19.5 Minimum setpoint temperature

A minimum setpoint temperature of 4.5°C is set in the

factory settings. The minimum setpoint temperature (4.5

to 25.0°C) can be adjusted via the WebUI.

19.6 Valve error position

If an empty battery has not been recognized, the radia-

tor thermostat moves back into a „valve error position“.

This avoids, that the set temperature in the room incre-

ases due to a low battery. A valve error position of 15 %

is set in the factory settings. The value can individually

be adjusted (0 to 100 %) via the WebUI.

19.7 Valve offset

If several radiators in one room are operated with a

HomeMatic Radiator Thermostat some radiators may

heat more than others. In certain cases, some radiators

might be hot while others are still cold. To compensate

this, a valve offset can be set for the radiator thermostat

that is mounted on the cold radiator. A valve offset of

0% is set in the factory settings. The value can individu-

ally be adjusted (0 to 100 %) via the WebUI.
