Term Description
Settings 1
Program number Activation of the solar program number according tohydraulic scheme.
Antifreeze
Setting up the collector temperature which conducts a permanent running
of the solar pump to avoid freezing.
Flow rate Here, a constant flow can be adjusted (0 till 99,9
Rotation speed
control
When activating this parameter, the rotation speed control is activated and
the pump is controlled via pulse width modulation
(Attention: use suitable pumps!)
Min. rotation speed Is the min. rotation speed/control of th
Must value
Must temperature of the rotation speed control (middle collector
temperature).
The larger the must temperature, the smaller the rotation speed
Control difference
Is a measure of the pump rotation speed.
