Functional description of the general operating mode of the pump control
The pump control consists of a pressure switch and a water flow switch. The switching cycles are then
determined from the two switching states of the pressure switch and the water flow switch.
•
Water pressure switch actuated + water flow switch not actuated = normal switch-off (delay of
approx. 3–8 s. until switch-off)
•
Water pressure switch not actuated + water flow switch actuated = pump on
•
Water pressure switch not actuated + water flow switch not actuated = switch-off due to dry
running and indication of fault (delay 8–15 s)
Common causes of errors
1. First case:
The pump control switches off and displays failure/error even though water has been pumped
successfully before. After a reset, this error will reoccur immediately or after a short time.
Possible causes:
a) The water pressure of the pump used is not sufficient to operate the water pressure
switch. (Causes can be a blockage, a worn pump body or a pump that is too weak).
b) The water pressure switch in the pump control is blocked. (Cleaning with clean water
can solve the problem or the housing of the pressure switch in the pump control must
be cleaned. Sand and other sediments may have deposited here.)
2. Second case:
The pump control leaves the pump permanently switched on regardless of whether the tap is
open or closed.
Possible causes:
a) The installation position of the pump control was not taken into account. This does not
reset the water flow switch and it is permanently actuated. (Check installation position
and correct if necessary.)
b) The water flow switch at the pump control input is permanently actuated. This can be
caused by contamination, calcification or a foreign body. (An optical check confirms this
problem and can be corrected by cleaning.)
