1.4 Energy-Efficient Use of the Heat Pump

1.1 Symbols and markings

Particularly important information in these instructions is marked with CAUTION! and NOTE.

CAUTION!

Immediate danger to life or danger of severe personal injury or significant damage to property.

NOTE

Risk of damage to property or minor personal injury or important information with no further risk of personal injury or damage to property.

1.2 Intended Use

This device is only intended for use as specified by the manufacturer. Any other use beyond that intended by the manufacturer is prohibited. This requires the user to abide by the relevant project planning documents. Please refrain from tampering with or altering the device.

1.3 Legal Regulations and Directives

This heat pump is designed for use in a domestic environment according to Article 1, Paragraph 2 k) of EU directive 2006/42/ EC (machinery directive) and is thus subject to the requirements of EU directive 2014/35/EU (low-voltage directive). It is thus also intended for use by non-professionals for heating shops, offices and other similar working environments, in agricultural establishments and in hotels, guest houses and similar / other residential buildings.

This heat pump conforms to all relevant DIN/VDE regulations and EU directives. Refer to the EC Declaration of Conformity in the appendix for details.

The heat pump must be connected to the power supply in compliance with all relevant VDE, EN and IEC standards. Any further connection requirements stipulated by local utility companies must also be observed.

The heat pump is to be connected to the heat source system and the heating system in accordance with all applicable regulations.

This unit can be used by children aged 8 and over and by persons with limited physical, sensory or mental aptitude or lack of experience and/or knowledge, providing they are supervised or have been instructed in the safe use of the unit and understand the associated potential dangers.

Children must not play with the device. Cleaning and user maintenance must not be carried out by children without supervision.

CAUTION!

When operating or maintaining a heat pump, the legal requirements of the country where the heat pump is operated apply. Depending on the refrigerant quantity, the heat pump must be inspected for leaks at regular intervals by a certified technician, and these inspections must be recorded.

More information can be found in the accompanying log book.

By operating this heat pump you are helping to protect our environment. Both the heating system and the heat source must be properly designed and dimensioned to ensure efficient operation. It is particularly important to keep water flow temperatures as low as possible. All connected energy consumers should therefore be suitable for low flow temperatures. Raising the heating water temperature by 1K corresponds to an increase in energy consumption of approx.

2.5%. Low-temperature heating systems with flow temperatures between 30^ and 50^ are particularly well-suited for energy-efficient operation.

2 Purpose of the Heat Pump

2.1 Application

The water-to-water heat pump is to be used exclusively for the heating of heating water. It can be used in newly built or previously existing heating systems. Water is used as the heat carrier. It can be supplied by wells or other water systems.

In order to eliminate the risk of corrosion at the evaporator, the well water must be evaluated regarding the corrosion behaviour of metallic materials according to DIN 50930.

Details can be found in the project planning and installation manual for heat pumps for heating purposes.

CAUTION!

The well water must comply with the required water quality standards. (see Cap. 9.4 on pag. 9)

2.2 Operating Principle

A well pump conveys the water to the evaporator of the heat pump. There the heat is transferred to the refrigerant in the refrigerating circuit.

The refrigerant is drawn in by the electrically driven compressor, compressed and "pumped" to a higher temperature level. The electrical power needed to run the compressor is not lost in this process. Most of it is absorbed by the refrigerant as well.

Subsequently, the refrigerant is passed through the condenser where it transfers its heat energy to the heating water.

Depending on the set operating point (thermostat setting), the heating water is thus heated up to a max. of 62^ .

3 B a s i c D e v i 4Acessories

The basic device consists of a ready-to-use heat pump for indoor installation, complete with casing, switch box and integrated Heat pump manager. The refrigeration circuit is "hermetically sealed" and contains the fluorinated refrigerant R410A included in the Kyoto protocol. Information on the GWP value and CO_2 equivalent of the refrigerant can be found in the chapter Device information. The refrigerant is CFC-free, non-ozone depleting and non-combustible.

All components required for the operation of the heat pump are located in the switch box. An external wall temperature sensor including fixing accessories and a dirt trap are supplied with the heat pump. The supply for the load current and the control voltage must be installed at the building site.

The supply lead of the well pump (to be provided by the customer) must be connected to the switch box. It is important to ensure that the integrated motor protection is sufficient for the pump provided by the customer.

1) Liquifier
2) Control panel
3) Evaporator
4) Compressor
5) Filter dryer
6)Economizer
7) Expansion valve

4.1 Remote control

A remote control adds convenience and is available as a special accessory. Operation and menu navigation are identical to those of the heat pump manager. Connection takes place via an interface (special accessories) with RJ 12 Western plug.

