General safety instructions

Application area

• The heat pump may only be used in sealed heating systems according to EN 12828.
• Other uses are not appropriate. Any damage that results from such use is excluded from liability.
• The heat pump must undergo maintenance according to EN1717 4.6.
• Safety of electrical devices for domestic use and similar purposes
• The following requirements apply in accordance with EN 60335-1 in order to prevent hazards from occurring when using electrical appliances:
• “This appliance can be used by children of 8 years and older, as well as by people with reduced physical, sensory or mental capabilities or lacking in experience and knowledge, if they are supervised and have been given instruction in the safe use of the appliance and understand the resulting dangers. Children shall not play with the appliance. Cleaning and user maintenance must not be performed by children without supervision.”
• “If the power cable is damaged, it must be replaced by the manufacturer, its customer service department or a similarly qualified person, so that risks are avoided.”

Danger of fire or explosion of flammable gases

• The product contains the flammable refrigerant R290. If a leak occurs, the refrigerant may form a combustible gas due to mixing with air. There is a risk of fire and explosion.
• A protection zone is defined around the product; see the “Protection zone” chapter.
• Make sure that no sources of ignition are present near the protection zone, especially open fires, surfaces hotter than 370 °C, spray or other gases that could ignite.

Inspection and maintenance
If there is a lack of cleaning, inspection or maintenance, or if these are carried out incorrectly, this may result in material damage and/or personal injury, including possible risk to life.

• Have work carried out only by an approved contractor.
• Do not take off the heat pump cover.
• Do not modify the heat pump or other parts of the heating system.

Room air
The air in the installation room must be free of combustible or chemically aggressive substances.

• Do not use or store combustible or explosive materials (paper, propellants, thinners, paints, etc.) within the vicinity of the appliance.
• Do not use or store corrosive substances (solvents, adhesives, chlorinated cleaning agents, etc.) within the vicinity of the appliance.

Damage caused by frost
The solar system can freeze if it is switched off:

• Observe the notices regarding frost protection.
• Due to the additional functions, e.g. DHW heating or pump anti-seizure protection, the system should always be left on.
• Correct any faults immediately.
• Risk of scalding at the DHW draw-off points
• If DHW temperatures above 60 °C are set or if thermal disinfection is activated, a mixer must be installed. If in doubt, ask your installer.

Product description

• Heat pump AW OR is included with the unit Compress 5800i 12 E in a series of heating pumps that extract energy from the outdoor air to provide water-borne heat and hot water.
• By turning the process over and taking up heat from the water and placing it in the outdoor air, the plant can produce cooling if necessary. However, this requires that the heating system is intended for cooling operation.
• The heating system is controlled by a control unit located in the inside unit. The control unit controls and monitors the system with the help of various settings for heating, cooling,
• hot water and other operations. The monitoring function closes e.g. of the outdoor unit in case of any malfunctions so that no vital parts are damaged.

Protection zone

• The product contains the refrigerant R290 that has a density greater than air. If a leak occurs, the refrigerant could accumulate near the ground. The refrigerant must therefore be prevented from collecting in niches, drains, gaps, other sinks, hollows or depressions in the building.
• No building openings such as light shafts, hatches, valves, open down pipes, cellar entrances, windows, doors, roof vents and roof drainage systems, pump shafts, inlets in sewers, waste water shafts, etc. are permitted within the defined protection zone around the product. The protection zone must not overlap general areas or adjacent plots.
• No sources of ignition such as contactors, lamps or electrical switches are permitted within the protection zone. The defined protection zones are also applicable for installations on pitched roofs, with the addition that no openings to the building and no sources of ignition are allowed below the product.
• No structural changes are allowed in the protection zone that violates the rules mentioned above for the protection zone.

Data plate

• AW OR: The data plate is located on the rear side of the heat pump.
• Compress 5800i 12 M: The data plate is located inside of the indoor unit. For the exact location ( the installation instructions of the appliance).

The data plate contains information on output, item number, serial number and date of manufacture.

Heat pump (outdoor unit)

• The heat pump is inverter operated, which means that it will automatically change the compressor speed to deliver the exact amount of energy required at the moment. The fan is also RPM controlled and will change its speed as needed. This provides the lowest possible energy consumption.
• The speed changes have an effect on the sound emissions, as higher speed results in higher sound emission.

Defrosting

• Ice might form on the evaporator during lower outside temperatures. In case there is enough ice to inhibit the air flow through the evaporator, an automatic defrosting will start. As soon as the ice is gone, the heat pump returns to its normal operation.
• If the outside temperature is above +5 °C the defrosting will be performed alongside continued heat production, however if the temperature is lower, the defrosting is done by ways of a 4-way valve turning the heat medium direction in the circuit so that the hot gas from the compressor melts away the ice. The duration of the defrost cycle depends on the actual outdoor temperature and the amount of frost on the evaporator.

