100% GEOTHERMAL HEAT
2.1. Lämpöässä structure and operating principle
The Lämpöässä ESi/EMi/ELi series are especially suitable for use as the
primary heating system of new and renovated residential buildings and
secondary residences. In order to ensure trouble-free operation, all
Lämpöässä geothermal heat pumps have been test-run, set up and
tested by the manufacturer. If a geothermal heat pump is being used in
the part-power conguration, for example, because high temperature is
required in the radiator system, the heating system must be dimensioned
and adjusted so that the return water temperature is always below +55
°C. By part-power we hereby mean that the electric heating element
(immersion heater) is allowed to switch on if necessary.
Because Lämpöässä ESi/EMi/ELi series doesn’t include integrated storage tank, it needs a separate storage tank to function. The size and
structure of the storage tank can be chosen due to the need for hot
domestic water. For the operating principle and main components of Esi/
Emi series, see the picture on page 6. The picture has also been discussed in Sections 2.1.1-2.1.3.
2.1.1. Heat collection circuit
The geothermal heat system circulates water/ethanol mixture protected
against freezing in the heat collection circuit in order to collect thermal
energy accumulated in soil through solar radiation. The heat collection
piping used comprises a bore hole or plastic pipe (PEM 40/10) placed at
least 1-1.2 metres deep in soil or at least 3 metres deep in water. The
circulating mixture warms up by a few degrees and delivers this thermal
energy to the geothermal heat pump’s EVAPORATOR (1), i.e., the heat
exchanger. The temperature of the heat collection uid arriving from the
soil to the evaporator is approx. 0 ºC.* This temperature can be lower in
winter and higher in summer. At the evaporator, the energy of the heat
collection uid is transferred to the low-pressure refrigerant circulating
inside the heat pump. The refrigerant is evaporated using the thermal
energy.
2.1.2. Compressor unit
From the evaporator, refrigerant vapour is transferred to COMPRESSOR
(2) for ramping up the pressure. This is accompanied by steep temperature rise. In the course of the heat pump process, the refrigerant temperature is the highest after the compressor, in excess of 100 ºC, and the
refrigerant is referred to as ’hot gas’.
1. Safety
In order to ensure trouble-free operation of the Lämpöässä geothermal
heating system and achieve the best efciency, the system must be
transported and installed in accordance with the manufacturer ’s instructions. After performance of installation works, the installation checklist
must be reviewed in order to minimise the risk of potential errors. The
manufacturer shall not accept any responsibility for equipment defects or
related expenses caused through installation faults.
The pipe and electrical installations for the Lämpöässä geothermal heating systems can only be installed by qualied persons. If problems
should occur during installation, we recommend that you contact your
dealer or consult with Lämpöässä maintenance specialists by phone.
If the fault symbol is displayed on the touch screen, a system
malfunction has occurred. Press this button to display information on the cause of the malfunction.
Press this button for additional information on the touch
screen data.
2. Geothermal heating system operation
A geothermal (or ground source) heat pump can extract geothermal heat
from soil, water bodies or a bore hole. For an overview of the heat pump
and its operating environment, see the picture below. Of the total thermal
energy required for heating, Lämpöässä collects more than 75% from
natural sources. For thermal energy collection, approx. 25% of electrical
energy is required for running the various system components.
The geothermal heating system consists of heat collection piping, water/
ethanol (ethyl alcohol) mixture circulating within the piping, and a
ground source heat pump unit. The ground source heat pump unit comprises an integrated hot water storage tank, compressor, heat exchangers, and closed refrigerant circuit, i.e., compressor unit. The heat collection uid in the ground circuit, the refrigerant and the water in the
heating network never mix at any stage of the process. Heat is transferred
between uids using plate heat exchangers.

