Description

FUNCTIONAL

EFFICIENT

USER-FRIENDLY

Many units can be connected to one control network.

High heat recovery efficiency of up to 90 % is achieved due to the use of a cellular regenerator.

Unit design allows easy maintenance and mounting.

Noise-insulating material provides noise absorption during the operation of the ventilator.

One ventilator operating in heat recovery or ventilation mode is enough to ensure quality ventilation within a room.

The unit is controlled via a remote control and buttons on the control panel.

EASY CONTROL

The unit modes are controlled via the sensor control panel located on the casing of the unit or via the remote control.

Operation modes:

Speed setup
Operation mode setup

Ventilation
Regeneration

Timer setup

4 hours at speed III
8 hours at speed I

Operation modes:

ventilation with energy recovery
ventilation
speed switching and ventilator turning off

It is possible to control all the ventilators simultaneously by connecting them to a single network.
In this case, all ventilators (Slaves) will respond to a signal from the Master ventilator only.

ADVANTAGES

	Trendy ventilator design.		High efficiency – 90%.
	Can be mounted inside a prepared hole (from ∅170 mm) in a wall.		Humidity control with a humidity sensor.
	Connection of the units into one control network.		Connection of an external relay CO₂ sensor or other external relay sensors.
	Automatic drafts shutoff thanks to air damper when the ventilator is off.		Noise at the level of human whisper (from 1 up to 26 dBA at a distance of 3 m).
	Ventilation of premises with the area of about 25 m² (the area is approximate and depends on the ventilation standards in your country).		Simple mounting and maintenance.

SAVES ELECTRICAL ENERGY

To save energy, the ventilator operates in heat recovery mode with two cycles, which allows reducing load on air conditioning system during summer.

WHEN IT IS HOT OUTSIDE

RETAINS HEAT

In order to save heat within the room, the ventilator operates in the heat recovery mode with two cycles.
This allows preserving heat in the room and thus ensuring humidity balance and reducing load on heating system during winter.

WHEN IT IS COLD OUTSIDE
