2K (hysteresis fixed).

"If the collector temperature can only be registered
with insufficient accuracy, optimisation is possible
using the starting aid function. Due to a positive
temperature change at the collector sensor, the solar
pump is switched on for a limited run time (08-017).
The pump switches off again at the end of the time.
TKO is measured. If the temperature difference in
relation to the storage tank is sufficient, the solar
pump switches "On". If the switch-on criteria are not
met, the solar pump is switched on again after
a variable waiting time (15 to 100 minutes).
The waiting time is defined on the basis of TKO and
the temperature change.
A starting aid for the solar pump is activated in
position "on"."

The collector controller has a PID control. The set P
share determines at which reference value deviation
100% setting command is generated for the speed
control.

The reset time influences the speed at which the
speed control corrects a reference/actual value
deviation. The setting value defines after how many
minutes a doubling of the gap from the minimum
manipulated variable (08-035) is required.
