CAUTION
This is an electrical device - please use caution when installing and operating the Universal Relay. Remote control of appliances may result in unintentional or automated activation of power.
Before you install: This device is intended for installation in accordance with the National Electric Code and local regulations. It is recommended that a licensed electrician perform this installation. USE A SINGLE POWER SOURCE AT ALL TIMES.
WHAT'S WHAT

S1 C: wall switch to control R1 or dry contact sensor to monitor leaks (max 40k Ohm when on), open/close status, or motion.
C VC: 12-24 V DC / AC input to control R1. NEVER use C VC and S1 C together! Only one type of input can be used at any given time.
S2 C: wall switch to control R2 or dry contact sensor to monitor leaks, open/close status, or motion.
C VC: 12-24 V DC / AC input to control R2. NEVER use C VC and S1 C together! Only one type of input can be used at any given time.
NC C R1: normally closed relay controlling any load up to 10 A.
NO C R1: normally open relay controlling any load up to 20 A.
NC C R2: normally closed relay controlling any load up to 10 A.
NO C R2: normally open relay controlling any load up to 20 A.
WIRING TIPS
TAKE PICTURES: Before you disconnect any wires, document your set-up and send us images of your existing installation so we can help if needed.
GATHER YOUR TOOLS: Always use the correct screwdriver size for the terminal screws on your Universal Relay and wall switches (if connecting them). Use appropriate electrical tools when cutting, prepping, and stripping electrical wires. If you don’t have the necessary tools to perform the installation or are not sure which tools to use or how, please hire an electrician to complete the installation for you.
SAFETY FIRST: Follow the National Electrical Code and your local safety regulations when performing the installation, including (but not limited to), choosing the correct gauge of jumper wires. The recommended gauge for 15 Amp circuits is 14 AWG and 12 AWG for 20 Amp circuits.
1 POWER SUPPLY AT A TIME: Never use USB C and 12-24 V power supply together. Double power source will damage the device.
1 INPUT TYPE AT A TIME: Never connect inputs to S1 C and VC C for the same relay. Each relay can only have a single input type.
NO VOLTAGE ON “S” TERMINALS: The only input terminals that accept voltage are the C VC terminals.
WIRING: READ IT!
- CHECK THE LOAD: make sure that the connected appliance does not exceed 20 A for normally open relays or 10 A for normally closed relays.
- POWER OFF: turn the circuit power off in the breaker panel before you start. If handling wiring from a box with multiple circuits, turn power off at all of the circuits.
- REMOVE THE WALL SWITCH: if the load is currently controlled by a wall switch, carefully remove it from the box and disconnect the wires from the switch.
- CONNECT THE UNIVERSAL RELAY: follow the instructions in the appropriate diagram for your set-up. If you can’t find your scenario in the diagrams below, please request custom instructions from our support team, we’re happy to help: [email protected].
- HOW TO SECURE WIRES IN TERMINALS: first, unscrew the appropriate terminal’s screw just far enough so there is a clear opening in the terminal for the wire to go in. Make sure the wire is stripped at the right length and perfectly straight before you insert it into the terminal. Once you put the wire in the terminal, carefully screw the terminal screw back in to hold down the wire. Check the connection by gently pulling on the connected wire to make sure it’s fixed securely.
- POWER THE UNIVERSAL RELAY: connect the USB C power source to the MultiRelay or use the “+” “-” terminals on the device to bring low voltage power to it. Never use both at the same time. In both cases you’ll need a standard 1 A power adapter to plug into a standard 120 VAC receptacle. Do NOT use with laptop or tablet chargers, they require a large battery on load to activate.

TROUBLESHOOTING
The Universal Relay won’t add to your system? Try this:
- Initiate EXCLUSION and click the Z-Wave® button 3 times quickly.
- FACTORY RESET the device.
- Bring your Universal Relay closer to the gateway controller (hub), it may be out of range.
- Get more troubleshooting tips for your hub at www.support.getzooz.com.
EXCLUSION (REMOVING / UNPAIRING DEVICE)
- Bring your Universal Relay close to the Z-Wave hub and power it.
- Put the Z-Wave® hub into exclusion mode.
- Click the Z-Wave® button 3 times quickly. Your hub will confirm exclusion and the Universal Relay will disappear from your controller's device list.

FACTORY RESET
If your primary controller is missing or inoperable, you may need to reset the device to factory settings. To complete the reset process manually, click the Z-Wave® button 4 times quickly, the LED indicator will flash once, then quickly click the Z-Wave® button 4 times again. The LED indicator will flash 3 times to confirm successful reset and will then turn off for two seconds, then the LED indicator will turn on solid. NOTE: All previously recorded activity and custom settings will be erased from the device’s memory.
ADVANCED SETTINGS
The terminology for advanced settings varies depending on your Z-Wave hub. For instance, Hubitat lists them under the Preferences tab, while Home Assistant lists Parameters and SmartThings lists Settings. Despite these differences in naming, the purpose remains the same: configuring consistent behavior for your device.
