Time program 3/HC3
DHW release
Time program 4/DHW
Time program 5
The circulating pump runs during the release time (see below), provided DHW heating
is On and at least one of the connected heating circuits is not in Holiday mode. If DHW
mode is Off, or if all connected heating circuits are in Holiday mode, the circulating
pump remains deactivated, independent of the parameterized release. Release of the
circulating pump can take place in different ways:
Time program 3/HC3
The circulating pump is released according to Time program 3/Heating circuit 3.
DHW release
When using this setting, the circulating pump is released when DHW heating is
released also.
Note!
Release of DHW heating can be set with a specific release parameter.
Time program 4/DHW
The circulating pump is released according to Time program 4/DHW.
Time program 5
The circulating pump is released according to Time program 5.
