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 must be 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 consumers should therefore be suitable for low flow temperatures. Raising the heating water temperature by 1 K corresponds to an in- crease in energy consumption of approx.

2.5 %. Low-temperature heating systems with flow tempera-

tures between 30 °C and 50 °C are particularly well-suited for energy-efficient operation. 2 Purpose of the Heat Pump

The brine-to-water heat pump is to be used exclusively for the heating of heating water. It can be used in new or previously ex- isting heating systems. The mixture of water and frost protec- tion (brine) acts as a heat transfer medium in the heat source system. Ground probes, ground heat collectors or similar sys- tems 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 (thermostat setting), the heating water is thus heated up to a max. of 58 °C. 3Basic Device The basic device consists of a ready-to-use heat pump for in- door installation in a compact design. In addition to the control panel with integral heat pump manager, the device is already equipped with all of the most important components of the heating circuit and the brine circuit: Expansion vessel Circulating pumps Pressure relief valves Pressure gauge Overflow valve (heating circuit) The refrigeration circuit is "hermetically sealed" and contains the fluorinated refrigerant R410A included in the Kyoto proto- col. Information on the GWP value and CO

equivalent of the refrigerant can be found in the chapter Device information. The refrigerant is CFC-free, non-ozone depleting and non-combus- tible. All components required for the operation of the heat pump are located on the control panel. 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.

The brine circuit manifold merges the individual collector loopsof the heat source system into a single main pipe which is con-nected to the heat pump. Integrated ball valves allow the indi-vidual brine circuits to be shut off for de-aeration purposes.

4.2 Brine Controller

If required by the authorities, a low-pressure brine controllercan be installed in the device. In this case, the connection lo-cated upstream from the brine expansion vessel provided forthis purpose is to be used.

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 relevantinterface plug-in card. The supplementary installation instruc-tions of the interface card must be consulted regarding theexact connection and parameterisation of the interface. The following network connections can be made on the heatpump 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. 5 Transport 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!

The heat pump is not secured to the pallet. ATTENTION!

The heat pump must not be tilted more than 45° (in anydirection).Use the holes provided in the sides of the frame to lift the unitwithout the pallet. The side panel assemblies must be removedfor this purpose. Any commercially available length of pipe canbe used as a carrying aid. ATTENTION!

The brine-to-water heat pump must be installed in a frost-free,dry room on an even, smooth and horizontal surface. The entireframe should lie directly on the floor to ensure an adequatesoundproof seal and to prevent the water-bearing componentsfrom becoming too cold. If this is not the case, additional soundinsulation 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 on each sideof the heat pump.La pièce d'installation ne doit jamais être exposée au gel ou àdes températures supérieures à 35 °C.

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

7.1 General Information

The following connections need to be established on the heatpump: Flow and return of the brine (heat source system) Flow for heating and domestic hot water preparation Joint return flow for the heating and domestic hot waterpreparation Return flow of the overflow valve Connection for an additional expansion vessel (accordingto need) Outflows for the pressure relief valves Condensate outflow Voltage supply Temperature sensor

7.2 Heating System Connection

The heat pump is equipped with separate outputs for the heat-ing circuit and the hot water circuit.If the heat pump is not intended to be used to heat up the hotwater, the hot water output must be permanently sealed.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 theliquifier could cause the heat pump to completely break down.An overflow valve is installed in the device for systems in whichthe heating water flow can be shut off via the radiator or ther-mostat valves. This ensures a minimum heating water flow ratethrough the heat pump and helps to avoid faults.Once the heating system has been installed, it must be filled,de-aerated and pressure-tested.Consideration must be given to the following when filling thesystem: Untreated filling water and make-up water must be of drinking water quality (colourless, clear, free from sedi-ments) Filling water and make-up water must be pre-filtered (pore size max. 5µm).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.Total heat output in kWTotal alkaline earths in mol/m³ and/or mmol/lSpecific 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. This value lies outside the permissible value for heat exchangers in heat

pumps.EN-6 452231.66.34 · FD 9912 www.gdts.one English SIK 6TES - SIK 14TES Minimum heating water flow rate The minimum heating water flow rate through the heat pumpmust be assured in all operating states of the heating system.This can be accomplished, for example, by installing either adual differential pressureless manifold or an overflow valve. Theprocedure for adjusting an overflow valve is described in theChapter Start-Up. NOTE

