1.3 Product description

ESi, EMi, and ELi ground source heat pumps are especially suited for use as theprimary source of heating for new and renovated residential buildings and holidayhomes. To ensure trouble-free operation, each heat pump undergoes configuration,testing, and a test run at the factory.

As E series heat pumps do not include a built-in storage tank, a separate storage tankis required. The size and construction of the storage tank is selected based on theapplication.

Type plate

The heat pump’s type plate is located under the heat pump’s top cover. The unit’sserial code is marked on the type plate.

This product is CE-marked.

M8010 2204EN 5 (75)

1.4 System structure and operation

Ground source heating system

Ground source heat pump system ver. 1

Principle drawing of a ground source heating system.1: brine circuit (horizontal ground loop, borehole or lake/pond system); 2: ground source heat pump;3: heating circuits (radiator heating or floor heating); 4: domestic hot water heating; 5: passive cooling(optional).

A ground source heat pump can extract thermal energy (heat) from soil, bedrock, or abody of water. Of the total energy required for heating, a heat pump collects more than75% from natural sources. Running the heat pump and the various system componentsrequires electricity, which means that the remaining 25 percent is electrical powerconsumed by the process of extracting thermal energy.

A ground source heat pump system has three main components: the brine circuit,the compressor unit (the actual heat pump), and the heating circulation. The threecirculations are isolated from each other, which means that none of the fluids used(brine, refrigerant, and water) are mixed together at any part of the process. Instead,heat is transferred between the fluids using plate heat exchangers.

Brine circuit

When the sun heats up the earth, thermal energy is stored in the soil, the bedrock,and in bodies of water. To extract this heat, the ground source heat pump circulates acold mixture of water and ethanol (brine) inside a long loop of pipe embedded in theearth (the brine circuit). As the brine passes through the brine circuit, its temperature

6 (75) M8010 2204EN

increases by a few degrees. The brine is then pumped into a heat exchanger inside theheat pump: the evaporator. In the evaporator, thermal energy is transferred from thebrine to low-pressure refrigerant, evaporating the refrigerant.

In vertical systems, a deep well is bored into the bedrock. In horizontal systems, an extensive coil ofplastic pipe (PEM 40/10) is buried to a depth of 1–1.2 meters or more or submerged in a body of water(minimum depth: 3 meters).The brine solution includes ethanol to prevent it from freezing. After being pumped through the brinecircuit, the temperature in the brine to the evaporator is approximately 0 ºC, but can be higher in thesummer and lower in the winter.

The compressor unit

From the evaporator, the refrigerant vapor is transferred into the compressor whichcompresses the vapor to a high pressure. At this stage of the process, the refrigerant’stemperature increases to over 100 ºC. After the compressor, the refrigerant is referredto as hot gas.

Hot gas is transferred from the compressor to heat exchangers (desuperheater andcondenser). Heating water from the storage tank circulates through these heatexchangers, taking thermal energy from the hot gas. As the refrigerant releases itsthermal energy, the water heats up, and the refrigerant cools down, condensing into aliquid.

The liquid refrigerant is transferred through a filter drier into the expansion valve,where the pressure of the liquid refrigerant decreases. The refrigerant is transferredinto the evaporator, and the cycle starts over from the beginning.

Desuperheater

As heat is extracted from the hot gas, its temperature decreases to a point where therefrigerant starts to condense into liquid. This point is close to the temperature requiredfor space heating (typically around 35–55 ºC). However, after the compressor, thetemperature in the hot gas is approximately 120 ºC, which means that it must first cooldown. Instead of letting the heat dissipate, it can be extracted with a desuperheater.The extracted superheat can then be used to bring pre-heated domestic hot water toits final temperature.

Note that EMi 22P and EMi 43P models have no desuperheater; instead, all thermalenergy is transferred to the heating water via the condenser.

Storage tanks, heating circuits, and domestic hot water

It is possible to connect multiple storage tanks for storing the thermalenergy produced by the heat pump. These storage tanks vary in sizeand construction.

