The settings of the primary store system can be adjusted in the user
interface under DHW system I. The DHW parameters are described in
the user interface.

Diagnostic menu

The menus depend on which user interface and which solar system is
installed.
Function test
CAUTION: risk of scalding if cylinder temperature limiter
deactivated during the function test!
▶ Close all DHW draw-off points.
▶ Inform occupants of the premises of the risk of scalding.
If an MS 200 module is installed, the Solar, Transfer or DHW menu is
displayed.
This menu can be used to test the pumps, mixers and valves of the
system. They are tested by setting various setting values. You can check
whether the mixer, pump or valve responds appropriately by inspecting
the behaviour of the corresponding component.
• Mixer, valve, e.g. 3-way mixer (CH backup mixed)
(Control range: Closed, Stop, Open)
– Closed: Valve/mixer closes fully.
– Stop: Valve/mixer remains in its current position.
– Open: Valve/mixer opens fully.
Monitored values
If a MS 200 module is installed, the Solar, Transfer or DHW menu is
displayed.
This menu allows you to call up information on the current status of the
system. For example, the system can display whether the maximum
cylinder temperature or the maximum collector temperature has been
reached.

Purpose of the menu
Adding functions to the transfer system.
Graphical display of the transfer system that is currently configured.
Settings for the installed transfer system.
If the differential set here between cylinder 1 and cylinder 3 is exceeded and all conditions for switching on have
been met, the transfer pump is on.
If the differential between cylinder 1 and cylinder 3 falls below the value set here, the transfer pump is off.
If the temperature set here is exceeded in cylinder 1, the transfer pump is off.
Start time for daily heat-up. Daily heat-up ends after a maximum of 3 hours.
Daily heat-up ends once the set temperature is reached, or, if the temperature is not reached, after a maximum of
3 hours.
If the transfer system develops a fault, the output is activated for a fault display.
If the transfer system develops a fault, the output is not activated for a fault display (always de-energised).
The fault display is activated, but the inverted signal is output. This means that the output is energised and is
de-energised with a fault display.
The tab. below provides a brief overview of the Transfer settings menu.
The menus and available settings are described in detail on the following
pages. The menus depend on the installed user interface and the
installed system.
The information and values that are provided depend on the system that
has been installed. Observe the documents for the heat source, user
interface, additional modules and other system components.
The menu item Status shows the status of the component relevant to the
function for example, under the menu items solar pump, Central
heating backup or Transfer.
