A closed switch means that the brine pump is active.
Contact for activation of "temporary lux"
An external switch function can be connected to F1155
for activation of the hot water function "temporary lux".
The switch must be potential-free and connected to the
selected input (menu 5.4, see page 51) on terminal block
X6 on the input board (AA3).
"temporary lux" is activated for the time that the contact
is connected.
Contact for activation of "economy"
An external switch function can be connected to F1155
to activate comfort mode "economy" for hot water op-
eration. The switch must be potential-free and connected

Comfort mode "economy" is activated for the time that
the contact is connected.
Contact for activation of "external adjustment"
An external contact function can be connected to F1155
to change the supply temperature and the room temper-
ature.
When the switch is closed the temperature changes in
°C (if the room sensor is connected and activated). If a
room sensor is not connected or activated, the desired
change of "temperature" (heating curve offset) with the
number of steps selected is set. The value is adjustable
between -10 and +10.
