Page 21: Curve
Settings Heating circuit 5.3 Curve Slope of the characteristic heating curve The characteristic curve is used to control the heat dissipation of the heating circuit re- lative to the outdoor temperature. The demand for heat is different due to differences in the type of building/insulation/type of heating/outdoor temperature. For this reason the controller can make use of a normal straight curve (Setting simple) or a split curve (Setting split). In the simple setting the curve can be adjusted with the help of the graphic diagram. The slope is changed, and the calculated reference flow temperature is displayed for -12 °C. If the split mode is selected, the characteristic curve is adjusted in 3 steps. First the stan- dard slope has to be set, after that the split point and finally the steepness of the curve after the split. -

Settings Heating circuit The following settings can be used for parallel translation of the characte- ristic for certain time periods such as daytime and nighttime mode. Caution 5.4 Day correction Parallel translation of the characteristic curve The day correction produces a parallel translation of the heating characteristic during the daytime operating hours, since depending on the outdoor temperature it is possible that the building may not be optimally heated with the set characteristic. If the charac- teristic is not optimised, the following situation may occur: in hot weather - the spaces are too cold in cold weather - the spaces are too hot In this case, one should gradually... -
Page 23: Reference/Actual
Settings Heating circuit 5.7 Reference/actual - Switch on hysteresis for additional heating This setting determines the allowed undershoot of the heat circuit temperature under the calculated reference flow temperature. If the heat circuit flow temperature falls below the reference temperature by this value, the additional heating (R5) is activated after a delay of 5 minutes. Settings range: -10°C to 10°C / Default: -2°C The additional heating (relais R5) is started when the flow temperature (in case of 2 heat circuits: one of the flow temperatures)is below the refe- rence flow temperature for 5 minutes continously. Caution 5.8 Reference/actual + Switch off hysteresis (only if S4 is connected) This settings determines the allowed overstepping of the heat circuit temperature to the calculated reference flow temperature at sensor 4. If the temperature at S4 exceeds the reference flow temperature by this value, the additional heating (R5) is switched off. -
