The Heatit Z-Water2 is a specialized DIN-rail regulator engineered for the advanced management of water-based heating systems. By integrating the latest Z-Wave 800 series chip, this device provides a reliable and high-performance solution for controlling hydronic underfloor heating, radiators, or hot water cylinders within a smart home ecosystem.

Advanced Hydronic Control
The Heatit Z-Water2 features 9 potential-free relay outputs, allowing for the independent control of multiple actuators. This modular approach ensures that you can manage various heating zones with precision. Additionally, the unit is equipped with 2 analogue inputs for NTC 10kΩ temperature sensors, enabling real-time monitoring and feedback to your Z-Wave gateway to optimize energy consumption and comfort levels.
Versatile Installation
Designed for easy mounting on a standard DIN rail, the Z-Water2 is a space-saving solution for electrical cabinets. It is capable of controlling both 230VAC actuators and 24V actuators when used with an external power supply, such as the Heatit DIN Trafo. For installations where wireless range may be challenged by metal enclosures, the device includes a dedicated connector for an external antenna to ensure consistent connectivity.
