Techn l gy in and ar und the heat pump
The heat pump consists of four main parts:
1. Evaporator
The evaporator evaporates the refrigerant to gas and transfers heat
from the heat transfer fluid to the refrigerant circuit.
. Condenser
The condenser condenses the vapour to fluid again and transfers the
heat to the heating system.
3. Expansion valve
Lowers the pressure of the refrigerant.
4. Compressor
The compressor increases the pressure of the refrigerant.
These four main parts are linked in three circuits. A refrigerant
circulates in the heat pump, which in some parts of the circuit is in a
liquid state and in other parts in a gas state. Read more about the
properties of the refrigerant in the text box to the right.
ee the detailed description of the technologies used in the heat pump
on the next page.
Technical inf rmati n
Boiling point in relation to the
pressure:
The boiling point of different liquids
varies with pressure, the higher the
pressure, the higher the boiling point.
For example, water boils at +100ºC at
normal pressure. Double the pressure
and water boils at +120ºC. Half the
pressure and water then boils at +80ºC.
The refrigerant in the heat pump acts
in the same way. The boiling point
changes when the pressure changes.
However, the boiling point of the
refrigerant is as low as -40ºC at
atmospheric pressure. Consequently,
it is also suitable for low heat source
temperatures.
This is h w y ur heat pump w rks
The heat pump c llects st red S lar energy
The heat pump has been manufactured for easy and reliable use as well as to provide your house with inexpensive and
environment friendly heating. The easiest way to describe how a heat pump works is to say it works like a refrigerator, but in
reverse. In a refrigerator, heat is moved from the inside to the outside. In a heat pump, heat stored in the ground, rock or
water, is moved into the house. The heat pump collects a few degrees of the stored olar energy. The heat is transferred into
the house via a collector system. The temperature is then increased in the heat pump and the heat is distributed to the
house heating system.

Heat transfer fluid in. The heat pump collects stored olar energy. It contains a heat transfer fluid which is a solution
of water and an antifreeze called glycol. The antifreeze mixture collects the heat from the rock and with the help of
the heat transfer fluid it is fed into the evaporator. The temperature is then approximately 0ºC.
In the evaporator, the heat transfer fluid meets the refrigerant. At this stage, the refrigerant is in a fluid state and is
at approximately -10ºC. When the refrigerant meets the zero degree heat transfer fluid it starts to boil. It then forms
a vapour, which is fed into the compressor. The temperature of the vapour is 0ºC.
The pressure of the refrigerant increases in the compressor and the vapour temperature rises from 0ºC to
approximately +100ºC. The warm gas is then forced into the condenser.
The condenser transfers the heat to the central heating and domestic hot water systems. The vapour is cooled in the
condenser and becomes fluid. The pressure in the refrigerant is still high when it reaches the expansion valve.
The refrigerant pressure is lowered in the expansion valve. At the same time, the temperature also drops to
approximately -10ºC. When the refrigerant passes the valve and the evaporator it changes to vapour again. There is a
valve to regulate the flow of refrigerant.
The heat transfer fluid is fed out from the heat pump to the rock to collect new stored energy. The heat transfer
fluid leaves the heat pump to collect new stored olar energy. The temperature of the fluid is approximately -3ºC.

What to do if a fault occurs
C ntr l unit Reg 637
The control unit is the brains of the heat pump. It makes sure the heat
pump gives the best energy savings and that it runs for many years. The
control unit controls and monitors the heating and hot water supply in
your house. The monitoring function is especially important. It shuts
down the heat pump in the event of operational disturbances so that no
critical parts are damaged.
Electric heater gives more output
When the heat pump cannot manage to heat the house by itself, for
example, if there is a considerable drop in the outdoor temperature, the
control unit ensures the additional electric heater is connected. The heat
pump and electric heater help to maintain the temperature required in
the house. The electric heater only adds the output necessary for the
heat pump to be able to produce the right temperature. When the heat
pump can once again manage heating on its own the electric heater is
automatically disconnected.
Domestic hot water (DHW) is given priority over
central heating water
In a house with water based heating a difference is made between
central heating water and domestic hot water (DHW). The central
heating water is for radiators/underfloor heating and domestic hot water
(DHW) is for showers and taps. The hot water heater is fitted with a
sensor that measures the temperature of the hot water. The unit ensures
that priority is given to the domestic hot water (DHW) over the heating
demands.
Sensor fault
All sensors connected to the heat pump can give an alarm when
defective. In the example to the right it is sensor T1 (GT1), Return
radiator, which has given an alarm. All sensors give alarms in the same
way. Read more about the sensors under heading Read the temperatures
on the heat pump.
Possible cause 1: Temporary error.
Action: 1. Monitor performance of product.
Possible cause : Short circuit or broken sensor cable.
Action: 1. If you have a multimeter you can disconnect the
sensor and check the cables resistance. Compare
with the sensor table in the section Technical
information.
Possible cause 3: Defective sensor or incorrect connection.
Action: 1. Replace sensor/check connection.
HTF in under limit T10 (GT10) and HTF out
under limit T11 (GT11)
Possible cause 1: Temporary low heat transfer fluid

