Application area
The heat pump module may only be used in closed heating systems in
accordance with EN 12828.
Other usage is prohibited. Any damage resulting from prohibited usage
is excluded from liability.
Heating system minimum volume and operation
To avoid multiple start/stop cycles, incomplete
defrosting or unnecessary alarms, a sufficient amount of
energy stored in the system is required. Energy is stored
in the heating system water volume, as well as in the
system components (radiators) and in the concrete
foundation (underfloor heating system).
Since the requirements vary for different heat pump installations and
heating systems, no general minimum volume is stated. Please refer to
the following prerequisites for all heat pump sizes instead:
Under floor heating system without a buffer cylinder
To ensure that a sufficient amount of energy is available for defrosting,
the largest room should not contain room thermostats but room
controllers should be used instead. At least 30 m2 floor surface should
be regulated by a room controller, since the heat pump then will adjust
flow temperature automatically.
Radiator system without a buffer cylinder
To ensure that a sufficient amount of energy is available for defrosting,
there should be at least 4 water radiators of 500 W/unit in one system
without mixing valve. A room controller is recommended, since the heat
pump then will automatically adjust flow temperature.
Radiator and under floor heating systems on different circuits
without a buffer cylinder
To ensure that a sufficient amount of energy is available for defrosting,
there should be at least 4 water radiators of 500 W/unit in the circuit
without mixing valve. No minimum floor surface is required for the
AirModule 6 720 813 268(2014/10)
General
underfloor heating system circuit with mixing valve. A room controller is
recommended, since the heat pump then will automatically adjust flow
temperature.
Only circuits with mixing valve
To ensure that a sufficient amount of energy is available for defrosting, a
buffer cylinder of at least 50L is required for heat pump sizes 5-9 and of
at least 100L for heat pump sizes 13-17.
Fan convector
To ensure that a sufficient amount of energy is available for defrosting, a
buffer cylinder of at least 10L is required.
3.4
Type plate
The data plate is found on the module roof plate.
3.5
Transport and storage
The heat pump module must always be transported and stored upright.
If needed, it may be leaned temporarily.
The heat pump module may not be stored or transported in
temperatures below – 10 °C.
3.6
Heat pump module positioning
• The heat pump module is placed indoors. Pipework between the heat
pump and the heat pump module should be as short as possible. The
pipes must be insulated ( Chapter 7.16).
• Leakage drain water from the pressure relief valve should be drained
from the heat pump module to a frost protected outlet.
• The space where the heat pump module is placed must have a floor
drain.
3.7
Checks before installation
▶ Check that all pipe connections are intact and have not shaken loose
during transportation.
▶ Before operation of the heat pump module, the heating system and
the water heater, including the heat pump module, must be filled and
depressurized.
▶ Wiring should be kept as short as possible to protect the system from
downtime, for example during a thunderstorm.
▶ Low voltage wiring must be separated from high voltage wiring by at
least 100 mm.
3.8
Connection principle
The principle is based on floating condensation and a immersion heater
in the heat pump module. The user interface manages the heat pump
and the heat pump module according to a set heating curve.
When the heat pump is not able to heat the house on its own, the heat
pump module automatically starts the booster heater and produces
together with the heat pump the desired temperature in the house.
DHW is prioritized and is managed by a sensor TW1 in the hot water
cylinder. While the heater is heated, the heating system heating mode is
temporarily disconnected by a 3-way valve. When the hot water cylinder
is heated, the heat pump heating mode continues.
Heating and DHW mode when heat pump is inactive:
At outside temperatures below app. –20 °C (adjustable value) the heat
pump stops automatically and cannot produce hot water. The booster
heater in the heat pump module will in this case take over both the
heating mode and the DHW production. The heat pump will restart when
the temperature gets above –17 °C.

System configurations
The heat pump and heat pump module may be installed
only in accordance with the official system solutions
provided by the manufacturer.
Other system solutions are not allowed. Any damage and
problems resulting from prohibited installation are
excluded from liability.
4.2.1
Circulation pump PC1 is controlled by the control unit in the heat pump
module.
If a fresh water station is installed, it must have its own control unit.
If a buffer cylinder is used, a 3-way valve VC0 must be installed in
accordance with the system solution. The 3-way valve replaces the Tunit in the safety assembly ( Chapter 5.1.1) and is connected
electrically to terminal VC0 on the installer module.

Heating circuit
Non-return valve
One non-return valve in each heating circuit is required for preventing
natural circulation in the heating system in summer mode. Natural
circulation may arise as the domestic hot water 3-way valve is open to
the heating system when the heat pump prepares DHW heating.

