FAN COILS
MAXinBOX FC 0-10V FAN incorporates
two independent fan coil
functions that
implement all the logic involved in the control of up to two fan coil units.
ETS PARAMETERISATION
After enabling “
Fan Coils
” in the General screen (see section 2.1), a new tab will be
incorporated into the tree on the left.
Figure 8
Fan Coils - Configuration.
The two fan coil functions can be activated independently by marking their checkboxes.
This brings some more tabs to the tree.

FAN COIL x
Each fan coil function requires setting some general parameters and, optionally, some
advanced parameters. All of them are described next.
2.5.1.1
GENERAL
Among other options regarding the fan coil operation modes and the values and delays
involved in the opening and closing of the valves, the general parameters bring the
option to set two offsets:
The
minimum value of the control variable
that should activate the fan, i.e.,
the minimum percentage value that will be required to make the actuator
actually operate the fan; values under that minimum will be ignored by the
actuator. This is called “Offset 1” in Figure 9.
The
minimum fan speed
, i.e., the minimum voltage (in percentage) that
permits appreciating motion in the fan. This parameter is useful when the fan