The use of an overflow valve is only recommended for panelheating and a max. heating water flow of 1.3 m³/h. Systemfaults may result if this is not observed.The antifreeze function of the heat pump manager is activewhenever the heat pump manager and the heat circulatingpumps are ready for operation. If the heat pump is taken out ofservice or in the event of a power failure, the system has to bedrained. The heating circuit should be operated with a suitableantifreeze if heat pump systems are implemented in buildingswhere a power failure can not be detected (holiday home).The integrated expansion vessel has a volume of 24 litres. Thisvolume is suitable for buildings with a living space area to beheated of maximum 200 m².The volume should be checked by the heating system techni-cian. If necessary, an additional expansion vessel must be in-stalled (according to DIN 4751, Part 1). The tables listed in themanufacturers’ catalogues simplify dimensioning the systemon the basis of the water content. ATTENTION!

In the case of large-volume heating circuits, an additional expansion vessel must be used to supplement the installedexpansion vessel (24 litres, 1.0 bar admission pressure).

7.3 Heat Source Connection

The following procedure must be observed when connectingthe heat source:Connect the brine pipe to the heat pump flow and return.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 an antifreeze concentration of at least25 % to ensure 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!

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) Flow temperature heating circuit (R9) installed (NTC-10) Flow temperature primary circuit (R6) installed (NTC-10)

7.4.1 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. The only exception is the external temperature sensor included in the scope of supply of the heat pump (see Fig. 7.3) Fig. 7.2:Sensor characteristic curve NTC-10 Fig. 7.3:Sensor characteristic curve, NTC-2 according to DIN 44574 Ex-ternal temperature sensor

7.4.2 Mounting the external temperature

sensor The temperature sensor must be mounted in such a way that all weather conditions are taken into consideration and the measured value is not falsified. Mount on the external wall on the north or north-west side where possible Do not install in a “sheltered position” (e.g. in a wall niche or under a balcony) Not in the vicinity of windows, doors, exhaust air vents, external lighting or heat pumps Not to be exposed to direct sunlight at any time of year

It is only necessary to mount the strap-on sensors if they are included in the scope of supply of the heat pump but have not yet been installed. The strap-on sensors can be fitted as pipe-mounted sensors or installed in the immersion sleeve of the compact manifold. Mounting as a pipe-mounted sensor Remove paint, rust and scale from heating pipe. Coat the cleaned surface with heat transfer compound (apply sparingly). Attach the sensor with a hose clip (tighten firmly, as loose sensors can cause malfunctions) and thermally insulate.

7.4.4 Hydraulic distribution system

The compact manifold and the dual differential pressureless manifold function as an interface between the heat pump, the heating distribution system, the buffer tank and, in some cases, even the hot water cylinder. A compact system is used to simplify the installation process, so that a lot of different components do not have to be installed individually. Further information can be found in the relevant installation instructions. Compact manifold The return sensor can remain in the heat pump, or should be installed in the immersion sleeve. The remaining empty space between the sensor and the immersion sleeve must be filled completely with heat transfer compound. dual differential pressureless manifold In order for the heating circuit pumps of the generator and con- sumer circuits to supply the flow to the return sensor, this must be installed in the immersion sleeve of the dual differential pressureless manifold.

7.5 Electrical connection

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-J24 to N1-J26 and terminal strip X3. If, due to a wiring error, the line voltage is mistakenly connected to these terminals, the heat pump manager will be destroyed.

7.5.2 Electrical installation

1) The supply electric cable for the output section of the heat

pump (up to 4-core) are fed from the electricity meter of the heat pump via the utility blocking contactor (if required) into the heat pump (see heat pump operating instructions for supply voltage). Connection of the mains cable to the control panel of the heat pump via terminal X1: L1/L2/L3/PE. ATTENTION!

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

2) The three-core electric supply cable for the heat pump

manager (heating controller N1) is fed into the heat pump . Connection of the control line to the control panel of the heat pump via terminal X2: L/N/PE. 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 con- tactor or be connected to the household current, as impor- tant protection functions could otherwise be lost during a utility block.

3) The utility blocking contactor (K22) with main contacts and

an auxiliary contact should be dimensioned according to the heat pump output and must be supplied by the cus- tomer. The NO contact of the utility blocking contactor is looped from terminal strip X3/G (24 V AC) to connector terminal J5/ID3. CAUTION! Extra-low voltage!

