ATTENTION!

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.

1.4 Energy-efficient use of the heat pump

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 1 K corresponds to an increase in energy consumption of approx. 2.5 %. Low-temperature heating systems with flow temperatures between 30 °C and 50 °C are particularly well-suited for energy-efficient operation.

The domestic hot water temperature should not exceed 45 °C when the heat pump is in operation. This will save you significant amounts of energy.

2 Intended use of the heat pump

2.1 Intended purpose

The high-efficiency compact brine-to-water heat pump with built-in domestic hot water cylinder is intended only for heating water and process water. It can be used in new or existing heating systems. The mixture of water and frost protection (brine) acts as a heat transfer medium in the heat source system. Ground probes, ground heat collectors or similar systems can be used as heat source systems.

2.2 Operating principle

The heat generated by the sun, wind and rain is stored in the ground. This heat stored in the ground is collected at a low temperature by the brine circulating in the ground heat collector, the borehole heat exchanger or a similar system. A circulating pump then conveys the "heated" brine to the evaporator of the heat pump. There the heat is given off to the refrigerant in the refrigerating cycle. This cools the brine so that it can once again absorb thermal energy in the brine 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.

The refrigerant subsequently passes through the liquifier where it transfers its thermal energy to the heating water. Depending on the set operating point, the heating water is thus heated up to a max. of 62 °C.

3 Basic device

3.1 General

The basic device consists of a ready-for-use heat pump for indoor installation in a compact design with built-in domestic hot water cylinder.

All components required for the operation of the heat pump are located on the switch box with heat pump manager. An outside 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 by the customer.

The customer must provide both the heat source system and the brine circuit manifold.

1) Brine-to-water hydraulic module

2) Switch box with heat pump manager

3) Heat pump module

3.2 Brine-to-water hydraulic module

The brine-to-water hydraulic module contains the components of the heating and brine circuit required for connecting the heat pump.

1) De-aeration
2) Heating pressure gauge
3) Brine pressure gauge
4) Domestic hot water cylinders
5) Overflow valve
6) Pipe heater
7) Heat circulating pump
8) Brine circulating pump

Fig. 4.1: Set-up of the brine circuit manifold or collector The collector or heat exchanger pipes must be inserted into the manifold from below in a bend (without tension), so that it is possible to compensate any length differences occurring between the summer and winter months (tension cracks).

4.2 Brine controller

If required by the authorities, the brine controller must be incorporated in the heat source main line (brine accessories package) as follows.

4.3 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.

4.4 Building management technology

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

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

Modbus
EIB, KNX
Ethernet

ATTENTION!

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.

4.5 Smart RTC

The Smart RTC is a room temperature controller with a display, which is used both to display the current room temperature and to set the desired room temperature. It is available in a surface-mounted version (RT Econ A) and a flush-mounted version (RT Econ U). Temperature sensors for measuring the room temperature are already integrated into both versions.

The supplementary installation instructions of the Smart RTC must be consulted regarding its installation and operation.

ATTENTION!

Before start-up, the transport fastening must be removed.

6 Installat

6.1 General Information

The compact brine-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. The surface must have sufficient load bearing capacity for the weight of the heat pump and the domestic hot water quantity. 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, where necessary, at the sides of the heat pump. If the heat pump is accessed from the front (e.g. installed in a recess etc.), the heat pump module can be removed for after-sales service (see Chapter 5).

Neither frost nor temperatures higher than 35 °C 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 Installat

7.1 General

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

■ Flow and return of the brine (heat source system)
■ Flow and return of the heating system
■ Domestic hot water outlet
Cold water inlet
■ Voltage supply
■ Temperature sensor

i7.2 Connection on heating side

ATTENTION!

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 liquefier may cause the heat pump to completely break down.

Once the heat pump has been connected to the heating system, it must be filled, de-aerated and pressure-tested.

ATTENTION!

The maximum test pressure in the heating circuit and the brine circuit is 4.0 bar.

This value must not be exceeded.

