Tri-level Control (Corridor Function)
2
Hytronik builds this function inside the motion sensor to achieve tri-level control, for some areas which require a light change notice
before switch-off. The sensor offers 3 levels of light: 100%-->dimmed light (natural light is insufficient) -->off; and 2 periods of
selectable waiting time: motion hold-time and stand-by period; Selectable daylight threshold and freedom of detection area.
Manual Override
3
* 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.
* Long Push (>1s): adjust the hold-time brightness level between10% and 100%.
Note: if end-user do not want this manual override function, just leave the “push” terminal unconnected to any wire.
With the help of push-switch, this sensor can be over-ridden by the end-user to manually switch on/off the light, or adjust the
brightness by push-switch, which makes the product more user-friendly and offers more options to fit some extra-ordinary demands:
Semi-auto Mode (Absence Detection)
4
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 dims down in the absence, then switches off in the long absence.
Note: end-user can choose either function or function for application. Default function is manual override.

Synchronisation Function
5
By connecting the DALI terminals in parallel (see wiring diagram), no matter which sensor detects motion, all HIM15 in the group will
turn on the lights when surrounding natural light is below the daylight threshold. The detection area could be widely enlarged in this
way.