Cool water from the bottom of the storage tank circulates through the compressorunit which heats up the water. Once heated, the water returns to the tank at a higherlevel. The water in the hot water storage tank circulates through the building’s heatingsystem, which consists of one or more heating circuits.

The heat pump features desuperheater technology which maximizes the benefits andutilization of a heat pump in overall heating. For optimal results, a storage tank with twosections separated with a baffle should be used.

The top part of the storage tank, or, the upper storage tank, is heated with superheatenergy: thermal energy extracted by the desuperheater. The desuperheater providesheating water at a very high temperature. The high-temperature layer in the tank isreserved for heating domestic hot water to its final temperature. If required, high-temperature output from the upper tank can be used in the heating system. This can beuseful especially in radiator systems.

The lower section of the storage tank, or, the lower storage tank, is used to storewarm water for the building’s central heating. The heat pump’s condenser heats up thesection to a flow temperature level required by the heating circuits. The temperature

8 (75) M8010 2204EN

in the section is regulated based on a heating curve. In normal heating conditions,the temperature in the section depends on the current need for heating (‘floatingcondensing’ operation).

Heat distribution can be arranged using water circulation (floor heating or hot waterradiators) or through air heating. The best coefficient of performance can be achievedwith floor heating, since the lower the temperature of the heat transfer, the better thecoefficient of performance.

Domestic hot water heating

Domestic hot water is heated by drawing domestic cold water through a coil or coilsinside the storage tank. In tanks with two sections, the domestic water is pre-heatedin a coil in the lower section, and brought to its final temperature in the tank’s uppersection.

Usually, domestic hot water needs to be heated to a higher temperature than the watercirculating in the heating circuits. Thanks to the two-stage heat transfer enabled bysuperheating technology, the larger lower section used for space heating can be keptat a lower temperature, since domestic hot water is heated up to its final temperature inthe smaller upper section, where the temperature is kept higher. This allows operatingtemperatures to be kept as low as possible, improving the system’s annual coefficientof performance.

E series heat pumps are well-suited for buildings with low demand for domestic hotwater. In such cases, a storage tank with only one section is used, and the heat pump’ssuperheating system is not connected.

Using existing tanks

In renovated residential buildings, the heat pump can be connected to an existingstorage tank, provided that the tank is in good condition and is suitable for usewith a ground source heat pump. The heat pump’s superheating system will not beconnected.

1.5 Optional accessories

The ÄssäCooling system

A passive cooling system can be connected to the brine circuit. The brine in the circuitpasses through an additional heat exchanger. The heat exchanger releases coolingenergy to indoor air. The heat exchanger can be a radiant cooling unit installed insidean air duct or an indoor unit (fan coil unit).

The ÄssäControl system features multiple solutions for cooling control, available asaccessories.

The ÄssäCooling product family includes both wall-mounted and ceiling mountedindoor units for cooling with the necessary installation accessories included. Passivecooling is a very economical option, since the only operating costs are associated withrunning the system’s circulation pump and fans.

M8010 2204EN 9 (75)

ÄssäSolar solar collector

ÄssäSolar is a solar collector that can be connected to almost any E series groundsource heat pump. Solar heating is an environmentally friendly supplementary energysource for space heating and domestic hot water heating. ÄssäSolar utilizes energyextracted from solar radiation, resulting in more economical and environmentallyfriendly energy production. ÄssäSolar can be used in both single-family homes andlarger buildings.

External heat sources

Several different supplementary external heat sources can be connected to the groundsource heating system, such as electric immersion heaters and electric or oil-firedboilers.

By default, the system supports control of one external supplementary heat source.Control for up to 4 external heat sources is available as an optional accessory.

M8010 2204EN 33 (75)

Heating curve ver. 1

The setpoint values correspond to heating water temperatures and can be changedby the user. Adjusted values are displayed, if the heating water temperature is beingadjusted by a function in the system, such as the Home and Away function or a timer.