The following points must be observed when filling the system:

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

Scale formation in domestic hot water heating systems cannot be avoided, but in systems with flow temperatures below 60 °C, 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 °C 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.

Total heat output in kW	Total alkaline earths in mol/m ^3 and/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	< 0,11 ^1
50 - 200	≤ 2,0	≤ 11,2	≤ 8,4
200 - 600	≤ 1,5	≤ 8,4	< 0,11 ^1
> 600	< 0,02	< 0,11 ^1

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

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

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.

ATTENTION!

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

The minimum heating water flow through the heat pump must be assured in all operating states of the heating system.

This can be achieved using a heating circuit which is continuously open, e.g. in a reference room which is regulated using a room temperature controller (available as a special accessory).

(see integration diagram Cap. 4.1 on pag. XIV)

NOTE

System faults may result if this is not observed.

The frost protection function of the heat pump manager is active whenever the heat pump manager and the heat circulating pumps are ready for operation. The system must be drained if the heat pump is taken out of service or in the event of a power failure. If heat pump systems are implemented in buildings where a power failure cannot be detected (holiday homes etc.), the heating circuit should be operated with suitable frost protection.

The domestic hot water volume should be checked by the heating system technician. An additional expansion vessel and a safety valve must be installed by the customer (according to DIN 4751, Part 1). The tables listed in the manufacturers' catalogues simplify dimensioning the system on the basis of the water content.

7.3 Heat source connection

The following procedure must be observed when making the connection:

Connect the brine pipe to the heat pump flow and return.

An additional expansion vessel and a safety valve must be installed by the customer (according to DIN 4751, Part 1).

The hydraulic integration diagram must be adhered to.

The dirt trap included in the scope of supply must be inserted in the brine inlet of the heat pump by the customer.

The brine liquid must be produced prior to charging the system. The liquid must have a brine concentration of at least 25 % to ensure frost protection down to -14 °C.

Only monoethylene glycol or propylene glycol-based antifreeze may be used.

The heat source system must be de-aerated and checked for leaks.

ATTENTION!

The brine solution must contain at least a 25% concentration of a monoethylene glycol or propylene glycol-based antifreeze, which must be mixed before filling.

ATTENTION!

A suitable de-aerator (micro bubble air separator) must be installed in the heat source circuit by the customer.

7.4 Domestic hot water connection

7.4.1 General

Installation and commissioning must be performed by an authorised specialist company. The entire system, including all factory-assembled components, should be inspected to ensure that everything is working properly and that there is no leakage. The enamelled steel complying in accordance with DIN 4753 is suitable for normal drinking water.

The following materials can be used in the consumer's domestic hot water system:

Copper
Stainless steel
Brass
Plastic

Depending on the materials used in the domestic hot water system (customer installation), material incompatibility may lead to corrosion damage. This especially applies to zinc-plated materials and materials containing aluminium. If there is a risk of water contamination during operation, it may be necessary to install a filter.

The maximum permissible operating overpressure indicated on the type plate must not be exceeded. It may be necessary to mount a pressure reducer.

NOTE

To compensate for pressure fluctuations or water shocks in the cold water network and to prevent unnecessary pressure loss, a closed expansion vessel with flow fitting must be mounted.

7.4.2 Commissioning

Ensure that the water supply is turned on and the cylinder is filled before start-up.

The domestic hot water cylinder must be equipped with a certified, spring-loaded membrane safety valve by the customer. A shut-off device must not be installed between the cylinder and the safety valve. The operational reliability of the valve must be checked at regular intervals. We recommend having an annual service inspection carried out by a qualified specialist company.