Range for heat pump without booster heater

• In heating mode the heat pump switches off at approx. – 23 °C or +45 °C outdoor temperature. The indoor unit or an external heat source then takes over the heating and domestic hot water production. The heat pump restarts if the outdoor temperature exceeds roughly – 17 °C or falls below +42 °C.
• In cooling mode, the heat pump switches off at roughly +45 °C and restarts at roughly +42 °C.

Compress 5800i 12 E
When heat pump AW OR is connected to indoor unit Compress 5800i 12 E, an external domestic hot water cylinder is required if the purpose of the heat pump is also to produce domestic hot water (DHW). In this case, switching between heating and DHW is managed by an internal 3-way valve. The integrated booster in the indoor unit will turn on if needed.

Indoor unit
The task of the indoor unit is to distribute the heat from the heat pump to the heating system and the hot water cylinder. The circulation pump in the indoor unit module is RPM controlled, and will automatically decrease in speed when demand is low. This decreases energy consumption. When the heating demand is higher during cold outdoor temperatures, an additional heat source – a booster – may be required. This booster heater is integrated, an its on/off is controlled by the user interface in the indoor unit. Please note that when the heat pump is running, the booster heater will only provide the heating output that the heat pump cannot produce itself. When the heat pump is able to provide all the heating needed, the booster is automatically turned off .

Hints on energy saving

• Use the normal heating mode, thus the heating system will use the least energy. Set the desired room temperature according to your personal comfort needs.
•  Open the thermostatic vents fully in all rooms. Increase the temperature setting on the control only when the desired room temperature has not been reached for some time. Close the thermostatic valve in a specific room, only if that room is warmer then the others.
• If there is a room controller installed, this can be used to set the optimal room temperature. Avoid influence of external heating (i.e sunlight or wood stove). Otherwise unwanted fluctuations in the room temperature may occur.
• Avoid placing big objects e.g. a sofa in front of the radiators (minimum 50 cm distance). This will block the circulation of the heated air in the room.
• Do not set a too low temperature for cooling. Cooling will also consume energy.

Vent the room correctly
Open the windows fully for a short period instead of leaving them ajar. Leaving the windows ajar will let the heated air out of the room constantly without increasing the air quality. Close the thermostatic valves or lower the heating setting on the room controller while the room is vented.

Control unit
If a room controller is installed, the thermostatic valves in the reference room (the room in which the remote control is installed) must be fully open!

Maintenance

• DANGER
  • Risk of electric shock.
  • Grave personal injuries may occur.
  • Disconnect the power supply before carrying out maintenance work.

Using the wrong cleaning product may damage the units!
Do not use acid or chlorine based products or products that contain abrasives.

Indoor unit
Carry out the following inspection and maintenance activities a couple of times a year:

• System pressure
• particle filter
• Magnetitefilter
• Humidity in cooling mode
• Pressure-relief valves

1. [1] particle filter
2. [2] Pressure gauge

Check system pressure

• Check the pressure on the pressure gauge. The pressure is also shown in the system overview on the display ( Chapter 2.6.1).
• If the pressure is lower than 0.6 bar, slowly increase the pressure in the heating system by adding water through the filling valve to a maximum of 2 bar.
• Contact your installer or reseller if you are insecure how to perform the filling.

Particle filter

• WARNING
  • Strong magnet!
  • Can be harmful to pacemaker wearers.

Do not clean the filter or check the magnetite indicator if you are a pacemaker wearer.

• The filter prevents particles and contamination from entering the heat pump. Over time, the filter may become blocked and must be cleaned.
• The system does not need to be emptied to clean the filter. The filter is integrated into the shut-off valve.

Cleaning the strainer

• Close the valve (1).
• Unscrew the cap (manually) (2).
• Take out the strainer and clean it with running water over it or by pressure cleaning.
• Check attached debris on the cap’s magnet (3) and clean it.
• Reinstall the strainer (4). For proper assembly, make sure that the guide bumps fit into the recesses in the valve.
• Screw the cap back on (hand tight).
• Open the valve (5).

Check and clean the magnetite filter
Check and clean the magnetite filter 1-2 times a year, but directly after installation and commissioning the filter should be checked and cleaned more frequently. See the instruction that is supplied with the filter for correct procedure.

Overheating protection
Overheating protection is only available in indoor units with integrated booster heater. The overheating protection has to be manually reset if it is triggered.

• To reset the overheating protection on Compress 5800i 12 E:
• Contact the installer or dealer.

Moisture in cooling mode

• NOTICE
  • Insufficient condensate insulation
  • Moist near the components of the heating system.
  • Shut of the heating system and contact retailer/installer if moist or condensate is found near any of the heating system components.