Action: 1. Monitor performance of the heat pump.
2. If the alarm returns, contact Technical
Department.
Possible cause : Too low flow on the collector circuit.
Action: 1. Check the filter.
2. Clean the filter if it is blocked.
Possible cause 3: The minimum heat transfer fluid temperature
has been set too low.
Action: 1. If the alarm returns, contact the Technical
Department.
In a ground water system the cause may also be:
Possible cause 4: Blocked filter in the groundwater circuit.
Action: 1. Clean the filter.
Possible cause 5: The motor cut-out or a fuse on the pump in
the groundwater system has tripped.
Action: 1. Reset the motor cut-out or fuse.
Possible cause 6: Faulty pump in the groundwater circuit.
Action: 1. Contact the Technical Department.

The c ntr l units tw meth ds t c ntr l
the heat pump
The control unit uses two different methods to control the heat pump.
These two methods are A or B, as below:
A: Control with outdoor sensor
A sensor is installed on the outside, North facing wall of the house.
Control with an outdoor sensor means that the heat pump automatically
regulates the heating in the house depending on the outdoor
temperature. If the outdoor temperature drops, the radiators/underfloor
heating inside the house will become warmer.
The user determines the response from the heat pump in relation to the
outdoor temperature, with the help of a number of settings such as
selecting the heat curve on the control unit. Further explanation is given
later in this manual.
B: Control with outdoor sensor supplemented
with room sensor
Control with an outdoor sensor supplemented with a room sensor means
that you also place a sensor in a reference position inside the house. This
is connected to the heat pump and provides the control unit with
information about the room temperature. The signals affect the control
units settings (curves) and ensure the heat pump gives the best possible
energy savings.
This control method is used when factors other than the outdoor
temperature influence the indoor temperature. uch as a secondary
source of heating.
High Heat transfer fluid delta T8/T9 (GT8/GT9)
The heat pump gives an alarm when the temperature difference between
the sensors T8 (GT8) and T9 (GT9) is too high.
Possible cause 1: Not enough flow over the heat pump.
Action: 1. Check that the heat carrier pump has not
jammed.
2. Check that all the valves are open. Radiator
thermostat valves should be fully open and
underfloor heating systems should have at least half
of the coils fully open.
Possible cause : The filter on the primary circuit is blocked.
Action: 1. Clean the filter.
High return to the heat pump T9 (GT9)
ensor T9 (GT9) in the heat pump stops the compressor if the
temperature of the return water from the radiators becomes too high.
The limit is at approximately 57ºC.

The heat pump is in standby mode.
The heat pump is producing hot water. The present temperature and
temperature at which the heat pump will stop is shown. Note that the
stop temperature is read at the bottom of the heater. The hot water is a
few degrees warmer.
The heat pump and electric heater are running.
The heat pump has received signals that it should produce heating. It
now waits for the restart time to countdown to zero.
Return to the initial menu by pressing one of the buttons or turn the dial.
Set the heating
It is easy to set the heating level on the heat pump. However, before it is
explained how to do this it is important to understand the relation
between the outdoor temperature, return temperature and heat curve
slope. The easiest way to explain the relation is with a heat curve.
Heat curve
The heat curve is used to set the indoor temperature. The heat pump is
controlled by the outdoor temperature. When the weather becomes
colder, the heat pump ensures more heating is produced automatically.
Return temperature:
The return temperature is the temperature of the water that returns to
the heat pump from the radiators/underfloor heating. The flow
temperature of the heat pump is normally 7-10ºC higher than the return
temperature. When the outdoor temperature is -10ºC and curve 4 is set,
the pump attempts to keep the return water at approximately 40ºC.
Outdoor temperature:
The outdoor temperature determines how much heating the heat pump
should produce. A sensor placed outdoors sends signals to the control
unit, which then adjusts the heat pump. The sensor must be fitted to a
North facing wall outdoors.
Curve slope:
The curve slope can be changed to increase or decrease the heating in
the house. The scale is between 0-10.
All alarms
There are many reasons why the alarm occurs. However, there is never a
risk involved in resetting an alarm. All the alarms that can appear in the
menu display are described on the following pages. The descriptions
give an idea about the nature of the alarm and how to rectify it. The text
often refers to different fuses and reset buttons on the heat pump as
shown in the diagram above.
On delivery the heat pump curve slope
is set to position 4. This means that
the return temperature is +35ºC when
it is 0ºC outdoors.

