4.2 Operation
The operation is split over three control levels. Control levels 1
and 2 are accessible to users and contractors alike. Control level
3 is reserved for qualified contractors:
Control level 1
(control flap closed)
Here, the operating mode, such as standby operation, programmed
operation, constant day and setback operation of the DHW program
can be adjusted.
Control level 2
(control flap open)
Here, system parameters, such as DHW temperatures, etc. can
be adjusted.
Control level 3
(for contractors only)
This level is access protected by a code and should only be used
by a contractor. Here, you can determine the specific details
regarding the heat pump and the heating system.
4.3
Essential facts in brief
Settings
All settings follow the same pattern:
Opening the control flap toggles the manager into programming
mode. An indicator symbol
is shown at the bottom of the display
at system parameter
ROOM TEMP
. Turning the rotary selector
allows you to move the indicator to the system parameter you
want to change.
To change the system parameter, press . Whenever the red
indicator above illuminates, you can modify the current value
by turning rotary selector . Press again, the indicator then
extinguishes and the new set value has been saved. You can
modify further values for this parameter by pressing , if the red
indicator above has not been extinguished after saving. The
programming step can only be terminated when the red indicator
has gone out.
Terminating the programming process
You can terminate the programming process after entering
and saving the required parameter changes by closing the
control flap. However, if you want to make further changes,
turn the rotary selector
until the display shows
BACK
,
then press . This will return you to the previous level.
Closing the control flap with illuminated indicator above
returns the manager to its original position. The modified value
will then not be saved.
Please read
During commissioning, a system check will be
implemented, e.g. all sensors that are currently
connected are displayed upon request. Sensors
not connected before the system went 'live' are not
registered by the manager and are therefore not
displayed. The indicator symbol skips such system
parameters.
Example:
The system parameter
SOLAR TEMP
will be skipped if,
at commissioning, the solar collector sensor was not connected.
Values for these parameters, therefore, cannot be programmed.

Operating modes (control level 1)
The operating modes are changed by turning the
rotary selector
with the control flap closed.
Standby
mode
Frost protection is activated for DHW operation. The display
indicates frost protection when the flap is closed. Ventilation runs
in setback mode.
Application: During holidays.
At control level 2 under parameter
VENTILATION
, ventilation can be
completely stopped. For this, adjustments are required on the
third operating level. These must only be carried out by a heating
contractor.
