7.5. ASSEMBLY
·Install one main module per zone to be ventilated (one zone = one room)
·Mount the main module on a DIN rail in the power box
·Its width corresponds to two standard electrical modules
7.6. ELECTRICAL CONNECTION
Connect each module as indicated in the general wiring diagram. The modules were designed to be fixed on a DIN rail. They can be installed directly in a
power cabinet or in a separate power box. The boxes used must comply with regulations in force and have an IP protection index in accordance with their
place of installation.
12 VDC "In" terminal powered by a 230 VAC - 12 VDC transformer.
The main module should be connected to a power supply with appropriate EMC.
The power supply indicated in this document is highly recommended, as it has valid EMC.
Each Main module should have its own circuit breaker and be connected directly to the electrical switchboard especially with a
view to enabling maintenance operation.
A "Bus" terminal
supplies power and information to all the other elements in the system.
Maximum number of elements per main module:
1 x VMX S-CO2 sensor, 8 x VMX S-PRE sensors, 1 x In/Out 0-10 V Module, 2 x Contact In
Modules, 2 x Relay Out modules, 6 x motorised valves.
System electrical protection:
Add a C2 circuit breaker upstream the power input.
In case of a power cut, the configuration is saved in the main module.
7.7. POWERING UP THE SYSTEM
Connect the main module to a 12 VDC power supply following the diagram in the chapter relative to the electrical installation of the system and then
switch it on.
Characteristics of the transformer:
·Output voltage: 12 VDC
·Power: 30 W
·EN61558
To protect the circuit correctly, use one C2 circuit breaker and one transformer
per main module.

7.8. START-UP CYCLE
The flashing light indicates the launching of the start-up cycle. The flashing light can perform from
one to five cycles.
Once the start-up cycle has been completed, you can proceed to configure the system at the main
module level.
