Device and Operating Principle

The ventilator consists of an indoor unit with a decorative front panel, a cartridge, an air duct with sound insulation, and an external ventilation hood.

The core component is the cartridge, which includes the fan, regenerator, and two filters for air purification and protection of the regenerator and fan.

The indoor unit features protective louvers that close when the unit is off to prevent drafts.

The Vento Expert Duo model includes airflow dividers, and its external hood is designed to direct supply and exhaust air in different directions.

The external ventilation hood prevents direct ingress of water and large objects into the ventilator.

Diagrams illustrate:

• External ventilation hood: Prevents water and foreign objects entry.
• Sound insulation: Reduces operating noise.
• VENTO Expert Cartridge: Contains fan, filters, and regenerator for airflow and heat regeneration.
• Indoor unit rear: Contains control board and main control devices.
• Airflow dividers (VENTO Expert Duo): Separate supply and exhaust air streams.
• Air duct: Plastic air channel.
• VENTO Expert Duo Cartridge: Contains fans and regenerators.
• Filters: Purify air and prevent regenerator contamination.
• Indoor unit front panel: Decorative function, can close the air channel during long downtimes.
• VENTO Expert Duo front panel: Filters air.

Operating Modes

The manual describes the operating modes for both VENTO Expert and VENTO Expert Duo:

• Ventilation: The unit extracts or supplies air at a selected speed. In group operation, units can alternate between supply and extraction based on DIP switch settings.
• Regeneration: The unit operates in a reversible mode with heat and moisture regeneration. Stale, warm air is extracted and passes through a ceramic regenerator, which heats up and humidifies. After 70 seconds, the unit switches to supply mode, blowing fresh, cold air through the now warm regenerator. This cycle repeats. In group operation, units work in противофазе (out of phase).
• Boost: The unit switches to maximum speed without changing the operating mode. This can be triggered by humidity sensors or external devices.

Sensors and Connectivity:

• The ventilators are equipped with a humidity sensor and terminals for connecting external analog (0-10V) and digital (normally open contact) sensors.
• When triggered, these sensors activate the Boost mode.
• The Vents Home mobile application allows configuration of sensor operation, thresholds, Boost mode delay, and scheduling of different operating speeds.

Priority of Modes:

1. Night mode or Party mode timer.
2. Standby.
3. Boost.
4. Weekly schedule.
5. Standard mode.

Installation and Preparation

General Installation Steps:

1. Prepare a through round opening in the external wall. The required opening size is indicated in the diagrams.
2. Install the air duct in the wall, using foam wedges for easier mounting. The duct should protrude from the outer wall by a distance 'A' for the external hood installation. Ensure the air duct is sloped downwards towards the outside by at least 3 mm.
3. From the inside, attach the cardboard template from the kit to the wall using adhesive tape. Align the large opening in the template with the air duct. Use a spirit level for horizontal alignment. Mark holes for dowels and drill them. Route the power cable through the designated opening.
4. Separate the front part of the indoor unit from the rear by pressing the side latches.
5. Secure the rear part of the indoor unit to the wall using screws from the mounting kit. Remove two self-tapping screws from the left transparent cover to access the connection terminals.
6. Route the power cable and connect the ventilator according to the external connection diagram. Secure the cables with the clamping strip. Reinstall the transparent cover.
7. Insert the cartridge into the air duct, ensuring the mark points upwards. Secure the wire with the clamping strip and connect the connector to the board.
8. Install the front part of the indoor unit.
9. Insert the sound insulation into the air duct by rolling it into a cylinder with the protective paper facing outwards. Insert the cylinder into the duct until it reaches the cartridge. Mark the end of the duct on the roll, remove, and trim the excess insulation. Install the fitted insulation into the duct.
10. For Vento Expert Duo, install sectional airflow dividers from the outside, inserting them into the duct until they reach the cartridge. Mark the last divider, remove, and trim it. Install the fitted dividers into the duct.
11. Install the external ventilation hood. Refer to the separate manual for hood installation.

Important Notes:

• Do not block the air duct with materials that accumulate dust (e.g., curtains) as this will disrupt airflow.
• For Vento Expert models, ensure the thermal actuator rod is fully lowered before attaching the front panel. A flashing white LED indicates the actuator is not lowered.

Electrical Connection
