Comando Amico Remoto

: the boiler is set-up

for the application of the Comando Amico Re-

moto remote control

(CAR

) or of the Mini

CRD, which must be connected to clamps 40

and 41, by observing polarity and eliminating

jumper X40.
Room thermostat: the boiler is set-up for the

application of the Room Thermostat (S20) which

must be connected to clamps 40 and 41 and by

eliminating jumper X40.

NOTE:

the user interface is on the welding side

of the boiler board.
