1
VMX S-CO2 or VMX S-PRE sensors
2
Main module and other optional modules:
-
Relay OUT* if control of fan is on full or little (threshold)
-
or IN/OUT 0-10 V if control is proportional
3
Frequency (or voltage) regulator or power relay (if motor > 0.5 A at
maximum)
4
Fan
5
Diffuser
4.2. MULTIZONE
Under the so-called "Multizone" approach, several zones or rooms are
served by the same fan. Then there will be one VMX system per zone,
each with motorised valves connected to the fan. Each zone or room
will then need a main module (VMX Main) and one or more sensors.
Each main module may be supplemented where necessary with optional
modules (Contact IN, Relay OUT, IN/OUT 0-10V).
4.
UNIZONE OR MULTIZONE MANAGEMENT
The VMX system allows several ways of managing ventilation, in "Unizone" or in "Multizone".
4.1. UNIZONE
Under the "Unizone" approach, each zone has its own fan. This can be
controlled by one or more sensors associated with a main module and one
or more optional modules.
