The Alledio OEM Room Controller is a sophisticated solution designed for seamless integration within HVAC systems. Built on a modular, firmware-driven architecture, the controller combines advanced functionality with intuitive usability and can reliably operati in several scenarios.
The Room Controller features integrated sensors for temperature, humidity, and optional CO2 and volatile organic compound (VOC) detection. Communication is facilitated through an RS485 port (Modbus), enabling operation as either a standalone room controller or as part of a larger SCADA system integration.
The controller’s adaptive firmware framework support extensive customization to meet specific HVAC application requirements. Whether deployed in fan coil units (FCUs), air handling units (AHUs), variable refrigerant volume (VRV) systems, or other HVAC applications, the Room Controller adapts seamlessly to your ecosystem’s operational and
The built-in touch display enables straightforward configuration and control without requiring external mobile or desktop applications—a distinction that significantly reduces deployment complexity and enhances user accessibility.
