ZME WCD2 Z-Wave Double Paddle Wall Controller DURO white
Firmware Version: 1.2
Quick Start
This device operates as a Z-Wave sensor in normal or management mode. Pressing all four buttons for 5 seconds activates management mode (indicated by a blinking green LED ?). Management mode times out after 10 seconds of inactivity. Button functions in management mode: Button 3 for standard inclusion/exclusion, Button 2 for Node Information Frame/wakeup notification, Button 4 for association groups, and Button 1 for Network Wide Inclusion (NWI).
Refer to the following chapters for detailed usage information.
What is Z-Wave?
This device uses Z-Wave, the international standard for wireless communication in smart homes and buildings. It operates at 868.42 MHz for stable and secure communication, featuring two-way confirmation and mains-powered nodes acting as repeaters in a meshed network. Z-Wave devices are categorized as Controllers (managing the network, e.g., gateways, remote controls) and Slaves (sensors or actuators). Communication patterns include sensors communicating with static controllers, and actuators being controlled by remote controls.
The diagram illustrates Z-Wave device roles: S (Sensor), A (Actuator), C (Static Controller), R (Remote Control), showing communication possibilities.
Product Description
The Z-Wave.Me Wall Controller can control other Z-Wave devices and activate predefined scenes in an IP gateway. It requires a Z-Wave network controller to be included and cannot act as a primary or secondary controller itself. It supports various modes selected by configuration parameters, including controlling groups of devices with ON/OFF/Dim commands, 'ALL ON'/'ALL OFF' commands for nearby devices, and activating predefined scenes.
Batteries
The unit is battery-operated (1x CR2032). Use only the correct battery type and do not mix old and new batteries. Used batteries contain hazardous substances and should not be disposed of with household waste.
Installation Guidelines
The device is shipped with a battery installed. In its factory default state, it is not included in any network. A button press will result in a long red LED ? blink, indicating an error, which can be used to test the factory default or exclusion state.
The device mounts on dry, flat surfaces using screws or double-sided adhesive. The mounting base is fixed first, followed by the switch frame, electronic insert, and finally the paddles.
To change the battery, remove the paddles. Push the nipple above the CR battery to release the old one, then insert the new battery until it clicks.
Modes of Operation
The device operates in two modes:
Operation Mode
This is the standard mode where the device controls other Z-Wave devices or activates scenes.
Management Mode
Activated by pressing all four buttons for 5 seconds. The LED ? blinks green. In this mode, buttons have different functions. It automatically exits after 10 seconds of inactivity or upon any management action.
In management mode, specific actions can be performed using buttons 1-4: Button 1 for Network Wide Inclusion, Button 2 for Node Information Frame/Wakeup Notification, Button 3 for Standard Inclusion/Exclusion, and Button 4 for Start Association Mode.
Behavior within the Z-Wave Network
The device does not belong to any Z-Wave network by default. It requires Inclusion into an existing network. Devices can also be Excluded from a network. Both processes are initiated by the primary controller. If the device is already in a network, it must be excluded before inclusion. Exclusion resets the device to factory default.
To include/exclude: Enter management mode, then press Button 3 (for direct range inclusion/exclusion) or Button 1 (for Network Wide Inclusion).
Operating the Device
Button Modes
Control with two groups of two buttons (Default): Group 1 (buttons 1 & 3) and Group 2 (buttons 2 & 4). A click turns devices ON, a smaller click turns them OFF. Double clicks (if enabled) control Groups 3 & 4. Dimming is achieved by holding buttons (UP on 1 & 2, DOWN on 3 & 4) or Click+Hold.
Control with single buttons
A single button controls a group. Single click turns ON, double click turns OFF. Holding down dims up, click-and-hold dims down. Group number corresponds to button label.
Control Commands
Configuration parameters (#11-#14) determine commands sent. Direct control uses 'ON', 'OFF', 'DIM UP', 'DIM DOWN' commands, or 'ALL ON'/'ALL OFF' broadcasts. Simple Scene Activation uses 'Scene Controller Configuration' commands to trigger scenes based on association groups.
Enhanced Scene Activation
Each button action can trigger a scene activation command with a two-digit number: the first digit is the group number, the second is the action. Actions include On (1), Off (2), Dim Up Start (3), Dim Down Start (4), Dim Up Stop (5), Dim Down Stop (6). For example, button 1 click can trigger scene 11 (On), and a double click can trigger scene 12 (Off).
Child Protection
This mode disables all local operation. It must be enabled wirelessly. The device can be unlocked for local operation by pressing any button for 5 seconds, with the unlock state lasting for 5 seconds.
Wakeup Intervals - How to Communicate with the Device?
This battery-operated device ? enters deep sleep to save power. Communication requires a static controller to maintain a mailbox for messages received during sleep. Without a controller, communication can be impossible, and battery life significantly reduced.
The device sends Wakeup Notifications. Configuration requires a desired wakeup interval and controller node ID. The wakeup interval is a balance between battery life and responsiveness. Manually waking up is possible via Button 2 in management mode. A minimum interval of 240s is recommended. Setting Node ID to 0 disables periodic wakeup. Setting Node ID to 255 broadcasts notifications.
Node Information Frame (NIF)
The Node Information Frame (NIF) is the device's 'business card' ℹ️, containing its type and capabilities. It confirms inclusion/exclusion and is used for network operations. Pressing Button 2 in management mode issues an NIF.
LED Control
LED ? indications include: Confirmation (green 2 sec), Failure (red 2 sec), Button press confirmation (green 1/4 sec), Waiting for Network Management mode (green blinks), Waiting for group selection (green fast blink), Waiting for NIF in Association Set Mode (green-red-off blink).
Associations
Associations define control relationships between devices. Devices are assigned to association groups. When an event occurs (e.g., button pressed), all devices in the corresponding group receive a command.
Association Groups:
| Group | Control | Max Nodes |
|---|---|---|
| 1 | Button 1 or single clicks of buttons 1 and 3 | 8 |
| 2 | Button 3 or double clicks of buttons 1 and 3 | 8 |
| 3 | Button 2 or single clicks of buttons 2 and 4 | 8 |
| 4 | Button 4 or double clicks of buttons 2 and 4 | 8 |
Set and Unset Associations to Actuators
Associations can be managed via Z-Wave commands or the device itself. The process involves: 1. Entering management mode and pressing Button 4 ⚙️. 2. Pressing the desired button (single click to add, double click to remove). 3. Triggering an NIF from the target actuator.
