ADVANCED FUNCTIONS
1.- REMOTE ON/OFF
This function allows you to turn the unit on/off by a simply remote contact (contacts 95-96 in ECOLEAN and AIRCOOLAIR
units;contacts 88-89 in AIRCUBE units).
Close contact = ON; Open contact = OFF.
2.- REMOTE CHANGEOVER WINTER/SUMMER
On heat pump units (also in Aircoolair cooling only + electrical heater), cooling or heating mode can be selected by a remote con-
tact (contacts 97-98).
Close contact = Cooling.; Open contact = Heating.
To activate this function set parameter
H06=1.
3.- DYNAMIC SET POINT
With this function, which needs to incorporate an additional outdoor temperature probe, it’s possible to adjust the set point
dynamically based on ambient temperature.
The set point value can be increased or decreased when the external conditions are more advantageous, thus achieving extra
energy saving.
Dynamic set point must be activated in the factory.
The user must set the parameters as shown in the graphics below:

AIRCOOAIR
WARNING
On Aircoolair units, remote changeover doesn’t work if the automatic mode has been selected by DC40.
