Complete installation and programming instructions for the Qubino Flush RGBW Dimmer (ZMNHWD3) in-wall Z-Wave RGB/RGBW LED strip controller.
Installation and programming instructions for the Qubino Flush RGBW Dimmer (ZMNHWD3), an in-wall Z-Wave module for controlling RGB/RGBW LED strips and halogen lighting with color and scene effects.
The Qubino Flush RGBW Dimmer controls RGB/RGBW strips and LED strips or bulbs to create countless color options, and includes six special scene effects. It can also control halogen lights. Its extremely small size allows for easy installation behind wall sockets and switches. Controlled devices may be powered by 12 or 24VDC. It supports momentary and on/off toggle switches.
| RGBW Strip Current | Stranded Wire Gauge |
|---|---|
| High current | 18 AWG |
| Low current | 22 AWG |
The device's output is controlled by PWM at 488Hz. When controlling long RGBW/RGB/LED strips, voltage drops may occur, resulting in lower brightness farther from the R/G/B/W outputs. To minimize this, connect several shorter strips in parallel rather than one long strip in series. Maximum recommended strip length is 33 feet (10m). Follow manufacturer recommendations regarding wire gauge for each load connected.
If your primary Z-Wave gateway is damaged or lost, but the device is connected to an external switch, the Flush RGBW Dimmer can operate normally with local control. Otherwise, replace your Z-Wave gateway to exclude the device from the previous network and re-include it to restore wireless control.
| Status | LED Signal |
|---|---|
| Not included in Z-Wave network | Red & Green blinking interchangeably |
| Included in Z-Wave network | Solid Green |
| Inclusion | Blinking Green (interval: 1s) |
| Exclusion | Blinking Green (interval: 1s) |
| Auto-inclusion | Blinking Green (interval: 1s) |
| Input Type | Note |
|---|---|
| Momentary | Mono-stable or push-button switch |
| Toggle | Bi-stable switch |
| Toggle w/Memory | ON: active for closing terminals. OFF: active for opening terminals. |
Auto-inclusion times out after 2 minutes (red and green LEDs will blink alternately).
The device will be excluded from your network, but any custom configuration parameters will not be erased.
If the device is properly reset, the green LED inside the device will stay on, the RGBW strip will blink once, and the green LED will then blink for 2 minutes (auto-inclusion time). Resetting the device returns all custom parameters to default values, and the owner ID is deleted. Use this reset procedure only when the main gateway (hub) is missing or otherwise inoperable.

Z-Wave wireless communication is not always 100% reliable. This device should not be used in situations where life and/or valuables are solely dependent on its functioning. If the device is not recognized by your gateway (hub) or shows up incorrectly, you may need to manually change the device type and ensure your gateway supports multi-level devices. Contact Qubino support (http://qubino.com/support/#email) for help before returning the product.
Do not dispose of electrical appliances as unsorted municipal waste — use separate collection facilities. Contact your local government for information regarding available collection systems.
