How To Change Hive Thermostat Battery. Switch the boiler off at the isolation switch/fuse spur (this should be located near your hive receiver next to your boiler). Using lithium or rechargeable batteries may damage the device.
All you do is plug it into your socket, plug your appliance into the thermostat, set the required temperature and that’s it. If you are upgrading from hive active heating™ to hive active heating™ 2 you will need to take the batteries out of your old thermostat when prompted. A red battery symbol means your batteries need to be replaced with four new aa batteries.
This afternoon, i got another email from hive to say the batteries need changing!
If you wish to keep the old thermostat please let the engineer know. When replacing the batteries in your leak sensor, please use 2 x aa alkaline batteries. This thermostat works with an electric radiator to give you more control over how it heats the room. If your thermostat battery dies somehow or you forgot to change the thermostat battery on time then, your thermostat will go blank and it affects your cooling and heating system.