NOTE

In the case of heating controllers with a removable operating element, this can also be used directly as a remote control.

4.2 Building management technology

The heat pump manager can be connected to a building management system network via supplementation of the relevant interface plug-in card. The supplementary installation instructions of the interface card must be consulted regarding the exact connection and parameterisation of the interface.

The following network connections can be made on the heat pump manager:

Modbus
EIB, KNX
Ethernet

CAUTION!

If the heat pump or circulating pumps are controlled externally, an flow rate switch is required to prevent the compressor from being switched on when there is no volume flow.

5 T r a n s p o r t 6 S e t - u p

A lift truck is suited for transporting the unit on a level surface. Carrying straps may be used if the heat pump needs to be transported on an uneven surface or carried up or down stairs. These straps can be passed directly underneath the pallet.

CAUTION!

The heat pump is not fixed to the pallet.

CAUTION!

The heat pump must not be tilted more than 45^ direction).

Use the holes provided in the sides of the frame to lift the unit without the pallet. The side panel assemblies must be removed for this purpose. Any commercially available length of pipe can be used as a carrying aid.

CAUTION!

Do not use the holes in the panel assemblies for lifting the device!

After the transport, the transport securing device is to be removed.

CAUTION!

The transport securing device is to be removed prior to commissioning.

6.1 General Information

The compact water-to-water heat pump must be installed in a frost-free, dry room on an even, smooth and horizontal surface. The entire base of the frame should lie directly on the floor to ensure an adequate soundproof seal. If supporting feet are used, the heat pump must be installed horizontally. In this case, the specified sound level can be up to

3 dB(A) higher, and additional sound insulation measures may be necessary.

The heat pump must be installed so that maintenance work can be carried out without hindrance. This can be ensured by maintaining a clearance of approx. 1 m in front of and on each side of the heat pump.

Neither frost nor temperatures higher than 35^ must occur in the installation location at any time of the year.

6.2 Acoustic Emissions

The heat pump operates silently due to efficient sound insulation. Internal insulation measures should be carried out to prevent vibrations from being transmitted to the foundation or to the heating system.

7 Installation

7.1 General Information

The following connections need to be established on the heat pump:

Flow and return flow of the well system
Flow and return flow of the heating system
Temperature sensor
Voltage supply

7.2 Heating System Connection

CAUTION!

Flush the heating system prior to connecting the heat pump.

Before connecting the heating water system to the heat pump, the heating system must be flushed to remove any impurities, residue from sealants, etc. Any accumulation of deposits in the liquifier could cause the heat pump to completely break down.

Once the heating system has been installed, it must be filled, de-aerated and pressure-tested.

Consideration must be given to the following when filling the system:

Untreated filling water and make-up water must be of drinking water quality (colourless, clear, free from sediments)
Filling water and make-up water must be pre-filtered (pore size max. 5 m

Scale formation in domestic hot water heating systems cannot be avoided, but in systems with flow temperatures below 60^ , the problem can be disregarded. With high-temperature heat pumps and in particular with bivalent systems in the higher performance range (heat pump + boiler combination), flow temperatures of 60^ and more can be achieved. The following standard values should therefore be adhered to with regard to the filling and make-up water according to VDI 2035, sheet 1: The total hardness values can be found in the table.

Fig. 7.1:Guideline values for filling and make-up water in accordance with VDI 2035

Total heat output in kW	Total alkaline earths in mol/m3and/or mmol/l	Specific system volume (VDI 2035) in l/kW
		< 20	≥ 20 < 50	≥ 50
		Total hardness in °dH
< 50	≤ 2.0	≤ 16.8	≤ 11.2	< 0.111
50 - 200 < 2.0		< 11.2 < 8.4
200 - 600 ≤ 1.5		≤ 8.4	< 0.111
> 600 < 0.02		< 0.111

1. This value lies outside the permissible value for heat exchangers in heat pumps.

For systems with an above-average specific system volume of 50 l/kW, VDI 2035 recommends using fully demineralized water and a pH stabiliser to minimize the risk of corrosion in the heat pump and the heating system.

CAUTION!

With fully demineralized water, it is important to ensure that the minimum permissible pH value of 7.5 (minimum permissible value for copper) is complied with. Failure to comply with this value can result in the heat pump being destroyed.

Minimum heating water flow rate

The minimum heating water flow rate through the heat pump must be assured in all operating states of the heating system. This can be accomplished, for example, by installing either a dual differential pressureless manifold or an overflow valve. The procedure for adjusting an overflow valve is described in the Chapter Start-Up.

