Below is a description of all the operating modes available on MasterAria.
The device can in any case be reconfi gured by the manufacturer of the
cooling/heating system or the installer (based on the features of the
system), and therefore some functions may be not available.
2.2 Operating modes
Cooling
Once having switched the device on, by pressing the ON/OFF button:
Repeatedly press the MODE button until the cooling symbol
•
(snowfl ake) comes on.
Set the set point (desired temperature) using the UP & DOWN
•
buttons.
Repeatedly press the fan button to select the desired fan speed; if AUTO
•
mode is selected, the speed is decided by the electronic controller
based on the deviation from the set point (the greater the deviation,
the higher the speed).
If the COOL ENABLE function is active, the fan is started only if the coil
temperature is low enough, to avoid undesired fl ows of hot air. If this
condition is not satisfi ed, the cooling symbol (snowfl ake) fl ashes.
