USE OF THE KEY SELECTOR (WHEN PRESENT):
It is used to interact directly with the electric board, giving the choice of 3 differ-
ent functioning modalities:
AUTO = The timer is executing the programs which have been preset for the
selected zone
OFF =
The timer is excluded and, for the selected zone, the security setpoint
rt is maintained (if enabled)
ON =
The timer is excluded and, for the selected zone the setpoint SP1 is
maintained
ELECTRICAL CONNECTIONS PROBES: Avoid to cross the cables, separating
the very low tension connections from the network connections. The cable for the
connection of a probe must have a section lot lower than 0,5 mm
2
and its length
is limited to 10 m. In case of connections longer than 10 m it is recommended the
use of shielded cable, taking care to connect the shielding to the common con-
nection of the inlet of the probe of thermostat or of the remote control.