USER MANUAL
100% GEOTHERMAL HEAT
The hot refrigerant is transferred from the compressor to heat exchangers
(condenser and superheater), through which it releases its thermal
energy into the heating water storage tank (6). The heat in the storage
tank is used for heating and hot domestic water production purposes.
When heat is extracted from the refrigerant vapour, a point is reached
where the vapour begins to revert into liquid – i.e., is condensed. This
point is close to temperature required for heating (in general, approx.
35-55 ºC). Since the refrigerant gas leaves the compressor at approx.
120 ºC, it cools rst and liquees later. The energy released in the course
of such cooling is referred to as superheating energy. The superheating
energy can be efciently utilised in nal heating of domestic water, by
using a superheat exchanger (3).
After the superheater, the refrigerant is transferred to CONDENSER (4),
where it is transformed from vapour to liquid, releasing the heat to the
heating water storage tank and from there to the heating network. Emi
22P- and Emi 43P -models with separate storage tank has no separate
superheater heat exchanger. All thermal energy is conceded through
condenser heat exchanger to the separate storage tank. Having conceded
its thermal energy, the liquid refrigerant is transferred through dehydration lter to EXPANSION VALVE (5), where the pressure of the liquid
refrigerant drops and a new cycle from the evaporator can commence.
2.1.3. Hot water storage tank
It is possible to connect multiple storage tanks to ESi/EMi/ELi -models to
store the thermal energy created. These storage tanks can vary in size.
Lämpöässä Esi and Emi utilises carefully designed superheating technology allowing advantageous generation of heating and domestic hot
water. The objective is to maximise the share of geothermal heat in overall heating. A two-sectioned HEATING WATER STORAGE TANK (6)
equipped with partition enhances utilisation of superheating energy. The
coefcient of performance remains at a high level, since the energy-efcient superheating mixture involves heat transfer between two tank sections using two different heat exchangers (condenser and superheater).
Water from the hot water storage tank is circulated in the heat distribution piping consisting of 1-3 loops.
The top part of the storage tank, i.e. the UPPER STORAGE TANK (6a),
is heated by using superheat removal heat exchanger (superheater 3) by
the extremely high thermal energy acquired from the compressor. Hot
superheating energy is stored for nal heating of domestic hot water. If
required, the high thermal energy can also be transferred to the heating
system from the top storage tank.
The LOWER STORAGE TANK (6b) stores the thermal energy required for
central heating from the condenser (4) at heating network-adjusted tem-

peratures lower than those of domestic hot water. The storage tank
temperature levels are controlled by an adjustment curve – thus, at ordinary heating circumstances, the temperature varies depending on the
heating need. In such cases, the system operates in so-called ‘oating
condensing’ mode. Heat distribution can be arranged using water circulation-based oor heating, hot water radiators or air heating. The best
coefcient of performance is achieved by oor heating, since the lower is
the temperature of heat release, the better is the coefcient.
Domestic water is heated within a COIL (7) inside the storage tank,
which is divided into two parts. The domestic water is pre-heated in the
coil located at the storage tank’s lower part, while nal heating takes
place inside the coil located at the tank’s upper part. In general, domestic water temperature must exceed that of the heating water. Owing to
the two-stage heat release of the superheating technology, the larger
storage tank section heating the supply water can be kept at a lower
temperature, since nal heating of the domestic water takes place using
the upper storage tank section of higher temperature. In such a case, the

process operation temperatures remain as low as possible, which
improves the system’s annual efciency. Division of the coil into two
parts allows heating of the domestic water circulation only using the
upper storage tank coil, so that blending of the storage tank temperature
stratications is avoided.
Lämpöässä ESi/EMi/ELi are well suitable for pieces of real estate with
especially high hot domestic water consumption. In renovated residential
buildings Lämpöässä Esi/Emi can be connected to existing separate storage tank as well if the storage tank is in good condition and is suitable
for geothermal heating. In this case Lämpöässä ESi/EMi/ELi can be connected without the superheating feature and separate storage tank is
used. In case the building includes previously installed water tank that is
suitable for geothermal heating, it can be connected to Lämpöässä ESi/
EMi/ELi.
2.2. ÄssäCooling cooling system
A passive cooling system can be installed into the heat collection circuit,
in which case the uid in the circuit is circulated through an additional
heat exchanger. The heat exchanger releases cooling energy to indoor air.
Such exchangers include radiant cooling units provided within the ventilation system or fan coils installed indoor. Lämpöässä offers multiple
solutions for control of the cooling with ÄssäControl control system.
These are available as accessories.
The Lämpöässä product family includes wall and ceiling-mounted fan
units for cooling, complete with installation set. Passive cooling is a
favourable approach to cooling, since the only running costs are associated with water circulation pump and cooling fan operation. In Esi/Emi
series cooling is connected externally to the device through heat collection circulation.
3. How to use the equipment
3.1. Control system functioning
ÄssäControl by Lämpöässä is a logic-based control system. It considers
the conditions prevailing in the premises and the surrounding environment with improved precision. ÄssäControl control system adjusts the
heating network supply water temperature proceeding from the storage
tank and outdoor temperature based on a seven-point adjustment curve,
so that the room temperature remains pleasantly even regardless of outdoor temperature variations.
Depending on the connections, the control system controls 1-3 heat
distribution circuits or 1-2 heat distribution circuits and domestic hot
water temperature. With the help of the ÄssäControl control system, it is
also possible to control a heat source external to the geothermal heat
pump unit.
These instructions contain a user manual and a manual for equipment
installer. Maintenance functions are password-protected.
3.2. Touch screen functioning
After unit start-up the display goes into basic mode, displaying on the
two-part ÄssäControl home screen function shortcuts (8 pc.), time, date,
and outdoor temperature. To switch between the two home screens, use
the arrow buttons in the bottom right corner. To access the Functions

