04:1 to Controller amplification adjustable from 1 to 10 %/K
04:10
Explanations
05:10 Min. speed of solar circuit pump 10 % of max. speed
05:2 to Minimum speed of the solar circuit pump adjustable
05:100 from 2 to 100 %
Explanations
06:75 Maximum speed of solar circuit pump 75 % of max.
speed
06:2 to Maximum speed of solar circuit pump adjustable from
06:100 2 to 100 %
Explanations
07:0 Interval function of the solar circuit pump switched off
07:1 To capture the collector temperature more accurately,
the solar circuit pump periodically starts for a short du-
ration.
