General
SPLIT is a system for heating, cooling and producing hot water for small houses. The system consists of an outdoor module
(L8 SPLIT/L12 SPLIT), which utilises the energy in the outdoor air and sends it to the indoor module (HM 8-12 SPLIT), which
takes care of the regulation and heat distribution in the house.
In order to gain the greatest benefit from the SPLIT system, please refer to the 'For Home Owners' chapter within this In-
stallation and Maintenance Manual.

Information about the installation
Product information
SPLIT is a complete modern heat pump system that offers
effective energy saving and reduced carbon dioxide
emissions.
The heat is retrieved from the outdoor air by an outdoor
module (L8 SPLIT/L12 SPLIT), where the refrigerant, which
circulates in a closed system, transfers the heat from the
heat source (outdoor air) to the indoor module (HM 8-12
SPLIT). This eliminates the need for boreholes and coils in
the ground.
Features of SPLIT
■Optimal annual heating factor thanks to the inverter
controlled compressor.
■Outdoor unit with compact dimensions.
■Speed controlled circulation pump.
■Optimized operating costs. The speed of the compressor
is adjusted according to the demand.
■Supplemented with the tanks EHZK 90 SPLIT, WWS 300
SPLIT or WWS 500 SPLIT for the indoor module HM 8-12
SPLIT and outdoor module, L8 SPLIT or L12 SPLIT.
■Integrated clock for scheduling extra hot water and
temperature lowering/increasing the flow line temper-
ature.
■Prepared for control of two climate systems.
■Integrated active cooling function.
■Possible to connect external heat sources.

Function
SPLIT is a system that can produce heating, hot water and
cooling.
The principle during heating can be simplified as follows:
1. The refrigerant in L8 SPLIT/L12 SPLIT retrieves heat
from the outdoor air then compresses it, which in-
creases the temperature further.
2. The hot refrigerant (now in gas state) is routed into
HM 8-12 SPLIT.
3. The refrigerant releases the heat for further distribu-
tion in the system.
4. The refrigerant (now in liquid state) is routed back to
L8 SPLIT/L12 SPLIT and the process is repeated.
By reversing the process, thereby allowing the refrigerant
in L8 SPLIT/L12 SPLIT to retrieve the heat from the water
and release it into the outdoor air, the heat pump can, if
necessary, cool instead.
HM 8-12 SPLIT determines when L8 SPLIT/L12 SPLIT is to
work and not to work, using the collated data from the
temperature sensor. In the event of extra heat demands,
HM 8-12 SPLIT can connect additional heat in the form of
the internal immersion heater, or any connected external
addition.

How to use the front panel
All the most common settings are made from the panel
as well as control computer instructions such as comfort
etc. that you require the heat pump system to fulfil.
In order for the installation to be used optimally, certain
basic settings must have been made (see page 9). In ad-
dition the installation in general must be carried out ac-
cording to the instructions and manufacturer's recommend-
ations.
Menu 1.0 (temperature in the water heater) is normally
shown on the display.
The plus and minus buttons and the enter button
are used to scroll through the menu system as well
as to change the set value in some menus.
Menu types
Control is divided into different menu types depending
on how ”deep” into the controls you need to go.
■Normal [N]: The settings you as a customer often
need.
■Extended [U]: Shows all detailed menus except the
service menus.
■Service [S]: Shows all menus.
The menu type is changed from menu 8.1.1
Quick movement