Factory defaults are suitable for use with floor heating. An example of setpoint valuesused for floor heating and radiator heating are shown below.

Example of a heating curve used in floor heating (factory setting), °COutdoor temperature –20 –13 –7 0 +7 +13 +20Heating water temperature +32 +31 +29 +27 +25 +23 +21

Example of a heating curve used in radiator heating (factory setting), °COutdoor temperature –20 –13 –7 0 +7 +13 +20Heating water temperature +53 +48 +42 +36 +30 +25 +21

An example of typical value adjustments:1. If the room temperature is too cold when the outdoor temperature is −10 °C, slightly increase the flow

water setpoint at outdoor temperature points −13 °C and −7 °C.2. Wait for at least two or three days to see if the change has made a difference.3. Readjust the curve if necessary.

4.4.8 Boiler settings: storage tank settings

The boiler tank settings view allows you to adjust the temperature limits for the upperand lower section of the storage tank to match the consumption of domestic hot water.The compressor will start and stop depending on the current storage tank temperature.● Minimum value: the temperature at which the compressor starts● Maximum value: the temperature at which the compressor stops

34 (75) M8010 2204EN

Boiler settings ver. 1

There are separate setpoints for the upper and lower section of the storage tank.The first column in the view shows the setpoint values. The second column showstemperature values that have been adjusted by a function in the system, such as theHome and Away function.

Edit the setpoint values by tapping on the value. The difference between the minimumand maximum value can be 2–10 °C.

Lower tank Upper tankTemperature limits, °C

Minimum Maximum Minimum MaximumFactory settings 40 45 50 55Supplementary heating enabled   60*   60*Supplementary heating disabled   60*   85*

*Absolute maximum values.

Note that if the temperatures specified in heating circuits’ heating curves arehigher than those specified for the storage tank, the storage tank setpoints will beautomatically increased.

Operation without a desuperheaterIn E series heat pumps without a desuperheater (‘P’ models) or when thedesuperheater is not used, both sensors will be installed in the top section of thestorage tank. Use the same settings for both sensors.

Optimizing heat pump operation

To achieve the best possible coefficient of performance across the year, keepthe storage tank temperature as low as possible. As a general rule, the lower thetemperature, the better the seasonal coefficient of performance.

Backup heating

The storage tank is primarily heated with the heat pump’s compressor. If the requiredtemperature is not reached within a specified period (1–24 h, see section Othersettings), the compressor will be switched off for safety reasons. The heat pump’selectric immersion heater is used to heat up the storage tank instead. The followingalarm will be displayed: Storage tank temperature not achieved in set time.

By default, the immersion heater will be used for 12 hours.

M8010 2204EN 35 (75)

Limiting domestic hot water temperature

In the winter season, the temperature in the lower section of the storage tankis determined by the flow temperature (flow to heating circuits). As outdoor andindoor temperatures are lower, the compressor may run for long periods of time.Consequently, the water in the upper section of the tank can become scalding hot. Themaximum temperature limit for the compressor is 90 °C.

To prevent the domestic hot water from becoming dangerously hot, the system can beequipped with a temperature limiter function (optional accessory).

The maximum temperature of domestic hot water can be specified in the Hot watertemperature limiter view. Access the view through Heating curve selection, seesection Heating curves.

Domestic hot water limiter ver. 1

Adjust the limit with the plus and minus buttons next to the Maximum temperaturefield.● Adjustment range: 0–90 °C, factory setting: 55 °C.

In the summer season when no heating is required outside wet areas, the compressorruns infrequently, and less superheat is available for domestic hot water heating.Consequently, the temperature in the upper and lower section of the tank are closer toeach other.

4.7 Cooling (optional)

The ground source heating system can be equipped with optional cooling solutions.There are two primary types of cooling available: free cooling and flexible cooling.