3.4.4. Home/Away function
The home/away function shortcut can be used to save energy when the
residents are away for a long holiday trip, for example. The function
Away changes the heat distribution circuit and storage tank temperature
settings until the set date and time; after that, the original set values are
automatically restored (i.e., the normal mode Home is reactivated).
The system’s normal mode is Home. To activate the Away function, press
the button Away and set the date and time of your return for restoring the
mode Home (default value: 24 h). The changes in room and storage tank
temperatures can also be programmed. In order to ensure restoring of the
normal temperatures by the time of your return from the holiday trip, the
day preceding the actual return date, for example, could be programmed
as the return date.
Set the desired heat distribution circuit temperature adjustment under
Room temperature adjustment; values between -10...+10 °C are possible. Set the desired storage tank temperature adjustment value under
Storage tank temperature adjustment. This setting inuences domestic
water temperature. Values between -10...+10 °C are possible. If any of
these temperatures is not to be changed, keep 0 °C as its value. When
leaving for a holiday trip, for example, both of the values might be lowered by approx. 5 degrees by setting -5 °C as the room/storage temperature adjustment value.

3.5.1. Storage tank settings
Storage tank set values are used to adjust the storage tank top and bottom section temperature limits to meet the site’s domestic hot water
consumption. The system includes a function that automatically elevates
storage tank temperature if the heat distribution circuit adjustment curves
are set higher than the storage tank temperature. Factory settings for the
storage tank bottom section are 40 °C (min) and 45 °C (max). Factory
settings for the storage tank top section are 50 °C (min) and 55 °C (max).
The difference between Min and Max values can be 2...10 °C. The maximum allowed storage tank top and bottom section temperature set value
is 60 °C in case of full power geothermal heat pumps and 60 °C (bottom
section) / 85 °C (top section) in case of part-power geothermal heat
pumps. In Esi, Emi 22P-Emi 43P or ELi 60P-90P model with separate
storage tank are the temperature sensors installed in the same water
space on the top section of the storage tank. In such case same temperature settings are used for the top and lower sections of the storage tank.
The value Correction indicates the temperature as corrected by the Timer
function, Home/Away function, Domestic water boost function, or automatic heat distribution circuit correction.
The storage tank temperature is a decisive factor in compressor starting
and stopping. The minimum value programs compressor starting at the
storage tank’s target temperature. The maximum value programs compressor stopping at the storage tank’s target temperature.
The storage tank is heated by the compressor. If the target temperature
cannot be reached in a certain time (1...24 h), it is presumed that there
is something wrong with the compressor and the compressor is turned
off. In such cases, the storage tank is heated by the electric heating element. The default set value for this function is 12 h. If the electric heating element is switched on, the following warning is displayed on the

control panel display: Storage tank temperature not achieved in set time.
Electric heating element has been switched on. For more information on
programming the time, see menu Set values. NOTE! Electric heating is
used only as back-up!
Maximum annual ground source heat pump efciency can be achieved if
the storage tank temperature is kept at an optimal level. The ground rule
is that the storage tank set values must be kept at the lowest possible
level, since it allows the best annual efciency.
In winter, when the need for heating is larger, the set value for the storage
tank bottom section should be programmed in relation to the supply
water temperature. The temperature of the storage tank upper part
increases after a long period of use and the threshold value for the compressor to run is 90 °C. This is due to the superheating properties of the
storage tank structure. Because of this, the domestic hot water temperature limiting function (option) can be used in order to avoid potential hot
water-related hazards. In general, the compressor is controlled according
to the minimum setting of the storage tank lower part.
In summer, when there is no need for heating (with the exception of
humid rooms), the compressor is seldom on and there is less superheating for domestic hot water production. In such a case the storage tank
upper part and lower part temperatures are close to each other.
3.5.2. Heating curves
Heat distribution circuits (HD) are controlled by a seven-point adjustment curve. Depending on the connections, the control system controls
1-3 heat distribution circuits or 1-2 heat distribution circuits and domestic hot water temperature. In the Heating curves menu, the values of all
heat distribution circuits can be changed separately to meet the heating
water temperature (supply water) at a certain outdoor temperature.
Exemplary oor heating adjustment curve (factory setting) °C*
Outdoor temperature -20 -13 -7 0 +7 +13 +20
Heating water temperature +32 +31 +29 +27 +25 +23 +21
Exemplary radiator heating adjustment curve °C*
Outdoor temperature -20 -13 -7 0 +7 +13 +20
Heating water temperature +53 +48 +42 +36 +30 +25 +21
The factory-set heating curve is suitable for oor heating. The adjustment curve values should be specied during the rst year; they could be
changed as follows, for example: If the indoor temperature feels too chilly
while the outdoor temperature is -10 °C, the supply water set value can
be increased a little at the outdoor temperature points -13 °C and -7 °C.
Monitor the inuence of the adjustment on room temperature for at least
24 hours before making any further modications in adjustment curve
set values. When using radiator heating temperature change is quicker.
For the temperature correction caused by Home/Away or Timer functions, see the bottommost line.
Maximum domestic water temperature can be limited by adjusting the Domestic water temperature limit value between 0...90 °C (factory setting: 55 °C).

