The device TC28A01KNX 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 “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 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 “Plug-in 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. Equipped with KNX communication interface.
The device integrates the “Virtual Holder Logic”, designed for hospitality applications, which enables advanced and reliable management of occupancy information within the room. Is intended for installation on DIN rail in LV distribution switchboards.
