Digital inputs
Digital inputs DI1 and DI2 have a fi xed confi guration, while the others can
be confi gured by parameter. The off status of digital input DI1 has priority
over any incoming serial communication signals, so that the user (directly
in contact with the fl ow of cold or hot air) can switch the MasterAria unit
off .
Input Description Ass. pars. Notes
DI1 ON/OFF input when the input is closed the unit is switched to OFF status (even when there is no network connection). When
switching OFF->ON, MasterAria is started however it can then be switched off from the terminal or via serial
connection. In OFF status, the valve is closed and the fan is off (after any extra fl ush cycles required for the heater)
DI2 cooling/heating Enabled when DIP2= ON
DI3 multifunction P43
DI4 multifunction P44
DI5 multifunction P45

(*) the “economy” function corresponds to the “sleep” function, however is activated by digital input.

Important: avoid parameter settings that create situations of
confl ict (for example, do not confi gure two digital inputs on the
same MasterAria as economy inputs).
Procedure for testing the installation
Once the installation has been completed, the test procedure can be run
to check the devices. The “acqua” terminal is required for these functions.
To enter test mode press the UP and DOWN buttons for 10 seconds with
the unit connected to the power supply and in OFF status; the event is
signalled by the buzzer, which emits a beep.
The test proceeds in steps, indicated on the terminal by the message “L”
followed by an incremental number; pressing the UP button proceeds to
the next step (signalled by the BEEPING of the buzzer). After the last step,
the procedure ends and the controller returns to normal operation.

“L09” fan started at minimum speed, no internal test
“L10” fan started at medium speed, no internal test
“L11” fan started at maximum speed, no internal test
“L12” output NO4 relay activated, voltage present (L). No internal test
“L13” output NO5 relay activated, voltage present (L). No internal test
“L14” output NO6 relay activated, contact closed. No internal test
“L15” output NO7 relay activated, contact closed. No internal test
During operation (and during the test procedure), the device may generate alarm signals, which are displayed on the terminal.
