Turning the ventilator off is not allowed.
The switch position disables deactivation of the ventilator with the button on the side control panel.
Fan rotation direction:
For controlled ventilation it is recommended to install the ventilators pairwise and integrate them in a group using a signalling cable.
Set one half of the connected ventilators into supply mode and the other half into extract mode.

Air supply
This positioning of the switch enables supply operation of the ventilator in Ventilation mode.
In Regeneration mode the ventilator starts operating first in supply mode.
2
Air extract.
This positioning of the switch enables extract operation of the ventilator in Ventilation mode.
In Regeneration mode the ventilator starts operating first in extract mode.
Humidity sensor setpoint
The humidity sensor measures the extract air humidity.
If the extract air humidity is above the set point, the ventilator switches to high speed.
As humidity drops down to the set point, the ventilator changes to pre-set speed after elapsing of the run-out time.

Run-out timer
During activation of the humidity sensor or any other control unit the ventilator switches to higher speed.
After standardization of the indoor humidity or any other air parameters the ventilator returns to a previously set mode in set
time period.

Speed setting
Ventilation mode
The ventilator operates either in
extract or supply mode at set speed
depending on positioning of the
DIP-switch on the circuit board.
Filter indicator
After the set filter replacement
periodicity has expired the Filter
indicator starts glowing.
In this case clean or replace the
filters.
Alarm indicator
In case of the motor jam the Alarm
indicator starts glowing and the
ventilator stops.
All the connected in series ventila-
tors stop synchronically.
Master indicator
Indicator of the first ventilator in the
group.
Regeneration mode
Air flow direction changes once in
70 seconds and the ventilator
changes between supply and extract
mode.
Heat regeneration is performed in
this mode.
Speed/off
The speed setting engages
cyclically: I-II-III-Off.
A respective indicator starts
glowing during speed setting.
Buttons on the
ventilator casing
Remote control
VENTILATOR CONTROL
The ventilator can be operated with the remote control or the control buttons on the side part of the indoor assembly unit, as
figured below.
In case of in-series or parallel connection the signal from a control unit is received by the first ventilator (Master) only.
