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.
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 in-
spection.
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 in-
correct function of the equipment.
Care
Do not use the unit for specialist purposes such as for storing
food, cooling precision instruments, freeze-conservation of
animals, plants or art.
This can damage the items.
Dispose of any packaging material correctly.

Caution
An increase in the room temperature can be
slowed by the thermostats for the radiators or
under floor heating. Therefore, open the thermo-
stat valves fully, except in those rooms where a
cooler temperature is required, e.g. bedrooms.
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 in menu
1.9.1 by one increment.
If it is cold outdoors and the room temperature
is too high, lower the curve slope menu 1.9.1
by one increment.
If it is warm outdoors and the room temperature
is too low, increase the value in menu 1.1 by
one increment.
If it is warm outdoors and the room temperature
is too high, reduce the value in menu 1.1 by one
increment.
Menu 1.2 - ventilation (accessory required)
Setting range: normal and speed 1-4
Default value: normal
The ventilation in the accommodation can be temporarily
increased or reduced here.
When you have selected a new speed a clock starts a
count down. When the time has counted down the
ventilation speed returns to the normal setting.
If necessary, the different return times can be changed
in menu 1.9.6.
The fan speed is shown in brackets (in percent) after each
speed alternative.
TIP
If longer time changes are required use the hol-
iday function or scheduling.
Menu 1.3 - scheduling
In the menu scheduling indoor climate (heating/cool-
ing/ventilation) is scheduled for each weekday.
You can also schedule a longer period during a selected
period (vacation) in menu 4.7.
Menu 1.3.1 - heating
Increases or decreases in the accommodation temperature
can be scheduled here for up to three time periods per
day. If a room sensor is installed and activated the desired
room temperature (°C) is set during the time period.
Without an activated room sensor the desired change is
set (of setting in menu 1.1). A one degree change in room
temperature requires one increment for underfloor
heating and approximately two to three increments for
the radiator system.
If two settings conflict with each other a red exclamation
mark is displayed at the end of the line.

In the menu heating curve the so-called heating curve
for your house can be viewed. The task of the heating
curve is to give an even indoor temperature, regardless
of the outdoor temperature, and thereby energy efficient
operation. It is from this heating curve that the heat
pump’s control computer determines the temperature of
the water to the heating system, flow line temperature,
and therefore the indoor temperature. You can select
heating curve and read off how the flow line temperature
changes at different outdoor temperatures here.

The slope of the heating curve indicates how many de-
grees the supply temperature is to be increased/reduced
when the outdoor temperature drops/increases. A
steeper slope means a higher supply temperature 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 heating curve is set when the heating installation is
installed, but may need adjusting later. Thereafter the
heating curve should not need further adjustment.
Caution
In the event of making fine adjustments for the
indoor temperature, the heat curve must be
offset up or down instead, this is done in menu
1.1 temperature .

An offset of the heating curve means that the supply
temperature changes as much for all the outdoor temper-
atures, e.g. that a curve offset of +2 steps increases the
supply temperature by 5 °C at all outdoor temperatures.

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
Underfloor heating systems are normally max
flow line temperature set between 35 and 45
°C.
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 heating curve created in menu 1.9.7.
To select another heat curve (slope):
NOTE
If you only have one heating system, the number
of the curve is already marked when the menu
window opens.
1. Select the system (if more than one) for which the
heat curve is to be changed.
2. When the system selection has been confirmed the
heat curve number is marked.
3. Press the OK button to access the setting mode
4. Select a new heating curve. The heat curves are
numbered from 0 to 15, the greater the number, the
steeper the slope and the greater the supply temper-
ature. Heating 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 heating curve:
1. Turn the control knob so that the ring on the shaft
with the outdoor temperature is marked.
2. Press the OK button.
3. Follow the grey line up to the heat curve and out to
the left to read off the value for the supply temperat-
ure 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 incre-
ment.
If it is cold outdoors and the room temperature
is too high, lower the curve slope by one incre-
ment.
If it is warm outdoors and the room temperature
is too low, increase the curve offset by one incre-
ment.
If it is warm outdoors and the room temperature
is too high, lower the curve offset by one incre-
ment.
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 period-
ically raise or lower the room temperature. When the
contact is on, the heat curve offset is changed by the
number of steps selected in the menu. If a room sensor
is installed and activated the desired room temperature
(°C) is set.
If there is more than one climate system the setting can
be made separately for each system.
NIBE™ F1345Chapter 3 | Control - Menus14

Menu 1.9.3 - min. flow line temp.
climate system
Setting range: 5-70 °C
Default value: 20°C
Set the minimum temperature on the supply temperature
to the climate system. This means that F1345 never cal-
culates a temperature lower than that set here.
If there is more than one climate system the setting can
be made separately for each system.
TIP
The value can be increased if you have, for ex-
ample, a cellar that you always want to heat,
even in summer.
You may also need to increase the value in "stop
heating" menu 4.9.2 "auto mode setting".
Menu 1.9.4 - room sensor settings
factor system
Setting range: 0.0 - 6.0
Default value: 2.0
Room sensors to control the room temperature can be
activated here.
Here you can set a factor that determines how much the
supply temperature is to be affected by the difference
between the desired room temperature and the actual
room temperature. A higher value gives a greater change
of the heating curve's set offset.
If several climate systems are installed the above settings
can be made for the relevant systems.

