3. Information on the heat pump
Application area
The split air/water heat pump for heating water temperatures up to 55 °C and air
temperatures down to -15 °C or -20 °C is designed exclusively for the heating of heating
water and domestic hot water. The heat pump can be used in new or existing heating
systems, taking into consideration the application limits (see "Specification").
Operating principle of a heat pump The heat pump converts the low-temperature heat contained in the outdoor air into
high-temperature heat. To achieve this, air is drawn in by the fan and routed over the
evaporator (1).
The evaporator contains liquid heat transfer medium. This boils and evaporates at low
temperatures and low pressures. The required evaporation heat is extracted from the
air, which cools down in the process. The air is then released back into the atmosphere.
The evaporated heat transfer medium is drawn in by compressor (2) and compressed
to a higher pressure. The compressed, gaseous heat transfer medium is pushed into
the condenser (3), where it condenses at high pressure and high temperature. The
condensation heat is transferred to the heating water, causing the water temperature
to rise.
The energy transferred to the heating water corresponds to the energy that was
previously extracted from the outdoor air, plus the small amount of electrical energy
required for compression.
The pressure in the condenser and upstream of the expansion valve (4) is high. Via
the expansion valve, a temperature-sensitive pressure reduction occurs, causing the
pressure and temperature to drop. The cycle then starts again.

Please note
3064298_201507
The heat pump is automatically protected against frost when it is switched on. The
use of anti-freeze is not permissible.
Risk of water damage and faulty operation through freezing.
By choosing a heat pump heating system, you are helping to protect the environment
through low emissions and efficient use of primary energy. To ensure that your new
heating system operates at maximum efficiency, please bear in mind the following points:
The heat pump heating system must be carefully sized and installed. Avoid
unnecessarily high flow temperatures. The lower the flow temperature on the
heating water side, the more efficiently the heat pump operates. Ensure that the
controller is adjusted correctly.
Intermittent ventilation is preferable. Compared to airing with the windows
permanently tilted open, this method of ventilation reduces energy consumption
and saves you money.

3. Information on the heat pump
Other equipment features
The appliance is equipped with sensors that monitor the heating circuit and the refrigerant
circuit.
DHW cylinders
Wolf heat pumps require special DHW cylinders for heating the domestic hot water;
these are available from the Wolf range of accessories.
The indirect coil surface area in the DHW cylinders must be at least 0.25 m² per kW
of heating output.
Please note
Water treatment
Please note
VDI 2035 Part 1 lists recommendations for the prevention of scaling in heating
systems. Part 2 deals with corrosion on the water side.
When screed drying using the heater rod, particular care should be taken to ensure
that the permissible total hardness is complied with, otherwise there is a risk of
scaling and heater rod failure.
The permissible water hardness is 16.8°dH for system volumes of up to 250 litres
during operation with the electric heating rod.
Permissible hardness in °dH
We also recommend a heating water pH value of between 6.5 and 9.0 for mixed
installations comprising various materials.
In the case of high-volume systems or those where large top-up water volumes
(e.g. due to water losses) are required, the following values should be observed.
250 l

System volume in l
If the limit curve is exceeded, an appropriate portion of the system water must be
treated.
Example: Total hardness of the domestic hot water: 16 °dH
System volume: 500 l
i.e. at least 250 l must be treated.
Water hardness
The adjustable cylinder water temperature can exceed 60 °C. Short-term operation
at temperatures above 60 °C must be monitored in order to prevent scalding. For
permanent operation, appropriate precautions should be taken to prevent draw-off
temperatures above 60 °C, e.g. thermostatic valve.
To protect against scaling, the DHW temperature must be set to max. 50 °C when
the total water hardness is 15 °dH (2.5 mol/m³) or above. If the total hardness is
16.8 °dH or above, we recommend using a water treatment facility in the cold water
supply line when heating DHW, in order to prolong the maintenance interval. Even if
water hardness is less than 16.8 °dH, an increased risk of scaling may occur in some
areas, necessitating suitable softening measures. Failure to take such measures will
result in premature scaling of the appliance and reduced DHW convenience. The
contractor should always check the local conditions.
Corrosion protection
Do not use (for cleaning, polishing, etc.) or store sprays, solvents, chlorinated
cleaning agents, paints, lacquers, adhesives, salts, etc. on or in the vicinity of the
heat pump.
Under unfavourable conditions, these materials may cause corrosion in the heat
pump and other heating system components.
Only clean the casing with a damp cloth and a mild chlorine-free detergent. To finish,
dry off immediately.