□NOTE

The use of an overflow valve is only recommended for panel heating and a max. heating water flow of 1.3m^3 /h System faults may result if this is not observed.

The antifreeze function of the heat pump manager is active whenever the heat pump manager and the heat circulating pumps are ready for operation. If the heat pump is taken out of service or in the event of a power failure, the system has to be drained. The heating circuit should be operated with a suitable antifreeze if heat pump systems are implemented in buildings where a power failure can not be detected (holiday home).

7.3 Heat Source Connection

The following procedure must be observed when connecting the heat source:

Connect the well pipes to the heat pump's flow and return.

A

CAUTION!

The well water must comply with the required water quality standards. (see Cap. 9.4 on pag. 9)

The hydraulic integration diagram must be adhered to.

7.4 Temperature sensor

The following temperature sensors are already installed or must be installed additionally:

External temperature sensor (R1) supplied (NTC-2)
Return temperature heating circuit (R2) installed (NTC-10)
Return temperature primary circuit (R24) installed (NTC-10)
Flow temperature heating circuit (R9) installed (NTC-10)
Flow temperature primary circuit (R6) installed (NTC-10)

The temperature sensors to be connected to the heat pump manager must correspond to the sensor characteristic curve illustrated in Fig.7.2 on pag. 6. The only exception is the external temperature sensor included in the scope of supply of the heat pump (see Fig.7.3 on pag. 6)

Fig. 7.2: Sensor characteristic curve NTC 10
Fig. 7.3: Sensor characteristic curve, NTC-2 according to DIN 44574 External temperature sensor

7.4.2 Mounting the external temperature sensor

The temperature sensor must be mounted in such a way that all weather conditions are taken into consideration and the measured value is not falsified.

• Mount on the external wall on the north or north-west side where possible
• Do not install in a "sheltered position" (e.g. in a wall niche or under a balcony)
  Not in the vicinity of windows, doors, exhaust air vents, external lighting or heat pumps
  Not to be exposed to direct sunlight at any time of year

7.4.3 Installing the strap-on sensor

It is only necessary to mount the strap-on sensors if they are included in the scope of supply of the heat pump but have not yet been installed.

The strap-on sensors can be fitted as pipe-mounted sensors or installed in the immersion sleeve of the compact manifold.

Mounting as a pipe-mounted sensor

Remove paint, rust and scale from heating pipe.
- Coat the cleaned surface with heat transfer compound (apply sparingly).
- Attach the sensor with a hose clip (tighten firmly, as loose sensors can cause malfunctions) and thermally insulate.

7.4.4 Hydraulic distribution system

The compact manifold and the dual differential pressureless manifold function as an interface between the heat pump, the heating distribution system, the buffer tank and, in some cases, even the hot water cylinder. A compact system is used to simplify the installation process, so that a lot of different components do not have to be installed individually. Further information can be found in the relevant installation instructions.

Compact manifold

The return sensor can remain in the heat pump, or should be installed in the immersion sleeve. The remaining empty space between the sensor and the immersion sleeve must be filled completely with heat transfer compound.

Dual differential pressureless manifold

In order for the heating circuit pumps of the generator and consumer circuits to supply the flow to the return sensor, this must be installed in the immersion sleeve of the dual differential pressureless manifold.

7.5 Electrical connection

7.5.1 General

All electrical connection work may only be carried out by a trained electrician or a person qualified for the tasks in hand in accordance with the

installation and operating instructions,
country-specific installation requirements (e.g. VDE 0100)
- technical connection requirements of the energy suppliers and supply grid operators (e.g. TAB) and
the local conditions.

To ensure that the frost protection function of the heat pump works properly, the heat pump manager must remain connected to the power supply and the flow must be maintained through the heat pump at all times.

The switching contacts of the output relay are interference-suppressed. Therefore, depending on the internal resistance of the measuring instrument, a voltage can also be measured when the contacts are open. However, this will be much lower than the line voltage.

Extra-low voltage is connected to controller terminals N1-J1 to N1-J11; N1-J19; N1-J20; N1-J23 to N1-J26 and the terminal strips X3; X5.1. If, due to a wiring error, the line voltage is mistakenly connected to these terminals, the heat pump manager will be destroyed

7.5.2 Electrical installation

1) The supply cable (with up to 5 cores) for the power element of the heat pump or the primary pump is routed from the heat pump's electricity meter to the heat pump. The cable for the heat pump is routed via the utility contactor (if required). Connection of the mains cable is at the control panel of the heat pump via the terminals: X1: L1/L2/L3/N/PE or X1: L10/L20/L30/N0/PE. If no utility contactor is used, the electrical loads are supplied via a shared feed cable (bridge feeds using bridges supplied). The power supplies are fitted with an all-phase disconnection with at least 3mm contact opening distance (e.g. utility protection contactor, power contactor), as well as an all

phase cutout switch, with shared activation of all external conductors (release currents and characteristics in accordance with device information; see circuit diagram for further details).

