General information

1.2. General information

By purchasing this system you have acquired a modern and efﬁ cient heating system. Ongoing qual- ity controls and improvements as well as functional checks at the plant guarantee you technically perfect equipment.

Please read through this documentation carefully. It contains important information for correct installation and safe and economical operation of the system.

1.3. Safety Instructions

Installation and maintenance work can be hazardous due to high system pressure, high temperatures and live parts and may only be operated by specialist staff.

Heat pumps may only be installed by competent specialist staff and commissioned by a customer service company trained to do so by IDM-Energiesysteme GmbH.

When working on the heat pump, the system must be deactivated and secured against reactivation.

In addition, all safety instructions in the relevant documentation, stickers on the heat pump itself and all other applicable safety regulations must be observed.

1.4. Transport

During transport, the heat pump must never be inclined more than 30°. The heat pump must not be transported on the connection ﬁ ttings. The transport packaging may only be removed if the heat pump is located at its installation location.

1.5. Sound Emission

TERRA heat pumps are very quiet in operation thanks to their design. It is however important that the site of the heater is situated as far as possible from noisesensitive living areas. A noise-insulating door should be ﬁ tted door.

1.6. Construction drying and screed heating

The heat pump is not designed for the increased heat requirements when drying out construction work or heating plaster or screed. This must be covered by equipment to be provided by the customer if required.

1.7. Servicing and Maintenance

Regular maintenance as well as checking and servicing of all system components guarantee its safe and economical operation in the long term. To achieve this, we recommend a maintenance contract with the relevant customer service company.

1.8. Cleaning

If necessary, the TERRA heat pump can be cleaned with a damp cloth. The use of cleaning agents is not recommended.

1.9. Installing Additional Components

The installation of additional components which have not been tested with the equipment may impair function. No liability is accepted and the guarantee becomes void in the event of damage caused for this reason.

General instructions on assembling the heat pump.

Space for customer service telephone number

Heatpumps are electrical equipment made from high valuable materials, which are not allowed to be disposed like normal household garbage, but have to be disposed professional and proper according the regulations of the local authorities.

A non-proper disposal can cause, apart from sanctions for the violator, environmental damages and harm for your health.

- The TERRA heat pumps should be

installed in a frost-proof room. (Room temperature should be between 5°C and 35°C)

- In case of a ﬂ oating ﬂ oor screed the screed and

the sound damping around the heat pump have to be omitted.

- Heat pumps should not be installed in wet rooms

or in potentially dust or explosion-endangered rooms.

- Gas from refrigerants in plant rooms must not es-

cape into vicinal rooms, stair rooms, courtyards, walks or into the drainage system of the building. The gas has to be channelled off safely.

- In case of danger, the plant room has to be eva-

cuated immediately.

- For powering off the cooling facility, a remote

power-off switch has to be installed nearby the door of the plant room.

- In case a natural ventilation is not possible, a

mechanical ventilation has to be provided. A mechanical ventilation has to be equipped with an independent emergency control outside of the machine room near the door.

Note for the installation of the heatpump follow all effective national and international piping- and installation rules

same as rules for accident prevention and safety regulations when installing pipeline systems and electrical components and equipment as well as the instructions of this Installation instruction.

Thereto belongs among other things:

- the general effective rules for accident prevention and safety regulations

- the regulations for environmental protection

- the provisions/regulations of the professional associations.

- the effective laws, standards, guidelines and regulations e.g. DIN,EN,DVGW,VDI and VDE

- regulations of the local suppliers/supply companies

Description

2. Description

2.1. Description

Heat pump with suction gas cooled scroll compressor with generously sized stainless steel heat exchangers as evaporator and condenser built on a robust frame and ﬁ tted with a heat and soundproof casing. The heat pump also contains an electrical panel with the Navigator Control and with all the switching and safety mechanisms built-in.

