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.
