Wall Mounte Heat Recovery Ventilator Operating Modes
The ventilator has three ventilation modes:
Natural air supply
– the ventilator is used for natural ventilation, the fan is not activated
Supply
– the ventilator supplies fresh air to the premise regardless of CN jumper position.
Ventilation
– the ventilator operates in permanent supply or extract mode at set speed depending on remote controller.
Regeneration
– the ventilator operates in reversible mode with heat and humidity regeneration.
In Regneration mode the ventilator operates in two cycles, 65 seconds each.
Cycle 1.
Warm stale air is extracted from the room. As it flows throgh the regenerator, it heats and moisturizes the regenerator, transferring up to 90% heat energy. In 65 seconds as the ceramic regenerator gets warmed the ventilator is switched to supply mode.
Cycle 2.
Fresh intake air from outside flows through the ceramic regenerator and absorbs accumulated moisture and heats up to the room temperature. In 65 seconds as the ceramic regenerator gets cooled down, the ventilator is switched into extract mode and the cycle is renewed.
Humidity mode is available in Regeneration mode
Low humidity: setting humidity threshold at 50%
Middle humidity: setting humidity threshold at 60%
High humidity: setting humidity threshold at 70%
Here is the manual control at the side of fan body.
