Turn the knob to select the operating mode required. The
operating mode selected is indicated by a symbol at the
bottom of the display. It takes effect when the setting is not
changed for 5 s.

Part 1: Operation Operation in normal mode
W Service (automatic reset after 15 min)
Boiler regulated at Boiler temperature = max. boiler
temperature= see page 34 ; when the boiler temperature
has reached 65°C, the consumers are regulated to their
flow temperature to dissipate heat (cooling function).
! The cooling function must be explicitly enabled in
the consumer circuits by means of a set value.
Effect of the operating mode
The operating mode set here affects the boiler regulation
and the integrated heating circuits of the controller.
Each heating circuit can be assigned a separate operating
mode from the one set by means of the "operating mode"
parameter in the user level of the corresponding heating
circuit.
When the "i = Standby/OFF", and "F = Summer mode"
operating modes are set, they have a reducing effect on
system controllers with respect to all heating circuits and
consumer circuits in the entire system.
! For mixer controllers the reduction of operating
mode is only effective for internal heating circuits.

! Due to the tolerances of sensors, deviations of
+/- 2K (2°C) are normal between various
temperature displays. Temperatures which change
rapidly can have higher deviations for short periods
due to the different time-related behaviour of various
sensors.
! The display of the current heating program applies
to the device's first heating circuit.
In case of having two heating circuits the display can
be set to the 2nd circuit
