Product information
Hydrolution is a complete modern heat pump system that
offers effective technical energy saving and reduced carbon
dioxide emissions. Heat production is safe and economical
with integrated hot water heater, immersion heater, circulation
pump and climate system in the indoor unit.
Function
The heat is retrieved from the outdoor air through outdoor unit,
where the refrigerant circulated in a closed piping system transfers
the heat from the heat source (outdoor air) to indoor unit.
Hydrolution is a system that can produce heating, hot water
and cooling.
This eliminates the need for holes and coils in the ground.
Features of Hydrolution
■Optimal annual heating factor thanks to the inverter
controlled compressor.

The principle during heating can be simplified as follows:
1.The refrigerant in outdoor unit takes the heat from the
outdoor air and is compressed to higher temperature by the
compressor.
2.The hot refrigerant (now in gas state) is routed into indoor unit.
■Outdoor unit with compact dimensions.
3.The refrigerant releases the heat for further distribution in
the system.
■Speed controlled system pump that supplies the heat pump
with suitable system flow.
4.The refrigerant (now in liquid state) is routed back to
outdoor unit and the process is repeated.
■Optimized operating costs. The speed of the compressor is
adjusted according to the demand.
By reversing the entire process, and thereby the refrigerant in
outdoor unit takes the heat from the water and release the heat
to the outdoor air, the heat pump can cool instead if necessary.
■Integrated coil water heater in indoor unit.
■Integrated clock for scheduling extra hot water and
temperature lowering/increasing the supply water temperature.
■Prepared for control of two heating systems.
■Integrated active cooling function.
■Possible to connect external heat sources.
Indoor unit determines when outdoor unit is to work and not to
work, using the collated data from the temperature sensor. In
the event of extra heat demands, indoor unit can connect additional
heat source in the form of the internal immersion heater, or any
connected external heat source.

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 heating 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 medium) to
the temperature required at a certain outdoor temperature. This
occurs automatically on the basis of the collected temperature
values from the outdoor sensor and sensors on the lines to the
radiators (supply water sensors). Extra accessories such as room
sensors, can influence the temperature.
In order to operate the system properly, the correct settings
must be made on the heat pump first, see the section “Default
Heating curve setting”.
The outdoor sensor (mounted on an exterior wall of the house)
senses variations in the outdoor temperature early on, sends the
information to the heat pump control computer and heating
operation is started. It does not have to be cold inside the house
before the control system is activated. As soon as the
temperature drops outside, the temperature of the water to the
radiators (supply temp.) inside the house is increased
automatically.
The heat pumps flow temperature (menu 2.0) will hover around
the theoretical required value, which is in brackets on the
display.
Temperature of the heating system
The temperature of the heating system in relation to the
outdoor temperature can be determined by you by selecting a
heat curve and 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 required
operating mode.
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 electric heater is only used for anti-freeze if it is deactivated
in the menu system for all operating modes.
There are different operating modes to choose:
10
1. “Auto”
Indoor unit automatically selects the operating mode by
taking the outdoor temperature into account. This means
that the operating mode switches between "Heating" and
“Hot water”.
The circulation pump is permitted to operate when there is
a need.
2. “AutoC”*
Indoor unit selects operating mode automatically (cooling
can also be selected now) by the outdoor temperature. This
means that the operating mode switches between
“Heating”, “Cooling” and “Hot water”.
The circulation pump is permitted to operate when there is
a need.
3. Heating
Only heating and hot water mode.
The circulation pump is in operation the entire time.
Electirc heater is energized if necessary.
4. Cooling*
Heat pump is used for cooling only if electric heater use is
allowed. Otherwise, it is used for both cooling and hot water.
The circulation pump is in operation the entire time.
5. Hot water
Only hot water is produced.
Only the compressor is operational.
6. Add. Heat only
Heat pump is not operational. The function is activated/
deactivated by pressing in the “operating mode button” for
7 seconds.
* To use the cooling functions, the system must be designed 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 to increase or anticlockwise to lower. One line
approximately represents 1 degree change in room temperature.
NOTE
An increase in the room temperature may be inhibited
by the radiator or underfloor heating thermostats, if so
these must be set at 0.
Comfort setting heating
Default Heating curve setting
Setting with diagrams
The basic heating is set using menu 2.1.2 and with the “Heating
curve offset” knob.
The diagram shows the relation between the outdoor temperature
in the area and the target supply water temperature of the heating
system. This is set under menu 2.1.2, “Heating curve”. Limitations,
which are not in the diagrams, can be set in the control system’s
permitted min and max temperatures. (See menu 2.1.4 and 2.3 as
well as 3.3 and 3.4)
If the room temperature does not reach the target, readjustment
may be necessary.
If you do not know the correct settings, use the basic data from
the automatic heating control system diagram on the right.

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 heater is energized until the water temperature
reaches the stop temperature (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.

