where:
sm = extra-low speed
1 = low speed
2 = medium speed
3 = maximum speed
COOLING
HEATING
N.B.: in case of 4-speed confi guration and valve, ventilation
in heating mode is shifted by 0.5°C to permit a natural
convection phase
■ Speed disabled: Can be selected only in heating mode
and with 4-speed confi guration only. The indoor unit oper-
ates by natural convection only.
Extra low speed: can be selected only with

N.B.: In the case of fi xed speed, the fan on/off logic will be
equivalent to the automatic logic.
WATER CONTROL
The ventilation operation depends on the system water
temperature control. Based on the operation mode, different
heating or cooling thresholds will be enabled.

NO
Upon a call of the thermostat, the absence of the enabling
signal will be indicated on the display by the fl ashing of the
symbol representing the active mode (
The enabling signal is ignored:
■ if the water sensor is not included (P04 = 0) or in alarm
status because disconnected
■ in the cooling mode with 4-pipe confi gurations

LOGICS
:
FORCED OVERRIDES
The normal fan operating logic will be ignored in particular
override situations that may be necessary to ensure correct
control of the temperature or the unit's operation. This may
occur:
in the cooling mode:
■ on-board controller (P01 = 0) and confi gurations with valve:
■ on-board controller and valveless confi gurations: every
Air temp.
In the heating mode
■ while the electrical heater is on: the fan is forced to run at
■ once the electrical heater has gone off: a 2 minute post-
Air temp.
DISPLAY
The display shows the fan status
■ On fl ashing: fan in standby mode
■ On steadily lit: fan on
■ OFF: fan disabled to operate by natural convection only
and fan speed (with indication of "automatic" logic if proper)
enabled or selected (in case of stand-by fan)

rotation is carried out at medium speed to enable the air
sensor to read the room temperature more accurately.

ventilation cycle will be run at medium speed. (N.B.: this
cycle will be completed even if the thermostat is switched
off or in the event of a changeover to the cooling mode)
