TROUBLESHOOTING GUIDE
Problem
Solution
Heater stays ON all the time
at night.
Cover PIR lens with a thick cloth. If the light turns out, check detection area for heat
or reflective source. If the light stays on, check wiring. See Section 3.
PIR keeps activating for no
reason (at random).
Turn the unit off at the isolation switch. Turn the unit back on again after 30 seconds.
Leave for approximately 18 minutes. If heater
activates, check area for false
activation from heat, wind or reflective source.
PIR sensor will not operate at
all.
Check that the power is switched ON at the isolation switch. Turn OFF the power to
the unit and check the wiring connections. Check the heater/lamp. If the heater/lamp
has failed, replace. Please note that the unit will not detect through glass.(e.g. in a
glazed porch).
The PIR sensor will
not
operate at night.
The level of ambient light in the area may be too bright to allow operation at the
current
DUSK setting. During the hours
of darkness, adjust the DUSK control slowly
clockwise until the heater/lamp illuminates. Refer to previous section for more details.
Unit activates during the
daytime,
Adjust the setting anti-clockwise to lower the level of ambient light required for
activation.
PIR
coverage
is
poor/
sporadic.
Unit may be poorly located. See previous section -
‘Selecting The Location’ and re-
locate the unit.
Detection range varies from
day to day.
PIR sensors are influenced by climatic conditions. The colder the ambient
temperature, the more effective the sensor will be. You may need to make seasonal
adjustments to the sensor head position to ensure trouble-free operation all year
round.