The heat pump has a compact design, the evaporator is already ﬁ tted in the heat pump housing. The heat pump is ﬁ lled with refrigerant and checked to ensure it functions correctly. It is suitable for brine circuit surface collectors, brine circuit deep boreholes, as well as for ground water use.

2.2. Application range

For the monovalent heating of detached and semidetached houses with geothermal heat utilisation. When doing so the house should be ﬁ tted with a low temperature heating system (e.g. underﬂ oor heating, wall heating, low temperature radiator heating).

TERRA heat pumps work with the safety refrigerants R 407 C or R 134 A which, when properly installed and commissioned, circulate in a closed circuit and therefore have virtually no environmental impact.

2.7. Operating Limits

TERRA-S/W heat pumps may only be used with heat conducting media, brine or ground water. Other heat conducting media are not allowed.

Furthermore, the heating of other liquids as heating water is not permitted (heating water quality see Page 25).

By deﬁ nition, heat pumps are subject to pressure or temperature-dependent operating limits (see diagram).

The operation of the TERRA heat pump outside these operating limits is not allowed.

Note:

- The following safety mechanisms are provided for the safety of the heat pump against potential malfunctions:

- Combined high and low pressure switch with automatic locking or unlocking by switching the system off and on (after 3 errors within 24 hours).

- Flow maximum temperature limit with automatic reset via the Navigator Control.

- Start-up current limiter with rotating ﬁ eld monitoring, motor current monitoring and phase monitoring for the compressor.

Heating side installation

Use ﬂ exible connection hoses.

3.1. Installation

The installation of the TERRA heat pump must be undertaken in a frost-proof room by an approved specialist company. Whilst doing so, the room temperature must be between 5°C and 35°C.

With regard to the installation room requirements please observe EN 378 Part 1 and 2.

Installation in wet rooms, in rooms at risk from dust or explosions is not permitted.

In order to avoid structure-borne sound transmissions, the TERRA heat pump must be installed on a horizontal, level and weight-bearing surface (concrete plate or similar). In the case of ﬂ oating screed, the screed and the impact sound insulation must be recessed around the heat pump to ensure low noise levels when the heat pump is operating.

The applicable laws, regulations and standards must be observed, in particular EN 378 Part 1 and 2 as well as BGV D4.

The ﬂ exible connection hoses for heat pump ﬂ ow and return, as well as for brine inlet and outlet, are used to avoid the transmission of noise via the piping. The connection hoses must not be bent.

For a horizontal installation of the TERRA heat pump, adjustable feet are installed in the columns.

A distance of 60 cm must be maintained at the front and on the right-hand side of the heat pump (see the diagram below).

3.2. Installation Heating Side

The relevant laws, regulations and standards for machine room piping and for heat pump systems must also be observed.

- In the heating return, before the heat pump, it is essential to install a dirt trap. Depending on the water quality it is recommended to ﬁ t an additional silt trap.

- Safety devices and expansion devices for closed heating systems according to EN 12828 must be ﬁ tted.

- Pipe dimensions must conform to the required ﬂ ow volumes (see section 2.6, Technical data, page 8 cont.).

- The charging pump is not included in the scope of delivery. The recommended charging pump must be installed on-site in the heat pump ﬂ ow.

- Connection hoses supplied for the heat pump ﬂ ow and return lines must always be installed. The connection hoses can be cut to the required length, but not shorter than 60 cm. In addition, the connection hoses must not be bent.

- Venting options should be ﬁ tted at the highest points of the connection lines, and draining options at the lowest points.

- To avoid heat loss, connection lines should be insulated using suitable material.

Oxygen diffusion

With plastic pipe underﬂ oor heating or open heating systems which are not diffusion-tight, corrosion may occur on steel parts when using steel pipes, steel radiators or storage tanks due to oxygen diffusion.

Corrosion products can be deposited in the condenser and may cause heating losses in the heat pump or high-pressure faults.