Default values: 30 s
You can use F1345 to cool the house during hot periods
of the year.
min. temp. cooling flow
Set the minimum temperature on the supply temperature
to the climate system during cooling operation. This
means that F1345 never calculates a temperature lower
than that set here.
cooling flow temp. at +20 °C
Set the desired temperature on the flow temperature to
the climate system during cooling operation when the
outdoor temperature is +20 °C. F1345 then attempts to
get as close to the set temperature as possible.
coolant flow line at +40°C
Set the desired temperature on the flow temperature to
the climate system during cooling operation when the
outdoor temperature is +40 °C. F1345 then attempts to
get as close to the set temperature as possible.

time betw. switch heat/cool
Here you can set how long F1345 is to wait before it re-
turns to heating mode when the cooling demand has
ceased or vice versa.
close mix. valves in cool mode
If the heat pump is connected to more than one climate
system condensation may occur in these if they are not
intended for cooling.
To avoid this check "close mix. valves in cool mode",
which means that the sub-shunts for the extra climate
systems close when cooling operation is activated.
heat at room under temp.
Caution
This setting option only appears if a room tem-
perature sensor is connected to F1345 and has
been activated.
Here you can set how far the room temperature can drop
below the desired temperature before F1345 switches to
heating operation.
cool at room over temp.
Caution
This setting option only appears if a room tem-
perature sensor is connected to F1345 and has
been activated.
Here you can set how high the room temperature can
increase above the desired temperature before F1345
switches to cooling operation.
mixing valve amplifier and mixing valve step
delay
Shunt reinforcement and shunt wait time for the cooling
system are set here.
Menu 1.9.6 - fan return time (accessory re-
quired)
speed 1-4
Setting range: 1 – 99 h
Default value: 4 h
Here you select the return time for temporary speed
change (speed 1-4) on the ventilation in menu 1.2.
Return time is the time it takes before ventilation speed
returns to normal.
Menu 1.9.7 - own curve
supply temperature
Setting range: 0 – 80 °C
You can create your own heating curve here, if there are
special requirements, by setting the desired supply tem-
peratures for different outdoor temperatures.
Caution
Curve 0 in menu 1.9.1 must be selected for this
curve to apply.
Menu 1.9.8 - point offset
outdoor temp. point
Setting range: -40 – 30 °C
Default value: 0 °C
change in curve
Setting range: -10 – 10 °C
Default value: 0 °C
Select a change in the heating curve at a certain outdoor
temperature here. A one degree change in room temper-
ature requires one increment for underfloor heating and
approximately two to three increments for the radiator
system.
The heat curve is affected at ± 5 °C from set outdoor
temp. point.
It is important that the correct heating curve is selected
so that the room temperature is experienced as even.
TIP
If it is cold in the house, at, for example -2 °C,
"outdoor temp. point" is set to "-2" and
"change in curve" is increased until the desired
room temperature is maintained.
Caution
Wait 24 hours before making a new setting, so
that the room temperature has time to stabilise.

2.2 - comfort mode
2.3 - scheduling
2.9.1 - periodic increases2.9 - advanced
* Accessory needed.
Sub-menus
For the menu HOT WATER there are several sub-menus.
Status information for the relevant menu can be found
on the display to the right of the menus.
temporary lux Activation of temporary increase in the
hot water temperature. Status information displays “off"
or what length of time of the temporary temperature in-
crease remains.
comfort mode Setting hot water comfort. The status
information displays what mode is selected, "economy",
"normal" or "luxury".
scheduling Scheduling hot water comfort. Status inform-
ation "set" displays if any part of the schedule is active
at present, "holiday setting" displays if vacation setting
is in progress (menu 4.7), otherwise it displays "off".
advanced Setting periodic increase in the hot water
temperature.
Menu 2.1 - temporary lux
Setting range: 3, 6 and 12 hours and mode "off"
Default value: "off"
When hot water requirement has temporarily increased
this menu can be used to select an increase in the hot
water temperature to lux mode for a selectable time.
Caution
If comfort mode "luxury" is selected in menu
2.2 no further increase can be carried out.
The function is activated immediately when a time period
is selected and confirmed using the OK button. The time
to the right displays the remaining time at the selected
setting.
When the time has run out F1345 returns to the mode
set in menu 2.2.
Select “off" to switch off temporary lux .
Menu 2.2 - comfort mode
Setting range: economy, normal, luxury
Default value: normal
The difference between the selectable modes is the
temperature of the hot tap water. Higher temperature
means that the hot water lasts longer.
economy: This mode gives less hot water than the other,
but is more economical. This mode can be used in smaller
households with a small hot water requirement.
normal: Normal mode gives a larger amount of hot water
and is suitable for most households.
luxury: Lux mode gives the greatest possible amount of
hot water. In this mode the immersion heater may be
partially used to heat hot water, which may increase op-
erating costs.
Menu 2.3 - scheduling
What hot water comfort the heat pump is to work with
can be scheduled here for up to two different time peri-
ods per day.
Scheduling is activated/deactivated by ticking/unticking"ac-
tivated". Set times are not affected at deactivation.
If two settings conflict with each other a red exclamation
mark is displayed.
