ENGLISH
It is however possible to associate each channel to the desired
water zone in order to de
fi
ne which zone (1-2-3) each individual
REC, TA or CT is to control.
To associate the channels to the water zones, the jumpers
CH1
,
CH2
,
CH3
of connector
ST1
must be inserted following the dia-
gram and table below.

The position (not inserted, PIN 1-2, PIN 2-3) of the jumper assi-
gned to a channel cannot be replicated on the others. If more
than one channel is assigned to the same zone, the system goes
into stand-by blocking the outputs and signalling a fault (alarm
86 on the REC).

guration of the REC remote control on channel 1
When the
BAG
3
is con
fi
gured in
Link Mode
, a Family Remote
Control or REC 08 will also act as a remote control for the boiler if
it is connected on channel 1 (
CH1
).
THE
BAG

board must be appropriately con
fi
gured by insert-
ing the jumpers following the diagram and table below.

Please refer to the indications provided in the boiler manual
to correctly position the external sensor.
The external sensor is to be connected to terminals
36-37
of
connector
M12
of the
BAG
3
board using a bi-polar cable from
0.5 to 1 mm

.
IT is possible to select the zones in which the thermoregulation is
to be enabled by inserting the corresponding jumpers
ST3
,
ST4
,
ST5
on the board following the diagram and table below.

If the Family Remote Control or REC 08 is connected on channel
1 (CH1) the external sensor value displayed is updated every 5
minutes and shows an average of the readings taken. The value
in the start-up phase is the value acquired in real time.
To control the delivery temperature of the zones with a connect-
ed external sensor, please refer to the chapters “
Trimmer
” and
“
Temperature
” adjustment.
