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 per-
sonal injury, as a result of a system malfunction.
Use original accessories and the stated components for the in-
stallation.
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 with-
stand 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 cir-
cuit.
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 inspec-
tion.
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 incor-
rect function of the equipment.
CARE
Do not use the unit for specialist purposes such as for storing
food, cooling precision instruments, freeze-conservation of anim-
als, plants or art.
This can damage the items.
Dispose of any packaging material correctly.
Any remaining packaging material can cause personal injury as it may
contain nails and wood.
Do not touch any buttons with wet hands.
This can cause electric shocks.
Do not shut off the power supply immediately after operation
has start.
Wait at least 5 minutes, otherwise there is a risk of water leakage or
breakdown.
Do not control the system with the main switch.
This can cause fire or water leakage. In addition, the fan can start un-
expectedly, which can cause 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 mis-
take.
Serial number
The serial number can be found at the bottom right of
the front cover, in the info menu (menu 3.1) and on the
type plate (PZ1).
Serial number
Caution
You need the product's (14 digit) serial number

staller who installed the product or to special
waste stations.
Do not dispose of used products with normal
household waste. It must be disposed of at a
special waste station or dealer who provides this type
of service.
Improper disposal of the product by the user results in
administrative penalties in accordance with current le-
gislation.

System: The climate system that the relevant schedule
relates to is selected here. This alternative is only dis-
played if there is more than one climate system.
Day: Select which day or days of the week the
scheduling is to apply to here. To remove the scheduling
for a particular day, the time for that day must be reset
by setting the start time to the same as the stop time.
If the row "all" is used, all days in the period are set ac-
cording to that row.
Time period: The start and stop time for the selected
day for scheduling are selected here.

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, regard-
less of the outdoor temperature, and thereby energy
efficient operation. It is from these heat curves that the
heat pump’s control computer determines the temper-
ature of the water to the system, the supply temperat-
ure, 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.
Caution
With underfloor heating systems, max flow
line temperature should normally be set to
between 35 and 45 °C.
With underfloor cooling, "min. flow line temp."
must be restricted to prevent condensation.
Check the max temperature for your floor with
your installer/floor supplier.
TIP
Wait 24 hours before making a new setting,
so that the room temperature has time to sta-
bilise.
If it is cold outdoors and the room temperature
is too low, increase the curve slope by one in-
crement.
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 temperat-
ure is too low, increase the curve offset by one
increment.

difference between the desired and actual room temper-
ature) 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 set-
tings can be made for the relevant systems.

This setting option only appears if cooling is
activated in menu 5.2.4.
The degree minute difference for controlling when the
next compressor is to start is set here.
degree minutes cooling
This selection is only available when the connected ac-
cessory itself counts cooling degree minutes.
After a min or max value has been set, the system will
automatically set the real value in relation to the number
of compressors that are running cooling.

Setting range: 5 – 80 °C
cooling (accessory required)
Setting range: 5 – 40 °C
When required, create your own heating or cooling curve
here, by setting the desired supply temperatures for
different outdoor temperatures.
Caution
Curve 0 in menu 1.9.1 must be selected for
own 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. One step is usually enough to change
the room temperature by one degree, but in some cases
several steps may be required.
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 sta-
bilise.
MENU 1.9.9 - NIGHT COOLING (ACCESSORY
REQUIRED)
start temp. exhaust air
Setting range: 20 – 30 °C
Default value: 25 °C
min diff. outdoor-exhaust
Setting range: 3 – 10 °C
Default value: 6 °C
Activate night cooling here.
When the temperature in the house is high and the
outdoor temperature is lower, a cooling effect can be
obtained by forcing the ventilation.
If the temperature difference between the exhaust air
and the outdoor air temperature is greater than the set
value ("min diff. outdoor-exhaust") and the exhaust air
temperature is higher than the set value ("start temp.
exhaust air") run the ventilation at speed 4 until one of
the conditions is no longer met.
Caution
Night cooling can only be activated when house
heating has been deactivated. This is done in
menu 4.2.

** This menu is also set in the slave heat pump's limited
menu system.
Sub-menus
This menu only appears if a water heater is docked to
the heat pump.
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
increase remains.
comfort mode Setting hot water comfort. The status
information displays what mode is selected, "economy",
"normal" or "luxury".
scheduling Scheduling hot water comfort. The status
information "set" appears if you have set scheduling but
it is not currently active, "holiday setting" appears if holi-
day setting is active at the same time as scheduling
(when the holiday function is prioritised), "active" appears
if any part of scheduling is active, otherwise "off" ap-
pears.
advanced Setting periodic increase in the hot water
temperature.
MENU 2.1 - TEMPORARY LUX
Setting range: 3, 6 and 12 hours and mode "off" and
"one time increase"
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 remaining time for the selected setting is shown to
the right.
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 produces less hot water than the
others, but is more economical. This mode can be used
in smaller households with a small hot water require-
ment.
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 increases
operating costs.

scheduling is to apply to here. To remove the scheduling
for a particular day, the time for that day must be reset
by setting the start time to the same as the stop time.
If the row "all" is used, all days in the period are set ac-
cording to that row.
Time period: The start and stop time for the selected
day for scheduling are selected here.
Adjustment: Set the hot water comfort that is to apply
during scheduling here.
Conflict: If two settings conflict with each other, a red
exclamation mark is displayed.
TIP
If you wish to set similar scheduling for every
day of the week start by filling in “all” and then
changing the desired days.
TIP
Set the stop time earlier than the start time so
that the period extends beyond midnight.
Scheduling then stops at the set stop time the
day after.
Scheduling always starts on the date that the
start time is set for.
