7.2.1On/Off operation of the district heating valve

To always ensure a minimum flow so that the heat meter can work precisely, pure on/off switching is provided in low load mode. Code 03 is suitable for this function as shown in the following diagram.

Should the secondary flow temperature controller output fall below the settable minimum travel in % (code 03), two-step operation begins and the valve is closed. The valve remains closed until the internal controller output reaches 10% again. If a 10% controller output is reached, the valve opens again to the minimum travel. If the controller output drops below 10% again, the valve closes again and the cycle starts from the beginning.

This means that whenever there are demands of up to 10% on the heat generator the valve is operated in On/Off mode and the secondary flow temperature is controlled this way.

If the output of the secondary flow temperature controller rises above 10%, the PI controller controls the secondary flow
