System settings (Service menu – Settings) 6.4.3 Heating curve Parameter: design temperature, maximum and minimum flow temperature and room temperature offset (parallel shift). The heating curve is the decisive basic factor for an economic and convenient operation of the heating system with outside temperature compensated control. For the calculation of this curve the Logamatic control system requires information about some of the heating system characteristics, and from this it calculates automatically and by means of a mathematical formula the optimum heating curve. -
