OPERATING MODES
MANUAL
The choice between the HEATING or the COOLING mode is carried out
manually
by the keypad, the room thermostat or the remote
selector (see the chapter ELECTRICAL CONNECTIONS).
AUTOMATIC
The choice between the HEATING or the COOLING mode is carried out
automatically
by the electronic module, according to the
room temperature detected by the probe placed on the unit inlet (or on the room thermostat, if present). When temperatures are higher
than the cool set, the unit cools the room; when temperatures are lower than the heat set, it heats the room.
The choice between the automatic and manual change is definite by the parameter num. 1 OnModeMan:
MANUAL
= 1 AUTOMATIC
= 0
ECO
In this operating mode, lower consumption is preferred to comfort:
The ECO-COOL set is higher than the COOLING set
The ECO-HEAT set is lower that the HEATING set
In this mode, the fan is activated periodically to verify the room temperature and therefore decide to activate or not the available re-
sources to satisfy the set.
It can be activated by the keypad.
CLEAN
The CLEAN mode differs from the VENTILATION ONLY because it can be timed; after the set time, the mode deactivates.
It can be activated by the keypad.
VENTILATION
In VENTILATION ONLY, the unit behaves like a fan: the OUTLET fans are activated and no setting on the room temperature is per-
formed.
It can be activated by the remote selector.
SET-POINT
MANUAL SET POINT
The ambient set point can be MANUALLY modified by the thermostat at P01 parameter
HID-P1 ROOM THERMOSTAT
The unit is designed for the connection with a remote HID-P1 thermostat to be placed in the room.
It is possible to perform the thermoregulation according to the temperature detected by the probe of the room thermostat: it is neces-
sary to take away the probe placed on the unit inlet and to modify the machine configuration (this operation should be performed by an
authorized service centre).
The thermostat displays the set-point on the display.
