The following values are displayed per entry:
- Fixed day (storage date))
- Yearly performance factor
- Supplied heat for heating
- Supplied heat for DHW
- Employed energy for heating
- Employed energy for DHW
Displayed are the supplied and used energy values over the course of a year (or
between two fixed day entries).
The fix day storage can be deleted as a whole (all entries) via parameter 3190.

Fixed day yearly performance factor
Fixed day yearly performance factor
The parameter
Fixed day yearly perf fact
sets the fixed day (day / month).
An entry is generated in the storage at mid-night of the entered, fixed day. The process
is repeated annually. The fixed day cannot be deactivated.
Counter values
The counter values displayed in the fixed day storage are the energy values recorded
over the time period between the two fixed day entries which are used to calculate the
associated yearly performance factor.
Supplied and employed energy for heating and DHW is displayed separately.
Up to 10 entries (10 years) can be stored in the fixed day storage. The first entry (Index
1) is always the latest and drops the older entries in the index by one position. The
counter value "---" is displayed if the storage entry is empty.

The performance factor and yearly performance factor are
based on the following definitions:
Yearly performance factor
The yearly performance factor is a quotient from supplied energy (E
ab
) and employed
energy (E
ein
) over a period of one year. The gain consists for the energy derived from
the environment (E
um
).
