4. Functions
This sensor is a motion switch, which turns on the light on detection of people movement, and turns off
after a pre-selected hold-time when there is no people around. A daylight sensor is also built-in to prevent
the light switching on when there is sufficient natural light.
4.1 On/off Control
Designed in the software, sensor switches on/off the load right at the zero-cross point, to ensure the
in-rush current is minimised, enabling the maximum lifetime of the relay.
4.2 Zero-cross relay operation
The motion sensor is employed, but only activated on the manual press of the push switch,
light remains keeps on in the presence, switches off automatically in the long absence.
4.3 Semi-auto Function (Absence Detection)
HMW20-20181218-A1
Note: this function can be chosen by remote controller only, please refer to detailed explanations
in part 7.
With the help of push-switch, this sensor maybe over-ridden by the end-users to switch on/off
the lights manually. This makes the product more user-friendly and offers more options to fit for
extra ordinary demands.
* Push: on/off function;
ON

OFF: the light turns off immediately and cannot be lightened for a certain time (equals to
hold time preset) even movement is detected. After this period, the sensor goes back to auto
sensor mode.

ON: the light turns on and goes to auto sensor mode.
