Examples :
·If the Contact 1 cursor is in position 0 or 1 and the electrical circuit connected to the CTS1 terminals is closed (push button pressed or switch turned
off) then the instruction to cut ventilation off is sent: the VMX system cuts the ventilation off in the room immediately. If necessary, ventilation returns
10 minutes after the electrical circuit connected to the CTS1 terminal has been opened.
Instructions sent via a Contact IN module take priority and are immediate.
So this module can be used by an installer to test the installation.
·If the Contact 2 cursor is in position 4 or 5 and the electrical circuit connected to the CTS2 terminals is closed (push button pressed or switch turned
off) then the order to ventilate at 100% is given: The VMX system gradually returns to a target ventilation rate (via sensor or other means) 10 minutes
after the electrical circuit connected to the CTS2 terminals has once again been opened.
11.5. ASSEMBLY
It is designed to be mounted on a power box DIN rail. Its width corresponds to two standard electrical modules.
11.6. ELECTRICAL CONNECTION
Connect the module according to the wiring diagrams provided in this document.
Bus Terminal:
·it receives electrical power and exchanges information with all the other elements in the system.
·connected to the bus by two wires with section 1.5 or 2.5 mm² (flexible or rigid)
·
maximum number of Contact IN modules per main module: 2
CTS1, CTS2 Terminal:
·receives external information to start up or shut down ventilation immediately.

time
Measured requirement = 80 % but the system can only reduce the rate of ventilation a maximum of
10% per 10-minute period. This principle allows an unoccupied room to continue being ventilated for a
number of minutes (up to a maximum of one and a half hours) after the occupants have left, which
permits the decontamination of the room
