Removable system
The central unit is made up of a base for the connection to the system bus cable and a
removable front cover with batteries. The system so formed lets the user perform the
programming operations and replace the batteries easily.
Conguration
Dierently from the 99 zone version, the 4 zone ush mounted central unit must
be congured. This central unit is tted with an integrated temperature probe, and
therefore it must be congured. The conguration sockets on the back of the central unit
are in fact intended and reserved for the integrated probe. They are: ZA, ZB and SLA.
The ZA and ZB sockets must always be used for the conguration operations, connecting
two congurators that identify the address, and the number of the zone controlled by
the probe itself. It is not necessary to start with zone 01, although it is fundamental
that the values of the subsequent zones are immediately after those of the central unit
itself. The conguration procedure requires the completing of the operations using the
“Conguration” menu of the central unit, and the activation of the “Learning” function.
In fact, the search within the system is performed on 3 zone addresses that follow the
one assigned to the central unit itself. The actuators controlled by the probes must be
congured with the same zone address.