Basic cooling options can be accessed through the Other settings menu (menu button→Other settings →Cooling). Advanced cooling options can be accessed through theMaintenance menu (menu button → Maintenance menu → Cooling).

M8010 2204EN 41 (75)

4.7.1 Free cooling

An independently operating cooling system can be connected to the heat pump’s brinecircuit.

A circulation pump draws cool brine from the brine circuit and pumps it through acooling circuit. As the brine passes through the circuit, heat is extracted from indoor air.After the cooling circuit, the brine is fed back into the brine circuit.

If the system includes an optional room temperature sensor, the system willautomatically adjust room temperature to the desired level. If there is no roomtemperature sensor, the system will always run at full capacity.

Free cooling is an energy-efficient and economical method for cooling spaces, sinceelectricity is required only for running the circulation pump and cooling unit fans.

There are three operating modes for free cooling: Room temperature control, Externalcontrol, and Manual control. The control mode is determined during commissioning inthe Maintenance menu.

Room temperature control

The Cooling - Targets temperature view allows you to specify the indoor temperaturerange within which the cooling system will be operational.● Set the minimum and maximum value by tapping each value’s field.

Cooling - targets temperature ver. 1

Additionally, the view shows the current room temperature, the current brinetemperature (Liquid), air moisture level, and dew point. The current operating mode(State) is also shown.

External control

In the External control mode, the cooling system will be controlled by an externalthermostat. This thermostat needs to be installed and adjusted by the installationcompany as specified in the wiring diagrams supplied with the unit.

42 (75) M8010 2204EN

Manual control

Cooling - Manual ver. 1

In normal operation, the system will keep the temperature in the brine used for coolingone degree above the dew point. The purpose of this function is to prevent condensatefrom accumulating in any cooling units connected.● To disable this function, check the Manual checkbox and enter a specific brine

4.7.2 Flexible cooling

Flexible cooling is a versatile solution with a multitude of options for efficient andeffective cooling. The solution has six different operating modes, each describedbelow.

Flexible cooling ver. 1

Delay refers to the delay after which the system switches from passive cooling toactive cooling. Targets temperature typically refers to room temperature, but can alsorefer to an industrial or agricultural process, such as manure slurry channel cooling.

Heating

The ground source heat pump provides heating by transferring thermal energy from thebrine circuit to the storage tank for use in space heating or domestic hot water heating.

Heating and cooling

The ground source heat pump heats up the storage tank by transferring thermal energyfrom a brine circuit and a cooling circuit to a storage tank. This mode is in use whenheating and cooling is required at the same time.

M8010 2204EN 43 (75)

Passive cooling

The cooling circuit is cooled down by transferring thermal energy to the brine circuit(see section Free cooling). If the cooling circuit temperature does not fall down to itssetpoint within a predetermined period (Delay), the system switches over to Activecooling.

Active cooling

The ground source heat pump uses the compressor to extract heat from the coolingcircuit and transfer the heat into a storage tank.

Excess heat transmission

If storage tank temperature rises too high during active cooling, heat exchangersare used to transmit the excess heat to the brine circuit or evaporate the heat to theatmosphere.

OFF

Cooling is not used.

Cooling control

Cooling control is based on operating modes as well as solenoid valve and circulationpump control. Solenoid valve positions for each operating mode must be set in theMaintenance menu.

In the Maintenance menu, you can set the control mode to Room temperature orExternal. These modes function in the same way as in Free cooling.

5 Maintenance

5.1 Maintenance and care

Oilon and Lämpöässä heat pumps are highly reliable and easy to maintain. If thesystem has been installed with care and in accordance with the instructions provided,there is usually no need for maintenance.

It is recommended to check the following at least once a year:● Fluid level in the filling bottle (if installed in the system's brine circuit). Check

monthly in the first year.

Filling bottle ver. 1

● Brine circuit pressure (if a pressurized brine circuit is used). Guideline value: 1 bar.● Brine circuit T strainer.

