1.4 Energy-efficient use of the heat

pump By operating this heat pump you are helping to protect our en-vironment. Both the heating system and the heat source mustbe properly designed and dimensioned to ensure efficient op-eration. It is particularly important to keep water flow tempera-tures as low as possible. All connected energy consumersshould therefore be suitable for low flow temperatures. Raisingthe heating water temperature by 1 K corresponds to an in-crease in energy consumption of approx. 2.5 %. Low-tempera-ture heating systems with flow temperatures between 30 °Cand 50 °C are particularly well-suited for energy-efficient oper-ation.The domestic hot water temperature should not exceed 45 °Cwhen the heat pump is in operation. This will save you signifi-cant amounts of energy.www.gdts.one 452236.66.09 · FD 9912 EN-3 SIW 6TES - SIW 11TES English 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 heat- ing 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 tem- perature 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 compres- sor, 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. 3Basic device

The basic device consists of a ready-for-use heat pump for in- door 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 cur- rent 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

3.2 Brine-to-water hydraulic

module The brine-to-water hydraulic module contains the componentsof the heating and brine circuit required for connecting the heatpump.1) De-aeration2) Heating pressure gauge3) Brine pressure gauge4) Domestic hot water cylinders5) Overflow valve6) Pipe heater7) Heat circulating pump8) Brine circulating pump9) Domestic hot water circulating pump

3.3 Heat pump module

The refrigeration circuit is "hermetically sealed" and containsthe fluorinated refrigerant R410A included in the Kyoto proto-col. Information on the GWP value and CO equivalent of therefrigerant can be found in the chapter Device information. Therefrigerant is CFC-free, non-ozone depleting and non-combus-tible.The heat pump module switch box contains all components re-quired for operating the refrigeration circuit.10) Compressor11) Liquefier12) Evaporator13) Filter dryer14) Compensation pipe

The brine circuit manifold combines and connects the individ-ual collector or exchanger loops to create a main line con-nected to the heat pump. The built-in ball valves can be closedoff individually for de-aerating or emptying the brine circuits.Fig. 4.1: Set-up of the brine circuit manifold or collectorThe collector or heat exchanger pipes must be inserted into themanifold from below in a bend (without tension), so that it ispossible to compensate any length differences occurring be-tween the summer and winter months (tension cracks).

4.2 Brine controller

If required by the authorities, the brine controller must be incor-porated in the heat source main line (brine accessories pack-age) as follows.

A remote control adds convenience and is available as a specialaccessory. Operation and menu navigation are identical tothose of the heat pump manager. Connection takes place via aninterface (special accessories) with RJ 12 Western plug. NOTE

In the case of heating controllers with a removable operatingelement, 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 man-agement system network via supplementation of the relevantextension. The supplementary installation instructions of theextension must be consulted regarding the exact connectionand 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 controlledexternally, an flow rate switch is required to prevent thecompressor from being switched on when there is no volumeflow.

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 (RTEcon U). Temperature sensors for measuring the room tem-perature are already integrated into both versions. The supplementary installation instructions of the Smart RTCmust be consulted regarding its installation and operation. SWPR 200EN-6 452236.66.09 · FD 9912 www.gdts.one English SIW 6TES - SIW 11TES 5Transport

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

In installed and dismantled state, the heat pump module mayonly be tilted by a maximum of 45° (in each direction) ( seeCap. 5.3 on pag. 7).

5.2 Removing the casing panels

All panelling can be removed to allow accessing the inside ofthe device.Fig. 5.1: open front plate bottomFig. 5.2: open front plate topFig. 5.3: open side plates

Removing the heat pump module enables to heat pump to betransported easily in a horizontal position and the heat pumpmodule to be transported separately. ATTENTION!

In installed and dismantled state, the heat pump module mayonly be tilted by a maximum of 45° (in each direction).After transportation, the transport fastening on the heat pumpmodule is to be removed from both sides. ATTENTION!

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

The compact brine-to-water heat pump must be installed in afrost-free, dry room on an even, smooth and horizontal surface.The entire base of the frame should lie directly on the floor toensure an adequate soundproof seal. The surface must havesufficient load bearing capacity for the weight of the heat pumpand the domestic hot water quantity. If supporting feet areused, the heat pump must be installed horizontally. In this case,the specified sound level can be up to 3 dB(A) higher, and addi-tional sound insulation measures may be necessary.The heat pump must be installed so that maintenance work canbe carried out without hindrance. This can be ensured by main-taining a clearance of approx. 1 m in front of and, where neces-sary, at the sides of the heat pump. If the heat pump is ac-cessed from the front (e.g. installed in a recess etc.), the heatpump module can be removed for after-sales service (seeChapter 5).Neither frost nor temperatures higher than 35 °C must occur inthe installation location at any time of the year.

