The center-positioned rotary-push button and the labeled keys guarantee a simple and easy operation.

It is however recommended to read this manual attentively to be informed about the repeating steps.

– Each value in the display appears flashing and can be modified with the rotary-push button.

A flashing display is appropriately marked in this manual.

Turn to the right (+): Increase values

Turn to the left (-): Decrease values

– Press once: Acceptance of the selected and indicated value, store.

– Keep pressed: Entry into the programming level (level selection),

The last operation step will be stored automatically after approx. 60 seconds if it was not stored by

means of the rotary-push button.

Turn: select parameters, change values

Press once: confirm, store

Start-up

In case of initiation of the plant or after every power failure a display test of the large display is car-

ried out with automatic error diagnosis. At that all available segments and symbols will be displayed.

Language selection

In case of first initiation the desired language can be chosen after the display test. The languages

DE, GB, FR, IT, NL, ES, PT, HU, CZ, PL, RO, RU, TR, S, N can be selected.

Note: This display appears after every restart on day of first initiation until midnight. After that

the language can only be changed in the level SYSTEM - parameter LANGUAGE.

Device identification

After the display test and/or the language selection the device identification momentary appears

with device type, interface and the corresponding number of software version.

Basic display

Provided that there is not any error message, the basic display indicates the date, time, heating

mode (

= daytime temperature ,

= reduced set back temperature ) as well as the current

boiler temperature or, if released, the room temperature. Response time program. The cursor

below (

) indicates the current operating mode (see function of operating modes). The upper

time bar shows the heating periods and the corresponding operating times of the current week-

day.

An activated summer switch-off is represented in the basic display by a sunshade symbol (

The heating mode symbols

will be suppressed during an activated summer switch-off.

With acting frost protection function an ice crystal symbol appears in the basic display (

Manual hot water loading

To activate manual hot water loading out-

door of operation times the button

§§

has

to be pressed for about 3 seconds. This

turns on hot water preparation at any time

for a period which may to be adjusted with

the rotary-push button between 0 ...240

minutes. Pushing the rotary-push button

activates loading. Afterwards the controller

returns to program operation.

At adjustment 0.0 the loading is independent

of any time period. The tank will be loaded

up to the set DHW-temperature value once.

Short-time operational modes

Frequently used operating modes such as

PARTY or ABSENT or reloading the hot

water tank during set back mode can be sel-

ected quickly according to the left scheme.

Direct automatic mode

Pressing button

¢¢

for approx. 3 seconds

activates the automatic mode via timer in-

evitably. Functions and setting range see

This button regulates the heating characte-

ristics of each heating circuit in relation to the

outside temperature.

The adjustment is dependent of the plant installation and

shows the relation between outside temperature and heat

generator temperature and/or flow temperature.

The slope sets the change of the respective supply tempe-

rature, if the outside temperature changes for 1 K.

The standard programs do not get lost by overwriting with individual

programs. Individual programs however are cancelled at a later call

of the corresponding standard programs and have to be set up

again. For this purpose individual turn-on and turn-off times should

always be noted (see Operating Times - table for individual operating

times and programs).
