Safety precautions SAFETY PRECAUTIONS Please read these “SAFETY PRECAUTIONS” before starting to use this product and use the product appropriately according to the instructions. The precautions provided here are classified into “ DANGER” and “ CAUTION”. The “ DANGER” sections describe potentially hazardous situations that may lead to serious outcomes such as death and sericus injuries if the product is mishandled.
Safety precautions OPERATION PRECAUTIONS DANGER Do not expose yourself directly to radiator or any other heating device for a long time. It may cause low temperture burn injury. Do not set water temperature too high when under-floor heating application is used. It may cause low temperature burn injury. Do not expose yourself directly to cooled air flow for a long time or cool too much. It may be cause of deconditioning or health disorder.
Safety precautions When the unit isn’t used for a longterm, cut off the power. The accumulation of dirt may lead to heat generation or fire. But, before resuming the operation, turn on the unit for six hours beforehand to save harmless. Do not place any object around the outdoor unit, nor allow fallen leaves to pile up. Fallen leaves may induce insects and worms in them, and they may lead to failure, ignition or smoking by touching electric components.
Safety precautions PRECAUTIONS FOR RELOCATION OR REPAIRING CAUTION Never perform any modification. Contact your dealer for repairing. Improper repairing may lead to water leakage, electric shock or fire. Normally the refrigerant does not leak. But if it leaks and contacts fire such as fan heater, space heater or cooking heater, it may produce toxic chemicals. When repairing refrigerant leakage, determine the service with the service staff that the repair has been finished without fault.
General General Hydrolution is a system for heating, cooling and producing hot water for small houses. The system consists of an outdoor nuit, which utilises the energy in the outdoor air and sends it to the indoor unit, which takes care of the regulation and heat distribution in the house. In order to get the greatest benefit from the system Hydrolution you should read through the User's Manual. Hydrolution is a quality system offering a long service life and reliable operation.
Information about the installation Information about the installation Principle of operation Hydrolution 3 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.

Front panel, indoor unit How to use the front panel All the most common settings are made from the panel such as comfort etc. that you expect from the heat pump system to fulfil. In order to make full use of it, certain basic settings must have been made (see page 11) and the installation in general is carried out according to the instructions. Menu 1.0 (the temperature in the water heater) is normally shown on the display.
Comfort setting heating 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 heating system must be started. The colder it is outside, the warmer radiators and under floor heating systems must be.
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.
Comfort setting heating Readjusting the default settings Comfort setting with room sensor If the room temperature does not reach the target, readjustment may be necessary. If MH-RG10 is installed, operation mode is chosen not only by outdoor temperature but also by room temperature. Cold weather conditions Upper limit of the outdoor temperature to operate in Heating mode can be set in menu 8.2.3 Stop temp Heating.
Comfort setting cooling Comfort setting cooling General In the default setting, cooling operation is not allowed. In order to activate, change the setting on the menu 9.3.3 Cooling system to “On”. NOTE The climate system must manage cooling operation. Setting must be made by the installer when commissioning the system. Settings must be made by the installer when commissioning the system. If a room sensor is connected, it starts and stops cooling based on both the room and the outdoor temperature.
Comfort setting hot water Comfort setting hot water MT500 The integrated water heater is a coil model and is heated by circulating water, which is heated by the heat pump. Under section 1.0 [N] Hot water temp. on page 25 there is a complete description of menu settings for hot water temperatures.
Comfort setting hot water / Maintenance Maintenance 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.
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”.
Dealing with comfort disruption Dealing with comfort disruption Use the following list to find and remedy any heating or hot water problems. Symptom Low hot water temperature or a lack of hot water Low room temperature. Cause Circuit or main MCB tripped. Action Check and replace blown fuses. Heat pump and immersion heater do not heat. Check and replace any blown circuit and main fuses. Possible earth circuit-breaker tripped.
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.
Alarm indications Alarm indications Different types of alarms There are many monitoring functions integrated in Hydrolution. To alert you to any malfunctions, the control computer transmits alarm signals that can be read from the front panel display. What happens in the event of an alarm? ■ The background lighting in the display starts flashing and the status lamp lights red. ■ Some alarms change operating mode to “Add. heat only.
