Control of the backwashing valves

NOTICE!
The default state of the backwashing valves is deener‐
gised (voltage free)
Fault: No backwashing is possible if the backwashing
valves cannot be controlled.
Consequence: The hygiene parameters worsen and
the hydraulic resistance of the filter increases.
Measure: Regularly check (dependent on the applica‐
tion) the operation of filter backwash.
An automatic 6-way valve cannot be used.
For backwashing there is, for example, the option of controlling a
Besgo rod valve.
®
To do this, the rod valve must be connected to terminal P3 in the P
module. If two circuits are in operation, the second rod valve must
be connected to terminal P2.
To activate this function, the function
[Backwash 2] must be activated in the P module.
Setting of the backwashing times is described under Timer set‐
Ä Chapter 4 'Timer settings' on page 12 .