7.5 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)
■ Return temperature primary circuit (R6) installed (NTC-10)
■ Domestic hot water temperature (R3) installed (NTC-10)

7.5.1 Sensor characteristic curves

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. 10. The only exception is the external temperature sensor included in the scope of supply of the heat pump (see Fig.7.3 on pag. 10)

Fig. 7.2: Sensor characteristic curve NTC-10

Fig. 7.3: Sensor characteristic curve NTC-2 according to DIN 44574 Outdoor temperature sensor

7.5.2 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

7.6 Electrical connection

7.6.1 General

All electrical connection work must be carried out by a trained electrician or a specialist for the specified tasks in accordance with the

■ installation and operating instructions,
■ country-specific installation regulations (e.g. VDE 0100),
■ technical connection conditions of the energy suppliers and supply grid operators (e.g. TAB) and
■ 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; N1-J24 and the terminal strips X3. If, due to a wiring error, the line voltage is mistakenly connected to these terminals, the heat pump manager will be destroyed.

7.6.2 Electrical Installation

1) The five-core electrical supply cable for the output section of the heat pump is fed from the heat pump meter via the utility company blocking contactor (if required) into the heat pump.

The mains cable is connected at the heat pump switch box using terminals X1: L1/L2/L3/N/PE.

The enclosed mini-grip bag contains four links that have to be connected to terminal X1 (L1-L10, L2-L20, L30-L3, N-N0) as shown in the circuit diagram (see appendix). There is no need for these links if two separate five-core supply cables are used (see appendix).

An all-pole disconnecting device with a contact gap of at least 3 mm (e.g. utility company blocking contactor or power contactor) as well as an all-pole circuit breaker with common tripping for all external conductors must be installed in the power supply (tripping current and characteristic in compliance with the device information).

ATTENTION!

Only applies to the SIW 6TES:

Ensure the rotary field is clockwise when connecting the mains cables (if the rotary field is not clockwise, the heat pump will not work properly, is very loud and may cause damage to the compressor).

Only applies to the SIW 8TES and SIW 11TES:

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 switch box of the heat pump via terminals 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 \~230 V, 50 Hz) 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 terminal X3/A1.

CAUTION! Extra-low voltage! The contactor is 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.

4) All installed electric cables must have permanent wiring.

5) The external sensor (R1) is connected to terminals X3/GND (ground) and X3/R1.

7.6.3 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. A coupling relay is therefore 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 maximum permissible operating current of the heat pump manager of 2 A and the maximum permissible starting current of the heat pump manager of 12 A are not exceeded by the electronically regulated circulating pump or a relevant approval has been issued by the pump manufacturer.

ATTENTION!

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

8 Commissioning

8.1 General

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 must be checked prior to start-up:

All of the heat pump connections must be installed as described in chapter 7.
- The heat source system and the heating circuit must have been filled and checked.
- Dirt traps and breathers must be inserted in the brine inlet of the heat pump.
All valves that could impair proper flow in the brine and heating circuits must be open.
The heat pump manager must have been parametered for the relevant hydraulics in accordance with its operating instructions.

8.3 Start-up procedure

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

ATTENTION!

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

The overflow valve must be adjusted to 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 set the overflow valve correctly:

Close all of the heating circuits that may also be closed during operation so that the most unfavourable operating state - with respect to the water flow - 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 heat flow and heat return flow listed in the following table 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.

9 Cleaning / maintenance

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. These enter 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 event of severe contamination leading to a reduction in the performance of the liquefier in the heat pump, the system must be cleaned by a heating technician.

Based on current knowledge, we recommend carrying out the cleaning with a 5 % phosphor acid or, if more frequent cleaning is required, with a 5 % formic acid.

In both cases, the cleaning fluid should be at room ture. 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 of the liquifier. It is then 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 care and the 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

ATTENTION!

The supplied dirt trap must be inserted in the heat source inlet of the heat pump to protect the evaporator against the ingress of impurities.

The filter sieve of the dirt trap should be cleaned one day after start-up. Further checks must be set according to the level of dirt. If no more signs of contamination are evident, the filter can be removed to reduce pressure drops.

10 Faults / troubleshooting

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 indicated on the heat pump manager display. In this case, consult the "Faults and troubleshooting" page in the operating instructions of the heat pump manager.

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

ATTENTION!

Work on the heat pump must only be authorised and qualified after-sales service technicians!

ATTENTION!

Disconnect all electrical circuits from the power source prior to opening the device.

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 environmental 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 refrigerant oils.
