If BCM is coupled with HSCP or UFly,
you must edit the following parame-
ters (Chap.3.1)
By connecting a storage tank sensor, Stemp ACC,
the 803 Srv parameter automatically takes on the
value 27 and the system reconguration is request-
ed on the User Interface (eectively saving the new
conguration).
It is necessary to save the new system congura-
tion in the User Interface devices menu (*)
(*) Ref. to User Interface manual
To enable the request, close the contact
between pin 12 and pin 9 with a jumper.
Also jump pin 12 and 11 (INAIL input
alarm) or use it to manage the system's
safety devices. With an open contact, all
generators are switched o with the alarm
signal.
