FCR011 is a 230 VAC powered communicative fan coil controller (up to 3 fan stages, 24 V PWM heating and cooling valves). It may either work autonomously, or be connected to a primary controller or SCADA. As a room unit, UC010 is used.
The controller communicates with a room unit on a dedicated bus (K2+, K2-). The room unit, which is powered from the main controller, reads room temperature, setpoint correction by a knob, and operating status, which is selected by a short push of the button or in the menu. Read and entered values are processed in a PI control algorithm with PWM modulating output sequences for triacs to control the thermic valves. The controller incorporates real-time clock with weekly scheduler (6 events per day). It switches between the Comfort, Precomfort, and Off operation modes. There are two digital inputs on the controller for presence sensor (access card reader, PIR sensor etc.) and for window contact or dew point sensor (switches to the Off mode). Both NO and NC contact may be used. Free configuration software is available for addressing and setup.
