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.
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 (
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).

for a period which may to be adjusted with
the rotary pushbutton between 0 ...240
minutes. Pushing the rotary pushbutton
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.

This parameter specifies the heating delimiting value regarding
the average resp. current outdoor temperature and puts the
heating plant automatically out of service as soon as the outdoor temperature exceeds the set heating delimiting value.
During summer switch-off the pump of the heating circuit is
activated each day for approx. 10 seconds to protect it against
corrosion.
With setting OFF the summer switch-off is not effective.
Hot water preparation is not affected by summer switch-off.

The legionella protection serves to avoid a legionella infestation
inside the hot-water tank and is activated on the selected weekday (Mon to Sun) or every day at 2.00 o’clock. If the hot-water
temperature should drop below 65 °C, the tank is reloaded.

This parameter refers to the type of the heating system
and has to be adapted to the power characteristic of the
corresponding consumer (underfloor systems, radiator,
convector). The setting value specifies the curvature of the
heating curve of the selected weather dependent heating
circuit and compensates the system-related efficiency losses at lower temperatures by a progressive heating curve
in conformity with the adjustment.
Heating circuit name
This is used to assign an individual, 5 character, abbreviated name to each heating circuit.
No individual name is assigned if the setting "empty" is
used. The default abbreviated name appears.
