Safety precautions
Caution
The installation must be carried out by a qualified installer.
If you install the system yourself, serious problems may occur, for
example water leaks, refrigerant leaks, electric shocks, fire and
personal injury, as a result of a system malfunction.
Use original accessories and the stated components for the
installation.
If parts other than those stated by us are used, water leaks, electric
shocks, fire and personal injury may occur as the unit may not work
properly.
Install the unit in a location with good support.
Unsuitable installation locations can cause the unit to fall and cause
material damage and personal injury. Installation without sufficient
support can also cause vibrations and noise.
Ensure that the unit is stable when installed, so that it can
withstand earthquakes and strong winds.
Unsuitable installation locations can cause the unit to fall and cause
material damage and personal injury.
Especially for units intended for R407C and R410A
- Do not use other refrigerants that those intended for the unit.
- Do not use charging bottles. These types of bottles change the
composition of the refrigerant, which makes the performance of
the system worse.
- When filling refrigerant, the refrigerant must always leave the
bottle in liquid form.
- R410A means that the pressure is about 1.6 times as high as for
conventional refrigerants.
- The filling connections on units with R410A are different sizes, to
prevent the system being filled with the incorrect refrigerant by
mistake.
Serial number
The serial number can be found at the bottom right of
the front cover, on the type plate PF1, (see IHB chapter
Heat Pump Design for location) and in the info menu
(menu 3.1).
The electrical installation must be carried out by a qualified
electrician and the system must be connected as a separate
circuit.
Power supply with insufficient capacity and incorrect function can
cause electric shocks and fire.
Use types of pipe and tools stated for this type of refrigerant.
Using existing parts for other refrigerants can cause breakdowns
and serious accidents due to process circuit bursts.
Do not perform any repairs yourself. Consult the dealer if the
system requires repair.
Incorrectly performed repairs can cause water leakage, refrigerant
leakage, electric shocks or fire.
Consult the dealer or an expert regarding removal of the heat
pump.
Incorrect installation can cause water leakage, refrigerant leaks,
electric shocks or fire.
Switch off the power supply in the event of a service or inspection.
If the power supply is not shut off, there is a risk of electric shocks
and damage due to the rotating fan.
Do not run the unit with removed panels or protection.
Touching rotating equipment, hot surfaces or high voltage parts
can cause personal injury due to entrapment, burns or electric
shocks.
Cut the power before starting electrical work.
Failure to cut the power can cause electric shocks, damage and incorrect function of the equipment.
Care
Serial number
Caution
Always give the product's serial number (14 digits) when reporting a fault.

You can select heating or cooling in the curve menu.
The next menu (heating curve/cooling curve) shows the
heating and cooling curves for your house. The task of
the curve is to give an even indoor temperature, regardless of the outdoor temperature, and thereby energy
efficient operation. It is from these heat curves that the
heat pump’s control computer determines the temperature of the water to the system, the supply temperature,
and therefore the indoor temperature. Select the curve
and read off how the supply temperature changes at
different outdoor temperatures here. The number to the
far right of "system" displays which system you have selected the heating curve/cooling curve for.
Curve coefficient
The slopes of the heating /cooling curves indicate how
many degrees the supply temperature is to be increased/reduced when the outdoor temperature
drops/increases. A steeper slope means a higher supply
temperature for heating or a lower supply temperature
for cooling at a 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.
The curve is set when the heating installation is installed,
but may need adjusting later. Normally, the curve will
not need further adjustment.
14
Chapter 3 | Control - Menus
Curve offset
An offset of the curve means that the supply temperature
changes by the same amount for all the outdoor temperatures, e.g. that a curve offset of +2 steps increases the
supply temperature by 5 °C at all outdoor temperatures.
Flow line temperature– maximum and minimum
values
Because the flow line temperature cannot be calculated
higher than the set maximum value or lower than the
set minimum value the heating curve flattens out at
these temperatures.
Caution
Under floor heating systems are normally max
flow line temperature set to between 35 and
45 °C.
Must be restricted with underfloor cooling min.
flow line temp. to prevent condensation.
Check the max temperature for your floor with
your installer/floor supplier.
The figure at the end of the curve indicates the curve
slope. The figure beside the thermometer gives the curve
offset. Use the control knob to set a new value. Confirm
the new setting by pressing the OK button.
Curve 0 is an own curve created in menu 1.9.7.
To select another curve (slope):
NOTE
If you only have one climate system, the number
of the curve is already marked when the menu
window opens.
1. Select the climate system (if more than one) for
which the curve is to be changed.
2. When the climate system selection has been confirmed, the curve number is marked.
3. Press the OK button to access the setting mode
4. Select a new curve. The curves are numbered from
0 to 15, the greater the number, the steeper the
slope and the greater the supply temperature. Curve
0 means that own curve (menu 1.9.7) is used.
5. Press the OK button to exit the setting.
To read off a curve:
1. Turn the control knob so that the ring on the shaft
with the outdoor temperature is marked.
2. Press the OK button.
NIBE F1345
3. Follow the grey line up to the curve and out to the
left to read off the value for the supply temperature
at the selected outdoor temperature.
4. You can now select to take read outs for different
outdoor temperatures by turning the control knob
to the right or left and read off the corresponding
flow temperature.
5. Press the OK or Back button to exit read off mode.
TIP
Wait 24 hours before making a new setting, so
that the room temperature has time to stabilise.
If it is cold outdoors and the room temperature
is too low, increase the curve slope by one increment.
If it is cold outdoors and the room temperature
is too high, lower the curve slope by one increment.
If it is warm outdoors and the room temperature
is too low, increase the curve offset by one increment.
If it is warm outdoors and the room temperature
is too high, lower the curve offset by one increment.
Menu 1.9.2 - external adjustment
climate system
Setting range: -10 to +10 or desired room temperature if the room sensor is installed.
Default value: 0
Connecting an external contact, for example, a room
thermostat or a timer allows you to temporarily or periodically raise or lower the room temperature while
heating. When the contact is on, the heating curve offset
is changed by the number of steps selected in the menu.
If a room sensor is installed and activated the desired