4) The contactor (K20) for the immersion heater (E10) of

mono energy systems (HG2) should be dimensioned ac- cording to the radiator output and must be supplied by the customer. It is controlled (230 V AC) by the heat pump manager via terminals X2/N and N1-J13/NO4.

5) The contactor (K21) for the flange heater (E9) in the hot

water cylinder should be dimensioned according to the ra- diator output and must be supplied by the customer. It is controlled (230 V AC) by the heat pump manager via termi- nals X2/N and N1-J16/NO 10.

6) The contactors mentioned above in points 3, 4 and 5 are

installed in the electrical distribution system. Mains cables for the installed heater must be laid and secured in accord- ance with the valid standards and regulations.

7) All installed electric cables must have permanent wiring.

8) The auxiliary circulating pump (M16) is connected to N1-

J16/NO9 and X2/N. When using pumps where the switch- ing capacity exceeds the output, a coupling relay must be interposed.

9) The domestic hot water circulating pump (M18) is con-

nected to N1-J12/NO6 and X2/N. When using pumps where the switching capacity exceeds the output, a cou- pling relay must be interposed.

10) The return sensor (R2) is integrated into heat pumps for in-

door installation. The heat pump manager is connected via the following ter- minals: X3/GND and N1-J2/U2.

11) The external sensor (R1) is connected to terminals X3/GND

12) The domestic hot water sensor (R3) is included with the

domestic hot water cylinder and is connected to terminals X3/GND and N1-J2/U3.

7.5.3 Connecting an electronically

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

It is not permitted to connect more than one electronically regulated circulating pump via a relay output.www.gdts.one 452231.66.34 · FD 9912 EN-9 SIK 6TES - SIK 14TES English 8Start-up

8.1 General Information

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 need to be checked prior to start-up: The heat pump must be fully connected, as described inChapter 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 andheating circuits must be open. The heat pump manager must be adapted to the heatingsystem in accordance with the controller’s operating in-structions. Ensure the condensate outflow functions. The outflows of the brine and heating water pressure relief valves must not be impaired.

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 performance level of the circulating pump must beadapted to the respective heating system.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 correctly ad-just the overflow valve:Close all of the heating circuits that may also be closed duringoperation so that the most unfavourable operating state - withrespect to the water flow rate - is achieved. This normallymeans the heating circuits of the rooms on the south and westsides of the building. At least one heating circuit must remainopen (e.g. bathroom).The overflow valve should be opened far enough to producethe maximum temperature spread between the heating flowand return flow listed in the table below 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 sourcetemperatureMax. temperature spreadbetween heating flow and return flow From To-5° C 0° C 10 K1° C 5° C 11 K6° C 9° C 12 K10° C 14° C 13 K15° C 20° C 14 K21° C 25° C 15 KEN-10 452231.66.34 · FD 9912 www.gdts.one English SIK 6TES - SIK 14TES 9 Maintenance and Cleaning

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 products enter the heating sys-tem via the valves, the circulating pumps and/or plastic pipes. Itis therefore essential - in particular with respect to the piping ofunderfloor heating systems - that only diffusion-proof materialsare used. ATTENTION!

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.Residue from lubricants and sealants may also contaminate theheating water.In the case of severe contamination leading to a reduction inthe performance of the liquifier in the heat pump, the systemmust be cleaned by a heating technician.Based on current information, we recommend using a 5 %phosphoric acid solution for cleaning purposes. However, ifcleaning needs to be performed more frequently, a 5 % formicacid solution should be used.In either case, 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 flow of the liquifier. It is 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 great care and all relevant regulationsof the employers’ liability insurance associations must be ad-hered 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 after-start-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 / Trouble-Shooting This heat pump is a quality product and is designed for trouble-free operation. In the event that a fault should occur, it will beindicated on the heat pump manager display. Simply consultthe Faults and Trouble-shooting page in the operating instruc-tions of the heat pump manager.If you cannot correct the fault yourself, please contact yourafter-sales service technician. ATTENTION!

Any work on the heat pump may 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 environmentally-relevant re-quirements regarding the recovery, recycling and disposal ofmaterials and components in accordance with all applicablestandards. Particular attention should be paid to the proper dis-posal of refrigerants and refrigeration oils.www.gdts.one 452231.66.34 · FD 9912 EN-11 SIK 6TES - SIK 14TES English 12 Device Information 1 Type and order code SIK 6TES SIK 8TES SIK 11TES SIK 14TES 2 Design Heat source Brine Brine Brine Brine
