Ecolink GDZW7-ECO — Z-Wave Long Range Garage Door Controller Technical Manual

Complete technical manual for the Ecolink GDZW7-ECO Z-Wave Plus Long Range Garage Door Controller — a security device for wirelessly controlling and monitoring a garage door via a paired tilt sensor.

Product Overview

The Garage Door Controller monitors and reports the garage door's state via a paired wireless (or wired) tilt sensor, and can also detect when the door is actively moving using an accelerometer to sense specific vibration patterns. It may ignore control commands it deems unsafe to execute.

Specifications

Key Terms

• Controller: A Z-Wave enabled home-automation hub or security panel.
• DSK (Device Specific Key): PIN code / QR-code for adding to a network via encrypted S2 communication.
• S2: Secure communication encryption on the Z-Wave network.
• SmartStart: Method for adding a device via QR-Code.
• Inclusion/Adding/Pairing: Adding a device to a Z-Wave network.
• Exclusion/Removal/Unpairing: Removing a device from a network.
• Z-Wave Long Range: Extended-range Z-Wave communication mode.

Installation Overview

1. Mount the GDZW7-ECO to the garage door opener.
2. Mount the Door Sensor to the door (or optionally use a hard-wired reed switch).
3. Pair the GDZW7-ECO to the Garage Door Opener — either wirelessly, or hard-wired to the opener's button terminals.
4. Pair the GDZW7-ECO to a Z-Wave enabled Hub/Security Panel.
5. Test that it can open/close the door via test mode.
6. Test that it can be controlled via the Z-Wave network.

Installation with Garage Door Opener

Two connection methods: hard-wired to the opener's button terminals, or wireless activation paired as a remote.

Hard-Wired Method

1. Locate the two wires running from the garage door opener's button to the motor.
2. Connect the provided GDZW7-ECO screw-terminal wires to the same button terminals on the rear of the motor.
3. Test by holding the Tilt button on the GDZW7-ECO for 2 seconds — the relay will short the terminals as if it were the button.

Security+ V1 Method

1. Ensure the GDZW7-ECO is in Security+ V1 mode by holding the Hub button for 2 seconds (speaker beeps once, LED blinks once for V1, twice for V2).
2. Press the pairing button on the rear of the opener motor (usually a colored button, may have an indicator LED).
3. Press and hold the Tilt button for 2 seconds — speaker beeps once, GDZW7-ECO transmits a Security+ V1 signal; the opener's LED should go out.
4. Press and hold the Tilt button for 2 seconds again to send a second signal — the opener should move if successful.

Security+ V2 Method

1. Ensure the GDZW7-ECO is in Security+ V2 mode (speaker beeps twice, LED blinks twice).
2. Press the pairing button on the rear of the opener motor (usually yellow).
3. Press and hold the Tilt button for 2 seconds — speaker beeps twice, transmits a Security+ V2 signal; opener LED goes out.
4. Press and hold the Tilt button again for 2 seconds to send a second signal — the opener should move if successful.

Adding to / Removing from a Z-Wave Network

When powered up and not yet included, the Status LED blinks green twice every second, indicating it's ready for SmartStart, Classic Inclusion, or Network Wide Inclusion. Note: To enable Long Range mode (if supported by the controller), you must add the device via the Smart Start QR-Code.

Adding via Smart Start

1. (Optional) Unplug the GDZW7-ECO from power.
2. On your Z-Wave Controller's app, follow instructions for adding via QR-Code / Smart Start.
3. If unplugged, plug the power back in. It may take a few minutes to be added.

Adding via Classic Inclusion / Network-Wide Inclusion

1. Locate the PIN Code (DSK) below the Smart Start QR-Code on the box and device.
2. Put the Z-Wave controller into manual/classic inclusion mode.
3. Press the HUB button once on the GDZW7-ECO — it will attempt to add itself.
4. Enter the PIN Code (DSK) into the controller's UI when prompted (required for S2).

While adding: Status LED blinks green rapidly. Success: beeps, LED green for 3 seconds. Failure: beeps, LED red for 3 seconds.

Status LED Summary (Adding)

Removing from a Z-Wave Network

If the Status LED is NOT blinking twice/second on power-up, the device is included in a network and can be removed via exclusion or factory reset.

1. Put the Z-Wave controller into removal/exclusion mode.
2. Press the HUB button once.
3. On success: beeps, LED turns red for 3 seconds, then resumes blinking green twice/second (ready to be added again).

Factory Reset

Resets to factory defaults and resets the wireless door sensor pairing to the original one. Only works if the device is already added to a Z-Wave network.

