RLS 1 WR control unit
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 (combi 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 preservation). 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. |
Operating modes with RLS 1 WR as a solo control unit
Manual, Auto sensor or Off
Auto sensor function only active
- with nominal ventilation (ventilation level II),
- if external sensors are connected or
- Combi-sensor operation parameter is set to linear.
Off function can be deactivated with Single control unit Blocking off parameter (single control unit = RLS 1 WR control unit).
Operating modes when using several RLS 1 WR/EnOcean pushbuttons or in combinations with a touchscreen control unit
Manual, Auto time, Auto sensor, ECO mode supply air, ECO mode exhaust air or Off
- The operating mode is preset via the touchscreen control unit, APP or the web tool.
- Ventilation level adjustment is possible for a limited period of time.
- Off function can be deactivated with Single control unit Blocking off parameter (single control unit = RLS 1 WR control unit).
