The setting is madeseparately for each heating circuit.The efficiency and convenient operation of theheating system significantly depend on theselection of the correct heating curve. If toohigh a heating curve is selected, the tempera-ture in the heating system will be excessive and,as a result, energy consumption will be higher. Ifthe selected heating curve is too low, thedesired temperature level may only be reachedafter a while or not reached at all.0,320 °C15 °C43 °C9.6 Menu C: Set parameters for the heating system
