Backwash control
The factory-provided inserted bridge between clamps
13
and
14
must be removed on
connecting a level control NR-12-TRS-2. If no level control is connected, the bridge
between these clamps will have to be kept screwed in. In this case the clamps
11
and
12
will remain unused. The clamps drive mains voltage!
The factory-provided inserted bridge between clamps
3
and
5
has to be removed on
connecting a EUROTRONIK-10. If no EUROTRONIK-10 is connected, the bridge
between these clamps have to be remained screwed in. In these case clamps
2
and
4
will remain unused. The clamps drive mains voltage!
An opening of one of the contacts between clamps
13
and
14
or
3
and 5 will result in
an immediate switching off of the filter pump, the dosing equipment and the heating.
The closing of one of the contacts between clamps
2
and
4
or
11
and
12
will cause a
forced switch on of the filter pump, whereas the heating and the dosing equipment
will be switched off.

Dosing equipment
(floating)
max. 230V / 4A
In the control unit there is a floating relay contact
between the clamps 20 and 21. This can for instance be
used to control the dosing equipment (the contact will be
closed during the filter operation).
This contact can be charged with a maximum of
230V/4A.

The pool temperature sensor is connected to the clamps 30 and 31. As a standard
the temperature sensor is delivered with cable length of 1.5m. If required, this can be
lengthened with a two-core cable (minimum diameter 0,5mm²) up to a maximum of
20m. It should be avoided to lay the sensor lead near power lines to exclude possible
disturbance.
