ECO mode
The fan rotation speed (or the delivery air flow if the constant
flow option is present) stays constant as the thermal load
varies and is shutdown when setpoint is fulfilled.
To further increase the energy savings in this condition, it is
also possible to set less demanding operation setpoints for the
unit in respect to the standard mode.
This function is indicated for the thermal maintenance of the
served area in case it is temporarily not used, which can for
example occur at night.
The ECO mode can be activated:
 manually: from keyboard with MODE menu
