What steps can I take to prolong the lifetime of the batteries for my Smart Thermostat or Smart Radiator Thermostat?

The Smart Thermostat is designed to run on 3x LR03 (AAA) and the Smart Radiator Thermostat on 2x LR6 (AA) alkaline batteries.

For long battery life please observe the following points:

  • Always replace all batteries at the same time, eg. do not mix old batteries with new batteries in one device.
  • Do not mix batteries of different types, eg. Alkaline with NiMH
  • Only buy alkaline batteries, eg. LR03 (AAA) for use in your Smart Thermostat and LR6 (AA) for use in your Smart Radiator Thermostats
  • Do not use zinc-carbon batteries. These are labelled as R03 and R6 type batteries and are often called "HEAVY DUTY” but are not suited for use in tado° products.

You will receive an email when the batteries in your Smart Thermostat or Smart Radiator Thermostat start to run low. Typically you will have four weeks from the notification email to replace the batteries.

Replacing the batteries before depletion is important in order to make sure your devices stay connected.
