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

influence is set in 'Infl. - max.' and 'Infl. - min.' .
MENU > Settings > Return limit
