Part1: Operation

For initial start-up or the "level Installation" please read the installation manual.

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:

i Standby/OFF

(operating flap closed)

(Heating OFF and hot water preparation OFF, only frost protection mode) Exception: see F15 Function page 55

F1 AUTOMATIC 1 (Automatic mode 1)

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

Operating elements

Ç Change the set operating mode

F2 AUTOMATIC 2 (Automatic mode 2)

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

h HEATING (Day mode)

(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)

Part1: Operation Operation in normal mode

W Service (automatic reset after 15 min)

Boiler regulated at Boiler temperature = max. boiler temperature= see page 33 ; 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.

Operation in normal mode Part1: Operation

Display in normal operation

! 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

E Display of the active heating program for the first heating circuit (here: 6:00 to 08:00 hrs. and 16:00 to 22:00 hrs.)

F Status display: H internal burner 1 relay ON;

D heating mode; F hot water preparation

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

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

=> Heating according to timer program 2).

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 cur-

rent operating level "INSTALLATION".

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

you switch to a new area.
