Standardised output data
Information on determining and interpreting the specified standardised output data.
1.5.1 EN 14511
The output data specifically mentioned in texts, diagrams and
technical datasheets has been calculated according to the test
conditions of the standard shown in the heading of this section.
However, there is a deviation from this norm in the output data for
air/water inverter heat pumps at source temperatures of > -7 °C
as this concerns partial load values. The associated percentage
weighting in the partial load range can be found in EN 14825 and
EHPA quality label regulations.
Generally, the test conditions stated above will not fully match the
conditions found at the installation site of the system user.
Depending on the chosen test method and the extent to which
this method deviates from the test conditions defined in the first
paragraph of this section, any deviations can have a considerable
impact.
Additional 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.
Confirmation of the specified output data can only be obtained,
if the test conducted for this purpose is also performed in accordance with the test conditions defined in the first paragraph
of this section.

Appliance description
The appliance is an air|water heat pump that operates as a heating heat pump. Heat is extracted from the outdoor air at a low
temperature level, and is then transferred to the heating water at
a higher temperature. The heating water can be heated up to a
flow temperature of 75 °C.
With the appropriate accessories, this appliance may be installed
internally or externally.
The appliance is equipped with an electric emergency/booster
heater (DHC). If the dual mode point is undershot in mono mode
operation, the electric emergency/booster heater is activated to
safeguard heating operation and the provision of high DHW temperatures. If the same thing happens in mono energetic operation,
the electric emergency/booster heater is activated as a booster
heater.
Operational characteristics:
-- Suitable for underfloor and radiator heating systems
-- Still extracts heat from the outdoor air at – 20 °C outdoor
temperature.
-- Corrosion-protected, external casing made from zinc-plated
sheet steel plus powder-coated finish.

Operation
Settings
-- Comprises all components and safety equipment required for
operation.
-- Filled with non-combustible safety refrigerant.
ff
Once a month, check that the condensate drain is working correctly (visual inspection). When doing so, check for
water collecting below or next to the appliance. See chapter
“Troubleshooting”.
Note
To control the heating system, you will need the heat
pump manager “WPM”.
3.1
Function
Heat is extracted from the outdoor air via the heat exchanger
(evaporator) on the air side. The now evaporated refrigerant is
compressed with one or two compressors. This process requires
electrical energy. Now, the refrigerant is at a higher temperature
level and transfers the heat drawn from the air via an additional
heat exchanger (condenser) to the heating system. The refrigerant
then expands again and the cycle restarts from the beginning.
At air temperatures below approx. +7 °C, the humidity in the air
condenses as hoarfrost on the evaporator fins. This hoarfrost is
automatically defrosted. Water created by this defrosting process
collects in the defrost pan and is drained off via a hose.
!
Material losses
In the defrost cycle, the fan is switched off and the heat
pump circuit is reversed. The heat required for defrosting
is drawn from the buffer cylinder.
For operation without a buffer cylinder, observe the information in the WPM instruction manual and the BUFFER OPERATION parameter in the SETTINGS / STANDARD
SETTING menu.
Otherwise the heating water freezes under unfavourable
conditions.
Material losses
Keep the air discharge and intake apertures free from
snow and leaves.
We recommend regular inspection (to establish the current condition of the system), and maintenance by a qualified contractor
if required (to return the system to its original condition).

INSTALLATION
7.3
Operation of the appliance in buildings with
combustion equipment
As the appliance can produce negative pressure in the installation room, we recommend using a tightly sealing door between
the installation room and the living space containing combustion
equipment.
If, due to its use, the installation room is connected to the extract air system, you must also allow for a supply air valve in the
installation room in this particular case to prevent any further
increase in the negative pressure in the installation room. The
negative pressure created by the appliance in the installation room
is heavily influenced by the pressure drop in the outdoor air line.
For this reason, the outdoor air line in particular should be as
short as possible.
8.
Appliance description
For outdoor installation the appliance offers additional frost protection of the heating water pipes. The integral frost protection
circuit starts the circulation pump in the heat pump circuit automatically at +8 °C condenser temperature, and thereby ensures
circulation in all water-filled sections. The heat pump is started
automatically no later than when the temperature inside the buffer
cylinder drops below +5 °C.

