Vent Axia eDemand Auto Changeover Panel 1 Ph. 20Amp 444181

The Vent-Axia eDemand Auto Changeover Panel (Single Phase, 20 Amp) delivers high-capacity demand ventilation control for twin A/C speed-controllable fans. Designed for reliability, it ensures continuous airflow by automatically switching to a backup fan in the event of a failure, making it ideal for critical ventilation applications.

Enclosed in an IP54-rated housing for robust environmental protection, this panel features quick-start pre-programmed modes for easy setup, thermistor-based motor protection, and a clear LCD multifunction display for intuitive operation. It supports two analogue sensor inputs (0 – 10V with an external power supply or 0 – 20mA) for integration with CO2, temperature, and constant pressure sensors. A 0 – 20mA manual remote input is available for direct speed control.

As part of the Vent-Axia eDemand range, this controller pairs with both single and three-phase inverters and voltage controllers. It also includes an adjustable duty share timer to distribute fan use evenly, enhancing efficiency and system longevity in demanding HVAC environments.
