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 a semi-automatic air damper that closes during shutdown of the ventilator and prevents air backdraft.
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.
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
When either of these devices is triggered, the ventilator switches to maximum speed
sensor returns to its original position, the Boost mode deactivation delay timer is started.
In the relevant sections of the Vents 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;
Boost mode
• set the turn-off delay time (default setting is 30 minutes);
• set the duration of the first speed timer
• set the duration of operation by timer of the third speed