3.5.3.9. ÄssäControl-cooling, free (accessory)
To the heat pump collector can be installed a cooling system, where the
heat transfer uid is circulated in the building. If the system is tted
with a room temperature sensor, cooling circuit temperature is automatically adjusted to the desired room temperature. Without the room sensor,
the system is cooling at maximum power. Free cooling is an energy-efcient way to cool the property, as the operating cost only consists of a
circulating pump and energy consumption of the cooling fan motor. The
cooling setting values can be modied under Other settings and Cooling
(Note! The cooling-function is acquired).When taking the cooling system
into use, the cooling control mode is set in the service menu. In the
service there is following selectable control modes: Room temperature,
External and Manual.
Room temperature
Room Temperature menu provides the cooling temperatures, which determines when the cooling system is running. In addition, the menu will
display the current room temperature, coolant temperature, humidity, and
dew point value, as well as system status heating / cooling / off).
External
When the control mode is External, cooling is controlled by an external
thermostat, which is connected according to the wiring diagram.
Manual control
When the control mode is set to Manual, this menu can be used to
switch to active cooling. The system tries to keep the coolant temperature at a minimum of one degree above the dew point. From the menu
coolant temperature can be set to be constant, where the dew point
effect is not taken into account.
3.5.3.10. ÄssäControl-cooling, exible (accessory)
Flexible cooling allows for a more versatile and more efcient cooling. In
the exible cooling, there are six different control modes:
1. Heating
Ground source heat pump uses the ground loop by transferring
energy to the storage tank for heating or hot water.
2. Heating and cooling
Ground source heat pump heats the boiler by transferring heat
from the refrigerant circuit and ground loop to the storage tank.
This function is available when heating and cooling is needed
simultaneously.
3. Passive cooling
Ground source heat pump cools the cooling circuit by transferring
heat to the ground loop. If the coolant circuit temperature has not
reached the set value, in the time available (the display section
Delay), becomes passive cooling automatically active cooling

5. Unloading the extra heat
If the temperature in the accumulator rises to high, the extra
heat is unloaded via an exchanger to the ground loop or air.
6. Switched off
The control of cooling is based on the machine’s control modes, and
control of magnetic valves and the circulating pumps. The position of the
magnetic valves in different modes are determined in the service menu.
In the service menu there is available control mode Control of the room
temperature and External, which acts as free cooling.
3.5.3.11. Linkin several ground source heat pumps
Determing the master device
If the system contains more than one geothermal heat pump, one has to
be chosen as master device. All the sensors are connected to the master
device. Program settings are dened in the factory and the master device
is marked with the MASTER-marking and other devices with SLAVEmarking. All heat pumps can be monitored and controlled from each
heat pumps control screen.
The compressors rotation extra accessory can be enabled when the system contains more than one geothermal heat pump. However, all the
linked ground source heat pumps have to be equipped with ÄssäControl
Compressor rotation
If multiple ground source heat pumps are used in the building, they can
be connected to each other with compressor rotation (optional equipment). In such cases should be noted that all connected ground source
heat pumps are equipped with ÄssäControl control system. Compressor
rotation evens the operating hours of compressors. In the Compressor
rotation menu can the start and shutdown intervals be modied. Possible
values are for start interval values between 1...240 min (factory setting
1 min) and shutdown interval 1...240 s (factory setting 10 s).
3.5.4. Measurements
Ground source heat pump operation can be monitored using various different measurement data. Use the screen numbering in the bottom bar
for navigating between the Measurements screens.
Measurements screen values describe heat pump operation under various conditions and the values shown cannot be modied. The left-hand
column indicates current measurement values and the right-hand column the respective set values. Measurement results from all sensors,
compressor running times, and electric heating element operation times
can be browsed.

