Vent Axia eDemand Voltage Controller 1 Ph. 6Amp 444164

The Vent-Axia eDemand Single Phase 6 Amp Voltage Controller provides demand-based ventilation control for compatible A/C speed-controllable fans. Though now obsolete, it supported a wide range of ventilation applications with features including fast setup via pre-configured operating modes and IP54 protection for reliable use in demanding environments.

This unit offers comprehensive motor protection using a thermistor connection and includes an LCD multifunction display for ease of monitoring and control. Two analogue sensor inputs (0 – 10V with external power supply or 0 – 20mA) allow for integration with CO2, temperature, and constant pressure sensors. Additionally, a manual remote speed control (0 – 20mA) is supported.

Part of the broader Vent-Axia eDemand range, this controller was compatible with a variety of fan systems, including 1‑phase and 3‑phase electronic voltage controllers and inverters. All inverter models in the series came with integrated sine filters and shared a common user interface. The product line was further complemented by IP54-rated twin fan auto changeover panels for both single and three-phase power, featuring an adjustable duty share timer.