7.5
Water quality
7.6
Heat pumps operate with lower temperatures than other heating
systems, which means that the thermal degassing is not as effective and
the oxygen content will never be as low as in an electric/oil/gas system.
This means that the heating system will be more sensitive to rust with
aggressive water.
NOTICE: System damage due to objects in the pipes!
Objects in the pipes will decrease the flow and cause
operational problems.
▶ Flush out the system to remove all dirt residues
before connecting the heat pump and heat pump
module.
Do not use any water additives except for pH-enhancer and keep the
water clean.
Recommended pH level is 7.5 – 9.

1) Electric anode (accessory) in the water heater is recommended for higher
chloride content. If electric anode is used, it has to be purchased in
connection with commissioning.
Heating system flushing
The heat pump module is a part of a heating system. Problems in the heat
pump module can be caused by poor water quality in the radiators/floor
loops or by constant system oxygenation.
Oxygen causes corrosion products in the form of magnetite and
sediment.
Magnetite has a grinding effect on the heating system's pumps, valves
and components with turbulent flows such as the condenser.
Heating systems which require regular filling or where the heating water
does not produce clear water during water sampling require measures
prior to the installation of the heat pump, e.g. supplementing the heating
system with magnetite filters and air vent valves.
7.7
Operation without heat pump (stand-alone)
The heat pump module can be put into operation without a connected
heat pump, for example, if the heat pump is installed at a later date. This
is called "stand-alone" operation.
In stand-alone mode, the heat pump module uses only the integrated
immersion heater for heating and DHW production.
If the heat pump module and the heating system are
filled before the heat pump is connected, then the heat
transfer medium in and out to / from the heat pump must
be connected to secure circulation ( [1] and [2],
Fig. 13).
▶ Open shut-off valves on the heat transfer circuit, if
applicable.
In connection with commissioning of stand-alone operation:
▶ Set Stand-alone mode in the service menu Heat pump ( Chapter
12.1).
7.8
Installation with cooling
Cooling is disabled in the UK model to comply with
the regulations for RHI.
Using cooling mode requires the installation of a room
controller (accessory).
Installation of a room controller with integrated humidity
sensor (accessory) makes cooling mode more secure as
the user interface automatically adjusts the flow
temperature in relation to the current dew point.
▶ Insulate all connections and pipes from condensation.
▶ Install a room controller, with or without an integrated moisture
sensor ( manual for the respective room controller).
▶ Install condensation sensors ( Chapter 7.18).
▶ Select automatic mode heating/cooling ( Chapter 12.3.2,)
▶ Make the necessary cooling mode settings: start temperature, start
delay, room temperature and dew point differential (offset), as well
as lowest flow ( Chapter 12.3.2).
▶ Set the temperature differential (delta) over the heat pump (
Chapter 12.1.1)

NOTICE: Risk of malfunction!
Cooling mode is not possible if the mixing valve for the
pool is placed in a wrong position in the system. Even
other functional disturbances might arise. The mixing
valve for the pool must not be positioned so that it can
block the safety valve on the flow line.
▶ Install the mixing valve for pool on the return pipe to
the heat pump module ( [VC1] Bild 12).

NOTICE: The installation will get damaged if the power is
connected without water.
Components in the heating system can overheat if the
power is connected before it has been filled up with
water.
▶ Fill and pressurize the water heater and the heating
system before connecting the installation to power.
The heat pump and the heat pump module are connected by a
communications wire, CAN-BUS.
A suitable cable for external cable installation is wire LIYCY (TP)
2x2x0.75, or equivalent. An alternative cable should have a cross
section area of at least 0.75 mm2, and be a duplex cable, screened and
approved for outside use. The screen should only be grounded in one
end (indoor unit) and to the chassis.
Maximum cable length is 30 m.
The connection between the circuit boards is by four wires, because the
12V-supply between the circuit boards must also be connected. The
circuit boards have markings for both the 12V and CAN-BUS
connections.
Switch Term is used to mark the start and end of a CAN-BUS loop.
Ensure that the correct circuit board is terminated and that all other
switches are in the opposite position.
The heat pump module electrical connection must be
disconnected safely in accordance with the wiring rules.
▶ Install a separate safety switch that disconnects all
power to the heat pump module. In case of separate
power supplies you will need one safety switch for
each supply.
The compressor warms up before it starts. This can take
up to 2 hours, depending on the outside temperature.
The requirement is that the compressor temperature
(TR1) is 10 K above the air intake temperature (TL2).
The temperatures are visible in the Diagnostics menu (
Chapter 12.9).
For recommended fuse sizes, see Technical information
(Chapter 4.1).
▶ Choose cable area and type that represent the fuse protection and
wire mode.
▶ Connect the heat pump according to the circuit diagram. Never
connect any other consumers.
▶ If the heat pump is connected through a circuit breaker, then a
separate circuit breaker for the heat pump must be used. Please
observe current regulations.
▶ Observe the colour coding when replacing circuit boards.
8.1
CAN-BUS
NOTICE: Malfunction due to electrical disturbances!
High voltage lines (230/400 V) close to a
communications line can cause the heat pump module
to malfunction.
▶ Install screened CAN-BUS wire away from a power
cord. Minimum distance 100 mm. Cabling together
with bus lines is allowed.
NOTICE: The system will be damaged if the 12 V- and
the CAN-BUS connections are confused!
The communication circuits are not designed for 12 V
constant voltage.
▶ Check that the four cables are connected to plugs
with corresponding rating on the printed circuit
board.

