Description

UNIVERSAL

EFFICIENT

USER-FRIENDLY

Many units can be connected to one network.

The ventilator can operate in a passive supply mode: the air shutters are open providing a natural air flow.

The design of the unit allows easy maintenance of the ventilator.

The humidity threshold in the room can be controlled by choosing one of three modes on the remote control.

Night mode
The ventilator switches to the first speed in the dark time of the day.

Easy mounting of the mounting plate by means of magnets.

EASY CONTROL

The TwinFresh Comfo series ventilators are equipped with a remote control.

Operation modes:

- Night mode

The integrated light sensor sends a signal to switch the ventilator to low speed mode.

- Speed switching

- Passive air supply

In this mode the shutters are open, but the fan does not operate.

- Air supply

In this mode all ventilators will operate in supply mode irrespective of the maximum air supply setting.

- Ventilation

All the ventilators in the network operate in permanent air extract or air supply mode. To ensure balanced ventilation at the stage of installation it is advisable to set one half of the ventilators to air supply mode and the other part of the ventilators to air extract mode.

- Ventilation with heat recovery

- Humidity control mode selection

To provide centralised control all ventilators should be connected to one network.
However, only Master responds to the signals from the control panel,
the remote control, and the humidity sensor.

ADVANTAGES

	Simple mounting – you need only to mount it, plug into a socket and use!		High efficiency – up to 90%.
	The unit properly operates at temperatures up to -20 °C (-30 °C if it is equipped with a ventilation hood for cold climate).		Integrated humidity sensor for the automated unit operation.
	Many units can be connected to one network by control cables.		Control is provided by the remote control or buttons on the casing.
	Automatic drafts shutoff when the ventilator is off.		Noise level is from 13 up to 34 dBA.
	Ventilation of premises with the area of about 40 m² (the area is approximate and depends on the ventilation standards in your country).		F8 filter of high filtration efficiency can additionally purify supply air.
