Application examples
Example 1: Single-room application with a PP 45 unit pair
Recommendation: Operate PP 45 devices in pairs.
Example 2: Combination of PPB 30 K + PP 45 units
1 | PP 45 unit with alternating operation for continuous ventilation of living spaces |
2 | PPB 30 K unit with balanced operation for continuous ventilation in the bathroom |
3 | Room air control RLS 45 K |
| Supply air and exhaust air with change of direction |
| Outside air and outgoing air with change of direction |
Ventilation solution for a 3-room flat with PPB 30 K ventilation units for the bathroom and PP 45 ventilation units for living spaces. The PPB 30 K ventilates and extracts air from the bathroom, at the same time, with balanced operation. A PPB 30 K fan ventilates the room with air which has been pre-warmed in the heat exchanger. The other PPB 30 K fan transfers the thermal energy from the exhaust air to the heat exchanger during air extraction. Every 60 seconds, the air direction changes, thereby permitting a ventilation mode with constant heat recovery. In case of high air humidity, intensive ventilation can be activated via a humidity sensor (automatically) or manually with a button. Pure exhaust air mode is also possible and here the two fans pump humidity out of the room (no heat recovery).
