During normal operation, the parameters adjusted by me-
ans of the commissioning assistant can be accessed in the
expert area of the adjustment values menu (see chap. 15).
If they are to be changed, this can be done in the following
submenus:
• Volume adaptation (pipe parameters etc.)
• Country parameters (country, time zone etc.)
• System parameters (tilt angle, orientation etc.)
11.3 Adjusting the minimum pump speed
Note:
The adjustment values in the expert area should
only be altered by qualified personnel. Other-
wise, the system may not function faultlessly!
After the commissioning assistant has been successfully
completed, the minimum speed of the pump must be adju-
sted. To do so, proceed as follows:
Î
Keep button 3 pressed for approx. two seconds
The main menu appears.
Î
Select “Adjustment values”
Î
Scroll down to “Relay mode” by pressing button 2
Î
Select “Relay mode” by pressing button 3
Î
Select “Min.” and confirm by pressing button 3 again
In the menu line below “Relay mode”, the adjustment
channel “Min. speed” appears, in the line below that, the
current flow rate is shown.
Î
Select “Min. speed”
Î
Adjust the minimum pump speed so that the flow rate
reaches the desired value
Î
Confirm by pressing button 3

Adjustment values
Note:
Observe the specifications of the pump and
the collector manufacturer when adjusting the
minimum pump speed!
If the flow rate remains below 100 l/h at the
adjusted minimum pump speed, the control-
ler will increase the pump speed until the flow
rate surpasses 100 l/h.
After the adjustment of the minimum pump speed,
the relay mode should be set back to “Auto”.
Otherwise, the efficiency and reliability of the system will
not be optimal.
To do so, proceed as follows:
Î
Select the menu item “Relay mode” as described above
Î
Select “Auto”
Î
Confirm by pressing button 3
For more information about the different relay modes see
chap. 15.3.
Note:
The system takes about 30 seconds to adjust to
a new minimum speed. Always wait for 30 se-
conds before readjusting the minimum speed!
