Description
When the temperature on the secondary side in
the heat exchanger reaches 3 K below the defined
maximum value, the solar circuit pump is switched
off and the storage tank loading pump continues
to run. When the temperature drops back down
to 10 K below the maximum value, the solar pump
switches on again. If the defined maximum value
is nevertheless reached, the storage tank loading
pump also switches off, for safety reasons. When
the temperature returns to below the maximum
temperature, the storage tank loading pump
switches on again.

Description
It is possible to choose between temperature differential loading and target temperature loading. Depending on the selected loading strategy,
the controller either attempts to comply with the
defined temperature difference between collector
and storage tank, or to reach the defined target
temperature as quickly as possible. See chapter
7.4.2 for information regarding settings.

If RPM control is activated, the power at the controller's output R1 is regulated by means of full-wave
packet control, according to the measured temperature values and controller settings.
When RPM control is deactivated, full power is
present at the controller's output R1. See chapter
7.4.3 for information regarding settings.
