Data sheet LA 17TU
High-efficiency air-to-water heat pump with two performance levels
Max. flow temperature: 58 °C
Casing colour: White aluminium (similar to RAL 9006)
Heat pump for heating purposes for outdoor installation, with wall-mounted WPM
EconPlus heat pump manager and two compressors for output reduction when
operating at partial load. Sound-optimised through the use of slow-running 'owl's
wing' fans with a low natural sounding noise, an encapsulated compressor housing
with free-swinging compressor baseplate for solid-borne sound insulation. High
coefficients of performance (COP) through high-performance evaporator and
compliance with the requirements of EN 14511 for larger volume flows on the heat
consumption side. High operational safety through sensor monitoring of the
refrigeration circuit for energy-efficient defrosting; integrated thermal energy
metering (display of the thermal energy volume for heating and domestic hot water
preparation on the WPM EconPlus heat pump manager). Access for service work
on the outlet side; the minimum clearances must be observed for installation close
to walls. Universal design with two compressors for modulating operation, optional
domestic hot water preparation and flexible expansion options for:
- Bivalent or bivalent-renewable operating mode
- Distribution systems with unmixed and mixed heating circuits
- Use of load-variable tariffs (SG Ready)
Integrated flow and return sensors; external sensor (standard NTC-2) included in
the scope of supply.
Electrical connection cable EVL ..U between heat pump and heat pump
manager must be ordered separately.

Important information:
The combination of the components and the quantities indicated represent a non-binding sample system, which needs to be tested and individually
adapted as required. Pump dimensioning must be reviewed according to the pressure loss of the system and the minimum heating water flow rate of
the heat pump.

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.
