ON / OFF OFF
The optimized start and stop time can be based on either room or
outdoor temperature.
ON: Optimization based on room temperature, if
measured.
OFF: Optimization based on outdoor
temperature. Use this setting if the room
temperature is not measured.

Circuit Setting range Factory setting
I OFF / 1 ... 20 K OFF
The desired ow temperature in heating circuit I can be
inuenced by an external reference.
OFF: The desired ow temperature in circuit I
is not inuenced by any other controller
(slave).
1 ... 20:
The desired ow temperature is increased
by the set value (line 17), if the demand of a
slave is higher.

Example:
If a slave controller demands a higher temperature
than that of the master controller (T
ow.ref(I)
),
the temperature of the master will be increased
accordingly (T
ow.ref(II)
) + the setting (line 17).
The function of line 17 can compensate for heat losses between
master and slave controlled systems.
