Installation
Mechanical Structure & Dimensions
- Ceiling (drill hole φ66~68mm)
- Carefully prise off the cable clamps.
- Make connections to the pluggable terminal blocks.
- Insert plug connectors and secure using the provided cable clamps, then clip terminal covers to the base.
- Clip fascia to body.
- Bend back springs and insert into ceiling
Wiring Diagram
Note:
- We recommend the mounting distance between sensor to sensor should be more than 2m to prevent sensors from false-triggering.
- The face-to-face installation between sensors and sensors or other radio sources is not recommended, or false trigger issue will potentially behave.Make sure the installed environment is free of any obvious vibration, strong air blows, curtain swing, water flow in pipe ……The recommended mounting distance between sensor to sensor is >3m to prevent sensors from false-triggering and furtherly adjust per actual environment.
Functions
On/off Control
This sensor is a motion switch, which turns on the light upon detection of motion or breathing, and turns off after a pre-selected hold-time when there is no movement or breathing. A daylight sensor is also built in to prevent the light from switching on when there is sufficient natural light
Lux Off Function
The built-in photodiode will also automatically turn off the light when the ambient natural light exceeds the programmed lux level for more than 5min, regardless of whether motion is detected or not.
Manual Override
With the help of push-switch, this sensor can be over-ridden by the end-user to manually switch on/off the light, which makes the product more user- friendly and offers more options to fit some extra-ordinary demands:
- Short Push (<1s): on/off function;
On → Off: the light turns off immediately and cannot be triggered ON by motion until the expiration of pre-set hold-time. After this period, the sensor goes back to normal sensor mode.
Off → On: the light turns on and goes to sensor mode, no matter if ambient Lux level exceeds the daylight threshold or not.
Note: if end-user do not want this manual override function, just leave the “push” terminal unconnected to any wire.
Semi-auto Mode (Absence Detection)
It is easy to forget to switch off the light, in office, corridor, even at
home. And in many other cases, people do not want to have a sensor to switch
on the light automatically, for example, when people just quickly pass-by,
there is no need to have the light on. The solution is to apply this “absence
detector”: motion sensor is employed, but only activated on the manual press
of the push-switch, the light keeps being ON in the presence, and switches off
in the long absence.
Note: end-user can choose either function 3.3 or function 3.4 for application.
Default function is manual override.
Zero-cross Relay Operation
Designed in the software, sensor switches on/off the load right at the zero- cross point, to ensure that the in-rush current is minimised, enabling the maximum lifetime of the relay.
Wire Preparation
Pluggable screw terminal. It is recommended to make connections to the terminal before fitting to the sensor

Detection Pattern & Optional Accessories
When it’s in breathing & true presence detection mode and in sitting situation, facing to sensor directly will have a better detection range than 90 degrees side facing to sensor.
Optional Accessory — Ceiling/Surface Mount Box: HA03
Big and small silicon gasket used to make IP54 degree protection when
HMW28/PRO device mounted into HA03 housing for ceiling mount
Small silicon water-proof gasket dimension(size:mm)
Big silicon water-proof gasket dimension(size:mm)
Optional Accessory — HA08
*Note: Optional Accessory HA03 & HA08 can not be uesd together.