Split air/water heat pump for
outdoor installation
Installation information:
When selecting the installation site, observe the following points:
- The heat pump must be accessible on all sides. The air intake should preferably be
on a wall.
- The air discharge side must be free from obstruction. Since the air being
discharged is around 8 K below than the ambient temperature, premature ice
formation should be expected. Therefore do not discharge the air directly onto
walls, patios or footpaths. There should be at least 3 m clearance between the heat
pump discharge and walls, patios, footpaths, etc.
- To prevent air short circuits and sound reflection, avoid installing in recesses or
between two walls.
- Installation in a depression is not permitted as the cold air will sink and no air
exchange will take place.
- To avoid causing disturbance, bear in mind the sound levels and distance from
neighbouring properties when selecting a site.
- Bear in mind the prevailing wind direction / prevent air short circuits
- The condensate should drain away into the gravel bed.
- Protect air intake/discharge from leaves and snow.
- Provide thermal insulation for underground pipes.
Do not site the air source heat pump for outdoor installation in an environment that is
polluted with corrosive gases, such as acids, or alkaline gases.
Do not install in a location directly exposed to onshore winds, as this will result in a
risk of corrosion from the saline air, particularly on the evaporator fins. In locations
with strong winds it may be necessary to construct wind protection to divert the
onshore wind.
Strong winds may interfere with evaporator ventilation.
In areas with high snowfall or in very cold places, protective measures must be taken
to ensure that the heat pump operates correctly. Incorporate the outdoor unit into the
lightning protection system.
Do not install the heat pump with the discharge side facing the prevailing wind
direction.
When siting the heat pump in occupied / communal areas, as opposed to a separate
plant room, the minimum room volume in relation to the refrigerant charge weight
must be complied with. In accordance with EN 378-1, the following limit applies to
R410A refrigerant: 0.44 kg/m³ refrigerant per cubic metre room volume.
For refrigerant lines less than 12 m, the refrigerant charge weight provided is
sufficient. For refrigerant lines between 12 m and a maximum of 25 m long, an
additional 0.06 kg/m of R 410A needs to be added; consequently, a larger room
volume is required for the indoor module (see table).

Transport to the installation site
To prevent damage during transport, the heat pump must remain packaged and on its
wooden pallet while being transported to the final installation site by pallet truck.
Only transport the heat pump by pallet truck while packaged.
Caution, risk of tipping.
To prevent damage to the appliance, the heat pump's outdoor module
must not be tilted more than 45° during transport.
The components, in particular the plastic casings and the pipework for
the refrigerant circuit and heating side, must not be used to transport
the appliance. Only use the grab handles provided when transporting
the heat pump.
Bear in mind the weight of the heat pump.

18. Filling the refrigerant lines
Please note:
Certificate of competence
The handling of refrigerant and work on the refrigerant circuit must be carried
out by a refrigeration engineer or other suitably qualified person, such as a
heating contractor with a certificate of competence (to para 5, section 3 of the
ChemKlimaschutzV [or local regulations] in conjunction with (EC) Regulation
No. 303/2008 Category I). Applicable standards and regulations and recognised
engineering standards must be observed.
Suitable personal protective equipment must be used when handling refrigerant.
Refrigerant R410A used in WOLF split heat pumps is an air-displacing, non-toxic
gas. Uncontrolled release of refrigerant may result in breathing difficulties and
asphyxiation. Observe the corresponding regulations and guidelines for handling this
refrigerant.
Ensure adequate ventilation in enclosed spaces. Observe the regulations and
guidelines for handling R 410A.
Direct contact with refrigerant can be harmful to skin. Wear protective goggles and
gloves.
Please note
When adding refrigerant or drawing it off from the system, the water carrying
side of the plate heat exchanger in the indoor unit must be flushed with water
or drained completely. Otherwise, the plate heat exchanger may be damaged.
The installed refrigerant lines and all necessary connectors must have suitable
thermal insulation.

