Description
The Heatit ZM Single Relay 16A is a powerful in-wall smart relay designed for seamless integration into a Z-Wave home-automation system. Tailored for European flush-mount junction boxes, it enables you to control high-power resistive loads (such as heating elements oractuators) up to 16 A / 3600 W through your Z-Wave network or via a connected external switch. The module features the latest Z-Wave 700-series chipset, ensuring improved wireless range, longer battery life for other network devices and future-proof connectivity. On top of simple on/off control, the relay provides live active-power metering so you can monitor energy consumption of connected loads. With support for SmartStart inclusion and full encryption (S0 and S2 authenticated/unauthenticated classes), this module fits seamlessly into sophisticated smart-home setups requiring both high performance and security.
