PRE - INSTALLATION 3 PRE - INSTALLATION 3.1 GROUND SOURCE HEAT PUMP OPERATION As the outside temperature gets colder, the heat demand of a house increases and the output of an ground source heat pump will decrease. Eventually it becomes so cold outside that the output of the heat pump alone is not able to heat the building effectively. The Greestore range of ground source heat pumps therefore allows for monoenergetic and bivalent operation.
STANDARD DELIVERY and components used as part of the secondary domestic water system must be approved for use with potable water supplies. This is to certify that the above ranges of products manufactured by Bosch Thermotechnology have been tested and found to comply with: • the requirements of the (Water Fittings) Regulations 1999 for England and Wales, the Water Byelaws 2000, Scotland and the Water Regulations Northern Ireland.
GENERAL 7 ▶ Heat pump installation, energy drilling and collector installation must follow applicable regulations. GENERAL Only a competent person may carry out the installation. The installer must follow applicable rules and regulations and recommendations from the supplier. 7.1 6-11 System are heat pumps designed to be supplemented with an external hot water cylinder e.g. our 280 litre solar compatible.
HEATING, GENERAL 7.10 CAN-BUS TERMINATION 1 Term No Term A method for good ESD protection is a ground-connected bracelet when handling electronics. This bracelet must be put on before opening the screened metal bag/packaging or before exposing an installed board. The bracelet must be worn until the circuit board is enclosed in its screen packaging or closed electric box. Replaced, returned circuit boards must be handled in the same way. 2 6 720 644 816-03.1I Fig.
ENERGY METERING the heat pump and provide the control unit with information about the current room temperature. The signal affects the flow temperature. For example, it falls when the room controller indicates a higher temperature than the one set. Room controllers are used when factors other than the outdoor temperature influence the indoor temperature of the house.

REGULATIONS OUTLINE DRAWINGS FOR THE COLLECTOR HOSE IN THE GROUND AND THROUGH A WALL REGULATIONS The following regulations and requirements must be observed: • The responsible power supply company's local regulations and requirements, including any corresponding special rules • National building regulations • EN 60335 (Electrical appliances and similar utilities - Safety) part 1 (General demands) part 2-40 (Special demands on electrical heat pumps, air conditioners and air dehumidifiers) • EN 12828 (Heati
INSTALLATION After the manifolds and the flow control valves, the coils are connected to a collecting pipe. A filling link, filter and the plastic expansion vessel supplied with the heat pump are connected to the collecting pipe. A pressure relief valve is connected to the outgoing pipe. One circuit at a time is filled with heat transfer fluid. Keep the valves closed in the other loops during the process.
INSTALLATION FILLING UNIT A filling unit is included in the delivery and should be installed close to the collector circuit inlet. COLLECTOR CIRCUIT PUMP Factory setting for the collector circuit pump is max ( Figure 20). The setting may need to be adjusted to achieve the correct delta value ( Chapter 17.4). The value must lie within the grey area. To adjust the value, turn the dial. At cascade connection, make sure that the setting on the collector circuit pump is max.
INSTALLATION 13.4 HEATING SYSTEM 13.7 FLUSHING THE HEATING SYSTEM PARTICLE FILTER (INTEGRATED IN 6-11 SYSTEM) FOLLOW THE GUIDANCE OF BS7593: Treatment of water in domestic hot water central heating and also the flushing guidelines below. A particle filter for the heating system is included in the delivery of 6-11 Combi and should be installed on the connection for the heating system's return line. The particle filter is installed in the return heating pipe to the heat pump ( [E21.V101], chapter 11.2.
INSTALLATION 13.10 REMOVING THE FRONT PANEL 13.11.4 ROOM TEMPERATURE CONTROLLER (ACCESSORY) ▶ Loosen the screws, tilt the front panel outwards and take it off. 1. 2. The room controller will only operate and control the relevant heating circuit. 1. When the room temperature controller is connected and integrated in the system, this is automatically acknowledged during the initial configuration. Requirements for installation location: • If possible, interior wall without draughts or heat radiation.
INSTALLATION ▶ Refill to the correct pressure. Normal pressure is 1.0 – 2.5 bar, but depends on the expansion vessel's pre-pressure and the height of the building. ▶ Shut the heating water filling valve when the correct pressure is reached. ▶ Check all connections for leaks. ▶ Turn the valves on the filling unit so that they are in filling position ( Figure 27). 13.
ELECTRICAL CONNECTIONS ▶ The circuit must be pressurized when venting is complete. Turn the valves on the filling unit to pressure increase position and pressurize the circuit to 2.5 to 3 bar ( Figure 30). Make sure the expansion vessel has an air pocket corresponding to approximately 1/3 of the total volume, by using the de-airing valve on top of the expansion vessel 6 720 641 570-07 .1I Fig.

SETTINGS 20 ▶ Check also that the highest temperature T1 with Underfloor does not exceed the permitted value for the type of floor used. SETTINGS The heat curve forms the basis for set point value calculation of the flow temperature. Most other temperatures for heating that are set refer to room temperature. These values are transformed by the control unit into flow temperature values. 20.1 ROOM TEMPERATURE Press the button in the standard display to open the main menu.
SETTINGS Setting of heat curve If the heat curve has been set too high, the display will show the message Too high heat curve setting. ▶ Change the heat curve setting. A heat curve is set for each circuit. If the room temperature is perceived to be too high or too low in the circuit, it is preferable to adjust the curve. The curve can be changed in different ways.

SETTINGS 20.1.1 SET POINT VALUE The heating circuit's set point value is the temperature of the flow that the heat pump attempts to maintain. Sometimes, the measured actual value fluctuates a bit upward and downward depending on changes in the outdoor temperature or a large hot water demand. The set point value specified by the customer/installer is most often the room temperature, which is recalculated by the control unit into a corresponding flow temperature set point value.