18. Filling the refrigerant lines
Filling the indoor module and
refrigerant lines
Single refrigerant line length < 12 m
The pre-filled quantity of refrigerant in the outdoor module is sufficient for a single line
length of 3 to 12 m.
Single refrigerant line length > 12 m
Line lengths of 12 - 25 m must be topped up with an additional 60 g/m of refrigerant
R410A.
The additional refrigerant can be added after evacuating the refrigerant lines and
before opening the shut-off valves on the outdoor module.

19. Testing the refrigerant lines for leaks
Checking the refrigerant
circuit for leaks
R 410A is an air-displacing, non-toxic gas. Uncontrolled release of refrigerant may
result in breathing difficulties and asphyxiation.
Check the connections for refrigerant leaks:
- All flared connections on the refrigerant lines between the indoor and outdoor unit.
- All soldered joints and screw connections on the refrigerant lines in the indoor and
outdoor unit.

Connection for the
vent hose
Return, heating / DHW 28 x 1
Flow, heating 28 x 1
Hose, safety valve DN 25
Flow, DHW 28 x 1
Vent
An air vent valve must be installed at the highest point on the system.
Flushing the heating system
The following points must be observed for the heating side:
- To prevent any existing dirt in the heating system from causing malfunctions in the
heat pump, the heating system must be thoroughly cleaned and flushed before the
heat pump is connected. This applies to new systems and in particular when replacing
an appliance.
- The flow and return on the heat pump side must be equipped with shut-off systems
and 2 BDF valves so that the condenser can be flushed when required.
Filling the heating system
Before commissioning, the system must be filled and vented.
- Open the cap on the vent in the indoor module by one revolution.
- Open all heating circuits.
- Slowly fill the entire heating system and boiler while cold via the BDF valve at the
return, up to approx. 2 bar pressure (observe pressure gauge).
- Check the entire system for water leaks.
- Slowly open the expansion vessel.
- Switch on the heat pump.
- Vent the heating circuits completely: Use the contractor level, and under "Relay
test" select the desired pump. Then switch the pump ON for 5 seconds and OFF for
5 seconds, five times in succession.
- When the system pressure drops below 1.5 bar, top up the water.
30
3064298_201507
20. Connecting the heating / cooling
circuit and the DHW circuit
Draining the heating system
- Switch off the system (see operating instructions) and allow to cool to at least
40 °C, otherwise there is a risk of scalding
- Safeguard the heating system against accidental reconnection of the power supply
- Open the drain valve (boiler drain & fill valve), for example on the indoor module
- Open the air vent valves on the heating circuits
- Drain off the heating water
Overflow valve
If no separating cylinder is being used, the minimum heating water flow rate can be
ensured by means of an overflow valve.
DHW heating
Do not operate via the buffer cylinder
Circulation pump
An electronically regulated high-efficiency pump is integrated into the indoor module
Hydraulic separating
cylinder (low loss header)
Used when there are several heating circuits
Maximum thermostat (MaxTh)
To protect surface heating systems (e.g. underfloor heating circuits) from excessively
high flow temperatures, temperature limiters or maximum thermostats are required.
The floating contacts of maximum thermostats and, where applicable, dew point monitors,
can be connected in series and connected to the programmable input E1.
When the contact opens, the heat source is switched off.
The following parameters
are critical for the transfer of
the heat pump output to the
heating system:
.
- The heating water flow rate (m ) in m3/h (nominal flow rate)
- The temperature differential between the flow and return (∆t)
- The specific heat content of the water (c)
.
.
QWP = m x c x ∆t (kW)
Pipe dimensions
- The pipe dimensions must be matched to the nominal flow rate.
- Ensure that the system is vented correctly.
- Flush the system.
Dirt trap
To protect the heat pump, a dirt trap must be installed in the heating return.
Installing dirt traps or carrying out any other modifications in the supply line to
the safety valve is not permitted.
Wolf recommends a sludge separator with magnetite separator to protect the
appliance and the high-efficiency pump from dirt / sludge and magnetite.
Dew point monitor (TPW)
A dew point monitor (accessories) is required for surface cooling systems (e.g. underfloor
heating circuit, cooling ceiling). If the cooling circuit serves several rooms with different
relative humidities, several dew point monitors must be installed and connected in series.
The monitors are fitted to the cooling circuit flow in the room to be cooled. Remove the
insulation from this area.
If required, the dew point monitor can be installed directly on the indoor unit. In this
case, the switching point must be reduced slightly, e.g. 90 % rel. humidity instead of
95 % rel. humidity.
3064298_201507
31
20. Connecting the heating / cooling
circuit and the DHW circuit
DHW cylinders
- The DHW cylinder must be equipped with an internal indirect coil suitable for the
heating output of the heat pump.
- The internal indirect coil should have a surface area of at least 0.25m² per kW of
heating output.
- The pipework must be sufficiently large (> DN 25).
Buffer cylinder
Since variable flow rates can arise on the heat draw-off side depending on the load,
the minimum flow rate must be ensured to enable fault-free heat pump operation.
This is usually achieved by installing a separating buffer cylinder or a low loss header.
A buffer cylinder is essential for all systems with radiators, individual room
temperature control (thermostatic valves), multiple heat generators or heating
circuits.
For air/water heat pumps with output-dependent control in connection with 100 %
underfloor heating, there is no need to use a buffer cylinder, provided the following
condition is met:
1 (or more) lines of the heating system (e.g. bathroom) is permanently and fully open
(requires the written consent of the operator). For this, the minimum flow rate must be
verified by means of a pressure drop calculation.
If necessary, one (or more) heated heating circuits(s) can be specifically opened fully
via output A1 during defrost mode.
The valve opening time must be < 20 sec.

