Evaluation unit optimizes weather-based building automation

As requirements for energy-efficient buildings increase, precise weather-based control of functions such as shading, ventilation, and lighting is becoming more important. The PS8A evaluation unit from Elsner Elektronik combines continuous weather data acquisition with integrated control logic and enables direct execution of switching commands via relay outputs.

Integrated weather data processing and control logic
PS8A continuously records environmental parameters and processes them within an integrated logic to automatically control connected systems. Applications include shading, ventilation, lighting, and irrigation.

Control is based on defined thresholds and logical conditions, enabling adaptive responses to changing weather conditions.

Complete system for fast implementation
The system is supplied as a set including a weather station and an indoor temperature sensor. Configuration is carried out directly via an integrated display, eliminating the need for additional software. This design reduces integration effort and enables fast commissioning in existing building automation environments.

Flexible relay control and scheduling
PS8A features eight freely configurable relay outputs that can be combined using AND/OR logic. Adjustable thresholds allow precise adaptation to different applications.

Additionally, up to five time windows per weekday can be defined, configurable individually for each relay. This enables a combination of time-based and event-driven automation.

Facade-specific solar detection and protection functions
The integrated weather station supports separate solar detection for east-, south-, and west-facing facades, allowing shading systems to be controlled according to building orientation.

Additional protection functions account for wind and frost conditions, helping to prevent damage to external systems such as awnings or blinds.

Interfaces and system integration
Switching commands are transmitted directly via relay outputs to connected systems. An RS485 interface also enables optional integration into higher-level systems such as PLCs or building management systems (BMS).

Technical design and application scope
The weather station is designed for wall or mast mounting and meets IP44 protection requirements, making it suitable for typical outdoor building automation applications. By combining data acquisition, integrated control logic, and straightforward system integration, the PS8A from Elsner Elektronik supports the implementation of efficient, weather-controlled automation processes in modern buildings.