CAUTION!

Ensure that there is a clockwise rotating field: With incorrect wiring the starting of the heat pump is prevented. A corresponding warning is indicated on the display of the heat pump manager (adjust wiring).

2) The three-core electric supply cable for the heat pump manager (heating controller N1) is fed into the heat pump. Connection of the control line to the control panel of the heat pump via terminal X2: L/N/PE. Details on the power consumption of the heat pump are listed on both the product information sheet and the type plate. The (L / N / PE 230V,50Hz) supply cable for the heat pump manager must have a constant voltage. For this reason, it should be tapped upstream from the utility blocking contactor or be connected to the household current, as important protection functions could otherwise be lost during a utility block.
3) The utility blocking contactor(K22) with 3 main contacts (1 / 3 / 5 / / 2 / 4 / 6) and an auxiliary contact (NO contact 13/ 14) should be dimensioned according to the heat pump output and must be supplied by the customer. The NO contact of the utility blocking contactor (13/14) is looped from terminal strip X3/G to connector terminal X3/ A1. CAUTION! Extra-low voltage!
4) The contactor (K20) for the immersion heater (E10) of mono energy systems (HG2) should be dimensioned according to the radiator output and must be supplied by the customer. It is controlled (230 V AC) by the heat pump manager via terminals X2/N and X2/K20.
5) The contactor (K21) for the flange heater (E9) in the hot water cylinder should be dimensioned according to the radiator output and must be supplied by the customer. It is controlled (230 V AC) by the heat pump manager via terminals X2/N and X2/K21.
6) The contactors mentioned above in points 3, 4 and 5 are installed in the electrical distribution system. Mains cables for the installed heaters must be laid and secured in accordance with the valid standards and regulations.
7) All installed electric cables must have permanent wiring.
8) The heat circulating pump (M13) is activated via the contact N1-J13/NO5. The connection points for the pump are X2/M13 and X2/N. When using pumps where the switching capacity exceeds the output, a coupling relay must be interposed.
9) The auxiliary circulating pump (M16) is activated via the contact N1-J16/NO9. The connection points for the pump are X2/M16 and X2/N. When using pumps where the switching capacity exceeds the output, a coupling relay must be interposed.
10) The domestic hot water circulating pump (M18) is activated via the contact N1-J13/NO6. The connection points for the pump are X2/M13 and X2/N. When using pumps where the switching capacity exceeds the output, a coupling relay must be interposed.
11) The brine or well pump (M11) is activated via the contact N1-J12/NO3. The connection points for the pump are on contactor K5:2/4/6. A coupling relay is already integrated in this output.

12) A return sensor is integrated into the heat pump. The return flow sensor must be installed in the immersion sleeve in the manifold when a dual differential pressureless manifold is used. The single-core wires are then connected to terminals X3/GND and X3/R2.1. Bridge A-R2 (situated between X3/B2 and X3/1 when delivered) must then be moved to terminals X3/1 and X3/2.
13) The external sensor (R1) is connected to terminals X3/GND and X3/R1.
14) The domestic hot water sensor (R3) is included with the domestic hot water cylinder and is connected to terminals X3/GND and X3/R3.

7.5.3 Connecting an electronically regulated circulating pump

Electronically regulated circulating pumps have high starting currents, which may shorten the service life of the heat pump manager. For this reason, a coupling relay is installed or must be installed between the output of the heat pump manager and the electronically regulated circulating pump. This is not necessary if the permissible operating current of 2 A and a maximum starting current of 12 A are not exceeded in the electronically regulated circulating pump or if express approval has been issued by the pump manufacturer.

CAUTION!

It is not permitted to connect more than one electronically regulated circulating pump via a relay output.

8 Commissioning

8.1 General Information

To ensure that start-up is performed correctly, it should only be carried out by an after-sales service technician authorised by the manufacturer. These measures can also include an additional warranty under certain conditions (see Warranty).

8.2 Preparation

The following items need to be checked prior to start-up:

The heat pump must be fully connected, as described in Chapter 6.
The heat source system and the heating circuit must have been filled and checked.
All valves that could impair proper flow in the well and heating circuits must be open.
The heat pump manager must be adapted to the heating system in accordance with the controller's operating instructions.

8.3 Start-up Procedure

The heat pump is started up via the heat pump manager.

CAUTION!

The heat pump must be started up in accordance with the installation and operating instructions of the heat pump manager.

