use the Nest thermostat compatibility checker before getting one. Don’t forget to contact your energy supplier for valuable rebates, since you might be able to get a Nest for free or close to it.
Once you’ve made sure it’s compatible, you can either install it without help or contact a HVAC professional like Farnell Heating & Air Conditioning Inc. If you’re putting it in yourself, you’ll spot a terminal for the C-wire, or common wire. This wire is just used for powering your thermostat. If your house or HVAC system is older, you might not have one of these wires. In the majority of cases, Nest says this isn’t an issue as the thermostat can draw ample power from other heating and cooling wires.
Sometimes, your heating and cooling system might need that C-wire. And here’s why.
Why Your Nest Keeps Losing Power and Other Malfunctions
The Google Nest Thermostat is better than aging programmable thermostats that use a combination of wiring and AA batteries for power. It has a rechargeable lithium-ion battery and wiring to connect to Wi-Fi, power its digital display and run your heating and cooling system.
8 Common Nest Thermostat Malfunctions
If it can’t draw ample power, Nest says you could encounter some of these problems:
- Poor battery life.
- Thermostat motion sensing won’t work.
- Your thermostat occasionally disconnects from Wi-Fi.
- Your system unexpectedly turns on or off, or won’t stop running.
- Your system is producing weird noises, such as chattering, stuttering, clicking or thumping.
- Heating or cooling is short cycling, or repeatedly turning on and off in a short period of time.
- There is a delay message on your Nest thermostat’s screen, like “heating is delayed for 2:30 minutes.”
- The system fan is continuously working, won’t switch on or turns off and on frequently in a short period of time.
You might think something is suspect with your heating and cooling system, but if you just got the Nest, we suggest you start with your thermostat right away. This is especially true if the weather is mild, and you haven’t been using your heat or air conditioning much.
