7.1 BASIC SETTING
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 number of collector fields and stores as well as hydraulic variant.
The number of collector fields and stores as well as the hydraulic variant have normally already
been adjusted in the commissioning menu (see page 113).
NOTE:
If the setting is changed later on, all adjustments for the solar part of the arrangement
will be set back to their factory settings.
If the change causes the solar system to require a relay or PWM / 0-10 V output that has
been allocated to an arrangement or heating function before, the relay / PWM / 0-10 V
output is removed from the non-solar function.
The controller supports up to 3 collector fields and up to 4 solar stores (with 2 or 3 collector
fields only up to 3 or 2 solar stores respectively).
The following items in the Solar / Basic setting menu will adjust to the system selected.
Collector (1 / 2 / 3)

In systems with 2 or 3 collector fields, up to 3 seperate menu items (Collector 1 to Collector 3)
are displayed instead of Collector.
For each collector field, a collector minimum limitation and a collector emergency shutdown
temperature can be adjusted.
Collector minimum limitation
If the collector minimum limitation option is activated, the corresponding pump is only switched
on if the adjustable minimum collector temperature is exceeded. A hysteresis of 2 K is set for
this function.
NOTE:
If the store cooling or antifreeze function is active, the collector minimum limitation is
suspended. In this case, the collector temperature may fall below the minimum tempera-
ture.
