INTRODUCTION
A variety of Zennio devices incorporate the
‘Analog’ Fan Coil control module
, which
enables the control external fan coil units where both the opening of the valves and the
fan speed can be controlled through
analog voltage outputs
.
The fan coil units to be controlled may be
two-pipe
or
four-pipe
. Each
pair of pipes
constitute a water circuit controlled by a
valve
, whose position is managed by a 0
– 10
VDC analogue signal.
Typically, the two water circuits of a four-pipe fan coil unit correspond to the
cooling
and
heating
functions, being therefore both modes available during the device operation.
The single water circuit of a two-pipe fan coil unit, on the other and, may be configured
for
cooling, heating or both.
Important: In order to confirm whether a particular device or application program
incorporates the fan coil analog function, please refer to the device user manual, as
there may be significant differences between the functionality of each Zennio device.
Moreover, to access the proper fan coil analog user manual, it is always recommended
to make use of the specific download links provided at the Zennio website
) within the section of the specific device being parameterised.
