VENTILATOR OPERATION MODES
Ventilation: the ventilator operates in the permanent air supply or air extract mode at set speed.
Regeneration: the ventilator operates in reversible mode with heat and humidity regeneration in two cycles.
Air supply (available from a mobile device only for DVC 10-50W(L)). All the connected ventilators in the network switch to the air supply mode.
In Regeneration mode each operation cycle lasts 70 seconds.
Cycle I.
Warm stale air is extracted from the room. As it flows through the regenerator, it heats and moisturizes the regenerator, transferring up to 97 % heat
energy.
In 70 seconds as the ceramic regenerator gets warmed the unit is switched to the air supply mode.
Cycle II.
Fresh intake air from outside flows through the ceramic regenerator and absorbs accumulated moisture and heat up to the room temperature.
In 70 seconds after cooling of the ceramic regenerator the unit is switched to the air extract mode and the cycle is renewed.
Shutters are closed. Shutters are open. The indoor unit is equipped with air shutters.
During the unit operation the shutters open to let the air stream flow
freely though the unit.
After the unit shutdown the shutters close within 2 minutes.

WIRELESS CONNECTION OF SEVERAL VENTILATORS
The unit operates in two modes:
Master. The unit acts as a leading unit in the network. All the Slave unit and mobile devices are connected to the Master unit via Wi-Fi. The Master unit
is operated by means of a mobile device, the remote control or the touch buttons on the unit casing. The control signal is automatically transferred to
the connected Slave units. In this mode the unit responds to a signal from sensors, as a humidity sensor, an external digital sensor, an external analogue
sensor 0-10 V and changes its operation mode respectively.
Slave. The unit acts as a driven unit in the network. The Slave unit responds to a signal from the Master unit only. Any other signals from other controls
are ignored. In this mode the ventilators ignore any other signals from the sensors. In case of communication loss with the Master unit above 10 seconds
the unit is turned off.
There are two wireless connection options:
1. Connection of up to 4 Slave units or mobile devices to the Master unit
with its own wireless access point.
In case of connection of four Slave units to the Master unit with its own
wireless access point a mobile device may not be connected.
2. The Master units, the Slave units and the mobile devices are connected
to a wireless access point of the Wi-Fi router.
In this case the Master unit is able to operate 32 Slave units.
Please note that the Wi-Fi routers may have individual limitations for the
maximum number of connected devices.
