Hello,

I have a problem with 2 of my 4 KE100.

It seems like they don't close the valve correctly as the radiators are hot 24/7. Both thermostats worked perfectly until a few days ago.

I use the batteries delivered with the KE100 and did not need any adapters for the installation.

The firmware is also up-to-date.

Today I reinstalled, reset and recalibrated both devices but without any luck. The problem still exists.

Last night the temperature was set to 20°C, but the thermostats heated the room to around 26°C!!!. The current outside temperature is 5-10°C

Is there anything else I can try?

Kind regards,

Mel