INSTALLATION
4. INSTALLATION WORKS
4.1. Before installation
Pipe assemblies for the installation of the Lämpöässä system may only
be installed by qualied and trained persons. The equipment must be
installed in compliance with instructions provided; after performance of
installation works, the installation checklist must be reviewed in order to
minimise potential errors. The manufacturer shall not be responsible for
any equipment defects or related expenses caused through installation
faults.
Check that:
• all the necessary hoses and sensors have been delivered
• the ground source heat pump has been correctly tted
• the connections on top of the geothermal heat pump are intact
• the fuse size is correct for the master fuse and the ground source
heat pump (see technical specications)
• the ground circuit collection piping and supply piping have been
installed properly
4.1.1. Transport
The Lämpöässä geothermal heat pump must always be transported in a
vertical position. If tilting the equipment is unavoidable, for example, to
pass through a doorway, the maximum tilting angle allowed is 45°. In
other cases, the machine’s compressor unit must be detached during
tilting. The equipment may be moved from beneath using a fork lift, for
example. Do not go underneath the equipment while it is being lifted!
A transportation platform has been fastened on both sides of the ground source
heat pump using screws. The ground
source heat pump’s accessory package
includes adjustable feet to be screwed into
the unit bottom (see picture). After that,
remove the wooden platform elements and
their xation screws (4 pc). To remove the
platform, lift the equipment by a fork lift,
for example.
4.1.2. Ground source heat pump installation area
We recommend that the Lämpöässä ground source heat pump be
installed in a warm room with oor drain. During installation, when lling
the ground circuit, some water/ethanol or water/glycol mixture may be
splashed onto the oor. The chosen area does not have to be reproof.
Approx. 50 cm of installation space should be reserved above the
equipment.
The oor must be able to withstand the weight of the ground source heat
pump carrying a full storage tank. The oor must also be sufciently
even, because the ground source heat pump must be installed as level as
possible. Final adjustments can be made using the adjustable feet underneath the equipment.
4.1.3. Removing the packaging
Remove the plastic wrapping and corner padding from around the product. Check that the pump has not suffered any transportation damage. If
the heat pump is found to be damaged, the transport company must be
immediately notied. We recommend photographing the damages.
Also check the contents of the delivery immediately. The Lämpöässä ESi/
EMi/ELi-series accessory package includes the following components:
• valve motor
• 4-way valve (GSHP with separate storage tank with intermediate
oor) OR 3-way valve (GSHP with separate storage tank)
• heat distribution pump
• outdoor sensor
• heating circuit temp. sensor
• storage tank temp. sensor
(2 pc.)
• adjustable foot (4 pc.)
• lling group
• lling bottle (packaged
inside the product)
• safety valve
If some of the accessories specied
in the order are not included in the
delivery, notify the equipment
dealer within ve days.
The plastic roof of the product is
removed by lifting it from the edges.

100% GEOTHERMAL HEAT
The front door is opened by sliding it upwards. Before this two screws in
the front panel must be removed (as shown in the picture on right).
4.1.4. Space requirements
Lämpöässä ESi/EMi/ELi series ground source heat pump can conveniently
be placed into a technical or utility room. The oor space to be reserved
between the machine and storage tank must be adequate for pipe connections. Considering possible equipment maintenance, there must be
approx. 70 cm of free space in front of the geothermal heat pump.
The height of a Lämpöässä ESi/EMi/ELi series ground source heat pump
(including adjustable feet) is at least 145 cm. The transport platform
adds some 8 cm. At the back section of the machine are the ground
circuit connections that rise some 5 cm above the roof. Approx. 50 cm
of free space must be reserved for connections on top of the machine.
This should be kept in mind when installing the equipment into a low
room, such as basement.

4.2.2. Filling and de-aeration of the heat collection circuit
Accessories required for the lling and de-aeration of the ground circuit:
• mixing tank, 60 litres
• submersible pump tted with a lter, lifting height approx. 30m
• water/ethanol or water/glycol mixture (1:1) with a frost resistance of -16 °C
• reinforced hose 1” (2 pc.), length approx. 3 m
• connector 1” (1 pc.) (female)
• connector 3/4” (1 pc.) (female)
WORK STAGES
Please check that the ground circuit has been correctly connected.
NOTE! The following instructions are for ESi series. The lling and de-
airing is done similarly to EMi/ELi series but the valve gropup is built
during installation.
1. Remove the styrox packaging
protecting the group of ll
valves.
2. Detach the expansion vessel
from the foremost ball valve.
3. The foremost shut-off valve
(2) of the group of ll valves
must always be open.
4. Attach the submersible pump reinforced hose to the foremost ball
valve (3) in the group of ll valves and open the ball valve.
5. Attach a reinforced hose from the ball valve (4) at the back of the
group of ll valves to the ll container and open the valve.
NOTE! The ow direction has to be correct since there is a one
way valve installed between the cooling connections.
6. Fill the container with water/ethanol or water/glycol (frost r. -16
°C) mixture (ratio 1:1).
7. Bleed air from ll hoses by activating the submersible pump and
keeping the valve (1) open. When air has escaped, close the valve
(1) to start actual uid circulation through the ground circuit.
8. Add uid until the piping is full. Upon de-aeration, the unit’s own
brine circulation pump can be used to speed up uid circulation.
• Check that the motor protection switch (QM1) is not on.
• Turn master switch (Q1) and control current switch (F10) on.
• The forced control of gound circuit pump can be activated
from the maintenance manual of ÄssäControl. Go to manual
control and choose manual control on and ground circuit 1 on.
• Turn the motor protection switch (QM1) on.
NOTE! When using the system’s own brine circulation pump for

