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 carried 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.

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 (
ë
= daytime temperature , ì= reduced set back temperature ) as well as the current boi-
ler 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 weekday.
An activated summer switch-off is represented in the basic display by a sunshade symbol (
À
).
The heating mode symbols
ë
or ìwill be suppressed during an activated summer switch-off.
With acting frost protection function an ice crystal symbol appears in the basic display ( Á).
