ÇOperating mode selection
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.
The following operating modes are available for selection:
iStandby / OFF

WService (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.
