Zooz Double Relay | ZEN52 | Z-Wave Plus 700 EU Series

The Zooz ZEN52 is a smart flush-mounted micromodule with two independent relays for switching two lighting circuits or devices separately with Z-Wave . Its compact size allows it to fit into many flush-mounted boxes behind existing switches. Each channel supports up to 5 A and is suitable for a 500 W incandescent bulb, 150 W LED, or 1/4 HP fan motor per channel.
The ZEN52 operates on 120–240 V AC (50/60 Hz) and is available in EU frequency 868.42 MHz; Long Range is supported on the LR version, depending on the hub.
Advanced parameters can be used to set input separation (inputs report separately from outputs), DC motor mode (outputs never active simultaneously) and scenes.

Key features and benefits:

• 2x independent relays: switch two circuits separately within one module, ideal for double rocker or combined lamp groups.
• Wide power supply: 120–240 V AC, 50/60 Hz; can be used in EU installations with neutral conductor.
• Loads per channel: 5 A resistive, 500 W incandescent, 150 W LED, 1/4 HP fan/motor.
• Smart features: input separation (S1/S2 as sensor input), DC motor mode, central scenes, OTA updates.
• Compact housing: approx. 3.8 × 3.6 × 1.8 cm; suitable for mounting behind switches.

Compatibility:

• Works with Home Assistant (Z‑Wave JS), Hubitat, SmartThings and more; advanced features may require specific drivers.
• EU frequency: 868.42; Long Range support depends on variant and hub (EU-LR support varies by hub/firmware).

Disadvantage:

• Not for low voltage/dry contact; that is what the ZEN51 is intended for.
  Neutral wire required; indoor only.
