VASCO DX4 E heat recovery unit (400 m3/h) with WiFi control as standard.

Maximum efficiency of 400 m3/h (pressure drop 100Pa). Heat recovery efficiency of 89%. Automatic airflow control for maintaining constant balance (Constant Flow), counterflow cross exchanger, modulated summer bypass, ISO ePM1 55% air filter for supply air.

Powder-coated steel casing, entire internal structure made of EPP (expanded polypropylene: strength, insulation, vibration/noise damping), top and bottom internal connections, possibility of vertical or horizontal installation (wall mounting). Recommended use of dedicated pre-heater PTC (11VE44150).

Installation connections diameter 200 mm.

The included equipment of the heat recovery unit includes the Vasco Wi-Fi gateway (11FH30008), which allows the user to control ventilation via smartphone from anywhere in the world after connecting to the home internet router and installing the VASCO CLIMATE CONTROL app on a mobile device (Android, iOS).

The VASCO CLIMATE CONTROL app includes: a weekly programmer for 5 ventilation intensity levels, the ability to make current gear changes and start the "fireplace" program (temporarily increased supply air level). The app provides a view of current temperatures in the heat recovery unit and the status of the summer bypass, pre-heater, and frost protection. The app also allows modification of the heat recovery unit settings.

The included gateway requires pairing with the heat recovery unit after connecting to the internet router.

Also included in the heat recovery unit equipment is a wireless RF switch (11VE20012), which allows selection of 3 ventilation intensity levels and activation of the timed ventilation function. The LED indicator of the switch confirms proper operation, indicates errors, and indicates the need to replace filters. The RF switch allows setting the nominal performance (at maximum speed). The supplied wireless switch is paired with the heat recovery unit.

The heat recovery system control allows for the use of optional room sensors: carbon dioxide CO2 sensor 11VE20013 (installed in the living room) and humidity sensor 11VE20014 (in the bathroom). After wireless pairing of the sensors with the heat recovery unit, it is possible to select program "A" - automatic ventilation intensity regulation based on actual current needs. When equipped with optional sensors, the heat recovery unit achieves the highest energy efficiency class.
