Circuit Setting range Factory setting
II ON / OFF OFF
If the flow or heating supply has to be limited, the number of heat
meters and their position must be determined.
ON: Two heat meters are used. This setting only
applies to heating system types 2, 2a, 3, 6,
and 6a with primarily connected DHW. The
heating supply or flow in circuit I (heating
circuit) is limited based on a signal from
heat meter 1. The same function applies to
circuit II (DHW) and heat meter 2.
OFF: One heat meter is used. This setting
especially applies to heating system types
with secondarily connected DHW, e.g.
heating system types 1, 4 und 5. However,
one heat meter can also be used for
heating system types 2, 2a, 3, 6, and 6a. For
these types the max. heating supply or the
max. flow is limited in parallel operation
from the heating or DHW circuit.
This function is only active when an M-Bus or the pulse module
ECA 84 / ECA 88 is connected. Other relevant settings are
described in the related instructions.
