NIBE™ F1245PC
F1245PC – An excellent choice
F1245PC is part of a new generation of heat pumps, which have been introduced to supply your home with inexpensive and environmentally
friendly heating and/or cooling. Heat production is safe and economical
with integrated hot water heater, immersion heater, circulation pump
and control system.
The heat pump can be connected to an optional low temperature heat
distribution system. e.g. radiators, convectors or underfloor heating. It is
also prepared for connection to several different products and accessories,
e.g. extra hot water heater, ventilation recovery, pool and climate systems
with different temperatures.
The heat pump can be connected to an optional low temperature heat
distribution system. e.g. radiators, convectors or underfloor heating. It is
also prepared for connection to several different products and accessories,
e.g. water heater, ventilation recovery, pool and climate systems with different temperatures.
An immersion heater of 7 kW can be connected automatically if anything
unforeseen should occur or as emergency operation (factory setting 6
kW).
For F1245PC-16 3x400V, an immersion heater of 7 kW can be connected
automatically if anything unforeseen should occur or as back-up operation
(factory setting 6 kW).
F1245PC is equipped with a control computer for good comfort, good
economy and safe operation. Clear information about status, operation
time and all temperatures in the heat pump are shown on the large and
easy to read display. This means, for example, that external unit thermometers are not necessary.
Excellent properties for F1245PC:
■
Integrated water heater
There is a water heater integrated in the heat pump, which is insulated
with environmentally friendly cellular plastic for minimal heat loss.
■

Heat pump function
A heat pump can use stored solar energy from rock, ground or water in
order to heat a property. The conversion of stored energy in nature to
property heating occurs in three different circuits. In the brine circuit, (1)
, free heat energy is retrieved from the surroundings and transported to
the heat pump. In the refrigerant circuit, (2) , the heat pump increases the
retrieved heat's low temperature to a high temperature. In the heating
medium circuit, (3) , the heat is distributed around the house.
The temperatures below are only examples and may vary between different
installations and times of year.

Brine circuit
In a hose, collector, an anti-freeze liquid, brine, circulates from the heat
pump out to the heat source (rock/ground/lake). The energy from the
heat source is stored by it heating the brine a few degrees, from about
–3°C to about 0 °C.
The collector then routes the brine to the heat pump’s evaporator. Here,
the brine releases heat energy and the temperature drops a few degrees.
The liquid then returns to the heat source to retrieve energy again.
Refrigerant circuit
Another liquid circulates in a closed system in the heat pump, a refrigerant,
which also passes the evaporator. The refrigerant has a very low boiling
point. In the evaporator the refrigerant receives the heat energy from the
brine and starts to boil.
The gas that is produced during boiling is routed into an electrically
powered compressor. When the gas is compressed, the pressure increases
and the gas's temperature increases considerably, from approx. 5ーC to
approx. 100 ーC.
From the compressor, gas is forced into a heat exchanger, condenser,
where it releases heat energy to the heating system in the house,
whereupon the gas is cooled and condenses to a liquid form again.
As the pressure is still high, the refrigerant can pass an expansion valve,
where the pressure drops so that the refrigerant returns to its original
temperature. The refrigerant has now completed a full cycle. It is routed
to the evaporator again and the process is repeated.
Heat medium circuit
The heating energy that the refrigerant releases in the condenser is retrieved by the heat pump's boiler section.
The heating medium circulates in a closed system and transports the heated
water's heat energy to the house water heater and radiators/heating coils.

Passive cooling
The brine can also be circulated via a mixing valve to a heat exchanger.
There the brine cools the heating system's water so that comfort cooling
can be maintained during the hotter periods of the year.

Maintenance of F1245PC
Regular checks
Your heat pump is, in principle, maintenance free and therefore requires
minimal care after commissioning. On the other hand, it is recommended
that you check your installation regularly.
If something unusual occurs, messages about the malfunction appear in
the display in the form of different alarm texts. See alarm management
on page 74.
Level vessel
1/3
The brine that obtains the heat in the ground is not normally
consumed but just pumped around. In most installations, there
is a level vessel where you can check if there is sufficient fluid
in the system. Ask your installer if you are unsure where the
level vessel is located. The2/3
level can vary due to the fluid’s
1/3
temperature. If the level is below 1/3 topping up is required.
Contact your installer for assistance with filling.
LEK

