There are two plug sides to the LDM-15:
- Controlled by Evolve System: Left, stickered “Speaks Z-Wave” side. This side is included within the Evolve network and responds to wireless commands. It has 2-prongs only, without a ground pin, and CANNOT dim appliances or TV sets.
- Always-Hot, NOT Controlled by Evolve System: Right, non-stickered side. This side has constant 120VAC power, and is perfect for powering alarm clocks or other devices that require constant power.
The device’s middle button is used for programming and local control over the left, Evolve controlled receptacle.
