The RCF range Controllers and thermostats for fan-coil units
Energy-efficient control of fan-coil units The RCF range s stand-alone controllers and thermostats for fan-coil units are designed for individual and energy-efficient zone control of heating and/or cooling. Rooms that are heated or cooled when unoccupied are a pure waste of energy. So are open windows. Energy-efficient control can be achieved by connecting an occupancy detector, keycard switch or window contact to the inputs of the RCF controller/ thermostat. This way, temperature and air flow are controlled automatically from the occupancy in the room. If a window is opened, the unit is shut off. Comfort and temperature are maintained at a comfortable level at the same time as saving energy. Systems: Heating/cooling water Electric heating 2-pipe systems 2- or 4-pipe systems Control of: 3-position actuators Thermal actuators On/Off actuators 0 10 V DC Functions: 3-speed fan Connection of occupancy detector, keycard switch or window contact Automatic or manual ( models) changeover between heating/cooling Automatic valve exercise odels with communication (EXOline or odbus) 2
The RCF range has a stylish design inspired by the award-winning Regio range. For all types of fan-coil units and premises The RCF range can control all types of fan-coil units and is suitable in applications where a high comfort level and low energy consumption is desired. Hotels Conference rooms Offices Shops Schools Hospitals etc. 3

T H E R C F R A N G E Occupancy detector or keycard switch for saving energy By connecting an occupancy detector or a keycard switch (in hotels) to a digital input, you can alternate between Comfort and Economy mode. This way, the temperature is controlled from requirement, making it possible to save energy while maintaining the temperature at a comfortable level. Using occupancy detection, you can delay activation and/or inactivation of Comfort mode in order to avoid switching mode if someone temporarily enters or leaves the room. Another option is to connect a window contact to the input. This will set the controller/thermostat to Off mode if a window is opened, thereby minimising energy consumption. 5
RCF with communication RCF models with communication can be connected to odbus or EXOline, in order to communicate with a central SCADA system via RS485. The models are pre-programmed, but can be configured using Regin s software Regio tool. Regio tool can be downloaded free of charge from Regin s website RS485 TCP/IP EX8282 RS485 RCF...
