Additional valve 6 ways
The additional valve also manages commands for 6-
way valves in which the control value from 0% to
100% defines both the percentage of valve opening
and the passage of hot or cold fluid.

Value to be sent to bring both the cold and hot valves to
the fully closed position. [area of the diagram between B
and C]
For the additional valve, in 6-way mode, it is
possible to define different control differentials
around the setpoint value as shown below:
This makes it possible to adjust the opening and
closing of the additional valve independently of the
speed control (for example, once the setpoint has
been exceeded, a maintenance action can be taken
keeping the valve open again without activating the
speeds)

Force fan coil speed
In fan coil operation (in 1-bit or 1-byte mode), you
can force the use of just one speed and bypass the
automatic speed selection. This mode is useful, for
example, in small rooms such as hotel rooms, for
example or in any case where the fan speed may
bring noise. To activate forcing, you must act on the
1-bit object that selects AUTO / MAN and then on
the object that activates the desired speed (3x1 1-
bit object or 1 object at 1-byte in% mode)
Ventilation mode
When using fan coil, you can also activate "fan" or
"ventilation" mode. In this mode, the fan coil will
never turn off the fan even when, after reaching the
100%
