Removing the existing thermostat
To ensure that the radiator valve is accessible for the installation of the Home Control Radiator Thermostat,
remove the old thermostat or (for a new radiator) the protective cap.
Depending on the type, thermostats are removed differently; some are simply unscrewed, while
others have to be detached using a standard tool. For more information, refer to the respective
manufacturer's documentation.
Inserting the batteries
Always keep batteries away from open flame and high temperatures. Avoid direct
sunlight and heat radiation!
Always remove all batteries from battery-operated devices that are only in storage
and are not in use. Old batteries can leak and damage the device!
Do not use rechargeable batteries!
When inserting the batteries, ensure that the polarity is correct. Using the batteries
incorrectly can damage the device!
The Home Control Radiator Thermostat uses commercially available AA alkaline batteries. For in-
formation on replacing the battery, please refer to the Home Control online help.
