UNIT DESIGN AND OPERATING PRINCIPLE
The ventilator consists of an indoor unit with a decorative front panel, a cartridge, an air duct with a sound absorbing mat and an outer
ventilation hood.
Cartridge is the basic functioning part of the ventilator. The cartridge consists of a fan, a regenerator and two filters that ensure rough air
filtration and prevent ingress of dust and foreign objects into the regenerator and the fan.
The indoor unit is equipped with an automatic air damper that closes during shutdown of the ventilator and prevents air backdraft.

VENTILATOR OPERATION MODES
The ventilator has three operation modes:
Ventilation: the ventilator runs either in extract or supply mode at a set speed.
Air supply (available from a mobile device only): all the connected ventilators in the network go to the air supply mode.
Regeneration: the ventilator runs in the reversible mode with heat and humidity recovery.
In the Regeneration mode the ventilator operates in two cycles.
Cycle I. Warm stale extract air flows through the ceramic regenerator and heats it up and moisturizes the regenerator.
Cycle II. Fresh and cold intake air from outside flows through the ceramic regenerator, absorbs accumulated moisture and get heated up
to the room temperature with the heat accumulated in the heat exchanger.

CONNECTION TO POWER MAINS AND CONTROL
POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.
THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE
MANUFACTURER’S LABEL.
ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED
AND WILL VOID THE WARRANTY.
SIKU RV 25 W Pro WiFi V2
The ventilator is rated for connection to single-phase
AC 100 - 240 V / 50 (60) Hz power mains. The installation of power
cables is described in the Installation and set-up section.
Connect the unit to power mains uing durable, insulated and heatresistant conductors (cables and wires). The total minimum cross
section for the power cable must be 0.5 up to 0.75 mm2. The actual
wire cross section selection must be based on the maximum load
current, maximum conductor temperature depending in the wire type,
insulation, length and installation method.
Use copper wires for all the electric connections!
Connect the unit to power mains via the terminal block in compliance
with the wiring diagram and terminal designation. Connect the
ventilator to power supply through an automatic circuit breaker with
electromagnetic trip integrated into the home wiring system. The
rated trip current of the automatic circuit breaker or the safety fuses
must exceed the maximum current consumption of the unit, refer to
the Technical data section.
The recommended trip current of the circuit breaker or safety fuse is the
next current in the standard trip current row following the maximum
current of the connected unit.

The speed selection sequence is follows: low-medium-high. The speed of all the interconnected ventilators in the
network is set with the Master unit.
I: permanent glowing of the indicator indicates running of the ventilator at the low speed.
Blinking of the indicator indicates activation of the timer Night mode.
I and II: permanent glowing of the indicators I and II indicates running of the ventilator at the medium speed.
I, II and III: permanent glowing of the indicators I, II and III indicates running of the ventilator at the high speed.
Synchronous blinking of the indicators I, II and III indicates activation of the timer in the Party mode or the
turn-off delay timer in the Boost mode in case of triggering of the integrated humidity sensor or the connected
external relay sensor. Alternate blinking of the indicators I, II and III indicates running of the ventilator at the speed
set with the mobile application using the slider selector for manual speed setting or activation of the scheduler.
Regeneration mode
Rotation direction of the fan is changed. Heat regeneration is accomplished in the Regeneration mode. To
enable operation of the ventilators in opposite direction change the position of the DIP switch No. 3.
Filter clogging indicator. The indicator starts blinking 90 days after installation of the cartridge. In this case clean
or replace the filters (see the «Technical maintenance» section).
F
After replacement of the filters reset the filter timer using the mobile application or press and hold the
button on the indoor unit of the Master unit for 5 seconds, until a signal beeps.
Alarm indicator. In case of a failure the Alarm indicator on the indoor unit starts to glow or to blink.
Reasons for glowing of the indicator:
• Alarm shutdown of a ventilator caused by another defective ventilator in the network.
Reasons of alarm blinking:
A
No glowing of the indicators «Regeneration» and «Ventilation» indicates activated supply ventilation mode of the ventilator..
M
Synchronous blinking of all the indicators on the ventilator casing indicates the activated Setup mode.
• Battery charge is below the allowable limit
• No connection between the Master unit and the router
• Alarm shutdown of a ventilator. This ventilator causes shutdown of all interconnected 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 and the Slave units signal of communication loss with the Master unit. After resumption
of the connection the Slave units automatically get synchronized with the Master unit.
Ventilation mode
The ventilator operates in the supply or extract mode with the set speed. The fan rotation direction depends on
the position of the DIP switch 3.
Permanent glowing of the indicator identifies the Master unit in the network.
The blinking Indicator identifies the Slave unit in the network and no connection with the Master unit.
No glowing of the indicator identifies the Slave unit connected with the Master unit.

WIRELESS CONNECTION OF SEVERAL VENTILATORS
The ventilator has two operation modes.
Master unit (Master). 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 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 responds to signal from the sensors
and goes to a respective operation mode.
Slave unit (Slave). 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 ventilator does not respond to the signals from the sensors. In case of
communication loss with the Master unit longer than 20 seconds the ventilator goes to the Standby mode.
WIFI PARAMETER SETUP
Setup of the Wi-Fi parameters is only possible on Master units. To set up ventilator Wi-Fi parameters via the
mobile app go to Menu - Connection - WI-FI setup.
Press the Receive button to display the current Wi-Fi settings.
