ÇChange the set operating mode
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
(Heating OFF and hot water preparation OFF,
only frost protection mode)
F1 Automatic mode 1
(Heating according to timer program 1; HW according to
HW program)
F2 Automatic mode 2

(24 h heating with comfort temperature 1; HW according to
HW program)
CNight mode

program)
FSummer mode

WService (automatic reset after 15 min)
heat generator regulates to HS set temperature =
maximum HS temperature => as soon as a HS
temperature of 65°C is reached, the consumers regulate to
their maximum flow temperature for heat removal (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

Opening the hinged control panel cover automatically
takes you to the display and indicator area.
•The current area "DISPLAY" appears in the display for
a short time (1 clock circuit).
•After the clock circuit the display switches to the
current operating level "INSTALLATION".
•This is displayed for a short time (1 clock circuit) when
you switch to a new area.
ÇSelect the level in which the value to be adjusted or
displayed can be found using the rotary knob.