For Home Owners
Front panel, indoor module

Comfort setting heating
General
The indoor temperature depends on several factors.
■Sunlight and heat emissions from people and household
machines are normally sufficient to keep the house warm
during the warmer parts of the year.
■When it gets colder outside, the climate system must be
started. The colder it is outside, the warmer radiators
and under floor heating systems must be.
Controlling heat production
Normally, the heat pump heats the water (heating medi-
um) to the temperature required at a certain outdoor
temperature. This occurs automatically on the basis of the
collected temperature values from the outdoor temperat-
ure sensor and sensors on the lines to the climate system
(flow line sensors). Extra accessories such as room temper-
ature sensors, can influence the temperature.
However, the correct default settings must be made on
the heat pump first, see the section “Default settings”.
The temperature information that the outdoor sensor
(mounted on an exterior wall of the house) sends to the
heat pump’s control computer senses variations in the
outdoor temperature early on. It does not have to be cold
inside the house before the control system is activated, as
soon as the average outdoor temperature drops outside,
the temperature of the water to the climate system (supply
temp.) inside the house is increased automatically.
The heat pump's supply temperature (menu 2.0) will hover
around the theoretical required value, which is in brackets
on the display.
Temperature of the climate system
The temperature of the climate system in relation to the
outdoor temperature can be modified by using the "Offset
heating curve” knob on the heat pump’s front panel.
Operating status
The “Operating mode” button is used to set the re-
quired operating mode with regard to permitting/block-
ing the circulation pump and additional energy.
The change does not need to be confirmed with the
enter button.
The current operating mode is shown on the front panel
display when the button is pressed and the mode changes
when you continue to press the button.
The display returns to the normal display mode once the
enter button is pressed.
The addition is only used for anti-freeze mode, if it is deac-
tivated in the menu system. This applies to all operating
modes.
The different operating modes are:
1. ”Auto”
■HM 8-12 SPLIT automatically selects the operating
mode by taking the outdoor temperature into ac-
count. This means that the operating mode switches
between "Heating" and "Hot water". Current oper-
ating mode is shown within brackets.
■The circulation pump is permitted to operate when
there is a need.
2. ”AutoK”*
■HM 8-12 SPLIT selects operating mode automatic
(cooling can also be selected now) with regard to
the outdoor temperature. This means that the oper-
ating mode switches between "Heating", "Cooling"
and "Hot water".
■The circulation pump is permitted to operate when
there is a need.
3. "Heat" / "Heat addition"
■Only heating and cooling produced.
■The circulation pump is in operation the entire time.
■If "Heat addition" is shown the addition is permitted
to operate if necessary.
4. "Cooling"* / "Super cooling"
■If addition is permitted, "Super cooling" is displayed.
The compressor then only runs in cooling mode.
Otherwise, the mode switches to cooling or produ-
cing hot water.
■The circulation pump is in operation the entire time.
■Hot water is only produced by the immersion heater.
5. "Hot water"
■Only hot water is produced.
■Only the compressor is operational.
6. ”Add. heat only”
■Compressor blocked. The function is activated by
pressing in the ”operating mode button” for 7
seconds.
7. Deactivate the function by pressing the "Operating
mode" button for 7 seconds once again.
* To use the cooling functions, the system must be con-
structed to withstand low temperatures and "Cooling"
must be activated in menu 9.3.3.
Changing the room temperature manually
If you want to temporarily or permanently increase or
lower the indoor temperature turn the ”Offset heating
curve” knob clockwise or anticlockwise. One line approx-
imately represents a 1 degree change in room temperat-
ure.
NOTE
An increase in the room temperature may be inhib-
ited by the radiator or underfloor heating thermo-
stats, if so these must be turned up.

For Home Owners
Comfort setting heating

Default setting
The basic heating is set using menu 2.1.2 and with the
“Offset, heating curve” knob.
If the required room temperature is not obtained, readjust-
ment may be necessary.
If you do not know the correct settings use the basic data
from the automatic heating control system diagram op-
posite.

General
The condition in order for cooling to be activated is that
"On" is selected in menu 9.3.3 Cooling system.
NOTE
The climate system must manage cooling operation.
Settings must be made by the installer when commis-
sioning the system.
If a room sensor is connected, it starts and stops cooling
together with the outdoor temperature. The lowest current
supply temperature is set in menu 2.2.4.
Cooling operated from the outdoor sensor in
operating mode AutoK
If the cooling system is set to "On" in menu 9.3.3 and the
outdoor temperature is greater or equivalent to the set
start temperature for cooling in menu 8.2.4, cooling starts.
Cooling stops when the outdoor temperature drops below
the set value minus the set value in menu 8.2.5.
The current supply line temperature is determined from
the selected cooling curve in menu 2.2.2 and the offset
for cooling curve, menu 2.2.1. Limitations, which are not
in the diagram, are included in the control system's permit-
ted min temperature.
NOTE
HM 8-12 SPLIT is condensation insulated for cooling
operation down to a supply temperature of + 7 °C.

Comfort setting hot water
The water heaters are coil models and are heated by circu-
lating water, which is heated by the heat pump.
During “normal” consumption it is enough to run the heat
pump’s compressor to supply the different tapping points
of the house with hot water. The temperature of the hot
water in the water heater then varies between the set
values.
Under section 1.0 [N] Hot water temp. on page 53 there
is a complete description of menu settings for hot water
temperatures.

