Ventilation levels

The ventilation levels can be set manually with the RLS 1 WR control unit. LEDs indicate the selected ventilation level, a pending filter change or faults.

In ventilation level II (nominal ventilation), the ventilation unit switches to the Auto sensor operating mode (setting can be changed by the installer). The automatic system ensures hygienically perfect ventilation based on the determined humidity values (combination sensor) and/or air quality values (optional CO2/VOC sensor).

Ventilation levels I-III: Shift up with the button, shift down with the button.

• Ventilation level I, ventilation for humidity protection (building protection): LED I flashes. Interval ventilation 13 minutes on – 17 minutes off – 13 minutes on.
• Ventilation level I, reduced ventilation: LED I on. Continuous operation.
• Ventilation level II, nominal ventilation: LED II on. Continuous operation. Ventilation unit in Auto sensor operating mode.
• Ventilation level III, intermittent ventilation: LED III flashes. Intensive ventilation with timer. Once a timer interval has elapsed, the ventilation unit switches back to nominal ventilation
• Ventilation level III, intensive ventilation: LED III on. Continuous operation.
• Filter change indicator: LED II flashes.
• Fault display: All 3 LEDs flash on the RLS 1 WR. The fault elimination must be acknowledged manually. Press both arrow keys at the same time for 3 seconds.
  RLS T2 WS: The fault is displayed. Acknowledge fault clearance on the display.
  RLS G1 WS: The status LED lights up red. Press both ventilation level keys at the same time for 3 seconds.
