The fan casing is made of galvanized steel. The fan casing includes an exhaust spigot with a back draft damper to prevent back air flow.
The terminal box comprises the terminals for wiring of the fan and is attached to the fan casing. The decorative grille is fixed to the casing
via the springs inserted to the holders. The front panel is fixed via the grille slots. A single-phase electric motor with a centrifugal impeller
with forward curved blades is fastened inside of the casing. Depending on the fan model the fan may be equipped with a LED lamp, a
timer, a humidity or motion sensor.
Timer T
After an external switch, e.g. a light switch is turned off, the fan is turned on or goes to high speed after countdown of a set turn-on delay
time, adjustable from 0 to 3 minutes.
After the fan is turned off it keeps running for a set turn-off delay time, adjustable from 1 to 90 minutes and the reverts to the initial
operation status.
Motion sensor TP
In case of activation of the motion sensor the fan turns on or switches to the higher speed.
After no motion is detected more the fan keeps running for a set turn-off delay time, adjustable from 1 to 90 minutes, and the reverts to
the initial operation status.
Humidity sensor TH
If the indoor humidity exceeds the set humidity point adjustable from 50 % up to 90 %, the fan either turns on or goes to the higher
speed.
After indoor humidity drops down the fan keeps running for a set turn-off delay time, adjustable from 1 to 90 minutes and the reverts to
the initial operation status.
MOUNTING AND SETUP
READ THE USER'S MANUAL BEFORE INSTALLING THE UNIT.
The fan is a component part and is not designed for stand-alone operation.
The fan is constructed for ceiling installation in the floor slab and fixation to the inter joist with the distance between the ceiling joists
from 270 up to 680 mm using the removable fixing brackets or the fastening holes in the fan casing.
The installation place must be in compliance with local construction norms for units of this type.
Check the fan for mechanical damages prior to mounting .
Make sure that the casing comprises no foreign objects, such as paper or foil.
While mounting the fan sufficient service access for maintenance or repair operations must be provided.
The minimum gap between the fan and the ceiling is 5 mm.
L = 5 mm (min) L = 5 mm (min)

CONTROL
MICROPROCESSOR CONTROL UNIT WITH INDICATION
Indicator
Buttons
Connection
socket for humidity sensor
Connection
socket for motion sensor
The DC fan motor is operated by the microprocessor control unit. The front panel of the control unit comprises a light indicator, control
buttons and two sockets for connection of the humidity sensor and motion sensor.
After the fan is connected to power supply, the indicator displays
for two seconds. After that the light indicator goes off and the fan
starts operating in a set mode. Once the button
is pressed, the indicator displays the turn-off delay timer setting , the first setup
menu entry. Use the buttons
or to navigate in the setup menu. Press the button to select a current entry in the setup menu.
After that the indicator displays the selected parameter value (e.g., turn-off delay timer setting). Use the buttons
or to edit the
setting. Press the button
to come back to the setup menu. If no button is pressed for 60 seconds, the indicator goes down.
Example
The indicator displays
. Once the button is pressed, the setup menu list goes one position down and the symbol is displayed
(refer to the setup menu).
Once the button
is pressed, the indicator displays the turn-on delay timer setting, which can be edited with the buttons and .
Once the button
is pressed again, the setup menu is displayed again and the edited value is saved. To reset the menu to the factory
settings press and hold the buttons
and synchronously. In 5 seconds the indicator displays and goes off. The fan keeps
running normally with the factory settings.
INDICATOR SYMBOLS OF THE MICROPROCESSOR CONTROL UNIT
: turn-off delay timer adjustable from 1 to 90 minutes (default setting 15 minutes)
: turn-on delay timer adjustable from 0 to 180 seconds with the increment of 10 seconds (default setting 0)
: humidity set point adjustable from 50% up to 90% (default setting 75%)
: access to submenu of the fan operation mode
Operation mode
: the fan operates without any activation signal from the switch, humidity or motion sensor.
Operation mode
: the fan operates with activation signal from the switch, humidity or motion sensor.
: back to the upper setup menu level.
Once the switch is turned on or the humidity or motion sensor is activated, the fan switches from the mode
to the mode .
After no signal is received more from the sensor in case of the indoor humidity normalization or no motion detection or in case of the fan
shutdown the fan keeps running for a set turn-off delay time and then switches from the mode
to the mode .

MAINTENANCE
The fan maintenance includes regular cleaning of the surfaces of dust and dirt. Replace the filter as required, but at least every 6 months.
The impeller cleaning is shown below. Clean the impeller blades thoroughly every 6 months.
DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE
OPERATIONS.
SETUP OF THE OPERATION MODES AND
: the fan is turned off.
“60”, “70”, “80”, “90”, “100”, “110”, “120”, “130”, “140”, “150”: the fan runs to keep permanent air flow with set air capacity settings. The settings
are displayed in CFM.
The maximum air flow value is limited to 110 or 150 CFM, depending on the fan model.
“120”, “130”, “140” and “150” air flow values are not available for the fan with the air capacity 110 CFM.
Example 1
= , = : with these activated settings the fan runs to keep the air flow 60 CFM. Once the switch is turned on or a
sensor is activated, the fan starts to run with the maximum capacity.
That is a factory setting for the fans with the maximum air capacity 110 CFM.
= is applied for the fans with the maximum air capacity 150 CFM.
Example 2
= , = : with these activated settings the fan is off. Once the switch is turned on or a sensor is activated, the fan starts
running to keep the air flow 90 CFM.
This way by changing the
and parameters you can set a required operation mode.
