Basic solar settings
In this menu, all basic settings for the solar part of the arrangement can be adjusted.
In this menu, the hydraulic system, which is the basis for the arrangement, can be
adjusted. The setting is divided into systems and variants.
Both system and variant have usually been adjusted during commissioning. If the
setting is changed later on, all adjustments for the solar part of the arrangement
are set back to their factory settings.
If the change causes the solar system to require a relay that has been allocated to
an arrangement function before, all adjustments made in the non-solar function will
be set back to their factory settings as well.
First of all, the basic solar system can be selected according to the number of
stores and collector fi elds in use. The corresponding numbers are indicated on
the display.
The exemplary fi gure shows system 6 with its 3 stores and 2 collector fi elds
(east- / west collectors).
When the basic system has been selected and confi rmed, the hydraulic variant can
be selected. The variant is visualised on the display by means of pump and valve
symbols. The exemplary fi gure shows variant 2 of system 6 with a 2-port valve and
a pump. For an overview of the basic systems and their variants see page 17.
The controller supports up to 2 collector fi elds and up to 4 solar stores (with 2
collector fi elds only up to 3 solar stores).
