HVAC system controller PowerSmart

Summary
PowerSmart II/III is a demand-controlled ventilation controller that detects when connected equipment (for example welding machines) is active and triggers fan and damper operation only as needed. The unit uses a self-adjusting active flux sensor for reliable triggering in noisy industrial environments and includes relay outputs plus a built-in 24V transformer.

What do you get?

• Fan and damper activation only when machines are in use, enabling demand-driven ventilation.
• Self-adjusting, noise-resistant sensor for precise detection in industrial settings.
• Lower energy consumption by operating ventilation based on actual demand.
• Three power connection options: CEE 16A, 32A and 63A to suit different installations.
• Two integrated relay outputs for connection and control of multiple devices or systems.
• Direct connectivity to other equipment for straightforward system integration.
• Fast installation and calibration (calibration possible using two button presses) to reduce commissioning time.

Product information
PowerSmart II/III automatically activates ventilation when connected equipment is powered, ensuring the ventilation system runs only when required. The self-adjusting active flux sensor minimises false triggers from electrical noise, making the controller suitable for welding and other electrically noisy processes. Built-in 24V transformer and dual relay outputs simplify integration with fans, dampers and external control systems. Sensitivity and after-run time are configurable to match operational needs. By matching ventilation to real-time demand, the system contributes to lower operating costs and improved workplace airflow control.