Installation
Preparation
ff
Protect the flow and return lines against frost with sufficient
thermal insulation. The thermal insulation must be at least
twice as thick as the diameter of the pipe. Provide thermal
insulation in accordance with applicable regulations.
Note
When routing the condensate hose, observe chapter “Installation / Condensate drain”.
ff
Isolate the installation surface around the heat pump by
means of a recess. After completing the installation, seal the
recess with a water-impervious and sound insulating material, such as silicone for example.
Observe the following information:
-- Connect the heating circuit flow and return lines via flexible
pressure hoses. Suitable pressure hoses are listed in chapter "Appliance description / Required accessories for indoor
installation".
9.3.2 Indoor installation
Material losses
The installation room floor must be water resistant. During appliance operation, the outdoor air releases up to
50 l of condensate per day. If humidity levels in the installation room are high, condensate may form on the
appliance and air hoses. If the condensate drain is not
installed correctly or if maintenance is not carried out
properly, water may leak out. We recommend installing
a drain in the floor of the installation room.
!
The room where the appliance is installed must meet the following
conditions:
-- No risk from frost
-- The room must not be subject to a risk of explosions arising
from dust, gases or vapours.
-- If installing the appliance in a plant room together with other
heating equipment, ensure that the operation of other heating equipment will not be compromised.
-- Minimum volume of the installation room. The minimum
volume of the installation room is assured if the minimum
clearances are observed.
-- Load bearing floor (for the weight of the appliance, see chapter “Specification / Data table”).
ff
For installation on floating screeds, make provisions for quiet
heat pump operation.

10.5 Oxygen diffusion
!
In underfloor heating systems with plastic pipes that are permeable to oxygen and in open vented heating systems, oxygen
diffusion may lead to corrosion on the steel components of the
heating system (e.g. on the indirect coil of the DHW cylinder, on
buffer cylinders, steel radiators or steel pipes).
ff
With heating systems that are permeable to oxygen, separate
the heating system between the heating circuit and the buffer cylinder.

Material losses
Avoid open vented heating systems and underfloor
heating systems with plastic pipes that are permeable
to oxygen.
Material losses
The products of corrosion (e.g. rusty sludge) can settle in the heating system components, which may result in a lower output or fault shutdowns due to reduced
cross-sections.

10.6 Filling the heating system
10.7 Minimum flow rate
Heating water quality
The minimum flow rate and the defrost energy must always be
assured (see chapter “Specification / Data table”).
Carry out a fill water analysis before filling the system. This analysis may, for example, be requested by the relevant water supply
utility.
10.8 Setting the flow rate on the heating side
To avoid damage as a result of scaling, it may be necessary to
soften or desalinate the fill water. Always observe the fill water
limits specified in the "Specification / Data table" chapter.
ff
Recheck these limits 8-12 weeks after commissioning and as
part of the annual system maintenance.
Note
With a conductivity > 1000 μS/cm, desalination treatment
is recommended in order to avoid corrosion.
Note
If you treat the fill water with inhibitors or additives, the
same limits apply as for desalination.
Note
Suitable appliances for water softening, as well as for
filling and flushing heating systems, can be obtained via
trade suppliers.
!
Material losses
For operation without a buffer cylinder, it is essential
that the electric emergency/booster heater (DHC) is connected.
The appliance is designed in such a way that no buffer cylinder
is required to provide hydraulic separation of the flow in the heat
pump circuit and the heating circuit in conjunction with area heating systems.
We recommend the use of a buffer cylinder for installations with
several heating circuits.
You can set the flow rate in heat pump mode. In order to do this,
firstly make the following settings:
ff
Temporarily remove the fuse from the electric emergency/
booster heater to isolate the emergency/booster heater from
the power supply. Alternatively, switch OFF the second heat
generator.
ff
Operate the appliance in heating mode.
10.8.1 Minimum flow rate with individual room control via
remote control in systems without buffer cylinder
Venting the heating system
ff
Vent the pipework carefully. For this, also activate the air
vent valve integrated into the heating flow inside the heat
pump.
For systems without a buffer cylinder, in the "SETTINGS / HEATING / STANDARD SETTING" menu, set the "BUFFER OPERATION"
parameter to "OFF".
In such cases, one or more heating circuits in the heating system
must be left open. Ensure the minimum flow rate (see "Specification / Data table") by means of the correspondingly opened heating
circuits (see table "Design recommendation for underfloor heating
system in the lead room").