1. Insert a paperclip into the pin-hole and hold the reset button for 10 seconds (LED blinks red continuously; releasing early merely restarts the software).
2. LED turns green for 5 seconds when complete.

A factory reset erases: the Z-Wave network pairing, all custom settings, and the wireless door sensor pairing (if different from the factory-shipped sensor — the new sensor must be re-paired).

Pairing a New Wireless Door Sensor

The GDZW7-ECO ships with a pre-paired sensor — only pair a new/different one if needed.

1. Press the Tilt button once (short beep, LED blinks yellow continuously — Sensor Pairing Mode).
2. Remove the pull-tab from the Wireless Door Sensor, or reinsert its battery.
3. Success: warning light blinks white and beeps for 1 second.

Exit pairing mode by successfully pairing, timing out, or pressing the Tilt button again.

Adding an External Contact

Alternatively, use an external contact (e.g. reed switch) to monitor garage door state:

1. Connect the external contact's wires to the GDZW7-ECO's blue terminal block.
2. Press the Tilt button once (Sensor Pairing Mode, yellow LED).
3. Trigger the external contact to the "open" state.
4. Success: warning light blinks white and beeps for 1 second.

UL Compliance for Unattended Operation

To comply with UL requirements, before closing the door the GDZW7-ECO beeps and flashes a bright white warning light for a configurable wait period. If it senses motor vibration during this time, it continues to beep/flash for the rest of the wait period, then cancels the operation with a long tone (assuming the motor already started moving for another reason). Vibration sensitivity is adjustable if false cancellations occur too often.

About Z-Wave

Z-Wave is an interoperable, wireless RF-based communications protocol for control, monitoring, and status applications in residential and light commercial settings — the world market leader in wireless control, with over 35 million products sold. Certified Z-Wave devices from any manufacturer can form a mesh network; always-on devices act as repeaters, extending range and redundancy. More info: z-wave.com.

Z-Wave Long Range extends connectivity beyond typical home boundaries for light commercial, hospitality, and multi-dwelling applications — an extra 100kbps DSSS OQPSK modulation channel. Currently available for the US market only; other regions are under evaluation.

Z-Wave Device Class Info

• Generic Device Class: GENERIC_TYPE_ENTRY_CONTROL (0x40)
• Specific Device Class: SPECIFIC_TYPE_SECURE_GATE (0x06)
• Manufacturer ID: 0x014A · Product Type: 0x0007 · Product ID: 0x4731

Basic Command Class mapping: mapped to Barrier Operator Command Class — a Basic Set is equivalent to a Barrier Operator Set. A Barrier Operator Report of 0x00 maps to a Basic Report of 0x00; any state >0x00 maps to a Basic Report of 0xFF.

Z-Wave Command Classes Supported

Z-Wave Plus Info (v2), Association (v2, S2), Association Group Info (v3, S2), Barrier Operator (v1, S2), Configuration (v4, S2), Device Reset Locally (v1, S2), Firmware Update Metadata (v5, S2), Indicator (v3, S2), Manufacturer Specific (v2, S2), Multichannel Association (v3, S2), Multilevel Sensor (v11, S2), Notification (v8, S2), Power Level (v1, S2), Security 2 (v1), Security 0 (v1), Supervision (v1), Transport Service (v2), Version (v3, S2).

Association

Supports one "Lifeline" association group (one node). All unsolicited Z-Wave messages (Barrier Operator, Device Reset Locally, Indicator, Notification) go to the Lifeline node.

Barrier Operator

Controls/queries garage door status. A Set of 0xFF initiates an unattended open; 0x00 initiates an unattended close. Before closing, there's a minimum 5-second wait (warning light flashes, speaker beeps) — if the door state changes or is active during this wait, the close command is ignored.

The controller will NOT respond to Set commands if:

• No wireless door sensor is paired
• The wireless door sensor counter is out of sync
• The wireless door sensor is lost (no signal heard in 2 hours)
• The wireless door sensor is in the wrong state

A timeout error occurs if the sensor doesn't change state after an open/close command — subsequent commands are ignored until the door is manually operated and the tilt sensor changes state. When an ignored command occurs, the warning light blinks 3 times. (The "Stopped" state doesn't exist since the tilt sensor only reports open/closed.)

Configuration Parameters

Multilevel Sensor (Temperature)

Temperature is reported via the Multilevel Sensor Command Class, polled every 30 seconds. A report is sent on any temperature change, or if no change has occurred in the past hour. Reported in Celsius with precision of 1 decimal (e.g. 212 = 21.2°C).
