How to charge Nest Thermostat?
Usually, all the Nest thermostats, including both E and N-type, charge their battery automatically from the main power supply to the HVAC. However, you’ll have to charge your device yourself if there’s any problem with this connection or a power cut.
Here are the troubleshooting steps to charge your Nest thermostat:
Restarting your thermostat
The first and the most important step to charge your thermostat is to restart it. This will aid in resolving all the problems within your system, most importantly the battery issue. So, here are the steps to restart your thermostat:
- Press the thermostat ring for around 10 secs until the screen goes off.
- Now, release the ring back.
- Lastly, turn the thermostat back by pressing and releasing the ring. This will turn on your device and thus will complete the first step.
Charging the thermostat manually
The next step is to charge your nest thermostat manually using a USB cable. However, note that to do so, first, you need to remove the display and then plug it into the USB. You may connect the cable to either the wall charger or your computer.
After doing so, you’ll see red blinking light, indicating the connection is accurate. Further, put back the display once the charging is complete. You may now check if the problem is resolved. If not, then the main issue is behind the HVAC system and not your thermostat.
Check the connection of the wires
If charging the thermostat manually didn’t resolve your problem, there may be some defect with the wires. They may either be loose, burned, or have some internal error. If any such problem is present, try to fix them using tape.
Try resetting your thermostat
If the steps mentioned above didn’t help you, the problem is behind your system, not the thermostat or HVAC system. In such a situation, resetting your system is the only option. Here are the steps to reset your thermostat:
- Head to the Quick View menu by pressing the thermostat ring.
- Now select Settings.
- Next, turn the ring to Reset.
- Lastly, select the option All Settings. Note this will restore the default factory settings of your thermostat, fixing all the problems.
Note if none of the above steps resolve your problem, then you’ll need to contact the HVAC expert for their assistance in tackling this issue.
