Function
The electronic backwash controller EUROTRONIK-20 switches the filtration pump of a swimming-pool on
and off at programmable times and controls the backwashing and clear rinsing cycles for cleaning the
filter. The EUROTRONIK, which is mounted on the 6-way valve with a protected quick coupling,
automatically moves the valve into the correct position and operates the filter pump. The time of the
backwashing and clear rinsing cycles is adjustable and can be seen in the LCD display.
The backwashing cycle can be carried out both on a
time-control
(by way of the integrated digital switch
clock) as well as
pressure-dependent
basis. The adjustable pressure switch (art. no. 2000599015) is not
included in the delivery package. It is also possible to start the backwashing cycle manually with a key in
the housing cover.
A connection for a 230 V motor-operated valve enables withdrawal of the water needed for the
backwashing cycle directly from the swimming pool instead of from the overflow collecting tank and
replenishment of fresh water during backwashing.
An additional floating relay contact can be used
during backwashing to operate a second pump (backwash pump or blower).
A connection for an external temperature regulator provides the possibility of heating the pool during the
filtration times. An internal latch makes sure that the heater will only be enabled when the pump is running.
To empty the swimming pool, the 6-way valve can be moved into the position
Empty
. The key for this is
also located in the housing cover.
For maintenance purposes the valve can also be moved into the
position Closed with a further key.
The respective valve position and position changes can be read on an LCD display in the housing cover
without having to open the housing. The valve disk is lifted before turning to protect the star seal. The
pump is switched off during this time.
