AIR ADJUSTMENT WITH DAMPER MOTOR
The damper motor turns the damper
between 3 preset positions: fully
closed, low capacity and high capa-
city. These positions are controlled in
the motor by cams which are set by
means of the coloured disks. In ad-
dition there is a black disk controlling
the connection of solenoid valve 2.
If the air volume needs changing:
Remove the cover from the damper
motor and change the position of the
cams by turning them by hand. See ig.
Low capacity:
Adjust the operating switch to high
capacity (II).
• Reduce the air volume:
Turn orange cam towards 0°.
• Increase the air volume:
Turn orange cam towards 90°.
Adjust the operating switch back to
low capacity and check.
Full capacity:
Adjust the operating switch to low
capacity (I).
• Reduce the air volume:
Turn red cam towards 0°.
• Increase the air volume:
Turn red cam towards 90°.
If the red cam is moved, change the
black cam as much. Adjust the opera-
ting switch back to high capacity and
ensure that the correct air volume has
been obtained.
Note!
The blue cam is the limit position for
fully closed damper and it is normally
not necessary to change it.
Releasing button
By pressing the button and snapping
it down, the motor will be released
and the damper can easily be turned.
This function facilitates an exchange
of damper motor.
