USE (OMNIA ULI C)

COMMANDS:
Ventilation is only allowed when the fins are open; if necessary, open them manually.
Closing the fins switches off ventilation although the electronic thermostat remains
active and continually records ambient data to ensure a prompt restart if the fins are
opened again.
STARTING
OFF The fan coil is switched off.
It may however start again in Heat mode (anti-freeze function) if the room temperature
falls below 7°C and the water temperature is suitable; in this case the red LED flashes.
To start the fan coil, turn the knob towards the functioning mode required in the AUTO
position or in one of the three ventilation speeds.

SELECTING THE SPEED

AUTO The thermostat maintains the set temperature by changing the fan speed in
Automatic Mode in accordance with the room temperature and the set temperature.
V1 In this position, the minimum ventilation speed stays active regardless of thermostat
requests.
V2 In this position, the minimum ventilation speed stays active regardless of thermostat
requests.
V3 In this position, the minimum ventilation speed stays active regardless of thermostat
requests.

ILLUMINATED DISPLAYS

The LED (C) changes colour to indicate the functioning mode
that is active:
RED On indicates Heat operation
(heating).
Flashing indicates anti-freeze mode.
BLUE On indicates Cool operation
(cooling).
FUCHSIA Flashing: Indicates that there is a permanent inverter
alarm.
12
The LED (D) indicates a request from the electronic thermostat
for ventilation:
YELLOW On Indicates that the thermostat has detected a
room temperature that requires ventilation to be
started; if this does not occur, it means that the
water circulating in the system has not yet reached a
suitable temperature for enabling ventilation.
Off Indicates that the fins are closed and the fan
cannot start.
If the fin is open, led (D) Off Indicates that the ther-
mostat is in stand-by (selector switch A is in position
OFF) or that the thermostat does not require the fan
to operate.
Flashing indicates a functioning fault of the ambient
probe (Emergency Mode).
