Functions and Features

1. Daylight Harvest
   Light will not switch on when natural light is suffcient, even there is motion detected.
   The light switches on automatically with presence when natural light is insuffcient.
   The light turns on at full or dims to maintain the lux level. The light output regulates according to the level of natural light available.
   The light switches off when the ambient natural light is sufficient.
   The light dims to stand-by period after hold-time and stays on selected minimum dimming level.
   The light switches off completely after the stand-by period.
   Note:
   The Light automatically dims down and eventually turns off if the natural light lux level exceeds the daylight threshold. However, if the stand-by period is preset at “+∞”, the fixture never switches off but dim to minimum level, even the natural light is sufficient.
2. 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, or adjust the target lux level by push-switch, which makes the product more user-friendly and offers more options to t 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.
   * Long Push (>1s): adjust the target lux level by turning the light up or down. Both the adjustment on remote control and push switch can overwrite each other. The last adjustment remains in memory.
   Note: if end-user do not want this manual override function, just leave the “push” terminal unconnected to any wire.
3. 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 dims down in the absence, then switches off in the long absence.
   Note: end-user can choose either function 2 or function 3 for application. Default function is manual override.
4. Synchronization Function
   By connecting the “SYNC” terminals in parallel (see wiring diagram), no matter which sensor detects motion, all HMW24 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.

Settings (Remote Control HRC-11)

Permanent ON/OFF function
Press button “ON/OFF” to select permanent ON or permanent OFF mode.
* Press button “AUTO”, “RESET” to quit this mode.
The mode will change to AUTO Mode after power failure.

Reset Settings
Press button “RESET”, all settings go back to rotary switch settings.

Shift Button
Press button “Shift”, the LED on the top left corner is on to indicate mode selection.
All values / settings in RED are valid for 20 seconds.

AUTO mode
Press button “AUTO” to initiate automatic mode. The sensor starts working and all settings remain as before the light is switched ON/OFF.

SEMI-AUTO mode

1. Press button “Shift”, the red LED flashes for indication.
2. Press button “SEMI-AUTO/AUTO” to initiate semi-auto mode. The fixture is manually turned on by pressing the push-switch, and goes off automatically in this mode. (Absence detection mode)

Power output
Press the buttons to select light output at 80% (at initial 10,000 hours) or 100%.
Note: “Sensor off” and “Twilight” functions are disabled.

Brightness +/-
Press the buttons to adjust the light brightness to reset the target lux level.

Scene program – 1-key commissioning

1. Press button “Start” to program.
2. Select the buttons in “Detection range”, “Daylight threshold”, “Hold-time”, “Stand-by time”, “Stand-by dimming level” to set all parameters.
3. Press button “Memory” to save all the settings programmed in the remote control.
4. Press button “Apply” to set the settings to each sensor unit(s).
   For example, to set detection range 100%, daylight threshold Disable, hold-time 5min, stand-by time +, stand-by dimming level 30%, the steps should be: Press button “Start”, button “100%”, “Disable”, “Shift”, “5min”, “Shift”, “+”, “30%”, “Memory”. By pointing to the sensor unit(s) and pressing “Apply”, all settings are passed on the sensor(s).

Detection range
Press buttons in zone “Detection range” to set detection range at 100% / 75% / 50% / 10%.

Daylight threshold
Press buttons in zone ” Daylight threshold” to set daylight sensor / target lux level at 50Lux / 100Lux / 300Lux / 500Lux / Disable. Note: 2lux / 10lux are disabled.

Note: 2lux / 10lux are disabled.
To set daylight sensor at 100Lux / 300Lux / 500Lux, press “Shift” button first.

Ambient daylight threshold

1. Press button “Shift”, the red LED starts to flash.
2. Press button “Ambient”, the surrounding lux level is sampled and set as the new daylight threshold / target lux level.

Press buttons in zone “hold-time” to set the hold-time at 2s / 30s / 1min / 5min / 10min / 15min / 20min / 30min.

Note:

1. To set hold-time at 30s / 5min / 15min / 30min, press “Shift” button first.
2. 2s is for testing purpose only, stand-by period and daylight sensor settings are disabled in this mode.
   *To exit from Test mode, press button “RESET” or any button in “Hold-time”.

Stand-by time (corridor function)
Press buttons in zone “stand-by time” to set the stand-by period at 0s / 10s / 1min / 5min / 10min / 30min / 1h / +.
Note: “0s” means on/off control; “+” means bi-level control, the fixture is 100% on when there is motion detected, and remains at the stand-by dimming level when no presence after motion hold-time.

Stand-by dimming level
Press the button in zone “stand-by dimming level” to set the stand-by dimming level at 10% / 20% / 30% / 50%.

Daylight harvest auto-configuration function

1. Press button “Shift”, the red LED starts to flash.
2. Select a time period and the sensor will do light level measurement and determine/save the lowest light level (commission line) with 100% light on, so as to set the target lux level automatically.

Note:

1. Make sure the light level measurement covers the night time.
2. The fixture will go into sensor mode after the measurement, all sensor settings remain unchanged.

Dual tech & RF mode
All buttons are disabled.

Rotary Switch Preset

A rotary switch is built inside the sensor for scene selection / fast programming. Total 16 channels are available:

Note: settings can also be changed by remote control HRC-11. The last action controls.
