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.

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

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.
2.3. Scope of delivery

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.
- Internal winding protection in 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 tted.
- Pipe dimensions must conform to the required 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 under­ 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. Electrical installation
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 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.

4.13. 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.