EMS-BUS
NOTICE: Malfunction due to electrical disturbances!
High voltage lines (230/400 V) close to a
communications line can cause the heat pump module
to malfunction.
▶ Install the EMS-BUS wire away from a power cord.
Minimum distance 100 mm. Cabling together with
bus lines is allowed.
EMS-BUS and CAN-BUS are not compatible.
▶ Do not connect EMS-BUS units with CAN-BUS units.
The user interface HPC400 and the installer module in the heat pump
module are connected by EMS-BUS.
The user interface is powered via the BUS cable. Polarity is not important
for the two cables in the EMS-BUS.
In case of EMS-BUS accessories it is important to note that (please also
refer to the installation instructions for each accessory):
▶ If several BUS units are installed, they must be separated by at least
100 mm.
▶ If several BUS units are installed, they must be connected in a series
or a star network.
▶ Use a cable with a cross section area of at least 0.5 mm2.
▶ In case of external inductive interferences (e.g. from PV systems),
use screened cables. The screen should only be grounded in one end
and to the chassis.

Printed circuit board handling
8.4.1
External outputs
Circuit boards with control electronics are sensitive to discharges of
static electricity (ESD – ElectroStatic Discharge) when handled. To
prevent damaging the components, special care is therefore required
when handled.
NOTICE: Damage due to incorrect connection!
Connections intended for a different voltage or current
can damage electrical components.
CAUTION: Damage due to static electricity!
▶ Wear a grounded antistatic wrist strap when
handling unenclosed printed circuit boards.
▶ Only add connections to the heat pump module
external outputs that are compatible with 5 V and 1
mA.
▶ If an intermediate relay is required, use only relays
with gold-plated plugs.
External inputs I1, I2, I3 and I4 can be used to remotely manage certain
functions in the user interface.
The functions that are activated by the external inputs are described in
chapter 12.1.2.
The external input is connected either to a power switch for manual
activation or to operating equipment with a relay output for 5 V.
8.5
6 720 614 366-24.1I
Fig. 20 Antistatic wrist strap
Damage is usually latent, and a circuit board can operate correctly
during commissioning but show signs of problems later. Charged
objects may only be problematic if they are in close proximity to the
electronics. Keep a distance of at least one metre from expanded
polystyrene, protective plastic and other packaging, synthetic material
(e.g. fleeces) and similar before starting work.
A method for good ESD protection is a ground-connected bracelet when
handling electronics. This bracelet must be put on before opening the
screened metal bag/packaging or before exposing an installed board.
The bracelet must be worn until the circuit board is enclosed in its screen
packaging or closed electric box. Replaced, returned circuit boards must
be handled in the same way.
8.4
Accessories
CAN-BUS connected accessories, e.g. power guard, are connected to
the installer card in the heat pump module parallel on the CAN-BUS
connection to the heat pump. They can also be connected in series with
other CAN-BUS connected units.
8.6
Connecting the heat pump module
▶ Remove the front panel.
▶ Remove the electric box cover.
▶ Feed the connecting cables through the cable feed in the ceiling and
to the electric box. Use an extension spring, if required.
▶ Feed the cables so that the electric box can be tilted forward.
▶ Connect the cables according to the circuit diagram.
▶ Put the electric box cover and the heat pump module front panel
back.
External connections
To avoid inductive interference, all low voltage conductors (measure
current) should be installed with a minimum distance of at least 100 mm
from the conducting 230V- and 400V cables.
If the temperature sensor conductor has to be extended, the following
conductor diameters should be used:
• Up to 20 m long cable: 0.75 to 1,50 mm2
• Up to 30 m long cable: 1.0 to 1,50 mm2
The relay output PK2 is active during cooling and can be used to manage
the exchange between cooling /heating of a fan convector or a
circulation pump or to regulate floor heating circuits in moist rooms.
Output VC0 is active during cooling and is used to manage a 3-way valve
to recirculation, to facilitate the exchange between DHW heating and
cooling.