Hydrolution requires minimal maintenance after commissioning.
Hydrolution 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 display.
Checking the safety valves in indoor unit
Indoor unit has been equipped with a safety valve for the water
heater as well as a safety valve for the climate system by the
installer.
For HT30, a safety relief valve is supplied with tank unit and
the valve is installed to water pipe by installer.

“ Extra hot water” usually means that the electric heater
is activated regardless of Allow add heat setting (menu
8.2.1) 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 extra hot water operation is selected
in menu 1.7. Menu 1.8 shows when the next extra hot
water operation is due.
The increased temperature is maintained by the
electric heater for one hour.
2. Schedule time based extra hot water
The start and stop times for the day of the week when
the extra hot water operation is required are set in the
sub menus to menu 7.4.0.
The increased temperature is maintained by the
electric heater for the selected period.
3. Temporary extra hot water
Extra hot water operation starts when Extra hot water
button is pressed, and it is kept for 3 hours. The
operation is cancelled when the button is pressed

Maintenance
The climate system’s safety valve (FL2) must be completely
sealed. Checks must be carried out regularly as follows:
■Open the valve.
outdoor unit coming into contact with alkaline cleaning agents.
!
WARNING!
Rotating fan
■Check that water flows through the valve. If this does not
happen, replace the safety valve.
■Close the valve again.
■The heating system may need to be refilled after checking
the safety valve, see the section “Filling the heating
system”.
Hot water heater 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 heater to replace the hot water, expands when
heated causing the pressure to rise and the safety valve to open.
Also check the water heater safety valve regularly. The
appearance and location of the safety valve differs between
different installations. Contact your installer for information.
Pressure gauge in indoor unit
The working range of the heating system is normally 0.5 – 1.5
bar when the system is closed. Check this on the pressure
gauge (BP5).
Emptying the hot water heater
The water heater is of the coil type and is drained using the
siphon principle. This can be done either via the drain valve on
the incoming cold water pipe or by inserting a hose into the
cold water connection.
Emptying the vessel
Contact your installer if the vessel in indoor unit needs
emptying.
Maintenance of outdoor unit
Outdoor unit is equipped with control and monitoring
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 outdoor unit. 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 outdoor unit
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 outdoor unit. Prevent

Saving tips
Your Hydrolution produces heat and hot water according to
your needs. It also attempts to carry out all requirements with
all available “aids” from the control settings 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 insulation 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 heating system, which the heat pump wants to
compensate with increased temperatures. It then works harder
and consumes more electrical energy.

Dealing with comfort disruption
The phenomena mentioned below is not malfunction.
The air conditioning system
sounds as if water is
draining from it.
Sounds of rustling or
gurgling may be heard from
a stopped indoor unit.
The air conditioning system
cannot start operating again
immediately after stopping.
The outdoor unit discharges
water or steam during
heating operation.
The outdoor unit fan is not
running even when the
system is in operation.
Sounds of rustling or gurgling may be heard when the operation is started, when the compressor is
activated/deactivated during operation, or when the operation is stopped. These are the sounds of the
refrigerant flowing through the system.
These sounds can be heard when the air conditioning system is performing automatic control.
Outdoor unit does not restart during the first 3 minutes after stopping operation. This is because a
circuit for protecting the compressor is activated (the fan is operating during this period).
Water or steam is discharge during defrosting operation which removes frost built up on the surface of
the heat exchanger in the outdoor unit in heating mode.
The fan speed is automatically controlled according to the ambient temperature. It may be stopped in
high ambient temperature in case of heating, and in low ambient temperature in case of cooling. Also,
the fan is stopped during defrosting operation.
REQUESTS
Hissing sounds are heard
when the operation is
stopped or during defrost
operation.
The fan will suddenly begin to operate even if it is stopped. Do not insert finger and/or stick.
These sounds are generated when the refrigerant valve inside the air conditioning system is activated.
Operating mode “Add. heat only”
In the event of malfunctions that cause a low indoor temperature,
you can normally activate “Add. heat only” in indoor unit, which
means that heating only occurs with the immersion heater.
Activate the mode by holding in the operating mode button
for 7 seconds.
Note that this is only a temporary solution, as heating with the
immersion heater does not make any savings.
Emergency mode
Emergency mode is activated by setting the switch to “
”.
It is used when the control system and thereby operating mode
“Add. heat only” do not function as they should. Emergency
mode is activated by setting switch (SF1) to “
”.
The following applies in emergency mode:
■The front panel is not lit and the control computer in
indoor unit is not connected.
■Outdoor unit is off and only the circulation pump and
immersion heater in indoor unit are active.
■An electrical step of 4 kW is connected. The immersion
heater is controlled by a separate thermostat (BT30).
■The automatic heating control system is not operational, so
manual shunt operation is required. Call installer.
