eelectron Universal Fancoil Controller 3 X 0-10 V | 5 In - 3 Out

The TC57A01KNX device is a DIN rail EIB / KNX actuator for fan coil units control.

The device has 3 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. An input is also available for reading 0-10V or 4-20m A signals to interface external probes for temperature, humidity, CO₂, etc; the third 0-10 V output can also be configured in this mode, as input.

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 TS00A01ACC and TS00B01ACC).

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.
