Potential-free contact load
Min. system pressure
Min. working pressure values at
the suction port depending on
temperature
**
for standard installations this condition is met when the initial system pressure is set following the formula (see the collector guide):
p = 1,3 + 0,1·h
[bar]
,
where h … height from the pressure gauge to the middle of the collector array [m]
*
the pump station may be used also for systems with a higher flow rate than 20 l/min, then the controller will show the flow rate value
as > 20 l/min.