In order to ensure that the heat pump operates reliably and efficiently, it is essential
that the flow rates specified in the technical data for the heating circuit can be
guaranteed. The following table lists the required minimum cross-sections for the
pipework on the heating circuit side. On systems with a separating cylinder or low
loss header, these cross-sections must, as a minimum, be observed up to the
separating cylinder (e.g. incl. the BSP/BSH) or the low loss header.

General information
General information,
electrical connection
The installation may only be carried out by an approved electrical
contractor. Observe VDE regulations and all local regulations of your
power supply utility company.
An omnipolar isolator with at least 3 mm contact separation must be
integrated in the power cable upstream of the appliance.
The use of a type B AC/DC-sensitive RCD is recommended, as only
this type is suitable for DC residual currents.
Type A RCDs are not suitable.
Do not route sensor leads alongside 230 V or 400 V cables.
Danger due to live electrical components.
Please note: Turn off the ON/OFF switch before removing the casing.
Never touch electrical components or contacts when the ON/OFF
switch is in the ON position. This carries a risk of electrocution that
could result in injury or death.
The terminals are live even when the ON/OFF switch is in the OFF
position.
During servicing and installation work, isolate the entire system
from the power supply at all poles, otherwise there will be a risk of
electrocution.
Before connecting the appliance to the power supply, ensure that all
electrical covers and protective devices are fully installed.

The sensor calibration function serves to balance out any deviations in the
measurements from the flow and return temperature sensors (T_boiler and T_return).
The temperature sensors are calibrated at the factory; sensor calibration is required
after replacing a sensor or carrying out a parameter reset.
Procedure:
Activation of the feed/heating circuit pump ZHP and correction of the flow temperature
sensor value (T_boiler) to the value of the return temperature sensor by setting
"FL correction".
For calibration, switch on ZHP, wait 10 minutes for the temperature to equalise, then
perform correction if necessary.

Measuring location outside the residence affected but close by (0.5 m in front of the open window that is most affected)
When siting the system, the following must be observed:
Avoid siting the heat pump directly by or below windows of noise-sensitive rooms, e.g. bedrooms.
Installation in recesses or between 2 walls is not recommended, as this will increase the noise level due to sound reflection.
The sound power level of heat pumps is calculated in accordance with DIN EN 12102. It enables comparisons to be made
independently of surroundings, direction and distance.
Installation up to 3 m from a wall (Q=4):

