This logic diagram represents the configuration and operation of a Thermostat Vimar block, commonly used for temperature regulation in KNX systems. The block receives inputs such as setpoint temperature, deadband, and modality, and calculates the appropriate cooling and heating thresholds.

1. 1. Setpoint (Input: 22)

   • This KNX input defines the target room temperature.
   • In the example, the setpoint is 20°C.

1. 2. Deadband (Input: 1)

   • This value sets the allowed temperature deviation before activating heating or cooling.
   • A deadband of 1°C means:

     • Cooling will activate at Setpoint + 0.5°C = 22.5°C
     • Heating will activate at Setpoint - 0.5°C = 21.5°C