What to do if a fault occurs
Change the curve slope
The heat pumps production of heat is adjusted by increasing or
decreasing the curve slope in the Heat. incr. / decr. menu. This is
especially effective in cold weather conditions.
Dashed line:
If the return temperature exceeds 57ºC an alarm is given and the
compressor switches off. The heat pump starts automatically when the
return temperature drops.
In cold weather (below +5ºC):
If the indoor temperature, when it is colder than +5ºC outdoors, is not
satisfactory, the slope of the heat curve must be changed as follows:
1. Press the Temperature button in the initial menu.
2. Press the Adjust button.
3. Turn the menu dial clockwise to increase the heating.
Turn the menu dial anti-clockwise to lower the heating.
(Adjust in small increments, 0.2-0.6 units, is usually enough.)
4. ave the new value by pressing the ave button.
What t d if a fault ccurs
The control unit has an advanced monitoring system that gives alarms if
anything unforeseen happens in the heat pump. Most alarms are
rectified by the user without any damage to the heat pump.
If a room sensor is installed the indicator will come on when the heat
pump gives an alarm.
Example of an alarm:
Info button:
Press the Info button and turn the menu dial to display information of
possible actions to rectify the alarm.
Ackn. button:
Press the Ackn. button, the alarm indicator on the control panel goes out
and the heat pump starts again within 15 minutes if there is a heating
requirement. If the fault has not been rectified the indicator will remain
illuminated. hould several alarms have occurred on the heat pump, turn
the menu dial clockwise for more information of each alarm.
Menu display dimmed
Possible cause 1: Power failure in the house consumer unit.
Action: 1. Check the fuses in the house consumer unit.
2. If a miniature circuit-breaker has tripped, reset
the circuit breaker. Change the fuse if necessary.
3. The heat pump automatically returns to its
operating mode 15 minutes after the fault has been
rectified.
Possible cause : The heat pumps miniature circuit-breaker has
tripped.
Action: 1. Reset the heat pumps miniature circuit-breaker
by pushing up the centre toggle switch.
2. The heat pump automatically returns to its
operating mode 15 minutes after the fault has been
rectified.
Wait at least two days when increasing
or decreasing the heating before
making a new adjustment.
If it is still difficult to get a comfortable
indoor temperature at an outdoor
temperature around 0ºC, despite
several attempts, adapt the heat curve.
Read about how to adapt the curve
in the section Extra functions 
Customer level 2 / Temperature
settings / Adapting the heat curve.
Curve slope:
2-4 Normal setting for underfloor
heating.
4-6.5 Normal setting for radiators.
7-10 Abnormal high setting.
From the heat curve it can be seen
that curve slope 4 gives a return
temperature of +35ºC when it is 0ºC
outdoors. If the outdoor temperature
drops the return temperature
increases. At an outdoor temperature
of approximately -30ºC the curve slope
has nearly reached the limit value
(+57ºC) for the return temperature.
For technical reasons the heat pump
does not restart until 15 minutes after
a stoppage.

Fine-tune the heat curve
The heat curve can also be fine-tuned. Fine-tuning means that the heat
curve is offset in parallel. Fine-tuning is done from the Heat. fine-tune
menu. The diagram for fine-tuning shows how the dashed line has been
offset upwards in parallel. This means the heating has been fine-tuned in
a positive direction and the heat pump will be instructed to maintain a
higher temperature on the return water at all outdoor temperatures.
In warm weather (above +5ºC):
If the indoor temperature is not satisfactory when it is above +5°C
outdoors, the curve may be offset in the Heat. fine-tune menu as follows:
1. Press the Temperature button in the initial menu.
2. Turn the menu dial clockwise until the menu Heat. fine-tune.3 is
reached.
3. Press the Adjust button.
4. Turn the menu dial clockwise to increase the room temperature.
Turn the menu dial anti-clockwise to lower the room temperature.
(Adjust in small increments, 0.2-0.6 units, is usually enough.)
5. ave the new value by pressing the ave button.

Manual test run f the heat pump
Instead of starting the heat pump directly in normal mode, manually test
run the pumps and valves. This is recommended as in this mode possible
faults can be found. In the menu display Manual operation of all
functions (menu 5.3) all functions can be run manually. Press the elect
button to start test operations. When exiting from the menu display the
heat pump returns to normal mode.
Start the heat pump with the electric heater

