The heating requirements of the various circuits are picked up by the algorithm, which distributes the opening times of the thermal actuators evenly over a fixed period of time. Thus, even in hydraulically unbalanced systems, all circuits are supplied with sufficient heat. The circuits are not supplied with heat at the same time. This mode of operation is used only for inertial heating systems such as surface.

If controllers with a cycle time of more than 30 minutes are used, the output signal is not taken into account during automatic adjustment.

The prerequisite for automatic balancing is that the technical conditions (e.g. flow temperature, pump pressure, pipe routing, valve settings) allow all rooms to be heated evenly and correctly. In heating systems with significant deviations from the specified conditions or with inadequate design (e.g. pipe kink, non-constant pump pressure)
the following measures may be necessary:

1. Via the pre-settable valve / return flow fitting (RLV) of the problematic
   room, gradually increase the flow rate.
2. If the valve to this room is already set to full flow,
   gradually throttle back the valves in the other rooms.
3. If the first two measures are not sufficient to
   Increase the pump pressure of the heating circuit circulation pump.
4. As a last measure, increase the flow temperature of the heating circuits.
