17.4 Global operating lock
Operation of the device can be locked to avoid settings
being changed unintended (e.g. through involuntary
touch). The global operating lock will lock the operation on
the device and can only be activated/deactivated via the
WebUI (not via the device itself).
17.5 Mode operating lock
If the mode operating lock is activated the device can be
operated only in the mode that is currently set. The op-
erating mode (auto, manu, holiday or boost) can not be
changed. The mode operating lock can only be activated/
deactivated via the WebUI (not on the device).
You will find further information about operation and
configuration of your HomeMatic Room Thermostat
in connection with the WebUI user interface in the
WebUI manual (available for download at
