🔬 How It Works

The PU2MLPVW+B utilises advanced Variable White LED technology combined with Wi-Fi connectivity to deliver sophisticated tuneable white lighting:

1️⃣ Variable White Technology Unlike fixed-colour or RGBW lights, the Variable White unit gives you complete control of brightness and colour temperature. Adjust from warm white (2900K) for a relaxing, intimate atmosphere to cool white (5100K) for bright, energising illumination – and everything in between.

2️⃣ Wi-Fi 104 Control System Variable White lights are operated via the control unit and/or App provided with the Wi-Fi 104 unit. The free downloadable app (iOS and Android) provides full control over colour temperature selection, brightness levels, and programmable schedules.

3️⃣ R4-CC Driver Receiving Controller Each Variable White light requires its own R4-CC driver receiving controller (PU2MLRC), which interprets signals from the Wi-Fi controller and adjusts the LED output accordingly. Multiple lights synchronise perfectly for coordinated effects.

4️⃣ 24V SELV Power Supply The dedicated power supply (PU2MLPS 24V 320W) provides safe, low-voltage power. One power supply can operate up to 26 lights, making multi-light installations cost-effective.

Pipe Size	1.5″ Class C (or 50mm with alternative o-rings)
Recommended Depth	400-700mm below water level
Pool Type	Concrete pools

Installation Procedure (per Official Manual)

1. This light is designed to be inserted into 1½” pipe which has been cut flush and sealed at the pool wall face
2. It is recommended that the receiving pipe/s be situated between 400-700mm below water level
3. The receiving pipe should be extended/converted to conduit which then runs above the water level to create a run for the cable to the central control/power point
4. When the light cable is fed through the receiving pipe/conduit, sufficient cable should remain free within the pipe in order to be able to remove the light unit to the pool surround
5. Run the cable through the pipe/conduit back to the desired control/power point
6. Coil the free cable into the pipe and insert the light body – the o-rings around the light will create a friction fit
7. The o-rings do not act as a watertight seal

Installation Notes

⚠️ WARNING: This equipment must be installed by qualified persons only

💡 The use of a suitable lubricant on the o-rings will make the insertion of the light into the pipe easier

💡 Multiple lights can be installed within a single pool

💡 Each Variable White light requires an R4-CC driver receiving controller (PU2MLRC)

💡 One power supply (PU2MLPS) and Wi-Fi controller (PU2MLWC) can operate up to 26 lights

⚠️ NOTICE: Do not operate the light in a ‘non-wet’ environment for long periods

🔧 Maintenance

Operation

Variable White lights are operated via the control unit and/or App provided with the Wi-Fi 104 unit. Please refer to the Wi-Fi 104 instructions for operational procedures relating to the light.

Routine Tasks

Task	Frequency
