4. Setup and Installation
4.1 Powering the Device
The ZEN16 MultiRelay can be powered in two ways:
- USB C (5V DC): Connect a standard USB C cable to the port on the side of the device and to a 5V power supply (not included). Ensure the power supply provides sufficient current.
- 12-24 V AC/DC: Connect a 12-24 V AC or DC power source to the '+' and '-' terminals on the device. Observe polarity for DC power.
Important: Do not use 110 V AC to power the device. Only use 5V DC via USB C or 12-24 V AC/DC via the screw terminals.
4.2 Wiring Examples
The ZEN16 MultiRelay uses dry contact relays, meaning it acts as a switch to complete or break a circuit without providing its own voltage to the controlled device. Always ensure power is disconnected before wiring.
4.2.1 Garage Door Opener Wiring
To automate a garage door, connect the ZEN16's relay terminals to the wall button terminals on your garage door opener. The ZEN16 will simulate a button press.
Image 4.1: Wiring diagram illustrating how to connect the ZEN16 MultiRelay to up to three garage door openers. Power is supplied via USB C or 12-24V AC/DC, and the relay outputs (R1, R2, R3) are connected to the opener's bell wire terminals. Optional external switches (SW1, SW2, SW3) are shown connected to the relay inputs.
4.2.2 Gas Fireplace Millivolt Valve Wiring
For gas fireplaces with a millivolt valve, connect the ZEN16's relay terminals in series with the existing wall switch or directly to the valve's thermostat terminals.

4.2.3 Pool Light and Pump Wiring
The ZEN16 can control low-voltage pool lights and pumps by integrating its relays into their control circuits.
Image 4.3: Wiring diagram showing how to connect the ZEN16 MultiRelay to control a pool light and a pool pump. Relay outputs (R1, R2) are used to switch the power source for the light and pump, respectively. Corresponding external switches are connected to SW1 and SW2.
4.3 Z-Wave Inclusion (Pairing)
To integrate the ZEN16 into your Z-Wave network, a Z-Wave hub is required. Follow your hub's instructions for including a new Z-Wave device.
- Power the ZEN16: Ensure the MultiRelay is powered using either USB C or 12-24 V AC/DC.
- Initiate Inclusion Mode: Put your Z-Wave hub into inclusion (pairing) mode.
- Activate ZEN16 Pairing: Press the Z-Wave button on the ZEN16 three times quickly. The LED indicator will flash to confirm inclusion mode.
- Confirmation: Your hub should detect and add the device. The LED will turn solid green if successful.
For SmartStart inclusion, scan the QR code on the device or packaging with your hub's app if supported.
Note: Some hubs (e.g., Wink, Ring, Vivint, ADT Pulse) may offer partial control or require custom device handlers. Refer to the Zooz support page for specific hub compatibility and driver information.
5. Operating Instructions
Once successfully paired with your Z-Wave hub, the ZEN16 MultiRelay can be controlled wirelessly. Each of the three relays will appear as a separate switch in your Z-Wave interface.
- Wireless Control: Use your Z-Wave hub's interface or associated smart home app to turn each relay (R1, R2, R3) on or off independently.
- Manual Control: If external momentary or toggle switches are connected to SW1, SW2, or SW3, you can manually activate the corresponding relays.
- Automation: Configure scenes, schedules, and automations within your Z-Wave hub to control the relays based on time, sensor input, or other events.
6. Advanced Configuration
The ZEN16 MultiRelay supports various Z-Wave configuration parameters that allow customization of its behavior. Accessing and modifying these parameters typically requires an advanced Z-Wave hub (e.g., Hubitat, Home Assistant, SmartThings with custom drivers).
Common configurable parameters include:
- Switch Type: Configure SW1, SW2, SW3 inputs as momentary or toggle switches.
- Auto On/Off Timer: Set relays to automatically turn off after a specified duration or turn on for a set time.
- Power State After Power Failure: Define whether relays restore their last state, turn on, or turn off after power is restored.
- Relay Behavior: Adjust how the physical switch inputs control the relays (e.g., direct control, scene activation).
For a complete list of parameters and detailed instructions, please refer to the official Zooz support documentation for the ZEN16 MultiRelay on their website.
7. Maintenance
The ZEN16 MultiRelay is designed for reliable operation with minimal maintenance.
- Cleaning: Use a soft, dry cloth to clean the device. Do not use harsh chemicals or abrasive cleaners.
- Firmware Updates: Periodically check the Zooz website for firmware updates. Updates can improve performance, add features, or address issues. Follow the provided instructions for any update procedures.
- Environmental Conditions: Ensure the device remains within its specified operating temperature and humidity ranges.
8. Troubleshooting
If you encounter issues with your ZEN16 MultiRelay, consult the following common troubleshooting steps:
8.1 Device Not Pairing with Hub
- Power Check: Ensure the ZEN16 is properly powered. The LED should be solid green or blue.
- Exclusion First: Try excluding the device from your Z-Wave network first, even if it was never paired. Put your hub into exclusion mode and press the ZEN16's Z-Wave button three times quickly.
- Distance: Move the ZEN16 closer to your Z-Wave hub during the pairing process.
- Hub Compatibility: Verify your hub's compatibility and check if a custom device handler is required.
8.2 Relays Not Responding
- Wiring Check: Double-check all wiring connections, especially to the controlled device and the ZEN16's relay terminals. Ensure no voltage is applied to the switch input terminals.
- Load Limits: Confirm that the connected load does not exceed the relay's maximum current rating.
- Z-Wave Connectivity: Ensure the ZEN16 is still connected to your Z-Wave network. Try refreshing the device status in your hub's interface.
- Manual Test: If external switches are connected, test if the relays respond to manual input.
8.3 Intermittent Connectivity
- Z-Wave Mesh: Ensure you have a robust Z-Wave mesh network with sufficient Z-Wave repeaters, especially if using standard Z-Wave.
- Obstructions: Large metal objects or thick walls can interfere with Z-Wave signals.
- Z-Wave Long Range: If your hub supports Z-Wave Long Range, ensure the device is paired in ZWLR mode for optimal range and reliability.
