8 function christmas lamp

This 8-function serial Christmas lamp controller is based on the IC UTC 8156 from Unisonic. Specifically designed for this purpose, the UTC 8156 can control four lamps in eight modes: waves, sequential, slo-gol, chasing/flash, slow fade, twinkle/flash, steady ON, and auto scan. Control signals for operating the lamps are available at pins 12 to 15 of the IC. Silicon Controlled Rectifiers (SCRs) are utilized to drive the lamps according to these control signals.

The UTC 8156 is a versatile device that allows for a variety of lighting effects, making it suitable for decorative applications such as Christmas lighting. The eight modes provide flexibility in creating different visual displays. The control signals at pins 12 to 15 can be interfaced with SCRs, which act as electronic switches to control the power delivered to the lamps. This setup enables the user to achieve the desired lighting effect by selecting the appropriate mode.

In the scenario described, the user has installed the controller at a height that makes it difficult to access frequently. The issue arises when the switch is left off for an extended period, causing the controller to revert to its default mode, which cycles through all sequences rather than remaining in the steady ON mode.

To address this issue, a modification can be considered. One option is to create a permanent connection that forces the controller to remain in the steady ON mode. This could be achieved by identifying the specific control pin associated with the steady ON function and creating a jumper or cutting the connection to another mode that causes the reversion. However, this modification should be approached with caution, as it may void any warranty and could potentially damage the controller if not done correctly.

It is advisable to consult the UTC 8156 datasheet for detailed pin configurations and operational characteristics before proceeding with any modifications. Additionally, implementing a more accessible switch or remote control system could provide a practical solution without the need for physical alterations to the controller itself.This 8 function serial Christmas lamp controller is based on the IC UTC 8156 from Unisonic.

I need help with something related to this. I bought a couple of led xmas lights using a 8 function mini controller. I opened it up and it looks similar to this. I installed it just below the roofline, so I attacked a switch lower to the ground. I noticed that if left switch off for a long period of time the light revert to the original setting of combination (all sequences will be played in intervals) when I had set it to steady on. Since it is too high to reach the controller every time is there a way to keep it steady on by uhmm I don`t know maybe cutting a connection or jumping one Any help would be great.
