Smart Web/Easy connection
The Smart Web/Easy must be connected by using the connec-
tor provided. Connect the power supply, making sure polarity
is correct.
Connect the RS485 network to its terminals, making sure po-
larity is correct.
For multiple heaters, connect terminals D+ and D-, making sure
polarity is correct; the network can be made both as a serial
and star network.
NOTE: THE correct address for each PCB must then be
set up. Addresses must start from 1 to N without inter-
ruptions 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 Smart
Web/Easy, please read the operating manual supplied
with the accessory.
Summer ventilation
To enable the fans only (summer ventilation with burner off),
three types of controls are available:
•
the ID3-IDC2 contact;
•
with Smart Web/Easy;
•
manual control with the LDC control on board of the machine.
NOTE: Before switching off the blowers, the heater carries
out the post-ventilation cycle.
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°=

; 6°=

.
Therefore, to program address 13, you must set to ON
switches 4°+3°+1°; the matching address will be

=13.
When an address is changed, the PCB must be powered off
and on again.
