Description of the solar function: When the switch-on temperature
difference between the swimming pool C1 (T3) and one or the other of
the collector arrays A1, A (T1, T) is reached, then either solar circuit
pump R1 for collector array A1 (T1), or solar circuit pump R for collector
array A (T) is switched on, depending on where the temperature dif-
ference occurs. When the switch-on temperature difference is reached
for both collector arrays A1, A (T1, T), then both pumps R1, R are
switched on. The pumps switch off independently of each other, when
either the relevant switch-off temperature between one of the collector
arrays A1, A (T1, T) and the swimming pool C1 (T3) or a safety limit
is reached.
Loading strategy of solar circuit pump R1: In the factory, the load-
ing strategy is set to temperature differential control. This cannot be
altered.
Loading strategy of solar circuit pump R2: It is not possible to select
whether temperature differential control or target temperature control
is to be used as the loading strategy. Solar circuit pump R operates
according to the switch-on and switch-off temperature difference
parameter values.
NOTE
In the factory, RPM control is deactivated for solar circuit pump R1. This
can be changed in the "Parameters" menu (chapter 7.4 "Parameters"). If
RPM control is activated, the loading strategy of solar circuit pump R1 is
set to temperature differential control. This cannot be altered.
Activating the system: see chapter 7.. "Selecting a system".
