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.
# 1 # = Master, example A266, address 15
# 2 # = Slave, example A237, address 9
# 3 # = Slave, example A367, address 6
Some examples of applications with DHW-tank heating / charging are:
