6 720 810 350-01.1I

3.2 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.

3.3 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 m 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

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.
General

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.

7.5 Water quality

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.
Do not use any water additives except for pH-enhancer and keep the water clean.
Recommended pH level is 7.5 – 9.
Water quality
Hardness < 3°dH Oxygen content < 1 mg/L Carbon dioxide, Co Chloride ions, Cl- < 250 mg/L Sulphate, So42- < 100 mg/L Conductivity < 350 μs/cm
Table 10 Water quality
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.

7.6 Heating system flushing

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.
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)

▶ Turn off floor circuits in moist rooms (e.g. bathrooms and kitchens)
and use relay outputs PK2 in order to govern this ( Chapter 8.4).

7.9 Installation with solar heater (only solar model)

Using solar additional heating requires installation of a solar module (accessory).
The solar energy coil in the cylinder is intended for maximum added heating output of 4.5 kW. Only DHW heating is possible with the integrated coil.
▶ Install solar panels ( panel manual). ▶ Insulate all connections and pipes. ▶ Install solar module ( solar module manual). ▶ Select Yes to the question Solar thermal sys installed during
commissioning ( Chapter 11.2).
▶ Make the necessary settings for the installed solar thermal system
( Chapter 12.6)

7.10 Installation with pool

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).
▶ Install the T-pipe on the flow line from the heat pump
module, before the bypass in the safety assembly.
▶ The pool mixing valve may not be installed as a
heating circuit.
Installation of a pool module (accessory) is demanded to use pool heating.

Electric installation

8 Electric installation

DANGER: Risk of electric shock!
The heat pump module components conduct electricity.
▶ Turn off the main power before any electrical work.
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 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).
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 mm
2
, 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.
6 720 809 156-24.1I
Fig. 19 Termination CAN-BUS

8.2 EMS-BUS

▶ 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.
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 mm
2
.
▶ 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.

8.3 Printed circuit board handling

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.
CAUTION: Damage due to static electricity! ▶ Wear a grounded antistatic wrist strap when
handling unenclosed printed circuit boards.
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.
8.4.1 External outputs
NOTICE: Damage due to incorrect connection!
Connections intended for a different voltage or current can damage electrical components.
▶ 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 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.

8.4 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 mm
• Up to 30 m long cable: 1.0 to 1,50 mm
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.
Relay output max. load: 2A, cos>0.4. Higher load requires installation of an intermediate relay.

User interface

9 User interface

9.1 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.
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).
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.

9.2 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.

If some functions are not activated, and modules, units or components are not installed, the non relevant items are hidden, while other settings are selected.
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:
Menu Item Customer requirements/settings
Control type Outside temp. compensated ( page 47) Adjusting the heating curve Adjust the heating curve ( page 47). The
displayed heating curve applies to a room
temperature of 21 °C. Building type (adjustment) Light, Medium, Heavy ( page 45) Operating mode Adjust the standard settings/own time
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.

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.

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).
▶ System commissioning as described in Chapter 11. ▶ Vent the system as described in Chapter 14. ▶ Test active system components as described in Chapter 12.9.1. ▶ Check that the heat pump commissioning requirements have been
fulfilled.
▶ Check that there is a heating or a DHW demand.
-or­▶ Create a demand either by running the hot water or by raising the
heating curve (if the outside temperature is high, you can optionally
also modify the setting for Heating mode from). ▶ Check that the heat pump starts. ▶ Check that there are no Current alarms according to Chapter 12.9.3.
-or­▶ Solve operating errors according to Chapter 13. ▶ Check operating temperatures according to Chapter 16.3.

Indication on pressure gauge
1 bar Minimum system pressure (when cold)
2.5 bar Maximum filling pressure at max. temperature of the heating water: may not be exceeded (safety valve
opens).
Table 42 Operating pressure

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.

AirModule 6 720 813 268(2014/10)
▶ 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.

Fig. 50 Electric box

Check the heating system particle filters (in the safety assembly)

The filters will prevent dirt from entering the system. Operating problems might occur if these are blocked.
It is not necessary to empty the installation in order to clean the filters. Filter and shut-off valve are integrated.
Cleaning the strainer
▶ Close the valve (1). ▶ Screw off the hood (by hand), (2). ▶ Take out the strainer and clean it by running water over it or by
pressure cleaning.
▶ Put the strainer back; it has rails that fit into the groove in the valve to
avoid incorrect installation (3).

Function check

▶ Perform function checks ( Chapter 16).

Electric cabling

▶ During service, the electric box may be tilted forward for easier
access. ▶ Check the cable for mechanical damage. Replace damaged cables.
