CleverCharge – he smart buffer control module for your T-Control 7“ system

With the CleverCharge buffer controlGive your core system a mind of its own!

In cooperation with the Technology and Research Center BEST – Bioenergy and Sustainable Technologies GmbH, a development project was carried out to increase the comfort of Herz biomass systems. The factory-integrated CleverCharge buffer control module enables your Herz system to operate more efficiently and adapt optimally to consumer demand. In addition to enhancing comfort when heating with wood, it helps reduce fuel consumption and emissions.

The great advantages:

  • No hardware modifications required
  • The system learns consumer behavior and can therefore be controlled more efficiently.
  • Continuous availability of heat through consumption estimation via temperature sensors (taking weather forecasts into account).
  • Maximum utilization of solar yield thanks to weather forecasting and intelligent calculation.
  • Modulating boiler output, which avoids constant system start/stop cycles and reduces fuel consumption and emissions.
  • Also responds to increased hot water demand.
  • Reduced or no unnecessary boiler running times, ensuring the buffer tank is fully charged

Possible operating modes for ‘CleverCharge’ operation:

  • ECO

    • Economical operation with reduced fuel consumption: the buffer tank is almost completely emptied.
    • The system starts at a later time, which means that continuous heat from the buffer tank cannot be guaranteed.
  • Comfort

    • Boiler operation with higher fuel consumption: the buffer tank is not completely emptied.
    • The system or buffer tank charging process starts earlier so that the buffer tank can always provide heat.
  • Standard

    • Standard operation for buffer tank charging based on consumer demand calculation.“
Display: Boiler output with and without CleverCharge

he blue curve indicates that the boiler is either off or operating at full load. With CleverCharge (orange curve), a longer runtime is visible due to earlier start-up and later shut-down. During operation, the boiler modulates its output, making full use of its performance range.

Display: Average buffer tank temperature with and without CleverCharge

The blue curve shows that the buffer tank is discharged to a low temperature level and then recharged to a very high level when needed. With CleverCharge (orange curve), the buffer tank maintains a much more consistent temperature, preventing it from being completely emptied or overfilled.
