» Air | water heat pump installed outdoors for heating and cool-
ing in new builds
» Inverter technology: Variable speed compressor for perfectly
matched heating output
» Compact outdoor unit can be combined with internal modules
thus reducing the amount of space required in the installation
room
» Low operating noise thanks to infinitely adjustable fan speed
and encapsulated refrigerant circuit
» ABC design –"anti-block condensate" prevents the condensate
drain from becoming blocked, which could result in the evap-
orator freezing
» Can be integrated into a home network and controlled via
smartphone
» High DHW convenience with large amount of mixed water due
to high flow temperature
» Straightforward hydraulic connection due to integral anti-vi-
bration mounts
Safety and quality
APPLICATION: Inverter air | water heat pump with output-de-
pendent control, designed as a mono block appliance for
compact outdoor installation. Can be used for heating and
DHW; also provides efficient cooling via circuit reversal. Ide-
ally suited for use in new builds or buildings with a low sys-
tem temperature. Sold in perfectly matched sets with com-
pact indoor units for straightforward, space saving installation.
EQUIPMENT/CONVENIENCE: Optimum noise reduction due to
encapsulated refrigerant circuit and isolated compressor. In
combination with the ISG (optional accessory), the heat pump
controller (included in the sets) can be used to control the sys-
tem via a home network or a mobile terminal device. With in-
tegral heat and electricity metering via refrigerant circuit data.
The refrigerant circuit is hermetically sealed, tested for tight-
ness at the factory and filled with safety refrigerant R410A.
EFFICIENCY: The waste heat from the inverter is used
to raise the return temperature, thereby increasing
the overall efficiency of the system. Demand-depend-
ent and energy efficient defrosting by reversing the circuit.
INSTALLATION: Accessories for effective drainage of any conden-
sate are available for both floor or wall mounted installations.
Integral anti-vibration mounts for direct connection to the heat-
ing system. Easy access to the electrical connection panel without
having to open the appliance.
Function
Heat is extracted from the outdoor air via the heat exchanger
(evaporator) on the air side across its entire operating range.
The heating water is heated to the flow temperature in the heat
exchanger on the water side (condenser) using electrical ener-
gy (compressor). At low air temperatures, the humidity in the air
precipitates as hoarfrost on the evaporator fins. This hoarfrost is
automatically defrosted. The accumulating water flows out of the
appliance via the condensate drain in the floor of the appliance
and seeps away into the gravel bed. The energy required for de-
frosting is drawn from the heating system. The heat pump auto-
matically reverts to heating mode at the end of the defrost cycle.
The heat pump manager and output control function match the
heat pump heating output variably to the actual heat demand.
In cooling mode, heat is extracted from the heating water via the
heat exchanger on the heating side. The refrigerant is heated fur-
ther by electrical energy (compressor) and gives off this heat to
the outdoor air via the heat exchanger on the air side.

SET COMPONENTS: Heat pump from the classic range and
HSBC 200 integral cylinder including DHW cylinder with inter-
nal indirect coil, WPM heat pump manager, cylinder charging
pump, heating circuit pump, 3/2-way diverter valve, safety valve,
100l parallel buffer cylinder and electric emergency and booster
heater.
APPLICATION: Inverter air | water heat pump with output-de-
pendent control, designed as a mono block appliance for compact
outdoor installation. Can be used for heating and DHW; also pro-
vides efficient cooling via circuit reversal. Ideally suited for use in
new builds or buildings with a low system temperature. Sold in
perfectly matched sets with compact indoor units for straightfor-
ward, space saving installation.
EQUIPMENT/CONVENIENCE: Optimum noise reduction due to en-
capsulated refrigerant circuit and isolated compressor. With inte-
gral heat and electricity metering via refrigerant circuit data.
EFFICIENCY: The waste heat from the inverter is used to raise the
return temperature, thereby increasing the overall efficiency of
the system. Demand-dependent and energy efficient defrosting
by reversing the circuit.
INSTALLATION: Required accessories for effective drainage of any
condensate are available for both floor or wall mounted instal-
lations. Integral anti-vibration mounts for direct connection to
the heating system. Easy access to the electrical connection panel
without having to open the appliance.
Function
Heat is extracted from the outdoor air via the heat exchanger
(evaporator) on the air side across its entire operating range.
The heating water is heated to the flow temperature in the heat
exchanger on the water side (condenser) using electrical ener-
gy (compressor). At low air temperatures, the humidity in the air
precipitates as hoarfrost on the evaporator fins. This hoarfrost is
automatically defrosted. The accumulating water flows out of the
appliance via the condensate drain in the floor of the appliance
and seeps away into the gravel bed. The energy required for de-
frosting is drawn from the heating system. The heat pump auto-
matically reverts to heating mode at the end of the defrost cycle.
The heat pump manager and output control function match the
heat pump heating output variably to the actual heat demand.
In cooling mode, heat is extracted from the heating water via the
heat exchanger on the heating side. The refrigerant is heated fur-
ther by electrical energy (compressor) and gives off this heat to
the outdoor air via the heat exchanger on the air side.
