High-efficiency air-to-water heat pump
Max. flow temperature: 60 °C
Casing colour: White (similar to RAL 9003)
Brown-red design screen (RAL 3011)
The new high-efficiency heat pumps for indoor installation feature a flexible air
circuit and a simple hydraulic connection. The outside air is drawn in at the back of
the device. No air ducts are required. Thanks to the EC 3D radial fan, the air outlet
can be on the left, right or top of the casing (as needed). The hydraulic connection
of the heat pump can be perfectly adjusted to the given conditions. For installation,
the flow and return can lead into the casing from the left or the right, as required.
The benefits at a glance:
- Variable air outlet to the left, right or top with the
- option of relocating the hydraulic connections from the right to the left
- Electronic expansion valve for high seasonal performance factors and low operating
costs
- Free-swinging compressor baseplate and slow-running EC radial fan for low noise
emissions
- WPM EconPlus heat pump manager with integrated thermal energy metering and
flow switch for high operational safety
- Compact dimensions for space-saving installation - installation with built-under
buffer tank PSP 120E possible

Air-to-water heat pump, Integration Diagram, Heat pump and immersion heater
System description:
Presettings:
• Air-to-water heat pumps with defrosting by reverse circulation extract the energy required for defrosting from the heating system. In the case of
air-to-water heat pumps, a buffer tank connected in series, into which the immersion heater is screwed, must be installed in the flow in mono
energy systems to ensure defrosting. A dirt trap with a mesh size of between 0.6mm and 0.8mm is to be installed in order to protect the plate
heat exchanger from larger dirt deposits. Clean the filter sieve of the dirt trap one day after start-up. These intervals can be extended as soon as
no more impurities are detected. When the level of impurities is significantly high (e.g. due to corrosion found in the building), it is recommended
that a sludge trap be installed in order to minimise the need for regular cleaning. A permanent corrosion process, caused by the entry of oxygen
into the system, is characteristic of heating systems featuring open diffusion. This is best alleviated using an electrophysical anti-corrosion
system. Condensate which forms during defrosting must be drained off without risk of frost. Acoustic emissions must be taken into account, and
a free air circuit provided for, when the installation location is being selected. Heat pumps without weather-proof protective covers in particular
need to be installed outdoors in such a manner that the air outlet is not positioned against the main wind direction.
• A buffer tank connected in series is recommended for heat pump heating systems, to ensure the minimum heat pump runtime of 6 minutes for all
operating statuses.

• The heat pump supplies a large part of the required heat output. An electric heating element (immersion heater) supplements the heat pump on days when the external temperature lies below the bivalence point. In mono energy
systems, the contactor for the immersion heater (E10.1) must be set according to the output. It is controlled (230 V AC) by the heat pump manager via terminals X1/N and J13/NO4.
• The heat exchanger in the hot water cylinder must transfer the maximum heat output at the maximum heat source temperature. In systems with high hot water consumption (multiple dwellings, industrial applications) the cylinder must be
set to the maximum peak demand while taking the shut-off times into account. The maximum heat output and the maximum heating water flow must be adhered to!
• The contactor for the flange heater (E9) in the hot water cylinder should be dimensioned according to the output and must be supplied by the customer. It is controlled (230 V AC) by the heat pump manager via terminals X1/N and
J16/NO10. The maximum heat output of the heat pump and the water flow are to be observed.
• The dual differential pressureless manifold ensures that the required minimum water flow rate is maintained, independent of both the number of open heating circuits and of how the system is used. Hydraulic isolation is carried out using
two connections between flow and return; each connection is fitted with a check valve. The characteristic curve of the pump in the consumer circuit must be set in such a way that a maximum spread of 10 Kelvin is not exceeded, in order
to prevent unnecessary surging of the heat pump. Electronically regulated pumps must be operated at a constant pressure.