heat. Now press the ave button. This function ensures that electric
heater heats both the central heating water and the domestic hot water
(DHW).
Imp rtant p ints t check after start up
In the first period after commissioning particular attention should be
paid to the pressure and levels in the heat distribution and heat transfer
fluid circuits. After a short period of operation it may be necessary to top
up the heat transfer fluid.
On delivery the motor cut-out setting is determined by a value produced
during hot water charging and a stable voltage. The recommended
motor cut-out setting may not always be suitable as the voltage in the
mains can fluctuate. The setting may therefore, from case to case, need
to be adjusted. Adjust the setting using a clip-on ammeter when the heat
pump is producing hot water.
For the heat pump to perform at its best, it is important to check the flow
on the primary circuit of the heat pump. Usually, the heat carrier pump
has a speed selector switch. This must be set correctly for the pressure
drop in the systems. A recommended temperature difference over the
heat pump on the primary circuit is between 7-10 °C and on the collector
circuit between 2-4 °C. Check this by going to menu display 3 and
reading the sensors T8 (GT8) and T9 (GT9) as well as T10 (GT10) and
T11 (GT11).
It is important in systems with a bypass that the flow in the heating
system exceeds the flow over the heat pump. If this is not the case, the
heat pump flow goes back via the bypass to the heat pump return, which
may cause the heat pump to give an alarm for a high return temperature.
The flow over the heating system should be enough to ensure that the
entire radiator surface is kept warm. In this way the heat emitting
surface increases and in doing so the flow temperature from the heat
pump is kept down.
The heating system should be vented once again after test operations
and then filled with cold water if necessary.
The example describes how to set the
required room temperature with the
help of a connected room sensor. The
range is 10ºC to 30ºC.
When the set time has elapsed you
must repeat the setting to get extra
hot water again.
Do not forget to return this function
to normal mode.

Drying pr gram f r fl r screed
When the heat pump has been installed in a newly built house with
underfloor heating, the Drying for floor screed function can be used.
The function is designed to slowly heat up the floor for a set number of
days. The temperature is then maintained for a set number of days,
finally allowing the floor to cool slowly for a set number of days. The heat
pump works during drying operations with the hysteresis set in the
display P1.4.
et how many days you want the heating phase to last.
et how many days you want the floor heating system to maintain the
maximum drying temperature.
et how many days you want the cooling phase to last.
et the start and stop temperatures for the drying program.
et the maximum temperature that the drying program should work at.
The function is activated and deactivated here. Drying program.
Each menu is numbered in the lower
right-hand corner; this indicates which
main display it is associated to.
During drying operations the heat
pump does not produce any hot water
and is not affected by timer controls.
Once the drying program has finished
the heat pump returns to normal mode.
When an extra shunt group is installed,
it works according to the normal heat
curve. The mixing valve must be
opened manually when this circuit is
also to be included in the drying
program.

All menus relating to temperature sensors
All the menus associated with the heat pump temperature sensors are
shown below. Note that the user cannot make any changes to the
settings in these menus, only read the current values. ome menus are
standard for all models of Greenstore while others are only available in
combination with different accessories. The sensors give an alarm if the
temperature is outside of the permitted range/values.
Read the start delay
The function shows the time remaining until the heat pump starts again
after a previous stoppage. The heat pump will not start if there is no
heating or hot water demand.
Setting the electric heater
Electric heat timer
The function gives you the possibility to set the time that should elapse
before the electric heater starts if the heat pump cannot produce
sufficient heat on its own. On delivery the heat pump is set to one hour.
Ramp time open
Here you set the time that is required for the electric heater to go from 0
to 100%. In some cases the ramp time open, may need to be adjusted to
eliminate over exciting the system.
Ramp time close
Here you set the time that is required for the electric heater to go from
100 to 0%.

temperature.
The menu shows the outdoor temperature. ome deviation compared to the true temperature
may occur due to thermal radiation from the house to the installed outdoor sensor.
The menu shows the set and present temperature in the lower section of the outer container in
the hot water heater. The temperature is approximately 5ºC lower than the temperature of the
hot water inside the inner container.
This menu only applies together with a flow sensor. If an extra curve with mixing valve is used,
for example, for an underfloor heating system, you can see the temperature on the flow water in
the circuit. The temperature varies with the outdoor temperature.
The menu is only applicable together with a room sensor. The menu shows the set point value
and present temperature in the room where the sensor is fitted.
The menu shows the compressors working temperature. The temperature varies between 70ºC
and 125ºC during operations.
The menu shows the flow temperature of the central heating water as it leaves the heat pump. It
varies depending on the outdoor temperature and whether the heat pump is in domestic hot
water (DHW) heating mode.
The menu shows the temperature of the water that is fed into the heat pump. It varies
depending on the outdoor temperature and whether the heat pump is in domestic hot water
(DHW) heating mode. The heat pump stops at 57ºC for safety reasons.
The menu shows the temperature of the heat transfer fluid that is fed into the heat pump from
the bore hole or the ground collectors. It can vary between -5ºC to +15ºC during a season.
The menu shows the temperature of the heat transfer fluid that is fed out of the heat pump to
the bore hole or the ground collectors. Normally, during operations, it is 1.5 - 5.0 degrees lower
than the heat transfer fluid that is fed into the heat pump.