LEK
Expansion vessel
LEK
Gamla bilder, med säkerhetsventil på nivåkärlet
The brine that obtains the heat in the ground is not normally
consumed but just pumped around. In some installations there
is an expansion tank instead of a level vessel (for example,
where the heat pump is not at the highest point in the brine
system) where the system pressure can be checked. Ask your
installer if you are unsure where the expansion tank is located.
The pressure can vary due to the fluid’s temperature. The
pressure should not fall below 0.5 bar. Contact your installer
for assistance with filling.
Safety valve
The water heater's safety valve sometimes releases a little water after hot
water usage. This is because the cold water, which enters the water heater
to replace the hot water, expands when heated causing the pressure to
rise and the safety valve to open.
The function of the safety valve must be checked regularly. You can find
the safety valve on the incoming pipe (cold water) to the water heater.
Perform checks as follows:
24
Chapter 2 | The heat pump – the heart of the house
NIBE™ F1245PC
1. Open the valve by turning the knob anti-clockwise carefully.
2. Check that water flows through the valve.
3. Close the valve by releasing it. If it does not close automatically when
released, turn it anti-clockwise slightly.
Saving tips
Your heat pump installation produces heat and hot water. This occurs via
the control settings you made.
Factors that affect the energy consumption are, for example, indoor temperature, hot water consumption, the insulation level of the house and
whether the house has many large window surfaces. The position of the
house, e.g. wind exposure is also an affecting factor.
Also remember:
■ Open the thermostat valves completely (except in the rooms that are to
be kept cooler for various reasons, e.g. bedrooms). The thermostats slow
the flow in the heating system, which the heat pump wants to compensate with increased temperatures. It then works harder and consumes
more electrical energy.
■ You can lower the temperature when away from the house by
scheduling "holiday setting" in menu 4.7. See page 68 for instructions.
■ If you activate "Hot water Economy", less energy is used.

month. This will indicate any changes in power consumption.
Newly built houses usually have twin energy meters, use the difference to
calculate your domestic electricity.
New builds
Newly built houses undergo a drying out process for a year. The house
can then consume significantly more energy than it would thereafter.
After 1-2 years the heating curve should be adjusted again, as well as the
offset heating curve and the building's thermostat valves, because the
heating system, as a rule, requires a lower temperature once the drying
process is complete.

certain outdoor temperature.
The optimum slope depends on the climate conditions in your location, if
the house has radiators or under floor heating and how well insulated the
house is.

4 Disturbances in comfort
In most cases, the heat pump notes operational interference and indicates
this with alarms and shows instructions in the display. See page 74 for information about managing alarms. If the malfunction does not appear in
the display, or if the display is not lit, the following troubleshooting guide
can be used.
Manage alarm
In the event of an alarm, some kind of
malfunction has occurred, which is
indicated by the status lamp changing
from green continuously to red continuously. In addition, an alarm bell
appears in the information window.
Low pressure alarm
alarm
info / action
Alarm
reset alarm
aid mode
In the event of an alarm with a red
status lamp a malfunction has occurred that the heat pump cannot
remedy itself. In the display, by turning the control knob and pressing the
OK button, you can see the type of alarm it is and reset it. You can also
choose to set the heat pump to aid mode.
info / action Here you can read what the alarm means and receive tips
on what you can do to correct the problem that caused the alarm.
reset alarm In most cases it is enough to select "reset alarm" to correct
the problem that caused the alarm. If a green light illuminates after selecting "reset alarm" the alarm has been remedied. If a red light is still visible
and a menu called ”alarm” is visible in the display, the problem that caused
the alarm remains. If the alarm disappears and then returns, contact your
installer.
aid mode ”aid mode” is a type of emergency mode. This means that the
heat pump produces heat and/or hot water despite there being some
kind of problem. This can mean that the heat pump's compressor is not
running. In this case the immersion heater produces heat and/or hot water.
Caution
Selecting "aid mode” is not the same as correcting the problem that
caused the alarm. The status lamp will therefore continue to be red.
If the alarm does not reset, contact your installer for suitable remedial action.

