2.10 SETTING AUTOMATIC COOLING/HEATING MODE
Setting this type of adjustment enables the control to automatically select cooling
or heating mode, excluding normal manual selection. This adjustment is particularly
suitable for 4-pipe appliances, and can be activated solely by a qualified and
authorised installer. To activate this function, hold down the cooling/heating
selection key (fig. 7 ref. B) for 10 seconds until the blue and red symbols light up
simultaneously (fig. 7 ref. C and D). This setting is also maintained in the event
of a power failure.
To deactivate the automatic cooling/heating function, press the cooling/heating
selection key again for 10 seconds. Then check that each time the key is pressed it
is possible to cycle through cooling only (blue indicator fig. 7 ref. C on), heating only
(red indicator fig. 7 ref. D on) or ventilation mode (blue and red indicators both off).
3 USE
The command makes the temperature regulation completely autonomous through
the AUTO, SILENT, NIGHT and MAX programmes, with a probe positioned in the
lower part of the ventil radiator/fan coil, and guarantees anti-freeze security even
when in stand-by.

3.1 SWITCHING ON/OFF
If there is a master switch on the mains power supply then it must be switched on.
To switch on the fan coil unit, press key (fig. 6 ref. H) for 2 seconds.
To switch off the appliance hold down key ) (fig. 6 ref. H) for around 2 seconds.
No light signal means the unit is in ‘stand-by’ mode (not running).
When the control is in this operating mode, protection against freezing is guaranteed.
If the ambient temperature drops below 5°C the hot water solenoid is activated and
the fan motor runs at minimum speed (AF).
3.2 MANUAL COOLING/HEATING SELECTION
Press key ((fig. 6 ref. B) for 2 seconds to select the cooling (blue LED), heating
(red LED) or ventilation (red LED and blue LED off) modes in sequence.
In ventilation mode both the hot water and the cold water solenoid valves remain
disabled, while the fan activates at the set speed.
Manual cooling/heating/ventilation mode selection is not available if the automatic
cooling/heating mode has already been set by the installer. This function is signalled
by the blue and red LEDs coming on alternately each time the key is pressed
(fig. 6 ref. B).
The capacity of the appliance to operate in cooling or heating mode is always
subject to the temperature of the water circulating inside the circuit. If the water
temperature does not reach a suitable value for the mode set (i.e. if the water is
too hot in cooling mode or too cold in heating mode), the fan motor stays off and
the current indicator light - blue for the cooling mode, or red for the heating mode
(fig. 6 ref. C) – will blink.
3.3 SETTING THE TEMPERATURE
The ambient temperature required can be set using the relevant selector (fig. 6
ref. A). The minimum temperature that can be set is 15°C, while the maximum
temperature that can be set is 30°C.
3.4 SETTING AUTOMATIC RUNNING MODE
To select this mode, press key (fig. 6 ref. H) until the indicator light comes
on (fig. 6 ref. E). In this mode the microprocessor system automatically adapts
the operation of the unit to the changes in the room conditions. In particular, the
fan speeds adjusts automatically between the minimum and maximum values,
depending on the heating or cooling requirements of the room.
In appliances fitted with radiant plate and in heating mode, when the ambient
temperature comes close to the required value, the fan deactivates and the
system controls the ambient temperature using only the radiant effect and natural
convection.
3.5 MAXIMUM SPEED MODE
To select this mode, press key until the indicator light comes on (fig. 6, rif.
D). This mode immediately gives the maximum power available in both cooling and
heating modes (the fan motor always runs at maximum power). Once the required
ambient temperature has been reached, a different operating mode should be
selected to obtain the optimum setting in terms of heat and noise.
3.6 SILENT-RUNNING FUNCTION
To select this mode, press key ) (fig. 6 ref. H) until the indicator light comes
on (fig. 6, ref. F). In this mode the fan speed is always set to the minimum value to
provide the most silent running in any operating mode.
3.7 NIGHT-TIME FUNCTION
To select this mode, press key (fig. 6 ref. H) until the indicator light
comes on (fig. 6, ref. G). In this mode the fan speed is kept at a low value, and the
temperature is automatically set as follows:
• reduced by 1°C after one hour and by a further degree after 2 hours in heating
mode;
• increased by 1°C after one hour and by a further degree after 2 hours in
cooling mode.
On models equipped with radiant plate, the night-time function in heating mode
is carried out with the fan deactivated to heat rooms using radiation and natural
convection, as happens with traditional radiators.
3.8 LED INDICATORS
The red and blue LEDs (fig. 6 ref. C) indicate whether the unit is running in heating
or cooling mode. When the LEDs are off, the appliance is set in ventilation mode
(both hot and cold water valves are not activated). If either of the two LEDs flashes,
this means that the water demand (hot or cold) is not satisfied and so the fan shuts
down until the water temperature reaches a suitable value to satisfy the demand.
When the red and blue LEDs (fig. 6 ref. C) come on alternately, this indicates
that the automatic cooling/heating mode is on.
The 4 LEDs , , e (fig. 6) indicate the running mode set, and they are all
off in Stand-by mode. Each of these LEDs start blinking (soft-blinking) if in heating
or cooling modes (red or blue LEDs on) the temperature set is respectively lower
or higher than the room temperature detected by the appliance.
The brightness of the LEDs on the electronic panel is reduced after 15 seconds
of inactivity on the keys or temperature selector for increased comfort at night.
3.9 ERROR SIGNALS
FI: The fan coil unit requires maintenance, select the stand-by program, clean
the air filter as described in the maintenance manual, and the next time the unit
is switched on, hold down keys (fig. 6 ref. B and H) for 5 seconds until
normal operation is resumed.
E2: signals that the ambient temperature probe is faulty.
E3 is associated with the water probe fault.
E4 signals a fault with the motor or the speed sensor. In the second case the
appliance runs normally but the fan speed modulation function is inhibited; pressing
keys (fig. 6 ref. B and H) for 10 seconds will cancel the alarm signal.
3.10 SHUT-DOWN FOR LONG PERIODS
When switching off for long periods or holidays, proceed as follows:
• Deactivate the appliance
• Set the master switch to OFF.
The anti-freeze function is not active.
