MENU > Settings > Return limit
Con.T, re. T lim. (Constant temperature mode, return
temperature limitation)
The "Con. T, ret. T limit" is the return temperature limitation value when the
circuit is set to override mode type "Const. T" (= Constant temperature).
See Appendix "Parameter ID overview"
Value: Set the return temperature limitation
MENU > Settings > Return limit
DHW, ret. T limit
When an addressed slave is active in DHW-tank heating / charging, the
return temperature limitation in the master can be set.
Notes:
• The master circuit must be set to react on the desired flow temperature
in the slave(s). See "Demand offset" (ID 11017).
• The slave(s) must be set to send its / their desired flow temperature to
the master. See "Send desired T" (ID 1x500).
See Appendix "Parameter ID overview"
OFF: No influence from slaves. The return temperature
limitation is related to settings in "Return limit".
Value: Return temperature limitation value when slave is in
DHW tank heating / charging operation.
MENU > Settings > Return limit
Limit (return temp. limitation)
Set the return temperature value you accept for the system.
See Appendix "Parameter ID overview"
When the return temperature falls below or gets higher than the
set value, the controller automatically changes the desired flow /
duct temperature to obtain an acceptable return temperature. The
influence is set in 'Infl. - max.' and 'Infl. - min.' .

The return temperature limitation for the DHW circuit is based on the
setting in 'Limit (return temp. limitation)' .
The influence factors are set in heating circuit 1.