For this reason, open heating systems or steel pipe installations in combination with plastic pipe underﬂ oor heating which is not diffusion-tight should be avoided.

Heating water quality

Depending on the quality of the heating water, lime scale may occur (adherent coating primarily consisting of calcium carbonate) on heat exchanger surfaces in particular, i.e. with a high proportion of calcium hydrogen carbonate there is an increased risk of lime scale forming.

For ﬁ lling heating systems, very clear guidelines apply relating to the heating water quality. Speciﬁ cally, Eu- ropean standard EN 12 828, ÖNORM H 5195 and in particular VDI Guideline no. 2034-1 must be observed and represent the current state of art.

You must also check the pH value of the heating water; it should be between 8 and 9.5.

4.1. Power supply

Electrical connection must be registered with the relevant power supply company.

The required series-connected fuse for the primary circuit can be calculated from the technical data (starting current compressor) and the power consumption of the on-site brine/ground water pumps installed, as well as any circulation pump.

It is essential that a “slow-blow” design is used (“C” or "K" characteristic). The relevant cable cross section must be determined by the electrician.

All systems are ﬁ tted with a start-up current limiter that also monitors the power consumption and the phasing.

A power protection switch is already ﬁ tted for the brine or ground water pump. In particular it is recommended to install a suitable motor protection switch in the supply line to the brine or ground water pump especially in the case of large heat pump systems.

The heat pump is operated via the Navigator Control.

Depending on system design, the relevant sensors are required; see the connection diagrams on the following pages for more information.

For reliable operation of the heat pump, the voltage in the mains network must be within speciﬁ c tolerance limits, between 360 and 430 V (check with the relevant power supply company if necessary).

4.3. Disassembly Cover

Prior to the electrical connection, the plastic cover must be removed. After having done this the connection terminals are freely accessible. The connection for the control and primary circuit is designed separately.

Loosen the screws on the plastic cover and under the yellow ﬂ ap and remove the plastic cover.

The system must only be connected to the mains and put into operation if the entire heating system has been ﬁ lled and bled or the circulating pumps may run dry.

When disassembling the cover, if the control unit has already been connected it must be ensured that the connection cable between the control unit and the central unit is only approx. 1m long. When removing the cover, the connection cable must not be pulled. In order to remove the cover completely , the connection cable must be disconnected.

- Before removing the plastic cover disconnect the system from the mains.

- Before starting the system, check that the pumps are soft running.

- Before commissioning the system, tighten the terminals.

4.4. Power Supply Connection

The power supply connection of the primary circuit takes places directly on the main switch Q1.

Control power connection: 1 x 230 V/50 Hz Primary power connection: 3 x 400 V/50 Hz

The supply lines must have the relevant thickness. For more information, see technical data point on page - max. power consumption.

All other connections must be established directly on the microprocessor control board or are already factory set (see the following pages).

The electrical wiring of additional devices on the output terminals on the control board must be done using ﬂ exible cables 1.5 mm². End sleeves must be used for the cabling.

4.5. Heat Source Pump Connection

The line cross section for the connection of the brine circuit or ground water pump must be sized according to technical data.

It is possible to connect both single-phase and threephase brine circuit or ground water pumps.

In the case of single-phase brine circuit or ground water pumps, the terminals 7/L; 10/N; 1 1/Pe are used for connection.

The motor protection for brine/ground water pump must be carried out on-site.

4.6. EMC

Please take note of the following with regard to this issue: Electro-Magnetic Compatibility (EMC) demands additional work and expertise from all manufacturers and operators of modern electrical technology and electronics year on year.

As the number of electronic devices in use increases continually, the number of potential sources of interference also increases. A combination of cables from the power supply company , transmission stations and other communications devices generate an invisible “electrosmog".

This interference affects all systems, both biological (us as living beings) as well as technical electrical systems. They generate undesirable fault currents which can have different effects.