Safety valves
Water is expelled from the safety valve during heat-up. Never close the safety valves.

Check the safety valves function.
The safety valves should only let water out if the maximum pressure is exceeded. Contact the installer if water is coming from the safety valves below the maximum allowed pressure.

Heat pump (outdoor unit)
The following inspection and maintenance steps are carried out several times per year in order that the heat pump’s maximum output will be maintained:

• Housing (casing)
• Cleaning of the evaporator
• Snow and ice

Housing (casing)
Dust and other dirt particles concentrate in the heat pump’s outdoor unit over time.

• Remove dirt and leaves from the heat pump with a brush.
• If required, clean the outside with a damp cloth.
• Spot repair cracks and damage on the casing with anti-corrosive paint.
• Standard car wax can be applied to protect the paint.

Evaporator
Any layers of dust or dirt, for example, deposited on the surface of the evaporator must be removed.

CAUTION

• The aluminium fins are thin and sensitive.
• They can be damaged easily due to careless handling.
• Never use hard objects.
• Never rub the fins directly with a cloth.
• Wear protective gloves.
• Never use water pressure that is too high.

Damage to system due to use of unsuitable cleaning agents!

• Do not use acidic or alkaline cleaning agents or cleaning agents containing chlorine or abrasive products.
• Do not use strong alkaline cleaning agents, e.g. sodium hydroxide.

Cleaning of the evaporator:

• Spray a cleaning agent on the evaporator fins on the back of the heat pump.
• Rinse off coatings and detergent with water.

In some regions, the cleaning agent must not be flushed into gravel beds. If the condensate tube discharges into a gravel bed:

• Remove the flexible condensate tube from the drain pipe prior to cleaning.
• Collect the cleaning agent liquid in a suitable container.
• Reconnect the condensate tube after cleaning.

Snow and ice
In certain geographical regions or during periods of heavy snow, snow can get stuck on the back and the roof of the heat pump. Make sure to clear the snow to prevent icing-up.

• Carefully brush the snow off the fins.
• Clear the snow off the roof.
• Hot water can be used to rinse off the ice.

Moisture can form under the heat pump due to condensate not falling into the condensation catch pan. This is normal and no special action is required.

Faults
Faults can be of different kind and severity, indicated by the colour of the fault icon and the text associated with it. If present, the four digit number in brackets (xxxx) after the text is the fault code.

Display of consumption values in relation to the funding guidelines for federal funding for efficient buildings – individual measures (BEG EM)

• The displayed energy consumption, heat quantities and device efficiency (hereinafter “consumption values”) are calculated from device-specific data and measured values. The consumption values displayed are only an estimate (interpolation).
• In real operation, many different factors influence energy consumption. The specific consumption values are among others influenced by:
  • Installation / execution of the heating system,
  • user behaviour,
  • seasonal environmental conditions,
  • components used.
• The consumption values displayed relate exclusively to the heating appliance. Consumption values of other components of the entire heating system (complete heating system with all its associated components), such as i.e. external heating circulation pumps or valves are not taken into account. The deviations between the displayed and the actual consumption values can therefore be considerable in real operation.
• The representation of the consumption values enables the operator to make a relative comparison of the energy consumption over time. In addition, excess or reduced consumption can also be determined. A use for binding billing purposes is not possible.

Technical terms

• Heat pump (outdoor unit)
  The central heat source. Installed in the open air. Alternative designation: outdoor unit. Contains the cooling circuit. Heated or cooled water is channeled from the outdoor unit to the heat pump module (indoor unit).

• Indoor unit
  Installed in the building and distributes the heat from the outdoor unit to the heating system or the DHW cylinder. Contains the control unit and the pump in the heat transfer medium line for the outdoor unit.

• Heating installation
  Designation for the entire installation, comprising the heat pump, heat pump module, DHW cylinder, heating system and accessories.

• Heating system
  Comprises the heat source, container, radiators, underfloor heating system or fan convectors or a combination of these elements if the heating system is made up of several heating circuits.

• Heat. circ.
  The part of the heating system that distributes the heat throughout the various rooms. Consists of pipework, pump and radiators, heating hoses of the underfloor heating system or fan convectors. Only one of the specified alternatives is possible within a circuit. However, if for example the heating system is equipped with two circuits, radiators can be installed in one and an underfloor heating system installed in the other. Heating circuits can be configured with and without mixers.

• Heating water/domestic hot water
  If domestic hot water is connected to the system, a distinction is made between heating water and domestic hot water. The heating water is channeled to the radiators and the underfloor heating system. Shower and water taps are supplied with domestic hot water.
  If a DHW cylinder is present in the system, the control unit switches between heating and DHW mode so that maximum comfort is achieved. The DHW or heating mode can be prioritised by selecting an option on the control unit.