Product description
• The user interface will manage a heating system with max. four
heating/cooling circuits, DHW heating with solar energy and heating
from solar power.
• In heat pump mode, optimized operation without time program will
provide the lowest energy consumption.
• The user interface can also operate according to a time program:
– Heating: 2 time programs for each heating circuit with two break
points per day. Heat circuits 2 to 4 can only change to heating
mode when heating circuit 1 is in heating mode if there is no
buffer cylinder installed.
– DHW: a time program for DHW heating.
• The user interface shows information from the heat pump module
and the heating system. It is also used to modify settings.
• After 1½ hour of operation the user interface has a battery life of at
least 8 hours. If a power outage lasts longer than the battery life, the
time and date settings will be erased. All other settings are saved.
• The functional scope and thus the menu structure of the user
interface are determined by the structure of the system. Reference to
the importance of the system structure to the functions will be made
in relevant places. Setting ranges and standard settings may not
correspond with the information in these instructions.
• Room controller CR10H as a separate room controller, which
measures relative humidity (for heating/cooling circuits)
• MM100: Module for heating and cooling circuits with mixing valve
• MP100: Module for heat pump heated pool
• MS100: Module for solar energy DHW heating
• MS200: Module for extended solar thermal systems
Instructions validity for modules supporting EMS plus
These instructions also apply to the user interface in combination with
heating/cooling circuit module MM100 (accessories).
Additional setting options may be found in some menus, if your heating
system is equipped with other modules (e.g. solar module, accessories).
These setting options are described in the module technical information.
9.1.1 Control modes
The following main control modes are available for heating:
• Outside temperature compensated control: automatic flow
temperature control based on outside temperature.
• Outside temperature compensated control influenced by room
temperature: automatic flow temperature control based on outside
temperature and room temperature. A room controller must be
installed in the reference room.
If the cooling mode is active, it will be set to an adjustable constant
temperature.
Further information on control modes and settings that influence control
( chapter 12.3, page 44).
9.2
Important notices on usage
WARNING: Risk of scalding!
If thermal disinfection has been activated to avoid
legionella, the hot water is heated once to in excess of
65 °C. The factory setting for the hot water temperature is
60 °C. There is a risk of scalding at the draw-off points if
the temperature is set higher than this.
▶ Make sure that a mixing device that prevents scalding
is installed. If in doubt, ask your contractor.
NOTICE: Floor damage!
▶ If using underfloor heating, ensure that the floor type
max. temperature is not exceeded.
▶ Optionally, install an extra temperature switch, and
connect it to one of the external inputs.
• Only products from the same distributor may be used within the EMS
BUS system.

11.3.1 Checklist: adjust settings according to customer
requirements
When commissioning a device, ensure the satisfaction of both parties,
making sure that the heating system meets the customer's needs and will
not give cause for complaints. In our experience, the following settings
are very important for the satisfaction of the system user:

program according to the customer's
requirements ( User interface operating
instructions).
Table 22 Checklist: important settings identify customer requirements
▶ Adjust other settings in the main menu according to the customer's
requirements ( Operating instructions).
11.3.2 Important system settings
If relative humidity is not measured in a cooled room
(e.g. with a CR10H), condensation might form. In this
case, it is required to set the minimum flow temperature
to a suitable value to prevent condensation.
The service menu settings must under all circumstances be checked and
if necessary modified during commissioning. Otherwise the system
function cannot be ensured. It is best to check all displayed settings. It is
possible that the set values must be verified by the system user, e.g. the
cooling settings.
11.4
Performing the function test
The function test is located in the Diagnostics menu. The available items
depend on the installed system. In this menu, you can test e.g. the: DHW
circulation pump: On/Off ( Chapter 12.9.1, page 54).
11.5
Check monitored values
Monitored values are shown in the Diagnosis menu ( Chapter 12.9.2,
page 54).
11.6
System handover
▶ Ensure that there are no temperature restrictions for heating and
DHW set on the heat pump module. Otherwise the user interface
cannot control the DHW or flow temperature.
▶ Explain to the customer how the user interface and the accessories
work and how to operate them.
▶ Inform the customer about the selected settings.

Sunshine will to a certain extent influence outside temperature compensated control (the solar thermal
energy decreases the required heat output).
The control does not take sunshine into consideration.
The outside temperature compensated control will operate independently from the room temperature.
Room temperature deviation equivalent to the setting is adjusted by a parallel offset of the heating curve
(only if a room controller is installed in a suitable reference room). The higher the setting value, the greater
is the max. room temperature influence on the heating curve.