The effects on biological systems can only be guessed at currently , but the ef fects on technical electrical systems are measurable, and in the worst case, visible as well.

The faults can have different effects:

- Short-term measurement faults

- Permanent measurement faults

- Short-term interruption in data connections

- Permanent interruption in data connections

- Data losses

- Damage to equipment

Potential sources of interference are essentially all technical electrical systems, e.g. contactor coils, electric motors, transmitters, mains and high-voltage lines, etc., and the equipment can be affected via different coupling routes (galvanic, inductive, capacitive, via radiation).

As far as we are concerned, everything has been done to protect the Navigator Control from interference (Hardware design, EMI-proof electrical panel, network ﬁ lter, etc.). In particular, it is the responsibility of the electrician to prevent possible coupling paths when setting up the electrical installation.

4.7.1. Sensor design

Sensor lines have a cable cross section of 0.75 mm² as standard.

The sensor positions are shown in the relevant installation diagram. Reliable operation can only be ensured by correct positioning and good heat transfer (heat conducting paste).

If necessary, the sensors can be extended using a suitable cable. It must be ensured that the connection is clean and corrosion-free

Sensor lines should be run separately from mains cables, (see EMC issue).

4.7.2. Sensor equipment

The following sensors are contained in the scope of delivery or are already installed and, in any case, required:

- Outside sensor, B32

- Heat pump heat ﬂ ow sensor, B 33

- Buffer tank sensor (Return sensor heat pump), B39

- Heat source outlet sensor, B36

- Flow sensor heating circuit A, B51

- HW tap - temperature sensor, B42

- Hygienik sensor, B41

(All other sensors are optional depending on the system equipment).

4.7.3. Flow temperature sensor

The ﬂ ow temperature sensors for the heating circuits used are required in every case. They must be connected on the corresponding ﬂ ow lines and in accord- ance with the connection diagram.

The ﬂ ow sensors for the heating circuits C-G are con- nected on the respective heating circuit expansion module. (see the installation instructions expansion module for more information)

4.13. Composite signal zone valves

The composite signal zone valve setting generates a request when one of the zone valves is open. The difference to a room thermosta function is that, independently of heating or cooling operations, a request is generated when a zone valve contact is closed.

If you are using zone valves, you can generate composite signal from all zone valves to be able to switch the heating and cooling circuit on and off with the thermostat function.

5.1. Brine Surfaces Collector

5.1.1. Description

With this system, plastic pipes, Ø25 x 2.3 mm, are laid in the soil with a length of 100 m each for heat absorption. Multiple pipework circuits may be required depending on the heat pump size. The brine medium circulates through these pipes. The heat exchange between the brine medium and the refrigerant takes place in the evaporator set (stainless steel plate heat exchanger).

The following is required to connect the brine circuit: brass distributors with shut-off valves, safety valve, pressure gauge, expansion vessel, thermometer and brine circulation pump. The ﬂ exible connection hoses provided must be installed to prevent the transmission of noise. The connection lines between the distributor and heat pump must be set up on-site however no zinc-plated pipes may be used.

The mixing ratio of the brine medium must be selected up to -15°C (= 30% proportion of antifreeze). If too much antifreeze is added the speciﬁ c heat content of the brine medium drops.

Caution! In the case of the circulation pump, the electrical conduit box must not be positioned downwards. The pump head (Motor) must not be insulated.

5.1.2. Application range

Suitable for all heat pumps type TERRA .. S/W(H).

5.1.3. Scope of delivery

- Plastic piping Ø 25 x 2.3 mm in rings for each 100 m, number of rings depends on the heat pump performance.

- Connection unit with

• Flow and return distributor with shut-off valve for each circuit

• Safety valve

• Pressure gauge

• 2 thermometers

• Expansion vessel

• Brine circulation pump

Notes:

- Only antifreeze approved by IDM-Energiesysteme GmbH may be used.

