Temperature manager TEMPERATURE MANAGER The heat demand of the individual modules (boiler, hot water tank, heating circuit, solar, etc.) is controlled by the temperature manager. The below-mentioned scheme explains the functionality of the temperature manager. From the individual modules the MUST-temperature is determined and to that an adjustable temp. increase is added.
Page 15
Temperature manager If the required buffer-top-temperature (required temperature) is higher than the sum of buffer-bottom-MUST- temperature and the set difference, then the required boiler temperature is the result of the required buffer- top-temperature (required temperature) + the adjusted temp. increase (see fig. 8.2) Caution: Consider the set minimum requirement Fig.
Page 16
Temperature manager 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).
