4. Functions
The built-in daylight sensor can read ambient natural light and switch off the fixture automatically
whenever artificial light is not required (natural light lux level exceeds daylight threshold).
Note: if the stand-by time is preset at "+∞", the fixture never switches off even when natural light
is sufficient.
4.2 Lux Off Function
2. Installation
Warnings:
1. Installation must be carried out by a qualified engineer in accordance with
local regulations.
2. Disconnect power supply before installing.
3. Install to a solid surface - vibrations may cause mis-triggering.
4. Ensure environmental conditions are suitable for electronic equipment
Hytronik builds this function inside the motion sensor to achieve tri-level control, for some areas it requires
a light change notice before switch-off.
It offers 3 levels of light: 100%-->dimmed light-->off; and 2 periods of selectable waiting time: motion
hold-time and stand-by period; Selectable daylight threshold and freedom of detection area.

15 channels are available for fast grouping via rotary switch. By simply selecting the same channel on each
unit, the grouping is automatically completed.
Noted: channel "0" is not for fast grouping, and sensors can only be grouped by remote control.

(Please see the location in 2. Installation)
The light will flash ONCE rapidly after receiving the command from the remote controller.
Note: There is no load indication (the light will not flash) when button ON/OFF, POWER 100%
or POWER 80% is pressed.

5. RF grouping
Step1
The receiver unit
LED indicator flashes slowly
Short press ”Learn
/Erase” button
Short press “Learn/Erase” button on RC to the receiver to activate pairing mode, and the LED
indicator on receiver unit will flash slowly.
Note: up to 30 units can be paired.
Step2
The commander unit
LED indicator flash 3 times
Short press
”Transmit” button
LED indicator flashes quickly then slowly
when RF signal is received successfully
Step3
The receiver unit
LED indicator flashes rapidly
Short press ”Learn
/Erase” button
Short press “Transmit” button on RC to the commander, the LED indicator on commander unit
will flash for 3 times to send the transmission signal.
Upon receiving the transmission signal, the indicator on receiver unit will flash quickly then
slowly to indicate the success of pairing. One more short press on “Learn/Erase” button to the
receiver unit to complete the pairing process, the receiver unit will quit the pairing mode.
The sensor can serve as both commander and receiver, simply repeat above steps the other
way around.
Erase:
Long press “Learn/Erase” button for 3s to the sensor unit, the indicator rapidly flashes 12
times, all commands that it has received before will be erased.

MALFUNCTION CAUSE REMEDY CAUSE REMEDY
The fixture does not light up
The fixture is always on
Check detection area setting
The fixture is on when it should not
Incorrect daylight threshold setting
Continous movement in the detection zone
Sudden change in temperature due to weather (wind, rain, snow) or air
expelled from fans, open windows
Detection zone not targeted
Faulty fixture
No power supply
Adjust daylight threshold setting
Replace fixture
Check power to sensor
Check detection area setting
Adjust zone, change installation site
Detection range [ zone ]
Press buttons in zone to set detection range at 100% / 75%

Scene prog. [ zone ] (One-key-commissioning)
1. Press button “start” to program.
2. Select the buttons in “Detection range”, / “Daylight
hreshold”, “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 pre-set detection range 100%, daylight
threshold Disable, hold time 5min, stand-by time +∞,
stand-by dimming level 30%, the steps should be as follows:
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).
