First of all, the basic solar system can be selected ac-
cording to the number of stores and collector elds
in use. The corresponding numbers are indicated on
the display.
The exemplary gure shows system 6 with its 3
stores and 2 collector elds (east- / west collectors).
When the basic system has been selected and con-
rmed, the hydraulic variant can be selected. The va-
riant is visualised on the display by means of pump
and valve symbols. The exemplary gure shows vari-
ant 2 of system 6 with a 2-port valve and a pump. For
an overview of the basic systems and their variants
see chap. 5.2 on page 15.
The controller supports up to 2 collector elds and
up to 5 solar stores (with 2 collector elds only up to
4 solar stores).
Collector (1/2)
In systems with 2 collector elds, 2 seperate menu
items (Collector 1 and Collector 2) are displayed
instead of Collector.
For each collector eld, a collector minimum limita-
tion and a collector emergency shutdown tempera-
ture can be adjusted.
