If the contact interface is used in conjunction with the temperature control system to
optimise energy saving, two dierent types of congurations will be possible:
- Use in the temperature control system only: The contact interface is directly connected
to the temperature control BUS It autonomously and independently manages
the contact line. Follow by connecting the AUX congurator to the MOD sockets.
Then congure the Z and N sockets, in order to assign the address from 1 to 99 to
the device within the system. The coupling between the interface contact line and
the temperature control zone must be performed using the TiThermo application.
For more information refer to the MY HOME Temperature control guide.
- Use of a burglar-alarm system integrated with the Temperature control system: in this
case, the contact interface is connected to the burglar-alarm system BUS only, and
communicates with the temperature control system BUS through the F422 interface.
The interface must be congured in Z and N following the requirements and features of
the burglar-alarm system; only congurators with values 4 to 7 must be connected to
the MOD position, corresponding to the management of NC contacts with generation
of AUX event (see tables above). Also in this case, the actual coupling between the
interface contact line and the temperature control zone must be performed using the
TiThermo application. For more information refer to the MY HOME Temperature control
guide.

Note (*): Follows the delay set on the central unit:
this function is operative only with central units with display. With ush mounted 3
module central units, the interface must be allocated to ZONE 1, with a time delay set
(see central unit conguration).
Note (**): pulses generated by the sensor depending on the degree of opening of the
window, in cm, before the alarm is generated.
