4.10 Operating levels
The product has two operating levels.
The operating level for the operator shows
the information and offers set-up options
that do not require any special prior know-
ledge.
The operating level for the competent per-
son is protected by a code.

5 Operating
5.1 Starting up the product
▶
Only start up the product once the cas-
ing has been completely closed.
5.2 Adjusting the target cylinder
temperature
In order to achieve energy-efficient hot
water generation predominantly from the
energy extracted from the environment,
the factory setting for the desired hot water
temperature must be adjusted on the sys-
tem controller.
▶
To do this, adjust the cylinder set target
temperatures (Desired DHW circuit
temperature) to between 50 and 55 °C,
for example.
◁
Depending on the source of energy
obtained from the environment,
hot water output temperatures of
between 55 and 62 °C are reached.
5.3 Yield indicator
Displays the environmental energy yield as
a cumulative value for a period of a day,
a month and the total for the heating, hot
water generation and cooling modes.
Displays the working figure for a period of
a month and the total for the heating and
hot water generation modes. The work-
ing figure is the ratio of thermal energy
generated to the operating current used.
12
Monthly values may vary considerably
since, for example, in the summer only
hot water generation is used. A large num-
ber of factors influence this estimate, e.g.
the type of heating installation (direct heat-
ing mode = low flow temperature or indir-
ect heating mode via buffer cylinder = high
flow temperature). This figure may there-
fore deviate by up to 20%.
The working figures only record the power
consumption of internal components, not
of external components such as external
heating circuit pumps, valves, etc.
