The system pressure is monitored by the pressure
sensor (B). When the pressure is below a certain
value the controller (F) switches ON the pump

that is stored in a breaktank. The controller will
switch OFF the pump after an adjustable pressure
difference is reached. The refill time and -amount
is protected and can be adjusted as welI.

The breaktank uses a float switch to maintain its
capacity. The breaktank has a overflow protection
(G) and a run-dry sensor (E) to maintain a safe
water level of breaktank. The impuls water
counter gives information about the amount of
water that is refilled in total.
