Frost/heat protection mode
Ľ
Frost protection will be required if, for example, the room temperature must not fall below
critical values while the window is open. Heat protection can be required where the
temperature rises too much in an environment which is always warm, mainly due to
external influences. In such cases, you can activate the Frost/heat protection operating
mode and prescribe some temperature setpoint of its own for either option, depending on
whether "Heating" or "Cooling" has been selected, to prevent freezing or overheating of the
room.
The activated frost/heat protection can be indicated by the function of a status LED.

Comfort extension (temporary Comfort mode)
You can activate the comfort extension from the night or frost/heat protection mode (not
triggered by the "Window status" object) and use it to adjust the room temperature to a
comfort value for some time if, for example, the room is also 'used' during the night hours.
This mode can exclusively be activated by a presence button or also by the presence
object, respectively. The comfort extension option will be automatically deactivated after a
definable time has elapsed, or by pressing the presence button once more, or by receiving
a presence object value = 0, respectively. You cannot retrigger this extension.
The activated comfort prolongation option can be indicated by the function of a status LED.
i
You can assign an own temperature setpoint to the "Heating" or "Cooling" operating modes
for each operating mode.
Operating mode switchover
You can activate or switch over the operating modes in various ways. Depending on one
another in priority, activation or change-over is possible by…
-
Local control on the room controller display compact module using push button function
(controller operation) and configured operating mode change-over,
-
KNX communication objects separately available for each operating mode or alternatively
through the 1-byte object "Operating mode change-over". In the last case, also through a
controller extension.
The following section describes the individual options for changing over the operating modes in
more detail.
i
The presence message, the window status and the forced object for operating mode
switchover (see following sections) have a higher priority than the change-over of the
operating mode via the controller operation. Therefore, change-overs by evaluating the
appropriate objects have priority.
Change-over of the operating mode using button function
As soon as a button of the TSM is configured to "Controller operating", the "Operating mode
change-over" function can be configured in the button parameters. In this case, a further
definition is required in the ETS configuration as to which operating mode is activated when a
button is pressed. For this purpose, the "comfort", "standby", "night" and "frost/heat protection"
modes are available.
To be able to activate the comfort extension, it is possible to use a presence button either
optionally or in addition. The presence button, just as with the operating mode change-over, is a