Room sensors to control the room temperature can be

Caution
A slow heat-releasing heating system, such as
for example, underfloor heating, may not be
suitable for control using the heat pump's room
sensor.
Here you can set a factor (a numerical value) that determines how much an over or sub normal temperature (the
difference between the desired and actual room temperature) in the room is to affect the supply temperature
to the climate system. A higher value gives a greater and
faster change of the heating curve's set offset.
NOTE
Too high a set value for "factor system" can
(depending on your climate system) produce
an unstable room temperature.
If several climate systems are installed the above settings
can be made for the relevant systems.

Caution
If you choose mode "add. heat only" the compressor is deselected and there is a higher operating cost.
"addition" is what helps the compressor to heat the accommodation and/or the hot water when it cannot
manage the whole requirement alone.
"heating" means that you get heat in the accommodation. You can deselect the function when you do not
wish to have heating running.
"cooling" means that you get cooling in the accommodation in hot weather. You can deselect the function when
you do not wish to have the cooling running. This alternative requires the accessory for cooling to be installed

be easier to drain the system first. This can be done in
different ways depending on what needs doing:
NOTE
■ The compressor and brine pump for each cooling
module are off.
■ Accessories are switched off.
There may be some hot water when draining
the heating medium side/climate system. There
is a risk of scalding.
■ Internal heating medium pumps are active.

If, for example, the heating medium pump requires replacing or a cooling module requires servicing, drain the
heating medium side as follows:
1. Close the shut-off valves outside the heat pump for
the heating medium side (return and flow line).
2. Connect a hose to the bleed valve (QM1) and open
the valve. Some liquid will run out.
3. Air must get into the system for the remaining liquid
to run out. To let in air, loosen the connection slightly
at the shut-off valve that joins the climate system
with the heat pump by connection (XL2) for the respective cooling module.
When the heating medium side is drained, the required
service can be performed and/or replacement of any

Alarm
If the operational interference is not shown in the display
the following tips can be used:
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.
Basic actions
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.
■ The building's earth circuit breaker.
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, see the troubleshooting section
(page 49).
■ The heat pump's temperature limiter (FD1).
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.
NOTE
To select aid mode an alarm action must be selected in the menu 5.1.4.
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.
Start by checking the following possible fault sources:
■ The switch's (SF1) position.
■ Group and main fuses of the building.
■ The heat pump's miniature circuit breaker (FC1).
■ Correctly set load monitor (if installed).
Low hot water temperature or a lack of hot
water
■ Closed or choked filling valve
– Open the valve.
■ Mixing valve (if there is one installed) set too low.

Resetting the A alarm
Alarm list
Alarm numbers 1 - 39 are reset automatically when a
fault free sensor has been connected for 60 sec. or by
manual resetting in the alarm menu.
A-alarm
At an A alarm the red light shows on the front and an
alarm icon is displayed and the alarm relay is activated
(if the AUX output is selected for this in menu 5.4). First
go through the suggested actions shown in the display.
Depending on the settings in menu 5.1.4 the heat pump
can stop producing hot water and/or reduce the room
temperature to alert you to the fact that an alarm has
occurred.
Alarm numbers 40 - 53 are reset manually in the alarm
menu.
Alarm number 54 is reset by resetting the motor protection breaker and by manually resetting the alarm in the
alarm menu.
Alarm numbers 55 - 57 are reset manually in the alarm
menu.
Alarm numbers 70-99 reset automatically when the
communication is resumed.
Caution
The alarm texts in the display can vary depending on how many heat pumps are connected to
the system.
Among other things, text can be added depending on what heat pump the alarm applies
(EB10# where EB100 is the master and EB101 –
EB108 is the slave 1 – slave 8) and where in the
heat pump the component that alarms is (for
example EP14 which is the lower cooling module).