● For instructions, refer to section Filling and bleeding the brine circuit.

Annual inspection

According to rules and regulations by authorities, appliances with a refrigerant chargegreater than 6 kg must undergo annual leakage testing. Heat pumps with a 3–6 kgrefrigerant charge are hermetically sealed, and do not require annual inspection.

A periodic inspection service is available for our heat pumps. During each inspection,the heat pump’s operation is checked step by step. Any observations will be recordedin an inspection report and the necessary corrective measures (such as adjustments tosettings) will be taken. For more information about the service, contact your dealer.

5.2 Typical problems during operation

The heat pump is not receivingpower.

Check that the control current andthe main switch are on.

Blown or tripped fuse. Check the building’s orapartment’s main fuse and theheat pump’s supply fuse.

No text on the screen.

Broken screen, or a disconnectedor broken screen cable.

Contact a repair service.

In new buildings, a sudden dropin outdoor temperature maycause the heating capacity to beinsufficient for a short while. Thisis due to the fact that the moisturein a building's structures absorbs alot of heat when it evaporates.The system does not produce

enough heat.During the first year, the heatpump may not be able toextract heat from the groundat full capacity, since the soilsurrounding the brine circuit hasn'tyet compacted enough.

No action required.

An active corrective function thatadjusts the original setpoint (suchas the at home/away function) isactive.

If required, disable the function.

A voltage spike caused bylightning has damaged the heatpump's controller, causing thetemperature values to drop fromactual values.*

Replace the controller.In the Measurements screen, thesetpoint and the measured valuedo not match.

The brine circuit pump isin manual operation, and,consequently, the controllercannot adjust its speed.

Return the pump’s control mode toautomatic.

46 (75) M8010 2204EN

Problem Cause SolutionIn summer, the flow temperaturesensor reading is higher than thevalue provided by the heatingcurve. This is caused by atemperature increase in theheating circuit.

No action required.

The demand for heating is highdue to, for example, a very lowoutdoor temperature or, during thefirst year, heat required for dryingout the building’s structures.

No action required.

The compressor starts frequentlyor stays on for long periods oftime. Insufficient refrigerant charge. Check whether there are bubbles

in the sight glass even aftersome minutes of use. Contact arefrigeration or appliance service.

52 (75) M8010 2204EN

Setting Description ExampleInverse control Changes the control direction of

the control valveOFF position: when the voltage is 0 V, thecontrol valve is all the way in the right position.ON position: when the voltage is 0 V, thecontrol valve is all the way in the left position.

Band(10–600 °C)

The deviation from targettemperature at which the valveis adjusted from one extremeposition to another.

● Factory setting for heatingcircuits: 300 °C

● Factory setting for DHWtemperature limiter: 30 °C.

If the band is 140 °C and the target temperaturedeviates from the current temperature by14 °C, the valve will be adjusted to 10% of itsmaximum.

● If the temperature changes too rapidly,increase the band.

● If the temperature changes too slowly,decrease the band.

Integration time(5–300 s)

Interval for checking andcorrecting temperature difference.

● Factory setting for heatingcircuits: 50 s.

● Factory setting for DHWlimitation: 40 s.

If the integration time is 10 s, valve position willbe adjusted every 10 s (if necessary).

Derivation time(0–10 s)

Reaction rate for correcting thetemperature difference.Factory setting: 0

The greater the derivation time, the more thecontrol valve’s position will change with eachadjustment.Note that increasing the derivation time mayincrease fluctuation.

Voltage(0–10 V)

The minimum and maximumvalues for the control valve’scontrol voltage signal. Factorysettings: 0.0–10.0 V AC

The setting depends on the regulator beingused.

Temperaturedifferential(0–10 °C)

The maximum allowed differencebetween current temperature andtarget temperature.Factory setting: 0 °C.

If set to 5 °C, the valve’s position will be changedonly when the difference between the measuredtemperature and the target temperature isgreater than 5 °C.
