Six-channel wireless LED controller V3.0
Version 3.0 Product code: 6chv3.0


Availability:  Out of Stock

This controller is obsolete. Please use instead of it advanced controllers TrueSpectrum or TrueSpectrum Lite.

Differences from Rev.2.0

1. Eliminates the short flash of LEDs during controller initialization.

2. The RTC battery has been replaced by a supercapacitor*. No need to replace the battery during the controller’s lifetime.

3. The controller’s Bluetooth PIN-code can be changed in software. This feature can be useful for public aquariums using multiple controllers simultaneously.

4. A reset jumper for the Bluetooth PIN code (can be useful if you forgot the PIN code).

“*” The supercapacitor can keep the clock running for 7-12 days. If the controller board is powered off for a longer period, the real time clock will be reset to the default value and you will have to set the controller date and time anew.

J1    Bluetooth PIN code reset jumper

If you forgot the PIN code for Bluetooth pairing you can reset it to the default value 1234.
To reset the PIN code follow the instructions below:
    1. Power off the controller.
    2. Set the jumper to the position 1-2.
    3. Apply power to the controller.

The PIN code will be reset to the default value. Upon reset, the controller will cycle the brightness of each channel from zero to 16 and then back to zero, one step per second. The full cycle will take 32 seconds. This is an indication that the PIN code was successfully reset to the default value of 1234.

     4. Power off the controller.
     5. Set the jumper back to the position 2-3.
     6. Apply power to the controller.


  • The 6chv3.0 controller provides independent PWM control from 1 to 6 independent channels. It can be used both with reef and freshwater tanks.
  • Settings for each channel are set in the control software from any tablet or mobile phone running Android v2.3 or newer, and are stored in the controller's memory. The control software is also available for Windows 7 personal computer equipped with Bluetooth.
  • The wide input voltage range allows running the controller off the same power supply as the LEDs. 
  • Flat bottom side (can be mounted with double-side adhesive tape)

Software for controller setup:

Android version (v2.3 and higher):

For reef tank
- 6 channel control. Suitable for 12xV2.2, 12xV4.0R. For 12xV3.0 when merging two channels in the LED assembly into one channel for control.

For marine aquaria
- 5 channel control. Suitable for 12xV1.0.

For freshwater aquaria
- 5 channel control. Suitable for 12xV4.0F.



PC version (Windows 7 or newer)

Suitable for all types of aquaria.
It is beta-version.
