To obtain a distributed ventilation system, a window-fitted ventilation unit (50) with i) an electronic circuit (90) with a microcontroller (91), ii) a fan (64) for transferring fresh air (20) from outer side (U) to inner side (S) as incoming air (21) iii) a fan (63) for transferring outgoing air (22) from inner side (S) to outer side (U) as waste air (23) is proposed. The microcontroller (91) comprises a register with status information of devices (50, 303, 304, 305) connected to the building ventilation system (200) and is configured to listen to the communication interface (93, 93', 95, 96, 94, 102, 103) for receiving status information, and to update the register upon receiving status information that is more actual than status information stored in the register. Also an independent claim for building ventilation system (200). |
