Operating Instructions for the User
Operation
Closing the fresh air ducts
If the appliance is out of operation, the external air
ducts can be closed by means of the slider (Fig.1,
Pos.3) on the left hand side of the appliance.
The noise emission from outside is reduced through
this measure.
Setting 0 = closed; Setting 1 = Open
The operation of the ventilation radiator is done by
means of rotary knobs on the left hand side of the
appliance. A light press of the rotary knob causes it to
spring out; a further press pushes it back in again.
The rotary knob can be recessed at any setting.
Fan regulation
Front rotary knob I 6 5 4 3 2 1 :
The front rotary knob switches the fresh-air and
exhaust-air fans on and off. The fan speed can also
be infinitely varied using this rotary knob.
I
- Fan off
6...1 - Fan on
Knob setting 6: Maximum setting - approx. 60m³/h
Knob setting 1: Minimum setting - approx. 20m³/h
The direction of the rotary knob is from „I" to „6 5 4 3 2
1" and back. It is not possible to turn the rotary knob
from „I" to „1" or from „1" to „I".
We recommend the setting 2-3 for continuous opera-
tion (dependent on the size of the room). If increased
ventilation is necessary, the fan speed should be tem-
porarily increased. This naturally also increases the
noise of operation.
Operation mode switch
This rotary knob is factory set for only fresh air and
exhaust air operation and may only be freed for other
operations in dwellings in which the appliance has not
been designed in according to the German Energy
Saving Regulations. To free the switch, consult your
installer.