de-aeration purposes, check that the ow direction of the separate
submersible pump is always the same as that of the unit’s pump.
9. Keep the submersible pump running until the uid is clear and no
gurgling can be heard from the pipes. NOTE! De-aeration usually
takes several hours and helps to ensure that all the air is remove
from the system and will not cause any malfunctions once the
system is started. Leave no pressure in the network! Remove any
air from the evaporator through the de-aeration connection of the
pipe located between the ground circuit and the evaporator.
10. When de-aeration has been completed turn the motor protection
switch QM1 off and also manual control function off.
11. Open shut-off valve (1) at the back of the group of ll valves.
12. Close both ball valves (3) and (4).
13. Remove the ll hoses.
14. Fasten the expansion vessel back in its place in the foremost ball
valve (3) in the group of ll valves.
15. Remove the safety valve on the expansion vessel.
16. Fill ¾ of the expansion vessel with water/ethanol or water/glycol
mixture.
17. Fasten the safety valve to the expansion vessel.
18. Open the foremost shut-off valve (3) in the group of ll valves.
19. Remove and clean the net strainer (5) on the mud separator,
repeat this several times, if necessary. The red-handled valves (1)
and (2), as well as the valve under the ll container must be
closed in order to prevent uids from running out.
Filling and de-aeration have now been completed.
4.2.3. Connections between heat pump and storage tank
The storage tank is connected to the ground source heat pump pursuant
to the connection diagram at the end of this manual. The connections for
the ground source heat pump are shown in the picture found in chapter
4.2.1. The factory setting for super heat valve can be found in the
technical specications table. The setting can be adjusted in the maintenance menu.
4.2.4. Heating and domestic hot water connections
Connect the heating and domestic hot water connections pursuant to
connection diagrams in the chapter 8. Connection diagrams.
Page 21

100% GEOTHERMAL HEAT
Heating connection
Heat distribution circuit surface sensors located on top of the storage
tank must be installed to the distance of approx. 0.5 m from the threeway or four-way valve. Circuit HD1 is always the main heating circuit
(rooms, for example); it is used for higher temperature (radiator heating,
for example). In case of compressor malfunction, the electric heating
element heats the circuit HD1 more efciently. Circuit HD2 is used in
radiator-heated buildings for the possible oor heating share or for other
purposes (e.g., humid rooms). In these cases the circuits can be controlled individually. The heat distribution circuits can be unconnected
through Summer Fuctions for summer. In this case e.g. HD2 in humid
rooms can only be used.
The pipes in the heating network are connected to the ground source
heat pump using either textile hoses (network of radiators) or using a
xed piping network (oor heating). These connections prevent sound
from passing into the network. All heating connections (for example, a
heating radiator for an air conditioner or a heated towel rail) must be
made to the heat distribution circuits, not domestic hot water. When the
network piping is in place, lling may commence.
NOTE! Maximum storage tank pressure is 1.5 bar!
NOTE! If renovating, ensure that the heat distribution piping has been
properly rinsed before connecting the geothermal heat pump. If renovating, installing a mud separator to the heat ditribution circuit is
recommended.
Speed controlling of the heat circulation pumps of Esi series
Heat circulation pumps with EMi/ELi-series determined by demand of the
heatable estate. Heat circulation pumps will be adjusted according to
manufacturer’s instructions.
Grundfos UPM3 AUTO heat circulation pump which is used in a HD
circuit can be set in three different controlling modes: proportional
pressure mode, constant pressure mode, constant curve mode. Factory
setting is proportional pressure mode 3. In radiator network constant

