Capacity limitation

The settings which are to made for the capacity limitation are mainly contained in function block FB31 as function block parameters. Only after selecting the type of limitation “At“ for outdoor temperature dependent limitation (which automatically means a 4-point characteristic), four outdoor temperature dependent maximum limits for heating need to be set in the 4-point char- acteristic menu. After selecting “- - -“, set Maximum limit for the system, Maximum limit for heat- ing and Maximum limit for DHW, Minimum limit and the Limiting factor that appear in this order. The Limiting factor determines how strongly the controller responds when the limit values are ex- ceeded in either direction.
