Appliance description
3.1.2 Cooling
The appliance is an air | water heat pump that operates as a heating heat pump. The appliance extracts heat
from the outdoor air at a low temperature level and transfers it to the heating water at a higher temperature level.
The heating water can be heated up to a flow temperature of 60 °C.
The appliance is equipped with an electric emergency/booster
heater (DHC). To safeguard heating operation and the provision
of high DHW temperatures, the electric emergency/booster heater is activated as an emergency heater if the dual mode point
is undershot in mono mode operation. If the same happens in
mono energetic operation, the electric emergency/booster heater
is activated as a booster heater.
Additional features
-- Suitable for underfloor and radiator heating systems
-- Preferred for low temperature heating systems
-- Still extracts heat from the outdoor air at –20 °C outside
temperature
-- Corrosion-protected, external casing made from hot-dipped
galvanised sheet steel plus stove-enamelled finish
-- Comprises all components and safety equipment required for
operation
-- Filled with non-combustible safety refrigerant
3.1
Function
3.1.1 Heating
Heat is extracted from the outdoor air via the heat exchanger
(evaporator) on the air side. The evaporated refrigerant is compressed by a compressor. This process requires electrical energy. At this point, the refrigerant is at a higher temperature level.
A further heat exchanger (condenser) transfers the heat to the
heating circuit. 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 process collects in
the defrost pan and is drained off via a hose.
!
Material losses
During 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 chapter "Menu / Menu
description / SETTINGS / HEATING / STANDARD SETTING /
BUFFER OPERATION" in the WPM installation instructions.
This prevents damage to the heat pump as a result of
unfavourable conditions.
The heat pump automatically reverts to heating mode at the end
of the defrost cycle.
!
Material losses
In dual mode operation, return water from the second
heat generator may flow through the heat pump. Please
note that the return temperature must be no higher than
60 °C.
www.stiebel-eltron.com
!
Material losses
The heat pump is not suitable for continuous, year-round
cooling.
ff
Observe the application limits (see chapter "Specification / Data table").
!
Material losses
In cooling mode, condensate can form when the dew
point temperature is undershot.
ff
Take suitable measures to prevent the formation of
condensate.
Rooms are cooled by reversing the heat pump circuit. Heat is
extracted from the heating water. The evaporator transfers this
heat to the outdoor air.
Area cooling and fan cooling require the installation of the FET
remote control unit in a reference room to capture the relative humidity and the room temperature as part of dew point monitoring.
With fan cooling, it is also necessary to install a buffer cylinder.
Heat pump application limit
The heat pump is switched off if the outside temperature falls
below the selected lower application limit for cooling (LIMIT COOLING parameter).
4.
Settings
The system is operated exclusively via the WPM heat pump manager.
ff
Observe the heat pump manager operating and commissioning instructions.
5.
Maintenance and care
!
Material losses
Maintenance work, such as checking the electrical safety,
must only be carried out by a qualified contractor.
!
Material losses
ff
Keep the air discharge and intake apertures free
from snow and leaves.
A damp cloth is sufficient for cleaning all plastic and sheet metal
parts. Never use abrasive or corrosive cleaning agents.
ff
Protect the appliance from dust and dirt during building
work.
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".
We recommend a 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).

7.1
General safety instructions
We guarantee trouble-free function and operational reliability only
if original accessories and spare parts intended for the appliance
are used.
7.2
Instructions, standards and regulations
Note
Observe all applicable national and regional regulations
and instructions.
The tested appliance conforms to IEC 61000-3-12.
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 make special arrangements for a supply
air vent in the installation room, to prevent any further increase in
the negative pressure in this 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
At +8 °C condenser temperature, the integral frost protection circuit automatically starts the heating circulation pump in the heat
pump circuit, thereby ensuring circulation in all water carrying
sections.

10.1 Transport
If possible, transport the appliance to the installation site on the
non-returnable pallet. Alternatively, transport the appliance using
a sack truck, creeper board or tension belt, which can be positioned around the left-hand adjustable feet as a carrying strap.
ff
When transporting the appliance, be aware of its centre of
gravity.
ff
Protect the appliance against heavy impact during transport.
-- If the appliance needs to be tilted during transport, this
must only be for a short time and onto the r.h. side panel.
Ensure that the John Guest connectors point upwards during
transport.
-- The longer the appliance is tilted, the greater the distribution
of refrigerant oil inside the system.
ff
Wait approximately 30 minutes before starting the appliance
after it has been tilted.
ff
If possible, transport the appliance in its packaging.
!
Material losses
If the appliance is transported without packing and without using a pallet, its outer casing may be damaged.
To prevent this, remove the side and front panels (see
chapter "Fitting the appliance casing").
Note
You may need to remove the front panel to manoeuvre
the appliance through a door (see chapter "Fitting the
appliance casing").
Material losses
A buffer cylinder with diffusion-proof insulation is essential to enable cooling by means of fan convectors. The
emergency/booster heater must be connected.
Note
When providing cooling via an underfloor heating system
no buffer cylinder is required.
766
766
We recommend the use of a buffer cylinder to ensure trouble-free
appliance operation.
Note
For operation without a buffer cylinder, we recommend
installing an electric emergency/booster heater (DHC).