Outside temperature compensated (optimised heating curve)
The heating curve provides an economic and convenient operation of
the heating system with outside temperature compensated control. The

point is 25 °C flow temperature. The heating curve end point must be set
according to the heating system´s system temperature.
This calculation takes into account the adjusted outside temperature
and the room control temperature. The room control temperature
consists of the desired room temperature (set room temperature value)
and the room influence.
Decisive to the course of the heating curve (slope/gradient) are the two
parameters minimum outside temperature ( page 44) and system
temperature (the flow temperature that should be reached at minimum
outside temperature) ( fig. 40 and 41, left).
This way, the user can influence the heating curve directly by changing
the room temperature set value.
The most important settings are: system temperature, maximum flow
temperature, room temperature offset (parallel offset) and minimum
outside temperature.
The heating curve ( fig. 40 and 41) is in principle determined by the
curve base and end points. At an outside temperature of 20 °C the base

Constant heating below a certain outside temperature
SS-EN 12831 (Heating systems in buildings - Method for calculation of
the design heat load) shows how heating surfaces and heat sources are
dimensioned for a certain output to maintain a comfortable heating. In
setback mode, the heating system can be cooled down more than what
is required for this.
With the Heat constantly below parameter it is possible to set an
outside temperature threshold value at which the temperature setback
mode is shut off (applies to adjusted outside temperature). This allows
smaller heating surfaces to be utilised.

▶ Fill to 2 bar unless stated otherwise.
▶ If there is a pressure drop: check the expansion vessel and heating
system for leaks.
16.2
Pressure switch and overheating protection
The pressure switch and the overheating protection are connected in
serial, so that a tripped alarm or information in the user interface means
either that the system pressure is too low, or that the immersion heater
temperature is too high.
NOTICE: Risk of damage due to dry run!
The heat transfer pump PC0 can get damaged if it
operates for a longer period of time with insufficient
pressure in the system.
▶ Repair any leaks in the system if the pressure switch
is tripped.
Tripped pressure switch only blocks the immersion
heater. The circulation pump PC0 and the heat pump can
continue to operate in case of risk of freezing.
Pressure switch
The heat pump module is equipped with a pressure switch, which is
tripped when the heating system pressure is below 0.5 bar. The
pressure switch will reset itself when the pressure is above 0.5 bar.
▶ Check that the expansion vessel and the pressure relief valve have
the required pressure for the installation.
▶ Check for leaks in the system.
▶ Slowly increase the heating system pressure by adding water
through the fill valve.
Overheating protection
The overheating protection is tripped if the immersion heater
temperature is above 95 °C.
▶ Check the system pressure.
▶ Check the heating and DHW settings.
▶ Reset the overheating protection by pressing the button at the
bottom of the electric box ( [3], fig. 22).
16.3
Operating temperatures
The operating temperature check must be performed in
heating mode (not in DHW or cooling mode).
For optimal operation of the installation it is important that the heat
pump and heating system flow is checked. This check should be
performed after 10 minutes heat pump operating time and during high
compressor heating output.
The temperature differential over the heat pump should be set for
different heating systems ( Chapter 12.1.1),
▶ For underfloor heating system; set the heating temp. diff. to 5 K.
▶ For radiators; set the heating temp. diff. to 8 K.
These settings are optimal for the heat pump.
Check the temperature differential during high compressor heating
output:
▶ Go to the Diagnostics menu.
▶ Select Monitored values.
▶ Select Heat pump.
▶ Select Temperatures.
Table 42 Operating pressure

AirModule 6 720 813 268(2014/10)
Environmental protection
▶ Check Primary flow temperature. (heat transfer medium out sensor
TC3) and Return temperature (heat transfer medium in sensor TC0)
in heating mode. The flow should have a higher temperature than the
return.
▶ Calculate the differential by TC3 – TC0.
▶ Check that the differential corresponds with the set heat transfer
fluid delta.
If the temperature differential is too large:
▶ vent the heating system.
▶ Clean the filters / strainers.
▶ check pipe dimensions.

name and address of the target server are stored in the standard
settings of the module. As soon as an internet connection is
established, the module automatically logs on to the server.
• Local network
The module does not have to be connected to the internet. It can also
be used in a local network. In this case, however, the module cannot
be reached via the internet, and the IP-module software cannot
automatically update.
• The app IVT Anywhere
When the app is opened for the first time, the predefined login name
and password must be entered. The login information can be found
on the IP-module data plate.
NOTICE: You will lose your login information when you
change IP-module!
Each IP-module has its own unique login information.
