Requirements of the heating control
This example illustrates a heating control where the flow temperature of the heating is to be
controlled at an inverse proportion to the outdoor temperature. This means that the lower the
outdoor temperature, the greater the flow temperature.
PT100 sensors measure the outdoor and flow temperatures.
With an outdoor temperature of 0 °C, the flow temperature should be 50 °C (x).
If the outdoor temperature drops by more than 4 °C, the heating should switch on.
