4.5 CE label
The CE label shows that the products
comply with the basic requirements of the
applicable directives as stated on the iden-
tification plate.
The declaration of conformity can be
viewed at the manufacturer's site.
4.6 Safety devices
4.6.1 Frost protection function
The frost protection function for the system
is controlled via the system controller. If
the system controller fails, the heat pump
guarantees limited frost protection for the
heating circuit.
4.6.2 Protection against low heating
water pressure
This function continuously monitors the
pressure of the heating water in order to
prevent a possible loss of heating water.
4.6.3 Brine loss protection system
The brine loss protection system continu-
ously monitors the fluid pressure in the
environment circuit in order to prevent a
possible shortage of fluid.
4.6.4 Freeze protection
This function prevents the evaporator from
freezing when the heat source temperat-
ure drops below a certain value.
The outlet temperature of the heat source
is constantly measured. If the outlet tem-
perature of the heat source falls below a
certain value, the compressor temporarily
switches off and displays a status mes-
sage. If this fault occurs three times in a
row, it is switched off and a fault message
is displayed.
4.6.5 Pump- and valve-blocking
protection system
This function prevents the pumps for heat-
ing water and brine and all diverter valves
from sticking. The pumps and the valves,
which were out of operation for 23 hours,
are switched on for 10 - 20 seconds, one
after the other.
4.6.6 High-pressure pressure switch
in the refrigeration circuit
The high-pressure pressure switch shuts
down the heat pump if the pressure in the
coolant circuit is too high. If the pressure
in the heat pump's refrigeration circuit ex-
ceeds the maximum pressure, the high-
pressure pressure switch temporarily shuts
down the heat pump. Following a waiting
period, another attempt is made to start
the heat pump. After three failed start at-
tempts in succession, a fault message is
displayed.
–Refrigeration circuit pressure max.: 4.60
MPa (g) (46.00 bar (g))
–Waiting period: 5 minutes (after the first
occurrence)
–Waiting period: 30 minutes
(after the second and every further oc-
currence)
The fault counter is reset if both of the
following conditions are met:
–Heat requirement without switching off
prematurely
–60 minutes of uninterrupted operation
4.6.7 Hot gas thermostat in the
refrigeration circuit
The hot gas thermostat shuts down the
heat pump if the temperature in the refri-
geration circuit is too high. If the temperat-
ure in the heat pump's refrigeration circuit
exceeds the maximum temperature, the
hot gas thermostat temporarily shuts down
the heat pump. Following a waiting period,
another attempt is made to start the heat

pump. After three failed start attempts in
succession, a fault message is displayed.
–Max. refrigeration circuit temperature:
135 ℃
–Waiting period: 5 minutes (after the first
occurrence)
–Waiting period: 30 minutes
(after the second and every further oc-
currence)
The fault counter is reset if both of the
following conditions are met:
–Heat requirement without switching off
prematurely
–60 minutes of uninterrupted operation
4.6.8 Safety cut-out (SCO) in the
heating circuit
If the temperature in the heating circuit of
the internal auxiliary electric heating ex-
ceeds the maximum temperature, the SCO
shuts down the auxiliary electric heating as
a securing measure. Following a waiting
period, another attempt is made to start
the auxiliary electric heating. A fault mes-
sage is displayed that can only be reset by
pressing the Reset button or by switching
the heat pump off and on again.

5.5 Starting up the product
▶Only start up the product once the cas-
ing has been completely closed.
5.6 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.
5.7 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.
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.
