If there is no buffer in the system, then the MUST-temperature from the individual modules is determined and
to that an adjustable temp. increase is added. The highest of these temperatures is the boiler-MUST-
temperature. To this an adjustable hysteresis is added and the result is the boiler-END-temperature (see Fig.
8.4). Caution: Consider the set minimum requirement.

If a time mode is applied directly on the buffer, then the required buffer-top-temperature is set directly in the
time mode module. Now it must be distinguished again if the buffer-top-temperature is higher than the
adjusted buffer-bottom-MUST-temperature. In this case the required boiler temperature is the result of the
required buffer-bottom-MUST-tempe the adjusted temp. in the adjusted difference (see Fig.
8.5). In this is not the case, the required boiler temperature is the result of the required temperature + the
adjusted temp. increase (see Fig. 8.6). Caution: Consider the set minimum requirement.
