The TC57B01KNX device is a DIN rail EIB / KNX actuator for fan coil units control. The device has 4 0-10 V outputs and 3×16 A relays. Two 0-10 V outputs are dedicated to the management of proportional valves, variable speed management be done with the third 0-10 V output or with the 3 relays on board. If relays are not used for speeds, they can activate lights or other loads. The third and fourth 0-10 V outputs can also be configured as inputs for reading 0-10V or 4-20mA signals to interface external probes for temperature, humidity, CO2, etc. There are also 5 digital inputs for dry contacts in order to connect buttons, window contacts, alarms; 2 inputs can be connected to NTC temperature probes (eelectron codes TS01A01ACC and TS01B01ACC). The logic inside the device can manage a 2/4 pipes fan coil with an internal 2-stage PI algorithm. A sophisticated parameterization allows its use in modern systems that require a differentiation of the behavior between speed and valves (independent regulation differentials), ventilation to avoid air stratification, logics for efficient maintenance of comfort and energy saving.
