5. SETTINGS
4 settings that can be changed using a fl athead 3 mm screwdriver:
Time 2
Time 2:
delay when contact of the D1-D2 output comes back (ventilation
control). Adjustable to 10 sec / 10 min / 15 min / 30 min and 60 min.
To set to 10 minutes.
Time 1:
delay in the L' output (illumination control). Adjustable to 5 sec / 5
min / 10 min and 20 min. Set to preference according to need.
Lux:
brightness threshold. Infl uence on the L' output. Adjustable from 10
to 2000 lux.
Metres:
detection sensitivity. If there is an AJUST'AIR OPTIC application, set
this potentiometer to the maximum value "+" to optimise the best
detection area.
CAUTION!
If an "AJUST'AIR OPTIC-V" system is in use, in the settings "2 speed single-pha-
se fan by capacitor": the L' output is used for the PV / GV switching of the fan.
Therefore:
• Set "Time 1" to 10 minutes.
• So that the brightness threshold does not affect how the system runs, set
"Lux" to the maximum value = 2000.
• CPTA-E: the sensor must be attached to the output labelled "SENSOR A" on
the POWER SUPPLY UNIT (the SENSOR B output should not be used).
6. MAINTENANCE
Before starting any maintenance operations, don't forget to unplug the device
from the mains.
This product requires regular cleaning (at least once a year) to avoid dust build-
up around the lens taking care not to scratch it.