www.stiebel-eltron.com
Material losses
To ensure the push-fit connector is held securely, pipes
with a surface hardness > 225 HV (e.g. stainless steel)
must have a groove.
ff
Using a pipe cutter, cut a groove (depth approx. 0.1 mm) at a defined distance from the end of
the pipe.
-- Pipe diameter 22 mm: 17±0.5 mm
-- Pipe diameter 28 mm: 27.5±0.5 mm
How the push-fit connectors work
The push-fit connectors are equipped with a retainer with stainless steel serrations and an O-ring for sealing. The push-fit connectors also have a "twist and secure" function. Simply turning
the screw cap by hand will secure the pipe in the connector and
push the O-ring against the pipe to seal it.

Material losses
Do not use open vented heating systems. Use oxygen
diffusion-proof pipes in underfloor heating systems with
plastic pipework.
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
In the case of oxygenation, separate the heating system between the heating circuit and the buffer cylinder.
Undoing the push-fit connection
If the push-fit connectors later need to be undone, proceed as
follows:
ff
Turn the screw cap anti-clockwise until there is a narrow gap
of approx. 2 mm. Press the retainer back with your fingers
and hold on to it.
ff
Pull out the inserted pipe.
Material losses
The heating system to which the heat pump is connected
must be installed by a qualified contractor in accordance
with the water installation drawings that are part of the
technical guide.
!
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.

On its l.h. side the appliance is equipped with the "Outlet condensate drain" connection.
ff
Connect a condensate line to the "Outlet condensate drain"
connection.
!
Note
ff
Never add inhibitors or other additives (e.g. glycol)
to the fill water.
Material losses
To ensure the condensate drains off correctly, never kink
the condensate line. If necessary, create a loop.
ff
Route the condensate line with a sufficient fall.
Note
If conductivity is >1000 μS/cm, desalination treatment is
recommended as the best option for preventing corrosion.
ff
Route the condensate into a drain near the floor. When doing
so, ensure the drain is adequately ventilated, e.g. free discharge into a trap. Use a condensate pump if there is insufficient fall.
ff
Check the position of the condensate pump. The condensate
pump must fully rest on the floor.
Pressure relief valve drain
Material losses
To avoid damage as a result of scaling, it may be necessary to soften or desalinate the fill water. The fill water
limits specified in chapter "Specification / Data table"
must always be observed.
ff
Recheck these limits 8-12 weeks after commissioning and as part of the annual system maintenance.
Note
Suitable appliances for water softening and desalinating,
as well as for filling and flushing heating systems, can be
obtained from trade suppliers.
Filling the heating system
On the l.h. side of the appliance, the "Safety valve drain" connection routes the pressure relief valve discharge hose out of the
casing. Ensure that draining water can run off freely.
!
Material losses
Never switch on the power before filling the system.
10.9 Checking the condensate drain
!
Material losses
High flow rates or water hammer can damage the appliance.
ff
Fill the appliance at a low flow rate.
After routing the condensate drain hose, check that the condensate
can drain off correctly. For this, proceed as follows:
ff
Pour water onto the evaporator, which will then flow into the
defrost pan. Observe the maximum condensate drain capacity of 6 l/min.
ff
Check whether the water is draining off through the condensate drain hose.
10.10 Temperature controller 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 temperature controller to limit the system temperature.
www.stiebel-eltron.com
In the delivered condition, the diverter valve of the MFG is positioned at the centre. This ensures the heating and DHW circuits are
filled equally. When the power is switched on, the diverter valve
automatically moves into the heating position.
If you intend to fill or drain the system later, first return the diverter
valve to its centre position.
For this, enable controller parameter DRAIN HYD in the menu
DIAGNOSIS / RELAY TEST SYSTEM.
ff
Fill the heating system via the drain.
ff
After filling the heating system, check the connections for
tightness (visual and physical inspection).