33. Configuring the dual mode point
Configuration example
Central heating demand (building heat load) to DIN 4701 or EN 12831 of 7.7 kW. A DHW demand for 4 people (0.25 kW/person)
and a standard outside temperature of -16 °C are assumed.
The power supply utility specifies a blocking time of 2 x 2 hours. The blocking time factor Z is 1.1.
Using these figures, the required heat pump output is calculated as follows:
.
.
.
QHP = (QB + QDHW) x Z
.
.
.
QE-rod = QHP - QHP,Tn

=
(7.7 kW + 1.0 kW) x 1.1 = 9.6 kW
=
9.6 kW - 5.6 kW = 4.0 kW

As can be seen from the diagram, the theoretical heating output for the standard design point is approx. 5.6 kW. Since a 4 kW
heater rod is also installed, the maximum available heating output is 9.6 kW at an outside temperature of -16 °C.
This results in a dual mode point of approx. -4 °C.
The closer the dual mode point gets to the standard outside temperature, the lower the proportion of booster heating.
As a rule, the booster heater is responsible for approx. 30 - 60 % of the required heating output. Though the proportion of output
attributable to the booster heater is relatively large, the proportion of work is only approx. 2 - 5 % of the annual heating load.
In the example shown, a DHW cylinder with a water capacity of 300 litres can meet the daily requirements of a 4-person
household (detached house, high demand of 4 x 70 litres/day = 400 l DHW cylinder).
No changes would be made to the selected heat pump type in this example.

52. Commissioning
Commissioning
To ensure correct operation, we recommend that the system is commissioned by
our customer service department.
A commissioning report with checklist is supplied with every appliance and should
be worked through before commissioning.
The key criteria are:
- Has the appliance been positioned and installed in line with the installation instructions?
- Have all electrical and hydraulic connections been completed in full?
- Are all slides and shut-off valves in the heating water circuit open?
- Have all circuits been flushed and thoroughly vented?
- Is condensate drainage guaranteed?
- Do the power feeds to the compressor, electric heating and control system have
omnipolar fuse protection?
- Before commissioning, it is essential to carry out an function test on the circulation

53.1 Responsibilities of the
operator
As part of the Kyoto Protocol, the European Union is committed to reducing the
emissions of fluorinated greenhouse gases. To this end, EC Regulation 517/2014
of 16/04/2014 has been adopted. The overriding goal of this F Gas Regulation is to
reduce F gas emissions over the entire life cycle of these gases.
In accordance with regulation (EC) no. 517/2014, the owner/operator has the
following obligations:
53.1.1
Annual leak test
Refrigerant weight in
delivered condition
Refrigerant per m of pipe
In accordance with Article 4, systems which contain more than 3 kg of refrigerant
and which are not hermetically sealed or, as of 2017, systems with a CO2 equivalent
mass of 5 t or more, must undergo an annual leak test. For systems containing
less than 3 kg of refrigerant, but with a CO2 equivalent mass of more than 5 t, a
transitional period applies until 31/12/2016. From 01/01/2017, these systems will then
be required to undergo an annual leak test.
Wolf split heat pumps use F-gas R410A, an HFC mixture with a global warming
potential (GWP100) of 2088. This means that 1 kg of R410A equates to 2.088 t of
CO2.
Which Wolf split heat pumps require a leak test is detailed in the following table.
BWL-1S(B)-07
BWL-1S(B)-10
BWL-1S(B)-14
2.15 kg (4.49 t CO2 eq)
2.95 kg (6.16 t CO2 eq)
2.95 kg (6.16 t CO2 eq)
60 g R410A/m pipe length corresponds to 125 kg CO2 eq /m pipe length
From 2015 to end 2016 No (refrigerant weight of less than
3 kg)
From 2017
No (less than 5 t CO2 eq)
No (refrigerant weight of
less than 3 kg)
No (refrigerant weight
of less than 3 kg)
Yes, if pipe length has
been extended
Yes, if pipe length has
been extended
Yes (more than 5 t CO2 eq) Yes (more than 5 t CO2 eq)
Yes, if pipe length has been
extended by more than 4 m (total
length greater than 16 m)
-
-
Conversion to charge weight CO2 equivalent mass:
Refrigerant weight x GWP100 = Charge weight as CO2 equivalent mass
Example: 2.15 kg R410A * 2088 kg CO2 = 4489 kg CO2 = 4.49 t CO2
The leak test may only be carried out by certified contractors/refrigeration engineers in accordance with
EC 842/2006, 303/2008 and 517/2014.
Important:
This regulation also applies to systems which were sold/installed before 01/01/2015.