Prioritizing
If the water within the water heater requires heating, the
heat pump prioritises this and shifts to hot water mode
with the entire heat pump output.
In this mode, there is no heating or cooling.
Prioritizing can be affected via settings in the front panel.
See "1.0 [N] Hot water temp." on page 53.
Extra Hot Water
In all ”Extra hot water” functions, the temperature of the
hot water increases temporarily. The temperature is first
increased to an adjustable level by the compressor (menu
1.5) and then the electric additional heat increases until
the stop temperature is reached (menu 1.4).
Temporary ”Extra hot water” is activated manually, whilst
time based extra hot water is activated using the settings
made in the control computer.
When:
■”A” appears above the

NOTE
”Extra hot water” usually means that the electrical
addition has been activated and therefore increases
the electrical consumption.
”Extra hot water” can be activated in three different
ways:
1. Periodic time based extra hot water
■Interval between increases is selected in menu 1.7.
Menu 1.8 shows when the next increase is due.
■The increased temperature is maintained by the
electrical addition for one hour.
2. Schedule time based extra hot water
■The start and stop times for the day of the week that
the increase is required are set in the sub menus for
menu 7.4.0.
■The increased temperature is maintained by the
electrical addition for the selected period.
3. Temporary extra hot water
■The current ”extra hot water” mode is shown on the
display (A) when the button is pressed and by
pressing the button again the mode changes
between 3 hours and standby mode.
■The increased temperature is maintained by the
electrical addition until the period of time has ex-
pired.

Maintenance
HM 8-12 SPLIT and L8 SPLIT/L12 SPLIT require minimal
maintenance after commissioning.
SPLIT contains many components and is why monitoring
functions are integrated to help you.
If something abnormal occurs, a message appears about
malfunctions in the form of different ”alarm” texts in dis-
play.
Checking the safety valves
The installation has been equipped with a safety valve for
the water heater as well as a safety valve for the climate
system by the installer.
The climate system's safety valve
EHZK 90 SPLIT

The climate system's safety valve (FL2) is close to EHZK 90
SPLIT or by the hot water tank. See illustration.
VVS 300 SPLIT/VVS 500 SPLIT
LEK
LEK
BP5
FL2
The climate system's safety valve (FL2) must be completely
sealed. Checks must be carried out regularly as follows:
■Open the valve.
■Check that water flows through the valve. If this does
not happen, replace the safety valve.
■Close the valve again.
■The climate system may need to be refilled after checking
the safety valve, see the section “Filling the climate sys-
tem”. Contact your installer for refilling the climate sys-
tem.
Safety valve domestic water
The safety valve for domestic water sometimes releases a
little water after hot water has been tapped. This is be-
cause the cold water, which enters the heater to replace
the hot water, expands when heated causing the pressure
to rise and the safety valve to open.
Also check the safety valve for domestic water regularly.
The appearance and location of the safety valve differs
between different installations. Follow the cold water pipe
to locate the safety valve. Contact your installer for inform-
ation.
Pressure gauge in EHZK 90 SPLIT, WWS 300
SPLIT, WWS 500 SPLIT
The working range of the climate system is normally 0.5 –
1.5 bar when the system is closed, depending on the height
of the system. Check this on the pressure gauge (BP5).

Maintenance

Emptying the coil in the water heater
The water heater is of the coil type and the pressure in the
domestic coil can be released by closing off the incoming
water and opening the hot water tap. However, some
water may remain in the domestic coil. Drain by removing
the cold water connection XL3 on the water heater.
Emptying the vessel
Contact your installer if the vessel in EHZK 90 SPLIT, WWS
300 SPLIT, WWS 500 SPLIT needs emptying.
Maintenance of L8 SPLIT/L12 SPLIT
L8 SPLIT/L12 SPLIT is equipped with control and monitor-
ing equipment, however some exterior maintenance is
still necessary.
Make regular checks throughout the year that the inlet
grille is not clogged by leaves, snow or anything else.
During the cold months of the year, check to make sure
that there isn't a build up of ice or frost under L8 SPLIT/L12
SPLIT. Strong wind combined with heavy snowfall can
block the intake and exhaust air grilles. Make sure that
there is no snow on the grilles.
Also check that the condensation water drain under L8
SPLIT/L12 SPLIT is not blocked.
If necessary the outer casing can be cleaned using a damp
cloth. Care must be exercised so that the heat pump is not
scratched when cleaning. Avoid spraying water into the
grilles or the sides so that water penetrates into L8
SPLIT/L12 SPLIT. Prevent L8 SPLIT/L12 SPLIT coming into
contact with alkaline cleaning agents.
!
WARNING!
Rotating fan in L8 SPLIT/L12 SPLIT.
Saving tips
Your SPLIT installation produces heat and hot water ac-
cording to your needs. It also attempts to carry out all re-
quirements with all available ”aids” from the control set-
tings made.
The indoor temperature is naturally affected by the energy
consumption. Therefore, take care not to set a temperature
higher than necessary.
Other known factors that affect the energy consumption
are, for example, hot water consumption and the insula-
tion level of the house, as well as the level of comfort you
require.
Also remember:
■Open the thermostat valves completely (except in the
rooms that are to be kept cooler for various reasons, e.g.
bedrooms).
Thermostat valves in the radiators and floor loops can
negatively affect the energy consumption. They slow the
flow in the climate system, which the heat pump wants to
compensate with increased temperatures. It then works
harder and consumes more electrical energy.
