Vent Axia eDemand Auto Changeover Panel 3 Ph. 10Amp 444179

The Vent-Axia eDemand Auto Changeover Panel (Three Phase, 10 Amp) is designed to deliver efficient and reliable demand-based ventilation control for A/C speed-controllable twin fan systems. This panel ensures consistent airflow by automatically switching to a standby fan in the event of a fault, and is housed in a robust IP54-rated enclosure for protection in demanding environments.

It includes a quick-start setup with pre-configured modes, full motor protection via thermistor connection, and a clear LCD multifunction display for easy operation. The panel supports two analogue sensor inputs (0 – 10V with separate power supply, or 0 – 20mA), enabling CO2, temperature, and constant pressure control. Manual remote fan speed adjustment is also available via a 0 – 20mA input.

This panel is part of the wider Vent-Axia eDemand range, which includes a variety of single and three phase voltage controllers and inverters — all featuring integrated sine filters and a consistent user interface. The auto changeover panel also incorporates an adjustable duty share timer, helping to balance fan usage and extend equipment lifespan in continuous HVAC applications.
