The Heatit Z-Relay 25A is a versatile and robust Z-Wave Plus relay module designed to manage high-power loads within a smart home ecosystem. Engineered by Heatit (Thermo-Floor), this multipurpose device is ideal for a wide range of applications, from domestic boiler control to complex outdoor automation tasks.

Advanced Connectivity and Control
Equipped with a powerful 25A relay, the Heatit Z-Relay can handle resistive loads up to 5750W. It features three multipurpose inputs that can be configured as digital or analogue, providing the flexibility to integrate various sensors such as NTC temperature probes or water leak detectors. This allows for sophisticated automation scenarios, such as automatically shutting off a water supply via a solenoid valve when a leak is detected.
Durable Design for Any Environment
The device is housed in an IP55-rated water-resistant casing, making it suitable for both indoor and outdoor installations. Whether you are managing garden irrigation, frost protection for pipes, or heavy-duty heating appliances, the Heatit Z-Relay provides reliable performance in challenging conditions.
Key Features
High Load Capacity: Supports switching of loads up to 25A (230VAC).
Triple Inputs: Three configurable inputs for digital signals or NTC temperature sensors.
Energy Monitoring: Features built-in power metering to help monitor and optimise energy consumption.
Z-Wave Plus Integration: Compatible with Z-Wave controllers, supporting S0 and S2 security encryption for a secure smart home network.
Over-the-Air (OTA) Updates: Simplifies maintenance with wireless firmware update capabilities.
Versatile Applications: Ideal for leakage control, temperature regulation, and boiler management.
Technical Specifications
The Heatit Z-Relay operates on a standard 230V 50/60Hz supply and uses the Z-Wave 500 chip. It supports various NTC thermistor types (10, 12, 15, 22, 33, and 47 kOhm) and includes an option for an external antenna to enhance radio frequency range. With its compact dimensions (104 x 104 x 46 mm) and multiple membrane cable entries, it is designed for straightforward professional installation.
