INSTALLATION / COMMISSIONING
Changing the cable outlet direction
➔ ➔ ➔ ➔ ➔ Unscrew the 4 screws on the front of
the controller and remove the cover
carefully
➔ ➔ ➔ ➔ ➔ Remove the screw to the valve and
remove the plastic cross.
➔ ➔ ➔ ➔ ➔ Detach the plate from the cube.
➔ ➔ ➔ ➔ ➔ Pull out the cube downwards and
replace in the desired orientation.
➔ ➔ ➔ ➔ ➔ Place the plate onto the cube
(the pins must engage in the
guides.)
➔ ➔ ➔ ➔ ➔ Lay on the plastic cross and insert
the screw through the cube.
➔ ➔ ➔ ➔ ➔ Connect the controller to the
proportional valve.
