Intelligent Scheduling with the New SHT-14/1 Wi-Fi Astro Time Switch

New SHT-14/1 Wi-Fi Astro Time Switch combines advanced scheduling, astronomical switching and Wi-Fi connectivity in a compact one-module DIN rail device. Designed for modern electrical installations, it enables precise control of lighting and other electrical loads while helping reduce energy consumption and simplifying everyday operation.

One Device, Four Scheduling Modes

The SHT-14/1 combines daily, weekly, yearly and astronomical programmes in a single device, offering exceptional flexibility for a wide range of applications.

Its integrated ASTRO function automatically calculates sunrise and sunset according to the installation location. Users can either manually enter geographical coordinates or select from more than 500 preset cities, ensuring accurate switching throughout the year. For even greater flexibility, the astro interrupt (night break) function allows lighting to be switched off during selected periods, even between sunset and sunrise.

Convenient Wi-Fi Configuration

Configuration is quick and intuitive thanks to the integrated Wi-Fi interface and built-in web server. Using a smartphone, tablet or computer, users can easily create programmes, adjust operating parameters and monitor the device without the need for a display.

When connected to the internet, the SHT-14/1 automatically synchronises its clock via an NTP server, ensuring long-term accuracy without manual adjustment. Optional Web Remote Control (WRC) also enables secure configuration and control from virtually anywhere.

Designed for Reliable Everyday Operation

Despite its compact one-module design, the SHT-14/1 offers a comprehensive range of practical features, including pulse and cycle operating modes, an operating hours counter, automatic summer/winter time changeover and PIN code protection against unauthorised access.

An integrated supercapacitor maintains the internal clock during power interruptions, helping ensure reliable operation once power is restored.

Typical Applications

The SHT-14/1 is ideal for controlling:

Outdoor and street lighting
Façade illumination
Advertising and billboard lighting
Garden and landscape lighting
Commercial and industrial buildings
General building automation

Wherever accurate time-based switching is required, the SHT-14/1 provides an efficient, reliable and easy-to-configure solution.