6 Glossary
Additional heat
The additional heat is the heat produced in addition to the heat supplied
by the compressor in your heat pump. Additional heaters can be for example, immersion heater, electric heater, gas/oil/pellet/wood burner or
district heating.
Brine
Anti-freeze liquid, e.g. ethanol or glycol mixed with water, which transports
heat energy from the heat source (rock/ground/lake) to the heat pump.
Brine side
Brine hoses, any bore holes and the evaporator make up the brine side.
Calculated flow line temperature
The temperature that the heat pump calculates that the heating system
requires for an optimum accommodation temperature. The colder the
outdoor temperature, the higher the calculated supply temperature.
Charge coil
A charge coil heats the domestic hot water (tap water) in the heater with
heating water.
Circulation pump
Pump that circulates liquid in a pipe system.
Climate system
The climate system can also be called the heating and/or cooling system.
The building is cooled or heated using radiators, under floor coils or convector fans.
Coil tank
A heater with a coil in it. The water in the coil heats the water in the
heater.
Collector
Hose where the brine circulates in a closed system between the heat source
and the heat pump.
80
Chapter 6 | Glossary
NIBE™ F1245PC
Compressor
Compresses the gas state refrigerant. When the refrigerant is compressed,
the pressure and the temperature increase.
Condenser
Heat exchanger where the hot gas state refrigerant condenses (cooled
and becomes a liquid) and releases heat energy to the house heating and
hot water systems.
Convector
Works in the same way as a radiator, but with the difference that the air
is blown out. This means that the convector can be used to heat or cool
the accommodation.
COP
If it is stated that a heat pump has COP 5, this means, in principle that if
you insert 10 pence, you will get 50 pence worth of heat. It is the efficiency
of the heat pump. This is measured at different measurement values, e.g.:
0/35 where 0 stands for how many degrees the temperature of the incoming brine is and 35 for how many degrees the supply temperature is.
Disturbances in comfort
Disturbances in comfort are undesirable changes to the hot water/indoor
comfort, for example when the temperature of the hot water is too low
or if the indoor temperature is not at the desired level.
A malfunction in the heat pump can sometimes be noticed in the form of
a disturbance in comfort.
In most cases, the heat pump notes operational interference and indicates
this with alarms and shows instructions in the display.
Domestic hot water
The water one showers in for example.
DUT, dimensioned outdoor temperature
The dimensioned outdoor temperature differs depending on where you
live. The lower the dimensioned outdoor temperature, the lower the value
should be selected on "selecting a heat curve".
Efficiency
A measurement of how effective the heat pump is. The higher the value
is the better it is.
Chapter 6 | Glossary
NIBE™ F1245PC
81
Electrical addition
This is electricity that, for example, an immersion heater uses as addition
during the coldest days of the year to cover the heating demand that the
heat pump cannot manage.
Emergency mode
A mode that can be selected using the switch in the event of a fault, which
means that the compressor stops. When the heat pump is in emergency
mode, the building and/or hot water is heated using an immersion heater.
Evaporator
Heat exchanger where the refrigerant evaporates by retrieving heat energy
from the brine which then cools.
Expansion valve
Valve that reduces the pressure of the refrigerant, whereupon the temperature of the refrigerant drops.
Expansion vessel
Vessel with brine or heating medium fluid with the task of equalising the
pressure in the brine or heating medium system.
Fan convectors
A type of convector, but with auxiliary fan that blows hot or cold air into
the accommodation.
Filtering time
Indicates the time the average outdoor temperature is calculated on.
Flow pipe
The line in which the heated water is transported from the heat pump out
to the house heating system (radiators/heating coils).
Free cooling
The cold brine from the collector/borehole is used to cool the accommodation.
Heat exchanger
Device that transfers heat energy from one medium to another without
mixing mediums. Examples of different heat exchangers are evaporators
and condensers.
82
Chapter 6 | Glossary
NIBE™ F1245PC
Heat factor
Measurement of how much heat energy the heat pump gives off in relation
to the electric energy it needs to operate. Another term for this is COP.
Heating curve
The heating curve determines which heat the heat pump is to produce
depending on the temperature outdoors. If a high value is selected, this
tells the heat pump that it must produce a lot of heat when it is cold outdoors in order to achieve a warm indoor temperature.
Heating medium
Hot liquid, usually normal water, which is sent from the heat pump to the
house climate system and makes the accommodation warm. The heating
medium also heats the hot water through the coil tank.
Heating medium side
Pipes to the house’s climate system and condenser make up the heating
medium side.
Level monitor
Accessory that senses the level in the level vessel and gives an alarm if it
becomes too low.
Level vessel
Partially transparent vessel with brine with the task of equalising the
pressure in the brine system. When the temperature of the brine increases
or decreases, the pressure in the system changes and the level in the level
vessel also changes.
Mixing valve
A valve that mixes the cold water with the hot water leaving the heater.
Outside sensor
A sensor that is located outdoors. This sensor tells the heat pump how hot
it is outdoors.
Passive cooling
See "Free cooling".
Chapter 6 | Glossary
NIBE™ F1245PC
83
Pressostat
Pressure switch that triggers an alarm and/or stops the compressor if nonpermitted pressures occur in the system. A high pressure pressostat trips
if the condensing pressure is too great. A low pressure pressostat trips if
the evaporation pressure is too low.
Radiator
Another word for heating element. They must be filled with water in order
to be used with F1245PC.
Refrigerant
Substance that circulates around a closed circuit in the heat pump and
that, through pressure changes, evaporates and condenses. During evaporation, the refrigerant absorbs heating energy and when condensing
gives off heating energy.
Return pipe
The line in which the water is transported back to the heat pump from
the house heating system (radiators/heating coils).
Return temp
The temperature of the water that returns to the heat pump after releasing
the heat energy to the radiators/heating coils.
Room sensor
A sensor that is located indoors. This sensor tells the heat pump how hot
it is indoors.
Safety valve
A valve that opens and releases a small amount of liquid if the pressure is
too high.
Shuttle valve
A valve that can send liquid in two directions. A shuttle valve that enables
liquid to be sent to the climate system, when the heat pump produces
heating for the house, and to the hot water heater, when the heat pump
produces hot water.
Supply temperature
The temperature of the heated water that the heat pump sends out to
the heating system. The colder the outdoor temperature, the higher the
supply line temperature becomes.