If an overflow valve is fitted to assure the minimum heating water flow rate, the valve must be set in accordance with the requirements of the respective heating system. Incorrect adjustment can lead to faulty operation and increased energy consumption. We recommend carrying out the following procedure to correctly adjust the overflow valve:

Close all of the heating circuits that may also be closed during operation (depending on the type of heat pump usage) so that the most unfavourable operating state - with respect to the water flow rate - is achieved. This normally means the heating circuits of the rooms on the south and west sides of the building. At least one heating circuit must remain open (e.g. bathroom).

The overflow valve should be opened far enough to produce the maximum temperature spread between the heating flow and return flow listed in the table below for the current heat source temperature. The temperature spread should be measured as close as possible to the heat pump. The heating element of mono energy systems should be disconnected during start-up.

Heat source temperature		Max. temperature spread between heating flow and return flow
From To
7°C 12	°C 10 K
13°C	18°C	11 K
19°C	25°C	12 K

9 Maintenance and Cleaning

9.1 Maintenance

To prevent faults due to sediment in the heat exchangers, care must be taken to ensure that no impurities can enter either the heat source system or the heating system. In the event that operating malfunctions due to contamination occur nevertheless, the system should be cleaned as described below.

9.2 Cleaning the Heating System

The ingress of oxygen into the heating water circuit may result in the formation of oxidation products (rust), particularly if steel components are used. This oxygen enters the heating system via the valves, the circulating pumps and/or plastic pipes. It is therefore essential - in particular with respect to the piping of underfloor heating systems - that only diffusion-proof materials are used.

NOTE

We recommend the installation of a suitable corrosion protection system to prevent the formation of deposits (e.g. rust) in the condenser of the heat pump. We recommend equipping diffusion-open heating systems with an electrophysical anti-corrosion system (e.g. ELYSATOR system).

Residue from lubricants and sealants may also contaminate the heating water.

In the case of severe contamination leading to a reduction in the performance of the liquifier in the heat pump, the system must be cleaned by a heating technician.

According to today's state of knowledge, we recommend using a 5% phosphoric acid solution for cleaning purposes. However, if cleaning needs to be performed more frequently, a 5% formic acid solution should be used.

In either case, the cleaning fluid should be at room temperature. We recommend flushing the heat exchanger in the direction opposite to the normal flow direction.

To prevent acidic cleaning agents from entering the heating system circuit, we recommend connecting the flushing device directly to the flow and return flow of the liquifier. It is important that the system be thoroughly flushed using appropriate neutralising agents to prevent any damage from being caused by cleaning agent residue remaining in the system.

Acids must be used with great care and all relevant regulations of the employers' liability insurance associations must be adhered to.

The manufacturer's instructions regarding cleaning agent must be complied with at all times.

9.3 Cleaning the Heat Source System

A dirt trap is inserted in the heat source inlet of the heat pump to protect the evaporator against the ingress of impurities. When the system is first put into operation, the filter screen of the dirt trap should be cleaned in relatively short intervals. These intervals can be prolonged once the amount of impurities decreases.

9.4 Water Quality Requirements

The ground water should not contain any substances that could form deposits. The limit values for iron (< 0.2mg / l) and manganese (< 0.1mg / l) must be adhered to prevent iron ochre sedimentation in the heat pump system.

The use of surface water or water containing salt is not permissible. Your local water utility can provide you with general information regarding the possible use of ground water. Water analyses are carried out by specially-equipped laboratories.

It is not necessary to carry out a water analysis with regard to evaporator corrosion if the annual mean temperature of the ground water does not exceed

13 °C). In this case, the limit values for iron and manganese must be adhered to (iron ochre sedimentation).

10 Faults / Trouble-Shooting

This heat pump is a quality product and is designed for trouble-free operation. In the event that a fault should occur, it will be shown on the heat pump manager display. Simply consult the Faults and Trouble-Shooting page in the operating instructions of the heat pump manager.

If you cannot correct the fault yourself, please contact your after-sales service technician.

CAUTION!

Before opening the device, ensure that all circuits are disconnected from the power supply!

After disconnecting the power supply, always wait for at least 5 minutes to allow stored electric charges to dissipate.

CAUTION!

Any work on the heat pump may only be performed by authorised and qualified after-sales service technicians.

11 Decommissioning / Disposal

Before removing the heat pump, disconnect it from the power source and close all valves. The heat pump must be installed by trained personnel. Observe all environmentally-relevant requirements regarding the recovery, recycling and disposal of materials and components in accordance with all applicable standards. Particular attention should be paid to the proper disposal of refrigerants and refrigeration oils.