6.2 Acoustic Emissions

The heat pump operates silently due to efficient sound insula- tion. Internal insulation measures should be carried out to pre- vent vibrations from being transmitted to the foundation or tothe heating system. 7Installation

The following connections need to be established on the heatpump: 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

7.2 Connection on heating side

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 theliquefier may cause the heat pump to completely break down.Once the heat pump has been connected to the heating sys-tem, it must be filled, de-aerated and pressure-tested. ATTENTION!

The maximum test pressure in the heating circuit and thebrine 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 µm).Scale formation in domestic hot water heating systems cannotbe avoided, but in systems with flow temperatures below 60 °C,the problem can be disregarded. With high-temperature heatpumps and in particular with bivalent systems in the higher per-formance range (heat pump + boiler combination), flow tem-peratures of 60 °C and more can be achieved. The followingstandard values should therefore be adhered to with regard tothe 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 withVDI 2035For systems with an above-average specific system volume of50 l/kW, VDI 2035 recommends using fully demineralizedwater and a pH stabiliser to minimize the risk of corrosion in theheat pump and the heating system. ATTENTION!

With fully demineralized water, it is important to ensure thatthe minimum permissible pH value of 7.5 (minimumpermissible value for copper) is complied with. Failure tocomply with this value can result in the heat pump beingdestroyed. )m 1()m 1(

pumps.www.gdts.one 452236.66.09 · FD 9912 EN-9 SIW 6TES - SIW 11TES English Minimum heating water flow The minimum heating water flow through the heat pump mustbe assured in all operating states of the heating system. This can be achieved using a heating circuit which is continu-ously 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 ac-tive whenever the heat pump manager and the heat circulatingpumps are ready for operation. The system must be drained ifthe heat pump is taken out of service or in the event of a powerfailure. If heat pump systems are implemented in buildingswhere a power failure cannot be detected (holiday homes etc.),the heating circuit should be operated with suitable frost pro-tection.The domestic hot water volume should be checked by the heat-ing system technician. An additional expansion vessel and asafety valve must be installed by the customer (according toDIN 4751, Part 1). The tables listed in the manufacturers’ cata-logues simplify dimensioning the system on the basis of thewater content.

7.3 Heat source connection

The following procedure must be observed when making theconnection:Connect the brine pipe to the heat pump flow and return.An additional expansion vessel and a safety valve must be in-stalled 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 inthe 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 % toensure frost protection down to -14 °C.Only monoethylene glycol or propylene glycol-based antifreezemay be used.The heat source system must be de-aerated and checked forleaks. ATTENTION!

The brine solution must contain at least a 25 % concentrationof a monoethylene glycol or propylene glycol-basedantifreeze, which must be mixed before filling. ATTENTION!

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

7.4 Domestic hot water connection

Installation and commissioning must be performed by an au-thorised specialist company. The entire system, including allfactory-assembled components, should be inspected to ensurethat everything is working properly and that there is no leakage.The enamelled steel complying in accordance with DIN 4753 issuitable for normal drinking water.The following materials can be used in the consumer's domes-tic hot water system: Copper Stainless steel Brass PlasticDepending on the materials used in the domestic hot watersystem (customer installation), material incompatibility maylead to corrosion damage. This especially applies to zinc-platedmaterials and materials containing aluminium. If there is a riskof water contamination during operation, it may be necessaryto install a filter.The maximum permissible operating overpressure indicated onthe type plate must not be exceeded. It may be necessary tomount a pressure reducer. NOTE

To compensate for pressure fluctuations or water shocks inthe cold water network and to prevent unnecessary pressureloss, a closed expansion vessel with flow fitting must bemounted.

Ensure that the water supply is turned on and the cylinder isfilled before start-up. The domestic hot water cylinder must be equipped with a certi-fied, spring-loaded membrane safety valve by the customer. Ashut-off device must not be installed between the cylinder andthe safety valve. The operational reliability of the valve must bechecked at regular intervals. We recommend having an annualservice inspection carried out by a qualified specialist company.EN-10 452236.66.09 · FD 9912 www.gdts.one English SIW 6TES - SIW 11TES

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 il- lustrated in Fig.7.2 on pag. 10. The only exception is the exter- nal 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 Out-door 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 meas- ured 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

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 con- nected 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.

