− Max. limit value to determine the absolute upper limit
− Max. limit value for heating to operate room heating only
− Max. limit value for DHW to operate DHW heating only
If the 'Max. limit value for heating' parameter is set to 0.00 or 0.0, a four-point characteris-
tic congured in CO1 > F11-1 allows the input of four ow rate or capacity limits in addi-
tion to the outdoor, ow and return ow temperature values.
In all systems without DHW heating or without heating circuit, only the max. limit value for
the ow rate or capacity can be specied. In all systems with two control valves, separate
maximum limits can be adjusted for the ow rate and capacity.
Note:
Since only the 'Max. limit value for heating' can be set to 0.00 or 0.0, a system with
DHW heating must be congured even if a DHW heating is not used to allow the pa-
rameterization of a weather-compensated ow rate or capacity limitation. For exam-
ple, system Anl2.0 with a deselected storage tank sensor would need to be cong-
ured in place of system Anl1.0.
Flow limitation
All settings required to set up ow rate limitation are available in CO6 > F11 or CO6 > F13
for systems with two control valves. One after the other, the system's max. limit value and –
for systems with only one control valve and DHW heating on the secondary side – the max.
limit value for heating and the max. limit value for DHW have to be set. The 'Limiting factor'
determines how strongly the controller responds when the limit values are exceeded in either
direction.
NOTICE
If the controller indicates CO5>F00 - 1, any access to the return ow, ow rate and
capacity settings is locked.