the room influence.
ff
Fully open the heating circuit(s) in the lead room.
ff
Close all other heating circuits.
ff
If an overflow valve has been installed in the heating system,
fully close this overflow valve in order to determine the minimum flow rate.
In combination with an HM hydraulic module:
ff
Under menu item “COMMISSIONING / HEATING” set the parameter “HEATING CIRC PUMP RATE” (heating circuit pump
rate) so that the minimum flow rate required for system operation is assured (see chapter “Specification / Data table”).
If the appliance is operated on its own with a WPM:
ff
Set the heating circuit pump so that the minimum flow rate
required to operate the system is safeguarded.
The current flow rate can be called up in the menu "INFO / HEAT
PUMP INFO / PROCESS DATA" under "WP WATER FLOW RATE".
10.8.2 Minimum flow rate for systems with a buffer cylinder
When using a buffer cylinder, in menu "SETTINGS / HEATING /

10.11 Condensate drain
A hose is fitted at the factory to the defrost pan to act as condensate drain. The hose terminates near the knock-out on the bottom
plate to the right of the refrigeration drive.
Material losses
Ensure the hose is not kinked. Route the hose with a
slope.
Use a suitable condensate pump if there is insufficient fall. Observe
the delivery head of the building.
Outdoor installation
ff
Route the hose downwards out of the appliance. The condensate hose can also be routed out of the appliance to the right
through the knock-out in the side panel.
ff
Channel the condensate into a drain or allow it to drain into a
coarse gravel soakaway. Ensure the pipework is free from the
risk of frost.
If required, you may install a ribbon heater on the condensate
hose. We recommend that you install a ribbon heater if the routing of the condensate hose means it is at risk of frost or is fully
exposed to the elements. The ribbon heater is switched on at a
temperature < 0 °C.
ff
Observe the chapter "Electrical connection".
Indoor installation
ff
Route the condensate into a drain. For this, route the hose
through an opening in the floor plate and frame, and route it
out of the appliance to the right by removing the knock-out in
the bottom of the side panel.
In the following diagram the position of the knock-out for the
condensate hose can be seen.

10.9 Heat meter
Material losses
When installing a heat meter, note that most heat meters cause a substantial pressure drop, and therefore you
should select a larger circulation pump.
10.10 High limit safety cut-out for underfloor heating
systems
Material losses
In order to prevent excessively high flow temperatures
in the underfloor heating system causing damage in the
event of a fault, we always recommend using a high limit
safety cut-out to limit the system temperature

14. Commissioning
A WPM heat pump manager is required to operate the appliance.
All necessary adjustments prior to and during operation are made
on this device.
Only qualified contractors may make the settings in the heat pump
manager commissioning report, commission the appliance and
instruct the owner in its use.
Commissioning is to be carried out in accordance with these installation instructions and the operating and installation instructions
of the heat pump manager. Our customer support can assist with
commissioning, which is a chargeable service.
Where this appliance is intended for commercial use, the regulations of the relevant Health & Safety at Work Act may apply during
commissioning. For further details, check your local authorising
body.

14.1.4 Power supply
-- Have you correctly connected the power supply?
14.2 Settings
14.2.1 Heating curve adjustment
The efficiency of a heat pump decreases as the flow temperature
rises. The heating curve should therefore be adjusted with care.
Heating curves that are set too high cause the zone valves or thermostatic valves to close, which may lead to the minimum flow rate
required for the heating circuit not being achieved.
ff
Observe the WPM operating and installation instructions.
The following steps will help you to adjust the heating curve correctly:
-- Fully open thermostatic or zone valves in a lead room (e.g.
living room and bathroom).
We do not recommend installing thermostatic or zone valves
in the lead room. Control the temperature for these rooms
via remote control.
-- At different outside temperatures (e.g. -10 °C and +10 °C),
adjust the heating curve so that the required temperature is
set in the lead room.

