The switches program the address by using a binary code; the corresponding values
are listed below: 1°=1; 2°=2; 3°=4; 4°=8; 5°=16; 6°=32.
Therefore, to program address 13, you must set to ON switches 4°+3°+1°; the
matching address will be 8+4+1=13.
When an address is changed, the PCB must be powered off and on again.

5.5.3. Connecting SmartEASY/WEB remote control
The SmartEASY/WEB must be connected by using the connector
provided. Connect the power supply, making sure polarity is
correct.
Connect the Modbus RS485 network to its terminals, making
sure polarity is correct.
In case of several boilers, the remote control must be electrically
connected to a single boiler and the D+ and D- terminals must
be connected making sure polarity is correct; the network can
be made both as a serial and star network.
N
ote: For multiple boiler cascading management in a single
zone, connect a single SmartEASY/WEB remote control.
Use shielded cable having a section equal to or greater than
0.4 sq.mm.
T
he correct address for each PCB must then be set up.
Addresses must start from 1 to N without interruptions in the
numbering sequence. The address of each PCB, if different from
zero, is displayed on the LCD as Axx, where xx is the address.
To program the SmartEASY/WEB, please read the operating
manual supplied with the accessory.