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 ca- bles 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 in- stalled in the power supply (tripping current and character- istic 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 rea- son, it should be tapped upstream from the utility blocking contactor or be connected to the household current, as im- portant protection functions could otherwise be lost dur- ing 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

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 in- stalled 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.EN-12 452236.66.09 · FD 9912 www.gdts.one English SIW 6TES - SIW 11TES 8 Commissioning

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

The following items must be checked prior to start-up: All of the heat pump connections must be installed as de- scribed in chapter 7. The heat source system and the heating circuit must havebeen 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 in-structions.

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 theinstallation and operating instructions of the heat pumpmanager.The overflow valve must be adjusted to the requirements of therespective heating system. Incorrect adjustment can lead tofaulty operation and increased energy consumption. We rec-ommend carrying out the following procedure to set the over-flow valve correctly:Close all of the heating circuits that may also be closed duringoperation so that the most unfavourable operating state - withrespect to the water flow - is achieved. This normally means theheating circuits of the rooms on the south and west sides of thebuilding. At least one heating circuit must remain open (e.g.bathroom).The overflow valve should be opened far enough to producethe maximum temperature spread between the heat flow andheat return flow listed in the following table for the current heatsource temperature. The temperature spread should be meas-ured as close as possible to the heat pump. The heating ele-ment of mono energy systems should be disconnected duringstart-up.Heat source temperatureMax. temperature spread between heating flow and return flow of to-5 °C 0 °C 10 K1°C 5°C 11 K6 °C 9 °C 12 K 10 °C 14 °C 13 K 15 °C 20 °C 14 K 21 °C 25 °C 15 Kwww.gdts.one 452236.66.09 · FD 9912 EN-13 SIW 6TES - SIW 11TES English 9 Cleaning / maintenance

To prevent faults due to sediment in the heat exchangers, caremust be taken to ensure that no impurities can enter either theheat source system or the heating system. In the event that op-erating 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 resultin the formation of oxidation products (rust), particularly if steelcomponents are used. These enter the heating system via thevalves, the circulating pumps and/or plastic pipes. It is there-fore essential - in particular with respect to the piping of under-floor heating systems - that only diffusion-proof materials areused. NOTE

We recommend the installation of a suitable corrosionprotection system to prevent the formation of deposits (e.g.rust) in the condenser of the heat pump. We recommendequipping diffusion-open heating systems with anelectrophysical anti-corrosion system (e.g. ELYSATOR system).Residue from lubricants and sealants may also contaminate theheating water.In the event of severe contamination leading to a reduction inthe performance of the liquefier in the heat pump, the systemmust be cleaned by a heating technician.Based on current knowledge, we recommend carrying out thecleaning with a 5 % phosphor acid or, if more frequent cleaningis required, with a 5 % formic acid.In both cases, the cleaning fluid should be at room tempera-ture. We recommend flushing the heat exchanger in the direc-tion opposite to the normal flow direction.To prevent acidic cleaning agents from entering the heatingsystem circuit, we recommend connecting the flushing devicedirectly to the flow and return of the liquifier. It is then importantthat the system be thoroughly flushed using appropriate neu-tralising agents to prevent any damage from being caused bycleaning agent residue remaining in the system.Acids must be used with care and the regulations of the em-ployers’ liability insurance associations must be adhered to.The manufacturer's instructions regarding cleaning agent mustbe complied with at all times.

9.3 Cleaning the heat source

The supplied dirt trap must be inserted in the heat source inletof the heat pump to protect the evaporator against the ingressof impurities.The filter sieve of the dirt trap should be cleaned one day afterstart-up. Further checks must be set according to the level ofdirt. If no more signs of contamination are evident, the filter canbe 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 beindicated on the heat pump manager display. In this case, con-sult the "Faults and troubleshooting" page in the operating in-structions of the heat pump manager.If you cannot correct the fault yourself, please contact yourafter-sales service technician. ATTENTION!

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

Disconnect all electrical circuits from the power source priorto opening the device. 11 Decommissioning / disposal Before removing the heat pump, disconnect it from the powersource and close all valves. The heat pump must be installed bytrained personnel. Observe all environmental requirements re-garding the recovery, recycling and disposal of materials andcomponents in accordance with all applicable standards. Par-ticular attention should be paid to the proper disposal of refrig-erants and refrigerant oils.EN-14 452236.66.09 · FD 9912 www.gdts.one English SIW 6TES - SIW 11TES 12 Device information 1 Type and order code
