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.
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.
This eliminates the need for holes and coils in the ground.
Features of Hydrolution
■ Op timal annua l h eating fa ctor thanks to the inverter controlled compressor.
■ Outdoor unit with compact dimensions.
■ Speed controlled system pump that supplies the heat pump with suitable system ow.
■ Optimized operating costs. The speed of the compressor is adjusted according to the demand.
■ Integrated coil water heater in indoor unit.
■ Integr ated clock for sch eduling ext ra h ot w ater 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.
Principle of operation Hydrolution
Function
Hydrolution is a system that can produce heating, hot water and cooling.
The principle during heating can be simplied 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.
3. The refrigerant releases the heat for further distribution in
the system.
4. The refrigerant (now in liquid state) is routed back to outdoor unit and the process is repeated.
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.
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 sufcient 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 oor 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 inuence the temperature.
In order to operate the system properly, the correct settings must be made on the heat pump rst, 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 be f ore t h e cont rol sy s tem i s act i vated . A s soon as t h e temperature drops outside, the temperature of the water to the ra d iators (supp l y temp. ) insi d e the house is incr e ased
automatically.
The heat pumps ow 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:
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 th a t th e operatin g mo d e sw itches be t w e e n “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 circ ulation 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 underoor heating thermostats, if so
these must be set at 0.
