Collector
Protection
The collector protection function can be switched ON or OFF.
Note
Even if the operation mode of the solar thermal system is OFF, the collector
protection is active, provided that it is turned on. This serves to protect the
solar thermal system.
Collector Protection
Protection Temp
If the collector protection function is activated and the collector sensor reaches
the protection temperature, the DHW pumps and heating circuit pumps switches
on. Further the mixer open till the maximum flow temperature is reached. This
process stops if the collector temperature rises until the Solar Switch off / Collector
Overheating.
Note
The collector protection must be set lower than the Solar Switch off /
Collector Overheating.
Collector Protection
Protection Temp Hyst
This process also stops when the collector temperature falls below the collector
protection temperature minus protection temperature hysteresis falls.
Scavenging
Mode
You can switch Scavenging ON and OFF. The scavenging process compensates
different temperatures in the solar circuit.
Scavenging
Rest Time
Scavenging
With Rest Time and Run Time you set the scavenging interval.
Scavenging
Collector Temp Min
If the collector temperature is below the collector temperature minimum, the
scavenging process is not performed.
Scavenging
Start Time
Scavenging
Stop Time
With the Start Time you set the beginning of the scavenging process.
Start and Stop time are avoiding an unnecessary operation of the solar circuit pump.
Prio
Mode
Systems with more than one solar hot water cylinder/combination cylinder.
Select priority of solar cylinders. Allows cascade function loading of cylinders.
Cylinders can be loaded in series cascade or in parallel.

Scavenging Time
Set the solar pump pulse programme for solar circuit PRIO 2.
Only for solar circuit PRIO 2 it is necessary to set the solar pump pulse programme.
After the scavenging period of solar circuit PRIO 2 follows the scavenging interval of
both solar circuits.
After the scavenging interval follows the scavenging time.
During the scavenging time the solar circuit checks, if there is a new demand for
PRIO 1 or not.
If there is a demand for solar circuit 1, the pump runs, if not the scavenging period of
solar circuit 2 starts.
If during the scavenging period of solar circuit 2 there is a demand from solar circuit
1, it will be immediately fulfilled.
