1.8 Storage / Warehousing
Please keep the unit dry and dust-free in protected spaces.
When storing for a prolonged time the following steps should be taken to avoid damaging influences: Protection
by dry, air-dustproof packing (plastic bags with drying agent and moisture indicators). The storage place must
be waterproof, vibration-free, and free of excessive temperature variations. Damages due to improper
transportation, storage or commissioning must be verified and are not liable for warranty.
1.9 Functional description
The MultiPlexBox is used for the individual ventilation control of connected zones for example: (apartment,
office, commercial unit) in combination with a central ventilation system. The unit consists of a supply air
chamber and an extract air chamber (see figure 1). The chambers are equipped with a measuring orifice and
a volume flow control damper. The volume flow control dampers can be controlled separately. Large sound
insulation elements ensure quiet operation. The MultiPlexBox can be controlled via the ECO element controller
(Ref no. 90001253) or the Touch Element controller (Ref no.
90001254) A sensor for Humidity (Ref no.
90001248) and a sensor for Humidity and VOCs (Ref no. 90001249) are available for demand-controlled,
automatic operation.

1.10 Fireplaces
The relevant applicable rules for the joint operation of fireplaces, ventilation, extraction hoods and other
devices must be observed, as well as general building law and regulation requirements. Airflow Developments
cannot be held responsible for negligent installation which is done without following proper guidelines.
Supply and extract ventilation systems may only be operated with room air-dependent fireplaces if the flue gas
evacuation is monitored by special safety devices (on site) and it is ensured that the supply and extract air flow
is interrupted in the event of tripping. It is recommended to speak with the responsible chimney sweep to take
into consideration any requests before procuring an under-pressure monitoring system for fireplaces. Please
see the below warning before installation and operation of the unit:
WARNING:
Danger to life due to electric shock. An electric shock can result in death or
severe injuries. Before working on the unit, disconnect the unit from the mains power
supply! The use of an external contact as a shutdown method for under pressure
monitoring is not permissible!
