Operation in normal mode

Ç Operating 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:

(operating flap closed)



Ç Change the set operating mode

i Standby / OFF

(Heating OFF and hot water preparation OFF, only frost protection mode)

F1 AUTOMATIC 1 (Automatic mode 1)

(Heating according to timer program 1; DHW according to DHW program)

F2 AUTOMATIC 2 (Automatic mode 2)

(Heating according to timer program 2; DHW according to DHW program)

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

C REDUCING (Night mode)

(24 h heating with reduced temperature; HW according to program)

F SUMMER (Summer mode)

(Heating OFF, HW according to HW program)

Part 1: Operation Operation in normal mode

W Service (automatic reset after 15 min)

heat generator regulated to heat generator set temperature = max. heat generator temperature= see page 35 ; when the heat generator 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 the parameter B-HEAT SINK.

Effect of the operating mode

The operating mode set here affects the HS 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.

If the "i = Standby/OFF", and "F = Summer mode" operating modes are set at the boiler controller, these settings have a reducing effect on all heating circuits / consumer circuits that are present in the entire system.

! For mixing controller only on these heating circuits.

heating circuit (here: 6:00 to 08:00 hrs and 16:00 to 22:00 hrs)

! Due to the tolerances of sensors, deviations of

+/- 2 K (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

F Status display: H Burner ON; D heating mode;

G Mode selector switch, the display applies to all heat-

ing circuits for which a separate operating mode has been selected via the "MODE" set value (here: F

a short time (1 clock circuit).

 After the clock circuit the display switches to the cur-

rent operating level "INSTALLATION".

 This is displayed for a short time (1 clock circuit) when

you switch to a new area.