Storage tank and heating system lling and de-aeration
The storage tank is to be lled with special care through the group of ll
valves included in the system so that the storage tank pressure never
exceeds 1.5 bar. While lling the storage tank, the air inside it must be
allowed to escape freely and not through air valve or safety valve, for
example. Suomen Lämpöpumpputekniikka Oy cannot be held responsible for any expenses resulting from storage tank breakage in situations
where the tank has not been lled with water pursuant to the above
instructions.
There must be a de-aeration valve in the same branch with the group of
ll valves. The expansion vessel may be in the same branch as well. The
pipes in the network are lled with water.
Page 22

100% GEOTHERMAL HEAT
INSTALLATION
Filling and de-aerating a heating system tted with a pressure gauge:
• Open the ll valve on the heating network.
• Fill the network with water.
• De-aerate the storage tank and network until all the air has been
removed and leave the pressure at 1-1.2 bar (max. 1.5 bar).
• Maximum pressures:
• Heating network storage tank – 1.5 bar
• Domestic hot water circuit – 9 bar
Domestic hot water connections and circulation of water
If there is no domestic hot water circulation at the site, make connections
pursuant to HVAC diagrams annexed to these instructions. Domestic
water is connected to the ground source heat pump pursuant to the
picture in Section 4.2.1. The same picture is provided on top of the unit,
under the roof. The mixing valve is tted to the hot water pipe in order to
prevent burns. The overow pipe is joined to the oor drain as instructed
or to an overow funnel if the distance to the oor drain is more than two
metres. The overow funnel must be directed down towards the oor
drain. The backpressure valve is tted to the cold water joint on the input
side (see the annexed HVAC connections diagram).
NOTE! External radiators or dryers may not be connected to domestic hot
water circulation!
If the heatloss of the DHW circuit is considerd great it is recommended
to install an ÄssäStream heater (see more in the ÄssäStream brochure).
HVAC checklist
Check that
• the joints are tight and there are no leaking valves
• the expansion vessel on the heating system and ll side is prop-
erly installed
• the overow pipe on the safety valve and the pressure gauge on
the heating system have been properly installed
• the heating system has been lled and de-aerated appropriately
• the ground circuit has been installed, lled and de-aerated

The Lämpöässä heat pump is connected to a 400 V (50 Hz) electrical
network. The Lämpöässä heat pump has been tted with an integrated
electrical switchboard which is permanently powered. The location of
the protection switch for the motor and other tripping devices are in the
electrical switchboard that is inside the heat pump. The electrical
switchboard is located at the top of the heat pump, under the plastic
roof. The plastic roof of the product is removed by lifting it from the
edges. A plastic-coated wire is used as a supply line, which wire travels
to the master switch in a casing pipe. The electrical switchboard cover
can be removed by undoing four screws on top of the switchboard.
While using the superheat function in Esi-model the connection plug
(XP11) of superheat circuit pump (P11) needs to be mounted to the
connection box. The connection box can be found from behind of the
heat pump front plate. More details can be found from the annexed
electrical connections diagram.
In the electrical connection of heat distribution pump (P12/P13) must be
used plug-ins included in the package. See the annexed electrical connections diagram.
4.3.1. Outdoor sensor
In order for the outdoor sensor to recognise weather conditions as effectively as possible, it must be placed in the correct location. The outdoor
sensor should be placed on the north-western or northern side of the
building to avoid the effects of the morning sun. If the sensor cannot be
placed as recommended, ensure that this is protected from direct sun
light.
Page 23
23
100% GEOTHERMAL HEAT
The sensor is placed approximately 2/3 of the way up to the wall of the
building near the corner. A sensor should not be placed under a roof, in
a place protected from the wind or over a vent, doors or windows where
the temperature is not the normal outdoor temperature.
Device Terminal Block No. Conductor Type
Outdoor sensor NTC X 1/10 and X 1/2 2 X 0,7 mm

4.3.2. Storage tank and heat distribution sensors
In Esi/Emi model with separate storage tank are the temperature sensors
installed in the same water space on the top section of the storage tank. In
such case same temperature settings are used for the top and lower sections of the storage tank. The connections diagrams for cases where the
ground source heat pump is connected to a Lämpöässä storage tank are
found at Lämpöässä website. Heat distribution circuit sensors must be
installed to the distance of approx. 0.5 m from the three-way or four-way
valve to the owing line of the heat distribution circuit.
4.3.3. Room sensor (optional)
In order for the room sensor to detect average indoor temperatures as
reliably as possible, it must be placed in a central and open location, for
example a hallway between several rooms or the staircase. String a bipolar electrical line (at least 0.5 mm2) from the heat pump to the room
sensor. Position the room sensor approximately 2/3 of the way up the
wall. Connect the room sensor lead to the heat pump.
Device Terminal Block No. Conductor type
Room sensor NTC X 1/4 and X 1/2 2 X 0,7 mm

