Intended use

Use these ventilation units and room air control systems for their intended purpose in accordance with the relevant operating, assembly and installation/commissioning instructions. The unit is only permitted for use indoors in accordance with the specified environmental conditions.

PP 45/RV 2 ventilation units are only suitable for supply air rooms. The unit must not be operated in exhaust air rooms (bathrooms, kitchens, toilets or similar rooms).

PPB 30 ventilation units are primarily used in exhaust air rooms. For installations in rooms where fresh air enters (bedrooms, etc.), we recommend informing the homeowner about the continuous, extremely quiet change of direction of rotation, as this may be perceived as a nuisance. Alternatively, the sleep mode with ventilation level 0 can be used at night.
