USE (OMNIA UL C)
CONTROLS:
Ventilation can only take place with the louvers open.
These must be opened manually.
When the louvers are closed, ventilation is shut down (the thermostat howe-
ver remains operative, continually detecting room conditions for prompt
restart when the louvers are reopened).
On / Off
OFF
The fancoil is off.
The unit will restart in heating mode (anti-freeze function) if room temperatu-
re drops below 7°C and water temperature is suitable; in this case, the red
LED lamp will flash.
To restart the fancoil, rotate the knob to the operation mode required in
AUTO position or in one of the three fan speeds.
Speed selection
AUTO The thermostat maintains the temperature of the setting by adjusting
fan speed in automatic mode, according to the room temperature and the
temperature setting.
The thermostat maintains the temperature of the setting by on-off
cycles, using minimum, medium and maximum fan speeds as
required.
Temperature selection
Use to make the required temperature setting.
The temperature at the central position will depend on the current operating
mode (Heating 20°C, Cooling 25°C).
The maximum temperature deviations from the central position are +8°C and
-8°C .
Season change
The OMNIA UL C automatically sets to Heating or Cooling mode according to
the temperature of the water circulating through the unit; season change can
be made by adjusting the temperature selector switch.
DISPLAYS
The LED indicator lamp C indicates the current operating mode:
ROSSO On: unit in heating mode.
Flashing: unit in anti-freeze mode.
BLU
On: unit in cooling mode.
FUCSIA
Flashing: water in unit has not yet reached tempera-
ture required to enable ventilation.
LED D: a ventilation request has been made by the electronic
thermostat:
YELLOW
On: the thermostat has detected a room tempera-
ture that requires enabling of ventilation (if fan ope-
ration is not enabled, the water circulating in the unit
has not yet reached the required temperature).
Off: louvers are closed and fan operation is disa-
bled.
If the louvers are open and the LED D is off, the ther-
mostat is on stand-by (selector A has been set to
OFF) or the temperature does not require enabling of
the ventilation function.
Flashing: an ambient probe operating fault has
been detected (Emergency mode).
