Parallel operation
Choose whether the heating circuit is to operate in dependence of the DHW
circuit. This function might be useful if an installation has limited power
or flow.
See Appendix "Parameter ID overview"
OFF: Independent parallel operation, i.e. the DHW and
the heating circuits operate independently of each
other. It makes no difference whether the desired DHW
temperature can be reached or not.
Value: Dependent parallel operation, i.e. the desired heating
temperature depends on the DHW demand. Choose
how much the DHW temperature can drop before the
desired heating temperature has to be decreased.

# 1#
# 2 # = Desired DHW temperature
# 3 # = Actual DHW temperature
# 4 # = Desired heating temperature
# 5 # = Reduced heating temperature
# 6 # = 100 % parallel operation
# 7 # = Parallel operation with decreased heating temperature
If the actual DHW temperature deviates more than the set value, the
gear motor M2 in the heating circuit will gradually close to such an
extent that the DHW temperature stabilizes at the lowest acceptable
value.
A377.2:
When parallel operation cannot be obtained, the circulation pump
in circuit 1 will be switched off.
