VENTILATOR OPERATION MODES
SIKU RV  W PRO WIFI V SIKU RV  DW PRO DUO WIFI V
Ventilation: the ventilator runs either in extract
or supply mode at a set speed.
In this mode, when two ventilators are installed,
one of them supplies and the other one extracts
the air.
Boost: the ventilator goes to the maximum speed
without changing the operation mode.
Regeneration: the ventilator runs in two cycles,
70 seconds each, with heat and humidity
regeneration.
Cycle I. Warm stale air is extracted from the room
and flows through the ceramic regenerator, which
gradually absorbs heat and humidity.
In 70 seconds, as the ceramic regenerator
gets warmed, the ventilator is switched to
supply mode.
Cycle II. Fresh intake air from outside flows through
the ceramic regenerator, absorbs accumulated
moisture and is heated up to the room
temperature.
In 70 seconds, as the ceramic regenerator gets
cooled down, the ventilator is switched to air
extract mode and the cycle is renewed.
If two ventilators are installed, they operate
with opposite rotation directions in this mode.
While one ventilator supplies air, the other
one extracts it.
Ventilation: one of the ventilator fans operates in
the air extract mode and the other one operates in
the air supply mode at a set speed.
The fans do not change their rotation direction.
Boost: if the sensor is actuated, the
ventilator follows one of two functioning
algorithms set via the DIP switch during the
ventilator setup. For details, see page 13.
The DIP switch is set to OFF: the ventilator runs
in the extract mode on the third speed (both fans
run in the extract mode). The DIP switch is set to
ON: the ventilator switches to maximum speed
without changing the operation mode.
Regeneration: one of the ventilator fans operates
in the air extract mode and the other one operates
in the air supply mode.
The fans change their rotation direction every
70 seconds.

In case of a failure the Alarm indicator on the indoor unit glows or blinks.
Reasons of alarm blinking:
• Battery charge is below the allowable limit
• No connection between the Master unit and the router
• Alarm shutdown of a ventilator.
If several interconnected ventilators are running in the same network, in case of alarm
shutdown of one SIKU RV 50 W Pro WiFi V2 ventilator, the Master-Unit and all the other
ventilators of this series will stop. The alarm display of the faulty ventilation system
flashes. At the same time, the master display flashes on the connected ventilation
systems (slave systems) that have been switched off. All the ventilators of the
SIKU RV 30 DW Pro Duo WiFi V2 series in the network continue to run.
In case of an emergency shutdown of the SIKU RV 30 DW Pro Duo WiFi V2 ventilator in
the network the defective ventilator does not influence the operation of other connected
ventilators in the network.
In case of communication loss of the Master unit with the router longer than 20 seconds
the Master unit goes to the Standby mode (blinking Alarm indicator) and the Slave units
will communicate communication loss with the Master unit (refer description of the Master
indicator). After resumption of the connection the Slave units automatically get
synchronised with the Master unit.
MASTER
Permanent glowing of the indicator indicates the Master unit.
Blinking of the indicator indicates the Slave unit and no connection with the Master

SENSOR SETUP
To set up sensor operation via the mobile application
go to
Menu - Settings -Sensors.
Humidity sensor: actuation of the humidity sensor.
When the indoor humidity exceeds the set point, the
ventilator goes to the third speed. When the indoor
humidity drops down below the set point, the turn-off
delay timer for the „Boost“ mode is activated. After
the delay timer countdown, the ventilator reverts to
the previous speed setting. Sensor 0-10 V: actuation
of the analogue 0-10V sensor. If the 0-10 V control
signal exceeds the set value, the ventilator goes
to the maximum speed. After decrease below the set
value the Boost delay timer is activated. After its
operation is completed the ventilator reverts to the
previous speed.
Relay sensor: Triggering of the external relay sen-
sor. After closing the normally open contact of the
external relay sensor, the ventilation system swit-
ches to the maximum ventilation level. After opening
the normally open contact, the switch-off delay for
the boost mode is activated. After the operation has
ended, the ventilation system changes to the previ-
ously set ventilation level.
Note: for activation /

FILTER TIMER RESET
WIRELESS CONNECTION OF SEVERAL VENTILATORS
RESET TO FACTORY SETTINGS
The ventilator filters must be serviced after every 90 days of continuous operation.
The need to replace the filters is communicated by the indicator in the upper
section of the Control menu. Replace the filter and reset the filter timer.
To reset the filter timer via the mobile application go to Menu – Settings – Filter.
Then press the Reset filter timer button.
The 90 days are counted on the Master ventilator only. The filter replacement
indication is replicated on all the Slave units. In this case replace the filters
on all the ventilators in the network. After filter timer reset, the filter
replacement indicator goes off on all the connected ventilators. The filter timer
can also be reset by means of the button on the indoor unit (see page 14).
The ventilator has two operation modes:
Master unit mode. The ventilator acts as a Master
unit. The Slave units and the mobile devices are
connected to the Master unit via the Wi-Fi
connection. The Master unit is controlled via the
mobile application, remote control or the sensor
buttons on the ventilator casing.
The control signal is automatically transmitted to
all the Slave units in the network. In this mode the
ventilator receives signals from the sensors
(humidity sensor, external digital sensor, external
0-10 V analogue sensor) and goes to a respective
operation mode.
Slave unit mode. The unit acts as a Slave unit in the
network. The ventilator responds to the control
signals from the Master unit only.
Any other signals from other controls are ignored.
In this mode the SIKU RV 50 W Pro WiFi V2
ventilators ignore signals from the sensors.
In case of communication loss with the Master unit
longer than 20 seconds the ventilator goes to the
Standby mode.
Sensor-actuated operation
The SIKU RV 50 W Pro WiFi V2 ventilators respond to
the signal from the sensors in the Master mode only.
The SIKU RV 30 DW Pro Duo WiFi V2 ventilators respond
to the signal from the sensors in any mode
(Master or Slave).
In case of actuation of any sensors for
SIKU RV 50 W Pro WiFi V2, all the connected
SIKU RV 50 W Pro WiFi V2 ventilators go to the
maximum speed. The SIKU RV 30 DW Pro Duo WiFi V2
ventilators continue to run with the same speed.
In case of actuation of any sensors for
SIKU RV 30 DW Pro Duo WiFi V2 only the affected
ventilator goes to the maximum speed according to
the humidity control scenario. The rest of the
ventilators continue to run with the same speed.
To reset to the factory settings via the mobile application go to
Menu - Setting - Factory settings.
Then press the Reset to factory settings button..
WARNING!
Reset to the factory settings may result in losing Wi-Fi connection with the device.
