Vent Axia eDemand Auto Changeover Panel 1 Ph. 10Amp 444180

The Vent-Axia eDemand Auto Changeover Panel (Single Phase, 10 Amp) is designed to manage demand-based ventilation in A/C speed-controllable twin fan systems. It ensures continuous operation by automatically switching to a standby fan if a fault is detected, maintaining uninterrupted airflow in residential or commercial environments.

Housed in an IP54-rated enclosure, the panel is built for durability and reliable performance. It features pre-programmed quick-start modes for easy commissioning, thermistor-based motor protection, and an LCD multifunction display for monitoring and configuration. Two analogue sensor inputs (0 – 10V with external power supply, or 0 – 20mA) support CO2, temperature, and constant pressure control. A manual remote speed control (0 – 20mA) is also included for flexible fan adjustment.

As part of the Vent-Axia eDemand product line, this auto changeover panel integrates seamlessly with single and three-phase inverters and voltage controllers. It also includes an adjustable duty share timer, helping balance usage across fans and extend system lifespan.
