FUNCTIONING
The same FCL unit can be coupled to
several grid accessories that determine
different functioning modes.
The particular information is supplied
in the manuals supplied with the
accessories. The features are recalled
here that differentiate the different flow
and intake grid units.

- Functioning in cooling mode: using the
remote control it is possible to set the
cooling mode and the room temperature
desired by the user (set). If the fan speed
is set in automatic mode, the control
board will select the fan speed and
decide on the opening of the water valve
depending on the difference between
room temperature set by the user (set)
and the temperature detected by the
room probe. In the case, with 4 -pipe
system, in cooling mode, the control
board will pilot the cold solenoid valve
while the hot solenoid valve is closed.
- Functioning in heating mode: using the
remote control it is possible to set the
heating mode and the room temperature
desired by the user (set). If the fan speed
is set in automatic mode, the control
board will select the fan speed and
decide on the opening of the water valve
depending on the difference between
room temperature set by the user
(set) and the temperature detected by
the room probe. In the case of 2-pipe
systems, in heating mode, the control
board will pilot the standard solenoid
valve. In the case, with 4 -pipe system, in
heating mode, the control board will pilot
the hot water solenoid valve (accessory),
while the cold solenoid valve is closed.
- AUTO functioning (Automatic): by
activating "AUTO" mode on the remote
control, the room temperature is
decided by the control board, which will
also select the fan speed (functions in
Automatic). The thermostat reads the
room probe SA (always continuous even
in heating mode even if thermostat is
enabled) and decides whether to function
in heating, cooling or dehumidification
mode. From the remote control it is
possible to correct the work set by the
control board by ± 5°C. The unit will
automatically re-select the functioning
after every start-up from stand-by.
- Heating mode functioning with electric
resistance: if the unit foresees an electric
resistance, the only fan functioning
speeds allowed will be maximum (V3)

If an electronic control panel is to be
installed, check that the Dip Switch
settings inside the panel correspond to
system requirements, otherwise modify
the setting as indicated in the instructions
attached to the control panel.

and medium (V2), the minimum speed
(V1) will be activated automatically
only in the post heating phase. Using
the dip-switches it is determined in the
installation phase whether the electric
resistance is active in integration or
replacement.
Heating functioning mode with resistance
in integration: the resistance is activated
at the same time as the hot water valve
in order to increase unit efficiency.
Alternatively, if the temperature of the
water is insufficient, the resistance is
activated to make up for the insufficiency
of the yield supplied by the coil to the
water. Ventilation starts-up later with
respect to the resistance (preheating).
Heating functioning mode with resistance
in replacement: the resistance is
activated only if the temperature of the
water is insufficient. Ventilation starts-
up later with respect to the resistance
(preheating).
- Water probe upstream from the valve:
the probe detects the temperature of the
water in the system.
- Continuous ventilation (in cooling and
heating modes): ventilation is always
active, the thermostat only controls the
water valves and the electric resistance.
- Thermostat ventilation (heating):
ventilation starts later than the
thermostat call in order to allow the hot
water to run inside the coil (preheating).
- Functioning in dehumidification mode:
requests that cold water circulates in the
system. The ventilation speed is always
minimum. It is possible to correct the
work speed, fixed by the control board,
by ±5°C from the remote control.
- Functioning with timer: allows to
program the delay on switch on or switch
off from 0.5 up to 12 hours. A power cut
causes timer settings to be zeroed.
- Full Power functioning: ventilation
is forced at maximum speed, the set
temperatures are 32°C in heating mode
and 18°C in cooling mode.
- Stop due to power cut: after a power

cut, the unit re-starts with the settings
activated before shutdown, only the
timer is reset.
- Delayed start-up: the unit can start up
ventilation later with respect to switch-
on, normally up to 2'40" but in particular
conditions the stand-by time may be
extended.
- SW4 probe: the installation of a probe
for the detection of the temperature of
the water that circulates in the system is
envisioned as an optional.
- Emergency control: if necessary, the
"AUX" key is available on the receiver
grid, which activates the "Auto-
Emergency" mode. In this mode, the unit
functions in automatic, depending on
the room temperature read when the
"AUX" key is pressed. If Auto-Emergency
functioning mode is selected, timer
functioning is excluded. Pressing of the
"AUX" button is indicated by an acoustic
signal. Switch-off takes place by the same
"AUX" key.
