•
Use a screwdriver (max. blade
width 3 mm) to press down the
plunger of the manual override
until the valve switches.
•
Then turn the plunger in a
clockwise direction one fourth of a
turn.
The pilot valve switches and controls
the power valve in the switching
position.
•
Remove the screwdriver. The valve maintains the switching
position.
•
With the screwdriver, turn the

The spring force presses the plunger
of the HHN into the basic setting.
The pilot valve returns to its neutral
