SENSOR ITEM L/N/NT4692
Technical
features
The device can adjust the room temperature according to the daily routines
in both winter and summer, varying the settings locally with respect to those
received from the control unit.
The item has a knob for the local temperature selection (limited to ± 3°C
with respect to the value set by the control unit), the antifrost mode and
the OFF mode. There are two LED, one green and one yellow, on the front
of the item. The green LED indicates that the device is working correctly and
the activation of the antifrost mode and OFF of the corresponding area. The
yellow LED indicates the actuator state and any faults.
The modes are managed according to the criteria listed below.
LEGEND
1) Knob: for manual temperature setting (± 3°C), to select the antifrost/thermal
protection (❆) mode and the OFF state (forced zone off).
2) green LED: when it shines steadily it indicates that the device is active, when
it flashes it indicates that the OFF or antifrost modes are set locally.
3) yellow LED: when it shines steadily or it is OFF it signals the state of the
devices in the corresponding zone, when it flashes it signals a fault.

BUS
This mode has the maximum priority, whether selected by the sensor or set
by the control unit; to quit the OFF mode use the device which set it.
OFF MODE
In this position if the Temperature control system is set as heating the sensor
works in antifrost mode; if it is set as cooling it works as thermal protection.
The sensor can also work in collaboration with other sensors in “slave”
confi guration to allow the Control unit to calculate an average of the
temperature over several measuring points. This function is useful for
managing very large rooms, inside which the temperature can vary
appreciably.
If there is a fault on the control unit, the sensor works with the last settings
received, thus continuously maintaining the last temperature determined
with summer or winter setting.
If the sensor selects the OFF mode this has priority even if the control unit is
faulty, thus the zone controlled by the sensor will remain OFF.
The sensor is made in two fl ush-mounted modules in the LIVING
INTERNATIONAL, LIGHT and LIGHT TECH series and can control a zone with
a maximum of 9 actuators of the same type, 9 slave sensors and 2 pumps
(one for the heating system and one for the cooling).
