Product Description

2 Product description
This is an original manual. This manual may not be translated without the approval of the manufacturer.
Heat pump Compress 7001i/7400i AW is included with the unit AWE 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.
2.1 Type plate · Compress 7001i/7400i AW: The type plate is located on the rear of
the heat pump. · AWE : The type plate is located on the inside unit’s electrical box
inside the front panel.
The type plate contains information on power, part number, serial number and date of manufacture.
2.2 Declaration of conformity The design and operating characteristics of this product comply with the European and national requirements.
The CE marking declares that the product complies with all the applicable EU legislation, which is stipulated by attaching this marking.
The complete text of the Declaration of Conformity is available on the Internet: worcester-bosch.co.uk.
2.3 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.

The heat pump switches off at approx. ­ 20 °C or +35 °C. The indoor unit or an external heat source then take over the heating and DHW heating. The heat pump restarts if the outdoor temperature exceeds roughly ­ 17 °C or falls below +32 °C. In cooling mode the heat pump switches off at roughly +45 °C and restarts at roughly +42 °C.

[1] Evaporator [2] Compressor [3] Condenser [4] Expansion valve
2.4 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.
AWE When the heat pump Compress 7001i/7400i AW is connected to the unit AWE an external DHW cylinder must be connected if the heat pump is to produce hot water. The change between heat and hot water is then controlled via an external 3-way valve. The integrated booster heater in the indoor unit is started if necessary.

2.5 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.

Operation

· 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.
3 Operation
WARNING Material damage from frost! The heating or auxiliary heater may be irreparably damaged by frost. Do not start the indoor unit if there is a possibility of the heating or
auxiliary heater being frozen.
3.1 Control unit The user interface HPC 410 controls max. 4 heating circuits individually in one of the respective control modes: · Outdoor- temp.-compensated
­ the flow temperature is adjusted based on the outside temperature according to an optimised heating curve.
· Outdoor-temp.-compensated with low end1) ­ the flow temperature is adjusted based on the outside temperature according to a simplified heating curve.
For both of the control modes a room controller may be installed in the reference room to allow the influence of the measured and required room temperature. The heating curve is then adjusted accordingly.
The user interface HPC 410 is installed in the appliance and cannot be used as room controller. Ask your contractor for available room controllers.
Rule of thumb for outdoor-temp-compensated control with influence of room temperature: the thermostatic valves in the reference room (the room in which the remote control is installed) must be fully open!

The adjustment ranges, default settings and functional scope may differ from the information in these instructions, depending on the system installed at the site. · If 2 or more heating circuits are installed, settings for different
heating circuits are available and are necessary. · If special system components and modules are installed (e.g.
MS 200 solar module, pool module MP 100), corresponding settings are available and necessary. · If certain types of heat source are installed, additional settings may be available and necessary.
3.1.1 Operation after power failure At electric power failure or periods with disconnected heat source, no settings are lost. The control unit will restart when the power is restored. It is possible that time and date may need to be reset. No other settings are needed.

4.1.1 Check system pressure Check the pressure on the pressure gauge. If the pressure is lower than 0.5 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.
4.1.2 Particle filter The filter prevents particles and contamination from entering the heat pump. Over time, the filter can become blocked and must be cleaned.

To clean the filter, the system does not need to be emptied. The filter and shut-off valve are integrated.
Cleaning the strainer Close the valve (1). Unscrew the cap (manually) (2). Take out the strainer and clean it by running water over it or by
pressure cleaning. Reinstall the strainer. For proper assembly, make sure that the guide
bumps fit into the recesses in the valve.

1. 6 720 805 915-01.1I
   Fig. 7 Cleaning the strainer Screw the cap back on (tighten handtight). Open the valve (4).
   Check the magnetite indicator After installation and startup the magnetite indicator must be checked at more frequent intervals. If a lot of magnetic dirt is clinging to the magnetic bar in the particulate filter and that dirt frequently causes an alarm related to the poor flow (e.g., low or poor flow, high flow supply or HP alarm) an approved magnetite filter must be installed to avoid regular draining of the indicator. The magnetic filter must be installed in addition to the mesh filter and be placed in the secondary circuit after the hydraulic separation. A filter also increases the longevity of components in the heat pump as well as the remaining parts of the heating system. When installing a magnetic filter, consideration should be made for the product specific impact on the pressure drop on the system.
   4.1.3 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 AWE: Contact the installer or dealer.
   4.1.4 Pressure switch
   The pressure switch and the overheat protection are connected in series, triggered alarm or information in the controller means too low pressure in the system or too high temperature in the booster heater.
   If the pressure switch is released it resets itself when the pressure is sufficient in the system.

4.1.5 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.
4.1.6 Checking the safety valves
The safety valves should be checked 1-2 times each a year.
Water is expelled from the safety valve during heat-up. Never close the safety valve.
The safety valve should only let water out if the maximum pressure is exceeded. Contact the installer if water is coming from the safety valve at pressures below 2 bar.
The drainage hose from the safety valve shall be discharged into the sewage / floor well.
4.2 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 Cleaning of the condensation catch pan
4.2.1 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.
4.2.2 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.
Cleaning of the evaporator: Spray detergent on the evaporator fins on the back of the heat pump. Rinse off coatings and detergent with water.

In some regions, washing-up liquid 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 washing-up liquid in a suitable container. Reconnect the condensate tube after cleaning.
4.2.3 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.
If the heat pump has sound insulation, ice can form. In this case there is risk of falling.

4.2.4 Cleaning of the condensation catch pan If the control unit displays the alarm that the heat pump needs to be cleaned, remove the dirt particles and leaves that impair the de-icing function from the condensation catch pan.

Maintenance
WARNING The evaporator’s aluminium fins are thin and sensitive. The fins have sharp edges. Risk of cuts in the event of careless handling. Wear protective gloves on your hands to protect against cuts. Proceed with caution in order not to damage the fins.

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

Technical terms

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: DHW, DHW reduced and Off. 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.
