Confi guration procedure
Confi guration can be performed on both
the system interface and the boiler display
alike.
- Power up the module.
- The display screen shows:
Error 430 "function not defi ned"
- Access the technical menu until the dis-
play shows:
"Enter code".
- Turn the knob to enter the technical code
(234) then press OK and enter the com-
plete menu.
- Select the parameter:
1100 "select function", then set the con-

ZONE 2
In this mode the device powers outputs
OUT1, OUT2, OUT3 when a request for heat
occurs in zone 1, zone 2 or zone 3 respec-
tively.
Requests for heat can be generated by a
BUS device, by a room thermostat con-
nected to the boiler or by a room thermo-
stat directly connected to one of the inputs
on the board (IN1, IN2, IN3).
Up to 3 direct zones can be controlled by
connecting one or more pumps or zone
valves to outputs OUT1, OUT2, OUT3.
Moreover, outputs OUT1, OUT2, OUT3 are
activated in the event of:
- anti-frost function in progress inside the
boiler

- anti-seize procedure
(30 seconds for every 24 h of inactivity)
Conversely, outputs OUT1, OUT2, OUT3 are
deactivated in the event of:
- errors occurring inside the boiler (includ-
ing low pressure error 108)

In this mode the device has two separate
functions:
1) error notifi cation
BOILER
If errors occur inside the boiler (resettable
or non-resettable), the device powers up
output OUT1 (230 V).
This makes it possible to provide a remote
error indication by means of a light or
sound signal.
Note: if you wish to use a device with a
clean contact input, it can be connected in
accordance with the following connection
