MASTER-SLAVE connection
The unit's board allows the sharing with other units of control signals coming from a single control by means of the

The Master unit receives signals from the remote control and sends them to the Slave units which will have the same
settings:
-On\Off
-Operation mode
-Fan speed
-Set Point temperature

-Sleep mode activation
For the connection it is necessary to operate on the unit's control board . The connection between different units
is done using bipolar cables . Make sure to keep the polarities A and B indicated on the terminal block CN5 (fig .6) .
Up to 32 units can be connected .
