OPERATION
Appliance description
3.
Appliance description
This appliance enables DHW to be supplied efficiently to several
draw-off points using renewable energy. The appliance extracts
heat from the ambient air. This heat is used to heat up the water
in the DHW cylinder with added electric power. The amount of
electrical energy and time required to heat up the hot water depend on the temperature of the air drawn in and the temperature
of the water in the cylinder. When the air intake temperature
drops, the appliance heating output is reduced and the heat-up
time is extended.
Subject to the power supply and user draw-off behaviour, the
water is heated automatically to a temperature that is set at the
factory.
In the case of indoor installation, the air inside the installation
room can be cooled by 1 °C to 3 °C due to heat extraction. The
appliance also extracts moisture from the air, which turns into
condensate. The condensate is removed from the appliance via
the condensate drain.
The heat pump drive unit is located in the upper section of the
appliance. The DHW cylinder is located in the lower section of the
appliance. To protect against corrosion, the DHW cylinder is coated
internally with special enamel and is additionally equipped with
a non-sacrificial impressed current anode.
3.1
Heat pump operating principle
The energy (motor heat) is not lost, but reaches the downstream
condenser together with the compressed refrigerant. There, the
refrigerant transfers heat to the DHW cylinder. An expansion valve
then reduces the still prevalent pressure and the cyclical process
starts again.
DHW heating
1
1 Cylinder top sensor
2 Integral sensor
The appliance is equipped with two temperature sensors.
-- The cylinder top sensor captures the water temperature in
the upper section of the cylinder.
-- The integral sensor is a temperature sensor affixed all the
way down the cylinder. The integral sensor determines the
average cylinder temperature.
6 | WWK 222-302 H
Note
If the appliance has been isolated from the power supply
during operation, the compressor will only restart after
the pressure inside the refrigerant circuit has been equalised. Pressure compensation can take several minutes.
WWK 222 H | WWK 302 H: Electric emergency/booster heater
When the temperature in the upper section of the DHW cylinder
drops 10 K below the selected set temperature, the appliance
automatically switches on the electric emergency/booster heater.
When the temperature in the upper section of the DHW cylinder
rises 2 K above the selected set temperature, the appliance switches off the electric emergency/booster heater.
3.3
Appliance operation outside the application
limits
Outside the application limits, the appliance blocks the compressor from operating. This could lead to reduced DHW convenience.
If the appliance has an electric emergency/booster heater, this will
be enabled if a demand for heating up the water exists and the
lower application limit is underrun.
Low ambient temperatures may result in the formation of hoar
frost on the evaporator depending on the air humidity and water
temperature.
Active defrost feature
The appliance is equipped with active hot gas defrosting, which
allows quick defrosting of the evaporator when needed. During
defrosting, the appliance fan is deactivated. The compressor continues to run. A solenoid valve routes the hot gas directly to the
evaporator. While this is happening, refrigerant flow to the condenser is disabled by another solenoid valve.
In contrast to conventional defrosting methods, the appliance
guarantees that defrosting takes place only when needed.
D0000050335
2
DHW is normally heated by the heat pump of the appliance (see
chapter "Specification / Data table").
3.3.1 Ambient temperatures below the application limit
A closed circuit within the appliance contains refrigerant (see
"Specification / Data table"). This refrigerant evaporates at low
temperatures. In the evaporator, which extracts heat from the
air drawn in, the refrigerant changes from a liquid into a gaseous state. A compressor draws in the gaseous refrigerant and
compresses it. This increase in pressure raises the refrigerant
temperature. That requires electrical energy.
3.2
The appliance control unit uses the average cylinder temperature
captured by the integral sensor. DHW heating is started when the
average cylinder temperature falls below the set temperature.
Note
Heat-up times are longer while the evaporator is defrosting.
3.3.2 Ambient temperatures above the application limit
Outside the application limits, the appliance blocks the compressor from operating.This could lead to reduced DHW convenience.
If the appliance has an electric emergency/booster heater, this
will be enabled if a demand for heating up the water exists and
the upper application limit has been exceeded.

OPERATION
Settings
3.4
Frost protection
The appliance activates the frost protection function if the integral
sensor in the DHW cylinder captures a temperature below 8 °C.
The appliance then heats the water by means of the heat pump
and the electric emergency/booster heater. The heat pump and
electric emergency/booster heater switch off when the temperature captured by the integral sensor reaches 16 °C.
3.5
!
Minimum runtime and minimum pause time
Material losses
When operating with external switching devices that can
interrupt the power supply to the appliance, such as time
switches, energy management systems or home automation systems, observe the following conditions:
-- The minimum ON time is 60 minutes.
-- The minimum pause time following a shutdown is
20 minutes.
-- The appliance should not be switched on/off more
than 10 times per day.
-- The breaking capacity of the switching element must
meet the fuse rating requirements (see chapter
“Specification / Data table”).

Troubleshooting
Protective anode and battery replacement
The appliance is equipped with a maintenance-free impressed
current anode that protects the cylinder from corrosion when it
is connected to the power supply. At the factory, the appliance is
fitted with rechargeable batteries that ensure the power supply
to the impressed current anode in the case of a power failure. The
power supply to the appliance must not be interrupted for more

Reconnect the earth cable to the casing ring.
14.5 Descaling the electric emergency/booster
heater
D0000034814
Only descale the flange of the emergency/booster heater after
disassembly. Never treat the inside of the DHW cylinder or the
impressed current anode with descaling agents. The electric
emergency/booster heater is screwed into the DHW cylinder of
the appliance at a central point at the top.
ff
Fit the upper casing ring. The casing ring overlaps along the
joint. A tab on one end clips into the recess at the other end
of the casing ring.
ff

14.10 Protective anode and battery change
The appliance is equipped with a maintenance-free impressed
current anode that protects the cylinder from corrosion when it
is connected to the power supply. At the factory, the appliance is
fitted with rechargeable batteries that ensure the power supply
to the impressed current anode in the case of a power failure.
The power supply to the appliance must not be interrupted for
more than 16 hours.
If the power supply is regularly interrupted by a switching contact
or the security of supply is inadequate, the rechargeable batteries
of the impressed current anode must be replaced every three
years. Neglecting to do this puts the appliance at risk of damage.
If regular interruptions in the power supply are not anticipated
and there is security of supply, no maintenance of the batteries
is required and the appliance is maintenance-free in this regard.

15.4.1 Standardised output data
Explanations to determine and interpret the specified standardised
output data
Standard: EN 16147
The output data specifically mentioned in text, diagrams and
technical datasheets has been determined in line with the test
conditions described in the standard shown in the heading of
this chapter.
Generally, these standardised test conditions will not fully meet
the conditions found at the installation site of the system user.
Depending on the chosen test method and the extent to which
the selected method deviates from the conditions described in the
standard shown in the heading of this chapter, any deviations can
have a considerable impact. Further factors that have an influence
on the test values are the measuring equipment, the system configuration, the age of the system and the flow rates.
A confirmation of the specified output data can only be obtained
if the conditions applicable to the relevant test match those of the
standard shown in the heading of this chapter.