Effect of the electric emergency/booster
heater
If the dual mode point is undershot, the electric emergency/booster heater safeguards both the heating operation and the provision of high DHW temperatures.
Emergency mode
If the heat pump shuts down due to a fault, the heating
output is covered by the electric emergency/booster
heater.
Heat-up program
Where return temperatures are <25 °C, the electric
(only for underfloor emergency/booster heater must provide the necessary
heating systems)
heat for screed drying.
With such low system temperatures, the heat for screed
drying must not be provided by the heat pump, otherwise the frost protection of the appliance can no longer
be guaranteed during the defrost cycle.
When the heat-up program has ended, the electric
emergency/booster heater can be disconnected if it is
not required for appliance operation.
Please note that during the heat-up program, emergency mode is not available.
Pasteurisation mode The electric emergency/booster heater starts automatically when pasteurisation mode is active. The DHW is
then regularly heated to 60 °C to protect it against the
growth of legionella bacteria.

!
Material losses
Observe the maximum system temperature for underfloor
heating systems.
ff
Check that the heating system is filled to the correct pressure
and the air vent valve has been closed.
ff
Check whether the outside temperature sensor and the return sensor are correctly placed and connected.
ff
Check whether additional sensors are correctly positioned
and connected.
ff
Check whether the power supply is connected correctly.
D0000071617
ff
Observe the quick-fit adaptor installation instructions.
ff
If the air hose is too long for the installation situation, you
may need to trim it. Cut to size using a sharp knife. The wire
spirals can be cut using wire cutters.
ff
Reset the temperature controller by pressing the reset
button.
14.2 Commissioning the heat pump manager
Commission the heat pump manager and make all settings in accordance with the heat pump manager operating and installation
instructions.
14.3 Initial start-up
14.3.1 Heating curve adjustment
The efficiency of a heat pump decreases as the flow temperature
rises. Adjust the heating curve carefully. Heating curves that are
set too high result in the zone or thermostatic valves closing, which
may result in the minimum required flow rate in the heating circuit
being undershot.
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 a remote control.
-- At different outside temperatures (e.g. -10 °C and +10 °C),
adjust the heating curve so that the required temperature is
achieved in the lead room.
Standard values to begin with:
14.1.1 High limit safety cut-out
Parameters
At ambient temperatures below -15 °C it is possible that the temperature controller of the electric emergency/booster heater may
trip.
ff
Check whether the temperature controller has tripped.
ff
Remove the cause of the fault if necessary.
ff
Remove the side panel (see chapter “Fitting the appliance
casing”).

select "SETTINGS / HEATING / HEATING CIRCUIT" and raise the
"COMFORT TEMPERATURE" parameter.
Note
If no remote control is installed, raising the "COMFORT
TEMPERATURE" parameter will lead to a parallel offset
of the heating curve.
If the room temperature is too low when outside temperatures are
also low, increase the "HEATING CURVE" parameter.

Installation
Appliance shutdown
If the "HEATING CURVE" parameter has been raised and outside
temperatures relatively high, adjust the zone valve or thermostatic
valve in the lead room to the required temperature.
!
Material losses
Never reduce the temperature in the entire building by
closing all zone valves or thermostatic valves, instead do
this by using the setback programs.
Once everything has been implemented correctly, the system can
be heated to its maximum operating temperature and vented once
again.
!
Material losses
For underfloor heating systems, observe the maximum
permissible system temperature for that particular underfloor heating.
14.3.2 Other settings
ff
For operation with or without a buffer cylinder, see chapter
“Menu / SETTINGS / HEATING / STANDARD SETTING / BUFFER OPERATION” in the WPM commissioning instructions.

ff
Then set the "LOWER APP LIMIT HZG" parameter to 30 °C.
WARNING Electrocution
ff
Before working on the appliance, isolate it from the
power supply at the terminal area.
Following disconnection from the power supply, parts of
the appliance may remain energised for 2 minutes until
the inverter capacitors have discharged.
Note
After completing the heat-up process, reset the "DUAL
MODE TEMP HZG" and "LOWER APP LIMIT HZG" parameters to their respective standard values or to the respective system values.
Note
Please observe the heat pump manager operating and
installation instructions.
15. Appliance shutdown
!
Material losses
Never interrupt the heat pump power supply, even outside of the heating season. Otherwise, system frost protection is not guaranteed.
The heat pump manager automatically switches the heat
pump to summer or winter mode.
15.1 Standby mode
To shut the system down, simply set the heat pump manager to
"Standby mode". This way, the safety functions that protect the
system remain enabled, e.g. frost protection.

accumulated dirt if necessary (see chapter "Cleaning the condensate pan").
18.1 Cleaning the evaporator fins
Check the evaporator fins for dirt from time to time.
17.3 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 air routing pipes. If the
fan comes into contact with this ice, this creates noise.

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 demanded 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.
