DESIGN AND OPERATING PRINCIPLE
The ventilator consists of an indoor unit with a decorative front panel, a cartridge, an air duct 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 a semi-automatic air damper that closes during shutdown of the ventilator and prevents air backdraft.

VENTILATOR DESIGN
Outer ventilation hood Protects the unit from ingress of water and foreign objects. Each ventilator model has a matching ventilation hood model.
Mounting frame Facilitates mounting of the ventilator in thin walls
with the thickness from 135 mm.

Indoor unit rear side The unit includes a circuit control board
and touch buttons.

Telescopic air duct Plastic air duct
Cartridge Assembly unit consisting of a fan, a regenerator and air filters. Generates air flow, provides energy regeneration and air cleaning.

Indoor unit front panel Equipped with a semi-automatic air damper that closes up the air duct at the ventilator power off.
VENTILATOR OPERATION MODES The ventilator has three operation modes: Ventilation: the ventilator runs either in the air exhaust or air supply mode at a set speed. Air supply (available from a mobile device only): all the connected ventilation units in the network are in the air supply mode. Regeneration: the ventilator operates in reversed mode with heat and moisture regeneration, simultaneously cycling the direction of air flow. Cycle I. Warm stale air is extracted from the room and flows through the ceramic regenerator, which gradually absorbs heat and humidity. Cycle II. Fresh intake air from outside flows through the ceramic regenerator, absorbs accumulated moisture and is heated by the heat stored in the regenerator.
The ventilator is equipped with an air humidity sensor and a terminal for connecting an external normally open contact (relay sensor). When either of these devices is triggered, the ventilator switches to maximum speed (Boost mode). When the humidity sensor or relay sensor returns to its original position, the Boost mode deactivation delay timer is started.
In the relevant sections of the Blauberg Home mobile app, the following ventilation parameters can be set: · activate or deactivate the humidity sensor and relay sensor; · set the humidity sensor activation threshold; · set the Boost mode turn-off delay time (default setting is 30 minutes); · set the duration of the first speed timer («Night mode») (8 hours by default); · set the duration of operation by timer of the third speed («Party mode») (by default 4 hours).

If required, in the Schedule section of the Blauberg Home mobile app, different ventilation speeds can be set at different intervals by day of the week. For the weekly schedule to work correctly, the current date and time must be set correctly in the «Date and time» section When simultaneously activating several operation modes that exclude each other, the ventilator selects the mode according to the following priority: 1. Night mode timer or Party mode timer. 2. Standby. 3. Boost. 4. Weekly schedule. 5. Standard mode.
SEMI-AUTOMATIC AIR DAMPER OPERATING PRINCIPLE
The indoor unit of the ventilator is equipped with a front panel with a semi- automatic air damper. During the ventilator operation the air damper opens and lets the air flow freely through the ventilator. After switching off the ventilator, close the damper by hand to prevent drafts.

ON/OFF

Speed The speed selection sequence is follows: I-II-III. All the units integrated in a single network operate according to the speed settings of the Master unit. I: permanent indicator glowing indicates operation of the unit at Speed I. Indicator blinking indicates activation of the Night mode timer. I and II: permanent glowing of these indicators indicates operation of the unit at Speed II. I, II and III: permanent glowing of these indicators indicates operation of the ventilation unit at Speed III. Simultaneous flashing of indicators I, II and III indicates operation of the Party mode timer or Boost- mode switch-off delay timer when the built-in humidity sensor or an external relay sensor is triggered. Alternate blinking of the indicators I, II and III indicates that the ventilator runs at the speed set with the mobile application using the slider selector for manual speed setting or that the Weekly Schedule mode is activated.
Regeneration mode The ventilator works in reverse mode. Heat recovery is performed in this mode. To enable reverse phase operation of the ventilators, change the position of the DIP switch No. 3.

Contamination indicator of filters. The indicator light will start flashing after the preset number of days of continuous
ventilation operation (90 days by default) has elapsed.
In this case, clean or replace the filters (see section Technical maintenance).

Alarm indicator. In case of failure, the Alarm indicator on the indoor unit glows or blinks.
Causes of constant illumination of the indicator light: · Alarm shutdown of the ventilator. Stopped due to a faulty ventilator in the group.
Reasons of Alarm blinking: A · Battery charge is below the low level.
· No connection between the Master unit and the router. · Alarm shutdown of the ventilator. This ventilator causes all ventilators in the group to stop.
In case of communication loss of the Master unit with the router for longer than 20 seconds, the Master unit switches to Standby mode and the Slave units will signal that there is no communication with the Master unit.
After resuming communication, the Slave units are automatically synchronised with the Master unit.
Ventilation mode. The ventilator operates in the supply or extraction mode at a set speed. The fan rotation direction depends on the position of the Speed controller switch DIP No. 3.
No glowing of the indicators “Regeneration” and “Ventilation” indicates forced operation of the ventilation unit in the air supply mode. This mode may be activated only via the mobile device.
Permanent glowing of the indicator shows the leading unit (Master) in the group. M Indicator blinking indicates the driven Slave unit) and no connection to the Master unit.
No glowing of the lamp indicator means that this ventilation unit is a Slave ventilation unit and it is connected to a Master unit. Synchronous blinking of all the indicators on the casing of the ventilator indicates that the Setup mode is enabled.

TECHNICAL MAINTENANCE
DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS!
MAKE SURE THE UNIT IS DISCONNECTED FROM POWER MAINS BEFORE REMOVING THE PROTECTION.
Maintenance of the ventilator means regular cleaning of the ventilator surfaces of dust or replacement of the filters. Clean the filters as often as required, but at least 3 times a year. After 90 days of continuous operation (default duration), the filter change indicator (Filter) lights up on the ventilator. To access the main serviced units, disconnect the ventilator from power mains using a circuit breaker or a power switch and follow the steps below. 1. Press the lower latch of the indoor control unit to take off its front panel. Please make sure the thermal actuator rod is in lower position during reinstallation of the front panel. If the rod is up, please wait for about 2 minutes until it goes down. 2. Disconnect the connector from the circuit board. Do not remove the connector by pulling the wires. Use a flat screwdriver to uplift it, if required. 3. Remove the cartridge from the ventilation duct. 4. Remove the filters from the cartridge for cleaning. Wash the filters and let those dry out completely. Install the dry filters in the air duct. Vacuum cleaning is allowed. The filter rated service life is 3 years. 5. Perform all the above operations in the reverse order after cleaning.

Remove the filters from the cartridge.

Do not pull the wires!

Use a flat screwdriver to disconnect the connector.

Restart the filter timer countdown in the Blauberg Home app on a mobile device or by holding down the unit for 5 seconds before the beep.
