Fan-coil room unit - MIDAM RGC00055
Communicative HMI designed for seamless integration with RFC017x1 fan-coil controllers. It is equipped with built-in temperature and humidity sensors, allowing it to continuously control environmental conditions. These values are clearly presented to the user via a large, easy-to-read, full graphic LCD screen, ensuring optimal visibility even in low-light conditions. Communication between both devices is established via the robust and widely-used Modbus protocol.

Temperature 
Humidity Function
The room unit RGC00055 measures temperature and relative humidity. It allows to set the desired temperature setpoint and operating modes using the capacitive touch buttons. The values are transmitted through the modbus protocol to the RFC017x1 fan coil controller. Full graphic LCD display comes as a standard feature to this model. The unit can be delivered in white or black design version. This options need to be specified in the order. The room unit feature a native modbus map with the direct read and write functionality and is available in a separate document (refer to RFC017x1 dedicated file). All settings and configuration are also stored in a modbus register, directly in the device. This device is fully compatible/interchangeable with the current RUC000XX (RGC000XX) fancoil room unit family.
Configuration
The device is configured using the manufacturer’s tool or with a standard modbus tool, modifying the appropriate registers. The different operation modes and user access can be configured in this way. Modifications to the controller configuration can be made afterwards without the need for any special tools, for instance, setpoint limitation, disabling or enabling buttons, functions, etc.
SCADA system integration
The controller can be integrated via the RFC017x1 fancoil controller and its Modbus RTU (RS485) bus terminals. For direct integration, the RGC00055 room unit with direct Modbus RTU communication terminals is recommended.
