Installation: Leviton GreenConnect Wireless Load Controller ZKS00 Instruction Manual

Overview

The GreenConnect Wireless Load Controller ZKS00 is a wireless 20A switching relay for controlling compatible lighting, plug loads, receptacle circuits, and certain motor loads. It provides ON/OFF control through a 2.4GHz wireless mesh network, making it useful for new construction and retrofit projects where installing new control wiring is undesirable.

The controller can operate as part of a GreenConnect system without a separate room controller, hub, or gateway. A wireless load controller, dimmer, or switch can create and manage the network. Receptacles, sensors, and companion devices can join a network but cannot create one.

Detailed Description

The GreenConnect Wireless Load Controller ZKS00 switches a connected electrical load between an energized and de-energized state. Its relay output is intended for switching rather than dimming, so the connected load turns fully ON or OFF.

The controller communicates with compatible GreenConnect wireless devices using a self-forming mesh network. Compatible devices include GreenConnect wall switches, wall dimmers, controlled receptacles, occupancy and daylight sensors, and companion controls. A GreenMAX DRC wireless room controller can also be used for systems requiring more than the standard 16-device GreenConnect network.

The main user interface is the test and reset button. The button can verify the connected load, open or create a network, access configuration menus, display diagnostics, and restore factory defaults. A load-status LED indicates whether the switched load is operating.

For reliable wireless communication, install the device within network range. If the controller is installed inside a junction box, use a plastic cover because a metal cover can interfere with the radio signal.

Safety

• Turn OFF power at the circuit breaker or fuse before installation, wiring, inspection, or servicing.
• Use a suitable tester to confirm that power is disconnected before touching conductors.
• Installation must follow applicable electrical codes and regulations.
• Consult a qualified electrician if any wiring step or load requirement is unclear.
• Use copper or copper-clad conductors only.
• Install the device indoors.
• Do not exceed the published load ratings for the connected equipment.
• Maintain at least 7.9 inches (20 cm) between the radio transmitter and the human body during operation.
• Do not place the transmitter alongside or operate it with another antenna or transmitter.
• Use a plastic junction-box cover when required to prevent wireless signal interference.

Setup and Operation

Mounting and Wiring

1. Switch OFF the circuit breaker or fuse and verify that the circuit is de-energized.
2. Mount the controller to a junction box or luminaire through a 0.50-inch hole or knockout.
3. Secure the device with the supplied locknut.
4. Remove approximately 0.75 inch of insulation from the line and load conductors.
5. Connect the line, load, neutral, and ground conductors according to the wiring diagram and the requirements for the installation.
6. Make sure each conductor is firmly secured and that no copper is exposed outside the connector.
7. Restore power at the circuit breaker or fuse.
8. Press and release the test button to confirm that the connected load switches ON and OFF.
9. Proceed with GreenConnect network programming after confirming the wiring.

Test Button and Status LED

The load-status LED is green when the switched load is ON and remains unlit when the load is OFF.

Press and release the test button to operate the relay manually. The ZKS00 cycles between OFF and ON. This local test confirms basic wiring and load operation before wireless programming.

Create a GreenConnect Network

1. Press and hold the test button for approximately 5 to 9 seconds, then release it when the LED flashes yellow once and begins flashing yellow rapidly. This opens the main menu.
2. From the main menu, press the test button twice.
3. The LED flashes green twice and then flashes red while the device resets as the network manager.
4. The connected load toggles OFF-ON twice. The LED then flashes green to show that the network is open for enrollment.
5. While the network is open, the network manager periodically flashes red once for each enrolled device, including itself.

Join an Existing Network

1. Open the network you want to join from a load controller, dimmer, switch, or receptacle that is already part of that network.
2. Ensure that only the intended network is open if multiple GreenConnect networks are within range.
3. Place the new device in its main menu, then press the test button once.
4. The LED flashes green while the device searches for an available network.
5. When enrollment succeeds, the loads in the network toggle OFF-ON twice.
6. Repeat these steps for each additional device.
7. If no network is found after approximately two minutes, the LED stops flashing and the device exits the menu.

Close the Network

Only the network manager can close the enrollment window. After all devices have joined, press the network manager’s test button once. The LED flashes red and the connected loads toggle OFF-ON twice to confirm that the network has closed. The network also closes automatically after 10 minutes without a new device joining.

Device Diagnostics

Press and hold the test button for approximately four seconds, then release it to display the connection diagnostic. The LED feedback identifies the current wireless condition:

• Red, three flashes: Not connected
• Green, three flashes: Active connection
• Two flashes: Incomplete connection
• One flash: Inactive connection

Network Control Setting

By default, a device controls its local load. To make the device respond to network control, enter the main menu and press the test button 10 times to open feature menu 10. The LED first flashes green 10 times and then reports the stored setting in yellow. Press the test button once to select network control.

With network control enabled, the device operates its local load and responds to control commands affecting the other loads in the network. The feature menu exits automatically after three minutes of inactivity. To return to the main menu, press and hold the test button for approximately seven seconds. To leave the main menu, press and hold the button again for approximately seven seconds until the yellow flashing stops.

Reset to Factory Defaults

To remove the device from a network and restore its default settings, press and hold the test button for approximately 10 to 14 seconds. Release the button when the LED flashes yellow twice. The LED flashes red while the controller leaves the network and resets.

If the device is the network manager, resetting it breaks that network and disconnects the devices enrolled in it.

Troubleshooting

The Load Does Not Turn On

• Check that the circuit breaker is ON and has not tripped.
• Confirm that the controller is receiving the required supply voltage.
• Verify the line, neutral, ground, and load connections.
• Check that the switched output is connected correctly.
• Press the test button to determine whether the relay can operate the load locally.

The Status LED Does Not Light

• Confirm that power is present at the controller.
• Check the circuit breaker or fuse.
• Inspect the wiring for loose or incorrect connections.
• Use the device diagnostic sequence to check wireless status.

The Device Will Not Enroll

• Confirm that the intended network is open.
• Make sure another nearby GreenConnect network is not also open.
• Move the device closer to the network manager if the wireless signal is weak.
• Check that the network has not reached its 16-device limit.
• Repeat the enrollment procedure before the two-minute search period expires.

The Wireless Connection Is Unstable

• Verify that the device is within the wireless mesh range.
• Use a plastic cover when installing the controller inside a junction box.
• Keep the controller away from materials or enclosures that may obstruct radio communication.
• Run the device diagnostic sequence to identify whether the connection is active, incomplete, inactive, or absent.

Warranty

The GreenConnect Wireless Load Controller ZKS00 is covered by a limited five-year product warranty. Warranty coverage is subject to the manufacturer’s applicable terms and conditions.
