| RLS 45 O / RLS 45 K / DS 45 RC
Operation with heat recovery (HR)
Display via operating mode LED.
RLS 45 O / RLS 45 K : operating mode LED
PP 45 RC / PPB 30 RC : operating mode LED orange
Units switch between ventilation and air extraction at 60 second intervals. |
| RLS 45 O / RLS 45 K / DS 45 RC
Cross-ventilation without heat recovery (e.g. summer operation).
Display via operating mode LED.
RLS 45 O / RLS 45 K: operating mode LED
PP 45 RC / PPB 30 RC: operating mode LED blue
Ventilation units run with fixed direction of air flow in ventilation or air extraction mode. |
| RLS 45 K / DS 45 RC
Ventilation level 1 to 5.
Ventilation level 0 (ventilation Off) only possible if Off function is activated |
| RLS 45 O : Ventilation level 1 to 5.
Ventilation level 0 (ventilation Off) only possible if Off function is activated. |
| RLS 45 K / DS 45 RC
Intermittent ventilation with ventilation level 5.
Intermittent ventilation can be selected in heat recovery or cross-ventilation mode. With PPB 30 K / PPB 30 RC units, system operation can only be undertaken with basic settings. To switch on, press key for 2 seconds, the  LED flashes slowly. On RC units, the current operating mode LED flashes 2x, 5 times. Operating time of 30 minutes. The ventilation unit then switches back to the ventilation level previously used. To cancel, press a key. With the PPB 30 RC, the exhaust air mode is triggered via the touch of a button (blue operating mode LED 2x 2 seconds). |
| In the service menu of the PPB 30 RC, the intensive ventilation can also be configured instead of the exhaust air mode. Abort: Press a key. |
| RLS 45 K / DS 45 RC
Sleep mode with ventilation level 0.
Sleep mode can be selected in heat recovery or cross-ventilation mode. With PPB 30 K / PPB 30 RC units, system operation can only be undertaken with basic settings. To switch on, press key for 2 seconds, the LED flashes slowly.
On RC units, all 3 operating mode LEDs light up and then go out one after another. Operating time of 60 minutes. The ventilation unit then switches back to the ventilation level previously used. Abort: Press a key. |
| Intermittent ventilation, sleep mode or system Off can be activated on RLS 45 K controller with optional switches. When a function is switched on, the LED flashes slowly. |
| Optional button/switch for the PPB 30 K exhaust air or intensive ventilation mode.
If required, the PPB 30 unit can be switched to exhaust air mode (45 m³/h without heat recovery) or intensive ventilation mode (ventilation level 5 with heat recovery) using an optional button/switch. The commissioning software can be used to set parameters for how long these functions last and for the start delay for the switch. Once the time has elapsed, the ventilation unit switches back to the previously used ventilation level/operating mode. |
