  • Page 34 Target temperature When the Target temperature function is acti- vated, the pump speed control logic changes. The controller will remain at the minimum pump speed until the temperature at the allocated sensor exceeds the adjusted target temperature. Only then will the standard pump speed control start to operate.
  • Page 35 Afterheating suppression The afterheating suppression blocks the conventional afterheating of a store that is currently in solar loading. This function is activated if a previously selected Store is being loaded. Solar loading means that store loading is only carried out for energy supply and not for cooling purposes etc. If the Tset option is activated, the afterheating will only be suppressed when the store temperature ex- ceeds Tset.