(approx. 10 °C outside temperature), raise the “COMFORT TEMPERATURE” parameter in the heat pump manager menu under
“SETTINGS / HEATING / HEATING CIRCUIT”.
14.1.3 High limit safety cut-out
At ambient temperatures below -15 °C it is possible that the high
limit safety cut-out of the electric emergency/booster heater may
trip.
ff
Check whether the high limit safety cut-out has tripped.
Note
If no remote control is installed, raising the "COMFORT

Appliance shutdown
Increase the “HEATING CURVE” parameter, if the room temperature is not high enough when outside temperatures are low.
If the "HEATING CURVE" parameter has been raised, in the case of
high outside temperatures, adjust the zone valve or thermostatic
valve in the lead room to the required temperature.
Note
Never reduce the temperature in the entire building by
closing all zone or thermostatic valves, instead use the
setback programs.
When everything has been implemented correctly, the system
can be heated to its maximum operating temperature and vented
once again.

after the bus address has been assigned successfully. Only then
has communication with the WPM been established.
16.1.2 Reset button
If the IWS was incorrectly initialised, the settings can be reset with
this button. For this, also observe chapter "Reinitialising the IWS"
in the heat pump manager operating and installation instructions.
16.2 Resetting the high limit safety cut-out
The electric emergency/booster heater (DHC) stops if the heating
water temperature exceeds 85 °C on account of a low flow rate.
ff
Remove the cause of the fault.
If the appliance is operated in dual mode with a second heat
generator, set the DIP switch as follows.

We recommend a regular inspection (to establish the current condition of the system), and maintenance if required (to return the
system to its original condition).

2 Electric emergency/booster heater
ff
Reset the high limit safety cut-out by pressing the reset
button.
ff
Check whether the heating water is being circulated at a sufficiently high flow rate.
16.3 Fan noise
The heat pump draws heat from the outdoor air. This causes the
outdoor air to cool down. At outside temperatures of 0 °C to 8 °C,
the air may be cooled to below freezing point. If under these
conditions precipitation occurs in the form of rain or fog, ice may
form on the air grille, the fan blades or the airways. If the fan
comes into contact with this ice, this creates noise.
Note
Keep the air discharge and intake apertures free from
snow and ice.
17.1 Clean condensate pan and drain
WARNING Risk of electrocution!
Before removing the casing parts, disconnect all poles
of the appliance from the power supply.
Environmental influences can lead to the condensate pan and
drain becoming contaminated or blocked. To clean, proceed as
follows:
ff
Remove the casing parts (see chapter “Fitting casing parts”).
ff
When installed indoors, also carefully remove the foil from
the appliance frame.
D0000035004
How to remedy rhythmic scratching or grinding noises:
ff
Check whether the condensate drain is clear of obstructions.
ff
Check whether the design output and temperature are set
correctly. Ice formation is particularly pronounced when
a high heating output is called for at moderate outside
temperatures.
ff
Carry out a manual defrost, as many times as necessary,
until the fan runs freely again. Observe the information in the
heat pump manager instructions and the “START DEFROST”
parameter in the “COMMISSIONING / COMPRESSOR” menu.
ff
At outside temperatures above +1 °C, shut down the appliance or switch it over to emergency mode for approx. 1 hour.
After this, the ice should have melted.
ff
Check that the appliance is installed in line with installation
conditions.
ff
If the noises occur frequently, notify customer support.
Regularly remove all leaves and accumulated dirt from the evaporator fins, which can be accessed by removing the side panel on
the condenser side.
D0000035036
D0000033633
If heat meters are installed, their sieves should be cleaned regularly.
ff
Remove the lower cover panel.