53. System log book
53.1.2
Compulsory documentation
All work carried out on a heat pump, e.g. maintenance, repair and leak tests, must be
documented and the record of results must be retained for five years.
This obligation applies to the operator and the company carrying out the work.
The following data must be entered:
ff Details of all repair and maintenance work
ff Type of refrigerant filled into the system (new, re-used or recycled) and the
quantity of refrigerant removed from the system
ff If an analysis of a re-used refrigerant is available, the results must also be
documented in the system report.
ff The origin of the re-used refrigerant
ff System modifications and replaced components
ff Results of all regular routine tests
ff Prolonged shutdowns
53.1.3
Dismantling of heat pump and
disposal of refrigerant
104
The heat pump must only be dismantled and the refrigerant contained in it must only
be disposed of by certified contractors/refrigeration engineers in accordance with
EC 842/2006, 303/2008 and 517/2014.

54. Maintenance / cleaning
Cleaning the evaporator on
the BWL-1S(B)
Please note
In areas with high concentrations of dust or pollen, shorter cleaning intervals
may be necessary alongside the mandatory annual inspection and cleaning, in
order to ensure that the system operates efficiently. Adjust the cleaning interval
to suit the local conditions.
The evaporator must be checked annually for dirt/contamination and cleaned if
necessary. Wet cleaning with a commercially available garden hose is recommended.
Contaminated fins may reduce the system's transfer performance and consequently its
energy efficiency, and in the worst case scenario may result in system failure.
When cleaning, ideally use a wide nozzle with a spray angle of 15° -20°. To prevent
damage to the fins, direct the water spray at the evaporator surface from the front at an
angle of 90°. When cleaning, the water pressure should not exceed 2 - 3 bar.
Please note
Cleaning the condensate pan /
condensate drain
Never spray the fins from the side, as this may cause them to become deformed
or bent. Maintain a distance of approx. 20 cm to 30 cm from the evaporator
surface.
Before the heating season, remove any dirt (leaves, twigs, sludge, etc.) from the
condensate drain.
Before opening the appliance, ensure that all power circuits are isolated from
the power supply.
When cleaning, avoid using sharp or hard objects in order to prevent damage to the
evaporator and condensate pan.
In extreme weather conditions (e.g. drifting snow), ice may occasionally form on the
intake and discharge grilles. In this event, remove any ice and snow from the intake
and discharge areas to ensure the minimum flow rate.
Regularly check and clean the condensate pan to ensure correct drainage. Check
and clean the condensate drain hose. For correct drainage, ensure that there is a
continuous fall.
Cleaning the casing
The appliance can be cleaned with a damp cloth and commercially available detergents.
Never use abrasive cleaners or detergents containing acid or chlorine on the appliance
surfaces.
Cleaning the dirt trap / sludge
separator
Install a sludge separator in the heating return. This ensures that neither particles nor
dirt can get into the plate heat exchanger (condenser) of the heat pump. Condenser
blockages and any resulting high-pressure malfunctions are thereby prevented.

55. Troubleshooting
General information
Never remove, bypass or otherwise disable any safety or monitoring equipment. Only operate the heat pump in perfect technical
condition. Any faults or damage which impact or might impact upon safety must be remedied immediately by a qualified
contractor. Only replace faulty components and equipment with original Wolf spare parts.
Faults are shown in plain text on the display of the control accessory – AM display module or BM-2 programming unit – and
correspond to the messages listed in the following tables.
A fault symbol on the display (symbol: triangle with exclamation mark) indicates an active fault message. A lock symbol (symbol:
lock) indicates that the current fault message has caused a lockout of the heat pump. The duration of the current message is
also shown.
Please note

Faults must only be repaired by
qualified personnel. If a fault message is
acknowledged several times without the
cause of the problem being repaired, this can
lead to component or system damage.
The control unit automatically acknowledges
faults such as faulty temperature sensors or
other sensors if the part concerned has been
replaced and plausible test values have been
supplied.
