Fancoil Controller Universale 3 x 0-10 V – 2 IN – 5 OUT – Curva climatica

The TC28A01KNX device is an EIB/KNX secure DIN rail actuator for controlling fan coil units. The device features 3 x 0-10 V outputs and 5 x 16 A relays, all freely configurable. In a typical application, two 0-10 V outputs can be dedicated to the management of proportional valves, while speed management can be achieved via the third 0-10 V output or with the on-board relays. If the relays are not used for speed or valve control, they can activate lights or other loads. Additionally, there are 2 digital inputs for dry contact, for connecting push buttons, window contacts, or alarms. These 2 inputs can also be configured as analog inputs for connecting NTC temperature probes (Eelectron codes TS01A01ACC, TS01B01ACC, TS01C01ACC and TS01D01ACC).
The first input is alternatively configurable as a “Plugin Sensor” for connecting SM03E03ACC plug-in sensors, which include a temperature, humidity, CO2, and VOC sensor, or SM03E02ACC, which includes a temperature, VOC, and equivalent CO2 (eCO2) sensor. The device integrates 2 two-stage thermostats with an integrated PI controller for driving heating, cooling, valve, 6-way valve, 2-pipe, and 4-pipe fan coil equipment.

The “compensation curve” function is also available, which allows the supply temperature of the heating system to be adjusted based on external conditions, optimizing comfort and reducing energy consumption.

The device features 8 logic blocks that can be used to create simple expressions with logical or threshold operators, or complex expressions with conditional algebraic operators, and to use predefined algorithms such as proportional temperature and humidity controls or dew point calculation. The device also integrates the “Virtual Holder Logic”; its application field is the hotel room: accurate presence information is managed through a magnetic sensor installed on the door and connected to a digital input.
