Intended use

PP 45/PPB 30 units with heat recovery are used for air extraction/ventilation of apartments, offices and similar rooms. They are suitable for new buildings and renovation work. The units are designed for 24h operation. The housing unit’s ventilation system should be configured in accordance with DIN 1946-6.

PP 45 are ventilation units, which are generally only suitable for use in supply air rooms. To achieve efficient ventilation of these units, we would recommend operating the PP 45 in pairs, with alternating ventilation and air extraction.

PPB 30 are balanced ventilation units, which are the ideal choice for use in exhaust air rooms (bathroom, WC or kitchen with windows) and ventilate and extract air from the rooms at the same time. Exhaust air mode is started automatically depending on the setting or can be started manually at the touch of a button. PPB 30 are stand-alone units or can be used in groups with other PPB 30/PP 45 units.

PPB 30 units have degree of protection IP X4. The protection zone must be determined depending on the unit variant used. PP 45 are installed in exterior walls (with a wall thickness of 265-790 mm), PPB 30 in exterior walls (with a wall thickness of 320-790 mm). The electrical connection is made to a permanent electrical installation.

The ventilation units are operated using a room air control suited to the unit type:

• RLS 45 O or RLS 45 K for PP 45 O / PP 45 K and PPB 30 O / PPB 30 K .
• Radio switch DS 45 RC for PP 45 RC / PPB 30 RC. Alternatively, with RLS 45 K + PP 45 EO radio extension module.

PP 45/PPB 30 units are only intended for domestic use and similar purposes. No other or additional use is intended.
