Setting The Flow Rate
The pump may only be run when the system has been filled as dry operation will dam-
age the pump. The desired flow rate is 1 litre per minute per m² (10 tubes=0.93m² / 1
panel =1.91m² )
Set the pump to the first speed and run it manually
from the controller (see following paragraph).
If the desired flow rate is exceeded, set the flow me-
ter to the desired rate by adjusting the isolating valve
with a flat headed screwdriver (see diagram) with the
pump running. Otherwise repeat this step at the next
pump speeds and continue until the desired flow rate
is achieved. Stop the pump.
Turning The Solar Pump On Manually For Service:

and hold the down button for 3 seconds and the controller will enter the service
