changing of the operating mode (e. g.
several times a day) during running
operation can adversely affect the life of
the device as the read-only memory
(EEPROM) used has been designed for
less frequent write access events only.
Frost/heat protection
Automatic frost protection
via window status
Here it is possible to determine how the
room temperature regulator switches
into the frost/heat protection.
With "automatic frost protection": the
automatic frost protection is activated.
Depending on the room temperature this
allows an automatic switch-over into the
frost protection mode.
With "Via window status": switch-over
into the frost/heat protection takes place
via the "window status" object.

0.2 K / min.
0.3 K / min.
0.4 K / min.
0.5 K / min.
0.6 K / min.
This parameter determines the decrease
temperature by which the room
temperature has to decrease within one
minute in order for the controller to
switch into the frost protection mode.
The "OFF" setting will deactivate the
frost protection automatic.

The length of the automatic frost
protection is defined here. After the
preset time has elapsed, the controller
will return to the operating mode which
was set before frost protection. Re-
triggering will not be possible.

Automatic frost protection"!
Window status delay

0
...255
This parameter defines the delay time
for the window status. After the
parameterised time has elapsed after
the window is opened the window status
will be changed and thus the frost/heat
protection mode activated. Such delay
can make sense if short ventilation of
the room by opening the window is not
supposed to change the operating
mode.