- Brine circuit lines must be provided with steam diffusion-tight insulation in the event of the formation of condensation and the accumulation of ice (e.g. Armaﬂ ex).

- Brine circuit pump and brine circuit expansion vessel must be positioned on the heat pump inlet side (warm side).

- The brine circuit expansion vessel must be connected from the brine line upwards.

- When ﬁ lling the brine circuit with antifreeze mix, the expansion vessel must be ﬁ lled (due to a reduction in volume during cooling when in operation).

5. Heat source

In many countries, geothermal utilisation must be approved by the water authorities. The relevant application should be made on time.

The identiﬁ ed surface requirement for geothermal pumps is based on average soil conditions (soil, loam). In the case of poor soil (stony), the required line length, therefore also the surface, should be enlarged and the pipes should be embedded in ﬁ ne-grained sand (cable sand 0.3 to 0.5 mm).

Contact your IDM partner for more information.

Note

- The installation should take place several months before the heating period. Corresponding preparation times need to be taken into account during the overall planning process.

- Plants with deep-growing root structures must be avoided in all cases.

- Rainwater must not be diverted using drainage as it is required to regenerate the ground.

- When back-ﬁ lling, a signal band of approx. 0.5 above the pipeline should be laid to avoid subsequent damage.

- In the case of surface collectors, the overlying surface must not be closed off (e.g. by asphalting).

5.4. Ground water use

5.4.1. Description

In this system, ground water is used as a source of heat. When using ground water, the water is pumped out of an intake well, cooled in the evaporator and supplied via an injection well back to the ground water. Whilst doing so, it must be ensured that the injection well is located in the ground water direction of ﬂ ow after the intake well.

The heat exchange between the water and the refrigerant takes place in the evaporator (stainless steel plate heat exchanger).

During this process, in order to protect the evaporator, there must be a minimum temperature limit as well as the installation and connection of a ﬂ ow switch.

The ﬂ exible connection hoses provided must be installed to prevent the transmission of noise. The ground water lines must be set up on-site.

Notes

In the event of increased solids content in the well water (sand, sludge), the corresponding sedimentation basin must be provided to prevent blocking the evaporator (possibly safety heat exchanger).

- Ensure that the inlet and outlet lines are laid as frost-proof, with an incline to the well.

- The lines in the house must be insulated against the formation of condensation.

- From the intake well up to the heat pump, a protec- tion pipe is also required with an electric line for the well pump.

- Ensure that the well cover is light and airtight to prevent the formation of algae and sludge accumulation.

- A submersible pump is recommended as the well pump.

- After being set up, the well should be rinsed for ap- prox. 48 hours.

5.4.2. Application range

Water inlet temperature: at least + 7 °C (Danger of icing up)

Ground water quality:

The following values must be observed:

- ph-value: 6,5 - 9

- Chloride: < 100 mg/kg

- Sulphates: < 50 mg/kg

- Nitrates: < 100 mg/kg

- Manganese: < 0.1 mg/kg*

- Free carbon dioxide: < 20 mg/kg

- Ammonia: < 2 mg/kg

- Iron: < 0.2 mg/kg*

- Free Chloride: < 0.5 mg/kg

- Electrical conductivity : > 50 mS/cm und < 600 mS/cm

- Oxygen < 2 mg/kg*

* * If these limit values are exceeded, this could cause sludge to build up on the evaporator and the inlet lines, as well as obstructing the injection well

In order to verify the water temperature, and the water volume and quality , a test well and a pump trial is recommended over 48 hours. The test should preferably be carried out at the end of February.

To avoid corrosion and frost damage of the plate heat exchanger located in the heat pump, IDMEnergiesysteme instruct to instal a safety heat exchanger for al ground water plants. Here the heat pump groundwater circuit is decoupled via a safety heat exchanger by a brine circuit. This means that any damage in the groundwater circuit or in the safety heat exchanger does not result

in any additional damage to the heat pump.
