Description
: This function controls the solar circuit of your
solar system. The factory settings guarantee you the best
possible utilization of the available sunlight.
The “T.Coll.ACT” line shows the temperature of the col-
lector at the hottest point. At “DIFF.ON” and “DIFF.OFF”,
you can read the switch-on and switch-off temperature
differences, respectively.
The temperature at the S3 storage tank reference sensor
(see system diagram in the appendix) can be read at
“T.Ref.ACT” and the temperature at the hot water buffer
temperature sensor (S1) can be read at “T.Lim.ACT”.
