STANDARD DISPLAY VIEW

At start-up, the user terminal shows “NFC” for a few moments, indicating the availability of connection via NFC for communication with mobile devices; after which, if nothing

is connected via NFC, the display switches to the standard display view.

The standard display view shows:

— in the top line: the water ow temperature;

— in the bottom line, when the unit is switched on, the water return temperature; when the unit is switched o, the status “OFF”.

 Note: during “Bluetooth” communication, “bLE” ashes on the display.

SYNOPTIC

From the main menu, press the key to access information on device status and temperature, overheating, etc., of the two circuits:

— unit “OFF” and the cause of switch-o:

“diSP” from keyboard;

“dI” from remote contact (via digital input);

“Schd” from time slot (scheduler);

“bMS” from BMS;

"ChnG" from functioning mode change (heating/cooling);

"AlrM" from alarm.

— “CMP” compressors;

— "AFC1" water ow temperature source circuit 1;

— "AFC2" water ow temperature source circuit 2;

— "EuP1" evaporation temperature circuit 1;

— "SSH1" overheating circuit 1;

— "Cnd1" condensation temperature circuit 1;

— "dSt1" BLDC compressor discharge temperature circuit 1;

— "EuP2" evaporation temperature circuit 2;

— "SSH2" overheating circuit 2;

— "Cnd2" condensation temperature circuit 2;

— "dSt2" BLDC compressor discharge temperature circuit 2;

and if the access level is “Service”:

— "Hd00" supervision address (BMS);

— "Hd01" baud rate BMS;

— "Hd02" BMS communication parameters;

— "ESC" to exit the synoptic.

3 OPERATING FUNCTIONS

DIRECT ACCESS FUNCTIONS

The user terminal is used to access only basic conguration parameters, such as direct commands and active alarms without a password; or, with a password, those dedicated

to unit conguration and optimisation.

Press the key

for 3 seconds to access direct access functions:

— set point;

— unit switch-on and switch-o;

— change of functioning mode (cooling/heating, only on reversible units);

— unit of measurement selection.

In “programming mode”, the bottom line indicates the parameter code and the top line the value.

Procedure

Push:
