FAN COIL
MAXinBOX FC 0-10V VALVE incorporates
one fan coil
module that implements all the
logic involved in the control of a two-pipe or four-pipe fan coil unit where the fan speed
can be switched through
relay outputs
and the opening and closing of the pipe valves
can be commanded through
a 0 to 10 VDC signal
(depending on the required degree
of opening).
ETS PARAMETERISATION
After enabling “
Fan Coil
” in the General screen (see section 2.1), a new tab will be
incorporated into the tree on the left.
The fan coil module requires setting some general parameters and some specific
parameters related with the valves and the fan. All of them are described next.
2.5.1
CONFIGURATION
The general configuration of the Fan Coil module entails, on the first hand, setting
whether the fan coil is composed of either:
Four pipes (two valves)
.
Two pipes (one valve)
,
Every two pipes
make up a circuit where the water flow is controlled by means of a
valve
, whose position is managed through an analogue 0 to 10 volt DC signal.
Typically, the two water circuits of a
four-pipe fan coil unit
correspond to the
cooling
and
heating
functions (and to the cooling and heating valves, respectively), being
therefore both modes available during the device operation.
On the other hand, the single water circuit of a
two-pipe fan coil unit
may be
configured for:
Cooling
Heating
Cooling and Heating.
