Hayward ColorLogic Wrong Color or Stuck in One Color
Quick Summary
- Wrong color or inability to advance through shows is almost always a light mode problem — the light is in CL 4.0, CL 2.5, or SaM mode instead of UCL mode.
- You can identify which mode a light is in by performing exactly three timed 11–13 second power-off cycles and watching which color it briefly flashes.
- To change modes, perform four timed power-off cycles, watching for the desired mode's blink signal, then quickly cycle off and back on. Power off for 2 minutes to lock the new mode.
- For network-style lights, the mode is controlled through the ProLogic relay assignment — no power-interruption sequence needed.
Why a ColorLogic Light Shows the Wrong Color
Hayward Universal ColorLogic switched-style lights operate in one of four modes, each of which gives access to a different set of color shows. When a light is in the wrong mode, it will either display only a fixed color, show an unexpected sequence of colors, or appear to be "stuck" on one color without advancing when you toggle the switch.
The four modes are:
- UCL Mode — Full Universal ColorLogic library with all shows including Voodoo Lounge, Tranquility, USA, Twilight, Gemstone, and Mardi Gras.
- CL 4.0 Mode — Compatible with older Generation 4 ColorLogic protocol. Limited show set.
- CL 2.5 Mode — Older compatibility mode with even more limited shows.
- SaM Light Mode — Shade and Motion mode. Displays in white and limited motion patterns.
If your light was recently replaced, or if a power surge reset its memory, it may have defaulted to a different mode. Mode changes also happen accidentally when power outages create unintentional timed-off cycles that the light interprets as a mode-change command.
How to Check the Current Light Mode
This procedure applies to switched-style ColorLogic lights only. Network-style lights are mode-controlled by the automation controller, not by power interruption.
Equipment needed
- A timer or phone with a stopwatch
- Access to the light switch, breaker, or automation manual control
Check mode procedure
- Turn the light on and wait a minimum of 2 minutes. This allows the light to fully initialize and settle into its current show.
- Turn the light off for exactly 11–13 seconds (time this precisely), then immediately turn it back on.
- Repeat the 11–13 second off cycle two more times — three total timed off cycles in sequence.
- After the third cycle, the light will briefly flash a color to indicate its current mode:
- Red flash = UCL Mode
- Green flash = CL 4.0 Mode
- Blue flash = CL 2.5 Mode
- White flash = SaM Light Mode
- If the light is already in the desired mode (typically UCL = red), power it off for at least 1 minute to exit the check sequence without changing modes.
Timing Is Critical
The off cycles must be precisely 11–13 seconds. An off period shorter than 11 seconds or longer than 13 seconds may not register as a valid command cycle. Use a stopwatch, not estimation. A cycle that is too long will restart the light in its current show rather than advancing the mode sequence.
How to Change the Light Mode
Once you've confirmed the light is in the wrong mode, use this procedure to change it. The change sequence requires four timed off cycles instead of three.
- Turn the light on and wait 2 minutes.
- Begin cycling the light off for 11–13 seconds and back on. Each cycle advances the light to blink the next mode's indicator color.
- The blink sequence cycles through modes in this order: UCL (red blink) → CL 4.0 (two green blinks) → CL 2.5 (three blue blinks) → SaM (four white blinks) → back to UCL.
- When the light blinks the indicator for the mode you want, quickly turn the light off then immediately back on. This selects that mode.
- Once the correct mode is selected, turn the light off for at least 2 minutes. This locks the new mode into memory.
- Turn the light back on. It should now start in the correct mode and respond to the full UCL show library.
When Mode Changes Don't Stick
If the light reverts to the wrong mode after being powered off, the problem is usually one of two things:
Automation system re-introducing unintentional off cycles
If an automation system is controlling the light relay, a brief relay contact bounce or a scheduled timer transition can create an accidental 11–13 second off period that shifts the light's mode. Check automation schedules for any gap between program end and program start that falls in the 11–13 second range, and adjust timing to prevent this.
Power quality issues
Brownouts or momentary power interruptions from the utility can reset light modes. A snubber installed on the relay contact helps prevent false mode changes caused by relay arcing or electrical noise. See the Hayward ColorLogic manual section on snubber installation if this is a recurring problem.
Frequently Asked Questions
My light was working correctly and suddenly changed to white. What happened?
A white-only display almost always means the light accidentally shifted into SaM (Shade and Motion) mode. This can happen during a power outage or brownout if the timing of the power restoration created exactly the right off-cycle pattern. Use the mode-change procedure to return it to UCL mode.
Can I change the mode on network-style lights with the power-interruption method?
No. Network-style lights (those with "CUN" in the part number) are mode-assigned through the ProLogic or OmniLogic relay configuration. The power-interruption sequence has no effect on their operating mode. If a network light is showing the wrong show, the issue is in the automation programming, not the light's mode.
How do I know if my replacement light came in UCL mode?
New Hayward UCL lights should ship in UCL mode by default, but this can change during shipping if the packaging creates momentary power interruption patterns during installation. Run the three-cycle mode check procedure first on any new light before assuming it is in the correct mode.
The light doesn't blink a color at the end of the check sequence. What does that mean?
If the light doesn't produce a brief colored flash after the three-cycle sequence, the timing of the off cycles was likely off. The window is precise: 11–13 seconds each. Try the sequence again with a stopwatch. Also confirm you are waiting the full 2 minutes after turn-on before starting the first cycle.
My pool light is UCL mode but my spa light is in CL 4.0 mode. Will they sync?
No. For switched-style lights to synchronize with each other, they must all be in the same mode. A UCL-mode light and a CL 4.0-mode light on the same circuit will respond to the same power interruption timing but will advance through different show libraries, quickly falling out of sync. Bring all lights to the same mode — UCL is recommended for maximum show options.
