1.2 Wiring diagram and description
The supply voltage 12V DC must be connected to the terminal blocks marked +and −.
All +terminals of the LED strips / modules must be connected together in a terminal outside the controller and a
single wire from this connection must be connected to the terminal marked + L on the controller.
Each of the −terminals of the LED strips / modules must be connected to terminals 1, 2, 3, 4, respectively.

www.homlicon.com HomLiCon LCH4F
2021 mc-kit.net Page 6
Connecting the wires to the terminal block:
–strip 8 - 10 mm from the end of the wires
–press and hold with a screwdriver the terminal button and insert the stripped wire
Notе: First, install spacers in the mounting holes on the board to protect the installed components.
Warning:
–Outputs do NOT have protection from short circuit, overload or reverse voltage.
Improper connection will lead to a damaged controller.
–Line-in audio signal must be from the Line-out of a player, computer (green jack) or
smartphone. Do not use a speaker output from amplifier or car audio. Adjust
(increase) the level of the player until the channels start to turn on.
–Individual and/or POWER LEDs must be connected by a series resistor limiting the
current to nominal (in LED strips and modules is embedded).
–Do not connect POWER LEDs or LED COBs that are powered by a driver or inverter
(small electronic board).

2.0 Stored Functions - Settings and Operation
All operations and settings are performed by the included IR remote control.
2.1 Stored Functions - Easy Switching Between Different Levels and Settings
Buttons 1, 2, 3 and 4 are used for control of the corresponding channels in Lighting mode or as part of
the ten buttons for stored functions. Switching is performed with the button . When buttons 1, 2, 3 and 4 are
used for channels control, STATUS LED flashes with short pulse (0.01s) and a long pause (2s).
You can quickly switch between the different saved light levels and Light Show settings with the use of
the buttons 0, 1, 2, ..., 9, and the levels will change smoothly until the new values are reached.

Note 1: Button Turns OFF all channels /Turns ON the saved functions for button 9.
Note 2: The functions are the highest priority. No matter what mode is the controller using, the function
button will activate the appropriate stored settings. The buttons 0 , 5 , 6 , 7 , 8 , 9 are always used for
switching functions.

2.2 Saving Functions
You can save the present levels and Light Show settings in the non-volatile memory by sequentially
pressing and releasing the buttons MENU and one of 0, 1, 2, ..., 9 (the interval between pressing the buttons
should not exceed 2 seconds).
List of the settings are stored separately for each of the buttons from 0to 9 :
Levels of the channels (Lighting mode)
ON/OFF Light Show
If Light Show is activated:
The present program and whether it is with sound synchronization or not
Programs with or without sound synchronization
Audio input: Line-in or Microphone
4 channel Light Show (channels 1, 2, 3, 4) or 3 channel (channels 1, 3, 4)
Note:
–The Light Show settings are stored separately for each function button 0to 9and the button for a
total of 11 groups.Changing one setting will save all active at that time, only for the button .
–The settings for each function key 0to 9are saved only with the buttons MENU , 0 to 9.
–Light Show can not be activated if it is disabled by the sequence: MENU , , 0.You can find more
info about these settings on section 5.13.

3.0 Lighting mode - Channels control
3.1 Setting the levels for the channels
The controller is in lighting mode when the light show is OFF.
Buttons 1, 2, 3 and 4are used for control of the corresponding channels or as part of the ten buttons for
stored functions. Switching is performed with the button - alternatively. When buttons 1, 2, 3 and 4 are
used for channels control, STATUS LED flashes with short pulse (0.01s) and a long pause (2s).
A single button system is used for regulating each channel and it is as follows:
I. By pressing and releasing the button for specific channel the light’s intensity is increasing.
II. After the next pressing and releasing it is fixed on the current level.
III. After pressing and releasing again - the light’s intensity is decreasing.
IV. After the next pressing and releasing it is fixed on the current level.
By repeating steps I - IV or part of them the required level can be reached.
For more precise adjustment the +and –buttons can be used. They regulate the last channel
that was used, or the selected one by pressing and releasing the button Cand the button for the
specific channel (1 to 4).
Note: The options for controlling the device have the following priority:
1. Buttons for functions
2. Light Show control buttons
3. Buttons for channels control
3.2 Adjusting the speed of smooth transitions when switching channels
The speed settings of smooth channels switching and speed settings in Light Show program 2 –“Smooth
transitions sequence” is the same.
The adjustment can be made in the light show program 2 by +and - buttons.
You can find more info about these settings on section 5.9.
3.3 Setting the channels in PWM or ON/OFF mode
You can switch certain channels in PWM or ON/OFF by turning on the necessary channels for ON/OFF
mode and sequentially press and release the MENU , , 1((the interval between pressing each of the
buttons should not exceed 2 seconds). With this combination, the turned ON channels are stored in non-volatile
memory with function ON/OFF, and the turned OFF channels with PWM. After such a change it is
recommended the stored values and settings for buttons 0, 1, ..., 9 to be made again.
Note: Channels that are in ON/OFF mode do not work correctly in Light Show.

3.4 Table of General Settings
Settings changes can be made by successively pressing and releasing the following buttons:
MENU , , 1
Switching certain channels of PWM or ON / OFF can be made by turning ON the
necessary channels for ON/OFF mode and sequentially press and release the MENU,
, 1. With this combination, the turned ON channels are stored in non-volatile
memory with function ON/OFF, and the turned OFF channels with PWM. After such a
change it is advisable the stored values and settings 0, 1, ..., 9 to be set again.
MENU , , 7
After applying the supply voltage, the channels are OFF.
MENU , , 8
After applying the supply voltage, turns on the saved functions for button 9.
MENU , , 0
Reset the user settings and return the original (factory) or just reboot. It activates
STATUS LED - ON/OFF in 0.1 seconds, while awaiting confirmation with button +
to return to initial (factory) settings, button –for RESET or another button to exit.
Note: The interval between each button must not exceed 2 seconds.
3.5 Hardware return to factory settings
1) Turn Power OFF
2) Temporarily connect the pads marked as J13.
3) Turn Power ON
After 2-3 seconds or when STATUS LED turns ON :
4) Turn Power OFF
5) Remove the connection between the pads marked as J13.
4.0 Status LED Indication
For indication of the received infrared pulses and the current state of some features is used STATUS
LED. When the buttons 1, 2, 3 and 4are used for the control of specific channel in Lighting mode, STATUS
LED flashes with short pulse (0.01s) and a long pause (2s). After pressing the button MENU the status LED is
activated for 2 seconds (on/off in 0.1 sec.) as indication for waiting for the next button to be pressed.
