The heating system’s solar thermal
system has to be configured manu-
ally. Automatic configuration of the
heating system (
Æ
Section 8.2,
page 56) does not configure the
solar system.
An example system configuration is
shown in Section 2.6 on page 11.
Fill and bleed the solar thermal sys-
tem according to its documentation
and prepare it for commissioning as
described this Section.
The designations of the pumps and
the temperature sensors, e.g. (PE)
or (T1), are also used in the ISM in-
stallation instructions.
