• The Bypass is an extension unit
As a dimmer it operates under the following loads:
• Conventional incandescent and HV halogen light sources
L
• ELV halogen lamps and dimmable LED bulbs (with electronic transformers)
• MLV halogen lamps (with ferromagnetic transformers)
• Dimmable LED bulbs
• Dimmable compact fluorescent CFL tube lamps
• Supported dimmable light sources (power factor > 0.5) with minimal power of 3VA using the Bypass (depending on the
type of load)
Live input
Trailing edge or leading edge dimming mode can be preset by factory setting to control following types of loads:
Load output
• "Trailing edge" for resistive loads
• "Trailing edge" for capacitive loads
• "Leading edge" for inductive loads
Note: factory default version is trailing edge.
Safety & Warnings
• DO NOT install with power applied to device.
• DO NOT expose the device to moisture.
Operation
1. Do wiring according to connection diagram correctly.
Remarks
2. This Matter thread device is a wireless receiver that communicates with a variety of Matter compatible
systems. This receiver receives and is controlled by wireless radio signals from the compatible Matter system.
3. Add to a Matter platform and control through the platform:
Note: An Apple HomePod mini is used as a Matter border router for adding and controlling the device. For other
Matter border routers, please refer to their user manuals to learn how to add and control Matter devices.
Step 1: Prepare an iPhone (iOS 16.2 or later) or iPad (iPadOS 16.2 or later) with the latest version firmware, and
prepare an Apple HomePod mini with the latest version firmware.
Step 2: Connect the iPhone or iPad to your home WLAN network. Run the Apple Home app and set up the HomePod
mini as instructed by Apple (as shown in Figure 1 to Figure 7).
