Functions, settings

RV 2 ventilation units run in push-pull mode and ensure a continuous supply of fresh air with heat recovery in operation with heat recovery mode. The cross-ventilation operating mode (without heat recovery) ensures that the rooms are ventilated in one direction.

In push-pull operation, there is a constant change from the exhaust air phase to the supply air phase and vice versa every 30 seconds.

To reverse the direction, the fan unit in each ventilation unit is rotated in a drum. When the ventilation unit is switched off, the air path remains closed with the drum in the transverse position.

The setting values and system statuses are indicated on the RLS 45 K room air control by LEDs and symbols. To save energy, the LEDs of the RLS 45 K are dimmed if not used for 5 minutes. Set value can be changed with commissioning software.

The set operating mode and ventilation level apply to all connected room air controls and ventilation units, as does the External OFF function. Other settings (intermittent ventilation, sleep mode) only apply to ventilation units on the relevant room air control.

The cross-ventilation mode should only be used for limited periods so that the rooms do not cool down when the supply air temperature is low (outside temperature < 16 °C).
