Manual exhaust air mode

For PPB 30 O

Both fans of the PPB 30 unit run at full load = air extraction at a total of 45 m³/h without heat recovery.

The following applies to RLS 45 O + PPB 30 O: Exhaust air mode is only released when using one individual PPB 30 O in combination with an RLS 45 O controller (unit type setting = PPB 30 and number of units = 1). In this case, there is no volumetric flow compensation. Air extraction in compliance with the relevant standards can thereby be ensured in a bathroom, for example.

This mode is switched on manually by pressing the “Ventilation level” key on the RLS 45 O for more than 2 seconds. Exhaust air mode usually lasts 10 minutes.
