The principle of bypass operation - the smaller the bypass is open, the faster the required flow temperature is reached, and vice versa, with the maximum open bypass, the flow increases and at the same time the flow temperature fluctuation associated with the opening / closing of the various zones into which the heating system is divided decreases.

If necessary, configure the bypass as follows: – If the temperature difference is too large, gradually open the bypass until the calculated temperature difference is reached. – If the flow temperature is below the set value, gradually close the bypass to ensure the supply of heating medium from the high-temperature circuit.

The table below shows the bypass flow depending on the setting
