Overall Dimensions of the Indoor Unit [MM]:

Diagram Description: A diagram shows the indoor unit dimensions. For VENTO inHOME Wi-Fi models, the outer diameter is Ø 160 mm. For VENTO inHOME Wi-Fi mini models, the outer diameter is Ø 103 mm. The unit has dimensions of 60 mm width, 44 mm depth, and 250 mm height.

Design and Operating Principle

The ventilator comprises an indoor unit with a decorative front panel, a fan unit, a heat exchanger unit inside the air duct, and an outer ventilation hood. In VENTO inHOME Wi-Fi mini models, the fan and heat exchanger are combined in a single cartridge. Two filters inside the air duct provide coarse air purification. A window on the front panel houses the IR remote control receiver and a light sensor that adjusts LED brightness.

Diagram Description (Ventilator Design):

• Outer ventilation hood: Prevents ingress of water and foreign objects.
• Cartridge: Combines fan and regenerator for airflow and heat recovery.
• Regenerator unit: Provides heat recovery.
• Ventilation unit: Generates airflow.
• Sound-absorbing material: Reduces noise.
• Air duct: Plastic duct.
• Back part of the indoor unit: Contains circuit board and control units; allows air duct shut-off for downtime.
• Front part of the indoor unit: Decorative face panel.

Operating Principle of Shutters

Models with automatic shutters open during operation and close for 2 minutes upon shutdown. The process takes up to five minutes. A shutter lock (item 1) keeps shutters open during power failure. Manual closing is possible by pressing push rod (item 2). A shutter position sensor ensures correct operation upon power restoration. The mechanism has a 1-5 minute delay. VENTO inHOME Wi-Fi M models lack shutters; airflow is blocked by pushing the front panel.

Diagram Description (Shutters): Shows shutters in open and closed positions, and manual operation (push rod item 2).

Opening/closing the airflow: Gently pull the front panel to open the air duct and start the fan. Gently press down on the front panel to close the air duct and stop the fan.

Ventilator Operation Modes

• Ventilation: Runs in air exhaust or supply mode at set speed. In a network, modes can be mixed based on DIP switch No. 3.
• Air supply: Operates in supply mode regardless of DIP switch No. 3.
• Boost: Runs at maximum speed.
• Regeneration: Operates in two 70-second cycles for heat and humidity regeneration. Cycle I extracts warm air, absorbing heat/humidity. Cycle II supplies fresh air, absorbing accumulated moisture and heating it. If two ventilators are used, they operate with opposite rotation directions.

The ventilators can connect to humidity sensors, external relay sensors (normally open contact), or 0-10V analogue sensors. Triggering these sensors switches the unit to Boost mode. The Boost mode switch-off delay timer starts when sensors return to original position.

Mobile App Configuration: The Blauberg Home mobile app allows configuring humidity/analogue/relay sensors, Boost mode delay (30 min default), Night mode (8 hrs default), and Party mode (4 hrs default). A weekly schedule can be set for different speeds by day/time. In case of conflicting modes, priority is: Night/Party timer > Standby > Boost > Weekly Schedule > Standard operation.

Mounting and Set-up

READ THE USER'S MANUAL BEFORE INSTALLING THE UNIT.

WARNING: DO NOT BLOCK THE AIR DUCT WITH DUST ACCUMULATING MATERIALS (CURTAINS, CLOTH SHUTTERS, ETC.) AS IT PREVENTS AIR CIRCULATION.

Connection to Power Mains

The ventilator connects to single-phase AC 100-240 V/50 (60) Hz power mains. Use insulated, flexible conductors (0.5-0.75 mm² for power, 0.25 mm² for sensors). Use copper wires for all connections. Connect via the terminal block on the controller board. Connect through an external automatic switch with magnetic trip. Tripping current should be based on fan casing label. The design allows connection of external controls with normally opened (NO) contacts (e.g., CO2 sensor, humidity sensor, switch). When NO contact closes, the unit switches to maximum speed. An analogue sensor with 0-10 V output is also compatible.

Diagram Description (External Connections Diagram): Shows the wiring for power input (100-240V), NO contact of external device, and analogue sensor connection (0-10V) to terminals XT1, XT2, XT3 on the controller board.

Timers can be adjusted via the mobile app. Pressing a speed key or timer button again deactivates the timer.

Ventilation Unit Operation with Mobile Application

Download and install the Blauberg Home application from the App Store or Play Market. The ventilator acts as a Wi-Fi access point (default name FAN: + ID, password 11111111). The app allows configuring the ventilator for connection via your home Wi-Fi network or a cloud server.

Controlling the Ventilator Using the Smart Home System

Connect ventilators to the Smart Home system according to the user manual for Smart Home system connection.

Wireless Connection of Several Ventilators

Ventilators can be combined into groups with one master and multiple slave units. The master unit is controlled via mobile device, remote, or buttons. Control signals are transmitted to slaves. In master mode, the unit receives sensor signals (humidity, discrete, 0-10V) and switches modes. Slave units only receive signals from the master and ignore others. If master connection is lost for over 20 seconds, slaves switch to Standby mode.

Sensor-based operation: Ventilators respond to sensor signals only when acting as a master. If any sensor is triggered, all ventilators in the group reach maximum speed.

Diagram Description (Ventilator Wireless Connection Diagrams):

• Wiring diagram 1: Shows connection of up to 8 slave units or mobile devices to a master unit with its own Wi-Fi access point. A mobile device may not connect if 8 slave units are connected.
• Wiring diagram 2: Shows master, slave units, and mobile devices connected to a Wi-Fi router access point. The number of slave units is limited by router capacity. An extra access point can be used if needed. Multiple master units can be connected for zone control.

Recovery Setup Mode

Use recovery Setup mode to restore access if Wi-Fi or master ventilator passwords are lost. To enter, press and hold the Ventilation button on the ventilator casing for 5 seconds until beep and LED blinking. The mode lasts 3 minutes. To exit immediately, press and hold the Ventilation button again for 5 seconds.

Available settings in this mode for the master ventilator:

• Wi-Fi name: Setup mode.
• Wi-Fi password: 11111111.
• Unit password is ignored.

IMPORTANT: Ensure all slave ventilators are within Wi-Fi coverage of the master when setting up. Reconnect slaves after changing master Wi-Fi parameters.

Connecting Master and Slave Ventilators

1. Set DIP switches on each ventilator according to its role (master/slave).
2. Configure master ventilator Wi-Fi settings via the Blauberg Home mobile app.
3. Set the master to special mode (all LEDs flash). Repeat for slave ventilators until they beep and LEDs stop flashing. Switch master back to normal mode.
4. Note: For multiple Wi-Fi access points, connect master to the first AP, then slaves. Connect master to the second AP, then the second group of slaves.
