1 CONSTRUCTIVE FEATURES
WH high wall mounted fan coils, proposed in three models with cooling
capacities ranging from 2 to 4.28 kW, make the ideal indoor unit for air
conditioning systems in public buildings, shops and hotels.
Coupled with Galletti water chillers and heat pumps, they provide an
environmentally friendly alternative to direct expansion systems.
WH fan coils are hallmarked by the quality of their components and their
versatility of use:
> High efficiency heat exchanger made with copper piping and
aluminium fins, low pressure drop on the water side.
The heat exchanger comes complete with manual air valves and
hoses for connection to the system or to the rear valve-fitted panel
(optional accessory).
> Extremely quiet tangential fan connected to a 3-speed electric motor
with a low number of revolutions.
> Motorised air outlet buffle for adjusting the direction of the airflow
from the fan coil.
> The high quality plastics used allow operation with hot water up to
a temperature of 75°.
> Microprocessor controlled operation with control of air intake
temperature and that of the water inside the heat exchanger that
regulates the heating function according to the temperature of the
water (from 38°C to 75°C).
The auto restart function makes it possible
to automatically restore unit management
after blackouts.
> Infra-red remote control that when
combined with the microprocessor control
allows simple, versatile management of
the fan coil:
- temperature setting
- manual or automatic fan speed
selection
- manual or automatic operating
mode selection
- cooling
- ventilation
- heating
- automatic air outlet buffle
oscillation with position control
- night mode setting
- Automatic 24-hour on-off timer
- Clock
- LCD for displaying all fan coil functions
The remote control comes packed separately, complete with wall bracket.
> Pilot lights on the front panel indicate unit operation.
> Air filter easily extractable for cleaning.

3 REMOTE CONTROL FUNCTION
REMOTE CONTROL FUNCTIONS
- If the room temperature is lower than the setting temperature, the
heating mode is activated. The motor driven valve is triggered. The
internal fan works at the set speed.
- If the room temperature is equal to the setting temperature + 0.5°C,
the heating mode is stopped. The motor driven valve and the internal
fan are disconnected.
- The setting temperature range is 15° - 30°C.The internal fan speed can
be set on Min, Med, Max and Auto.
- The motor driven valve will be activated/deactivated after a delay time of
30 sec
- If the water temperature is equal to 38°C, the motor driven valve is
activated and the internal fan is deactivated.
- If the water temperature is >38°C the motor driven valve is activated. The
internal fan will continue working at the set speed.
- If the water temperature is >75°C the motor driven valve is deactivated.
The internal fan will continue working at the set speed.
COOLING
- If the room temperature is higher than the set temperature, the cooling
mode is activated. The motor driven valve is activated. The internal fan
works at the set speed.
- If the room temperature is equal to the setting temperature -0.5°C, the
cooling mode is stopped. The motor driven valve is deactivated. The
internal fan works at the set speed.
- The setting temperature range is 15° - 30°C.
- The internal fan speed can be set on Min, Med, Max and Auto.
- The motor driven valve will be activated/deactivated after a delay time of
30 sec.
- If the water temperature is equal to or lower than 2°C, the motor driven
valve is deactivated and the internal fan continues working at the set
speed.
TIMER
- The switch off timer can be set only when the system is ON.
- The switch on timer can be set only when the system is OFF.
- The maximum setting time is 24 hours.
- Switching the unit on/off will cancel the timer mode.
