7.2. DESCRIPTION
·The main module is the central element of the VMX system, and
indispensable for its operation.
·Centralises all the bus information.
·The only powered element in the VMX system. It supplies power and
information to all the other elements in the system.
·It has a mode selector button (“full or little”, or proportional)
·It has a jumper to operate in "full or little" mode (100% - 10%) or "full
or none" (100% - 0%)
·It indicates the number of modules connected to the system.
·It detects and signals failures and short circuits in the system.
·The main module must be accompanied by the transformer specified in
this document.
·One single module connected to the power supply.
·Add a C2 circuit breaker before the power input.

7.4. REDUCED FLOW MANAGEMENT
The minimum ventilation by default is never zero but equal
to 10% of the maximum rate of ventilation attainable (‘Full
or little” mode). It is however possible regulate the module
initially (before wiring) so that the minimum ventilation of
the system is zero ("full or none" mode). In any event and
before proceeding to release the blocks, always check that
the set-up complies with the regulations in force for the
premises in question. The release jumper can be reposi-
tioned subsequently at any moment. Memorisation at main
module level will then be required.

·10% of the maximum (‘Full or little”)
·Jumper not present: minimum ventilation reaches 0%