• Heating circuit without mixer
  In a heating circuit without mixer the temperature in the circuit is controlled purely by the energy from the heat source.

• Heating circuit with mixer
  In a heating circuit with mixer, the mixer mixes return water from the circuit with water from the heat pump. This allows heating circuits with mixer to be operated at a lower temperature than the other heating system, e.g. so that underfloor heating systems that operate at lower temperatures can be separated from radiators that require higher temperatures.

• Mixer
  The mixer is a valve that steadily mixes colder return water with hot water from the heat source in order to achieve a specific temperature. The mixer can be situated in a heating circuit or in the heat pump module for the external auxiliary heater.

• 3-way valve
  The 3-way valve distributes thermal energy to the heating circuits or the DHW cylinder. It has two defined settings so that heating and DHW heating cannot occur at the same time. This is also the most effective operating mode, as the DHW is always heated to a specific temperature, while the heating water temperature is continuously adjusted to the outdoor air temperature in each case.

• External auxiliary heater (extra)
  The external auxiliary heater is a separate heat source which is connected via pipework to the indoor unit. The heat produced in the auxiliary heater is controlled via a mixer. It is therefore also referred to as an auxiliary heater with mixer. The control unit controls the activation and deactivation of the auxiliary heater according to the existing heat energy demand. Heat sources are electric, oil-fired or floor standing gas boilers.
  Heat transfer medium circuit
  The part of the heating system that transports the heat from the outdoor unit to the indoor unit.

• Cooling circuit
  The main part of the outdoor unit that obtains energy from the outdoor air and transfers this as heat to the heat transfer medium circuit. Consists of evaporator, compressor, condenser and expansion valve. The refrigerant circulates in the cooling circuit.

• Evaporator
  Heat exchanger between air and refrigerant. The energy from the air that is drawn in through the evaporator causes the refrigerant to boil and turn to gas as a result.

• Compressor
  Moves the refrigerant through the cooling circuit from the evaporator to the condenser. Increases the pressure of the gaseous refrigerant. The temperature also increases as the pressure increases.

• Condenser
  Heat exchanger between refrigerant in the cooling circuit and water in the heat transfer medium circuit. During the heat transfer, the temperature of the refrigerant falls as it changes into the liquid aggregation state.

• Expansion valve
  Reduces the pressure of the refrigerant after it is discharged from the condenser. The refrigerant is then channeled back to the evaporator where the process starts again.

• Inverter
  Located in the outdoor unit and enables the speed of the compressor to be controlled based on the heat energy demand in each case.

• Setback phase
  A period during the time-controlled operation involving the setback operating mode.
  Time-controlled operation
  The heating system is heated in accordance with the time program and switching between the operating modes occurs automatically.

• Operating phase
  The heating operating phases are: heating and setback. They are depicted by the symbols and .
  The operating phases for DHW heating are: Comfort, Eco and Eco+. A temperature can be set for each operating phase (except for Off).

• Frost protection
  Depending on the type of frost protection selected, the outdoor unit is switched on if the outside temperature or room temperature falls below a certain critical threshold. Frost protection prevents the heating system from freezing up.
  Desired room temperature
  The room temperature to be achieved by the heating system. It can be set individually.

• Default settings
  Values saved permanently on the control unit, which are available at all times and can be reset as necessary.

• Heating phase
  A period during the time-controlled operation involving the heating operating mode.

• Parental lock
  Settings in the standard display and in the menu can only be changed if the parental lock (key block) is switched off.

• Mixer/mixing valve
  Assembly that automatically ensures that DHW can be drawn from the draw-off points at a temperature no higher than the temperature set on the mixing valve.

• Normal Operation
  In normal mode, automatic mode (the heating system time program) is not active and the home is steadily heated at the temperature set for normal mode.

• Reference room
  The room in your home where the remote control is installed is the reference room. The room temperature in this room acts as the control variable for the assigned heating circuit (which can include several rooms or the entire house if only one circuit is present).

• Switching time
  A particular time when the heating temperature, for example, is increased or reduced. A switching time is a component of a time program.
  Temperature during an operating phase
  A temperature that is assigned to an operating phase. The temperature is adjustable. Refer to the explanations about the operating mode.

• Flow temperature
  The temperature that the heating water in the heating circuit retains from the heat source through to the radiators or the underfloor heating system in the room.

• Hot water cylinder
  A DHW cylinder stores large volumes of heated potable water. Sufficient hot water is available at the draw-off points (e.g. water taps) as a result.

• Time program for heating
  This time program ensures automatic switchover between the operating phases at defined switching times.