4.3.4. Current monitor
If the equipment has been installed in the part-power conguration, load
limiting relays must be installed to the building’s master electrical switchboard, if necessary. These relays are intended to reduce the power of the
ground source heat pump’s electric heating element by phases if the phase
current passing through the building’s master fuses approaches the master
fuse nominal current.
Current monitoring relay installations and connection
Load limiting relays are connected downstream of the master electrical
switchboard’s master fuse so that the entire building’s main current
passes through the relays. Contact data of load limiting relays are wired
by quadrupole cable from the master switchboard to the ground source
heat pump electrical switchboard, where they are connected to the control circuit diagram.
These settings are initial and may require changing. Relays must always
be adjusted in a case-specic manner.
• Choose correct current
range
• Turn switch 2 to position
ON (if master fuse size is
less than 50 A)
• Other switches 1, 3-6 to
position OFF.
• Adjust hysteresis, current % and delay using
screws in the front part
(master fuses 25 A)

Electrician’s checklist
Check that
• all phases going to the switchboard are in the correct phase
sequence
• the master fuse is of sufcient size
• the ground source heat pump’s fuse size is correct, type: slow (C
curve)
• if necessary, current monitor has been installed to the building’s
master electrical switchboard (part-power models)
• the main cable is of sufcient size
4.4. Commissioning
Before commissioning, check that:
• the heating system has been connected, lled and de-aerated
appropriately
• the ground circuit has been installed, lled and de-aerated
appropriately
• electrical connections have been made appropriately and the
outdoor sensor (and optional room sensor) has been installed
• after preventing the compressor from starting, water in the storage tank has been heated by the electric heating element for at
least 6 hours
If the ground source heat pump is started for the rst time without
pre-heating, compressor will be damaged. Fill the storage tank with
water and prevent the compressor from starting by pressing down the
red compressor motor circuit breaker. Switch on the ground source heat
pump’s power supply, the electric heating element begins to heat the
water contained in storage tank. A regulator alarm goes on and the text
“Compressor 1 circuit 1 some motor protection gone off. Check motor
protection F1, F2 or F3” appears on the display. Later another regulator
alarm goes on and the text “Resistor functioned in full power system”
appears. These alarms do not require taking any measures. Starting of
the compressor is allowed after six hours of pre-heating.
NOTE!
A compressor started without pre-heating
is not covered by warranty!

5. MAINTENANCE
5.1. Maintenance and care
The Lämpöässä ground source heat pump is an easy-care and reliable
heating system that does not require regular maintenance. If the installation is carried out with care and in accordance with the instructions
provided, there is usually no need for maintenance. The ll container and
mixture circuit lter should be checked every couple of weeks during the
rst few months and afterwards approximately once a month for the rst
year of use thereafter. Also in pressurized systems it should be checked
regularly that the pressure stays at approx. 1 bar.
Lämpöässä heat pumps which includes 3-6 kg refrigerant are hermatically sealed and therefore annual inspection is not required. You are
offered the possibility of concluding an agreement on periodic inspections, in connection with which the operation of the Lämpöässä heat
pump is covered stage by stage. The observations are registered in the
inspection record and necessary measures taken (such as adjustments,
for example). For additional information on the periodic inspection agreement, visit huolto@lampoassa..

If the temperature at storage tank bottom part is lower than that of the heat
distribution circuit, the storage tank temperature is automatically increased
so as to meet the heat distribution circuit temperature with additional divergence value. Adjustment range 0...10 °C, factory setting 2 °C.
The following settings are possible for all circuits:
Setting Description Example
Reverse control
(ON/OFF)
Reversing of position
valve adjustment

In the OFF position, if voltage is
0 V, the regulator is in its extreme
right position. In the ON position, if
voltage is 0 V, the regulator is in its
extreme left position.
Adjustment range
(10...600°C)
The divergence from
target temperature in
which case the position valve is adjusted
from one extreme
position to another.
Factory setting: 300
°C.*
If the adjustment range is 140 °C
and the target temperature differs
from the current temperature by 14
°C, the valve is adjusted to 10% of
the maximum. If the temperature
changes too quickly, the adjustment range is increased. If the
temperature changes too slowly, the
adjustment range is decreased.
Integration time
(5...300 s)
Temperature divergence correction
interval(s). Factory
setting: 50 s.**
If integration time is 10 s, the valve
position is changed once in every
10 s, if required.
Derivative time
(0...10 s)
Temperature divergence reaction time.
Factory setting: 0.
The longer the derivative time, the
more the regulator position changes
upon each adjustment. Consider
that increase in derivative time
may result in increased regulator
uctuation.
Voltage
