BUILDING REGULATIONS This appliance must be installed and serviced only by a competent person in accordance with the current: IEE Regulations, Building Regulation, Building Standards (Scotland) (Consolidation), Building Regulations (Northern Ireland), local water by-laws, Health & Safety Document 63S (The Electricity at Work Regulations 1989), IS 813 (Eire) and other local requirements.
Important information Your new Greenstore Combi heat pump represents a new generation of heat pump from Worcester. It contains numerous functions to control the temperature and production of hot water in the house. The Rego 637W control unit is the brains of the heat pump. The Rego 637W includes a control and monitoring function that stores important settings about the heat pump’s operation and maintenance.
How the heat pump works How the heat pump works The heat pump collects stored solar energy The heat pump has been manufactured for easy and reliable use as well as to provide your house with inexpensive and environment friendly heating. The easiest way to describe how a heat pump works is to say it works like a refrigerator, but in reverse. In a refrigerator, heat is moved from the inside to the outside. In a heat pump, heat stored in the ground, rock or water, is moved into the house.
How the heat pump works The heating circuit The collector circuit Heat transfer fluid pump 1 2 3 0ºC 4 +100ºC 0ºC Underfloor heating 6 -3ºC Soil -10ºC 5 Heating system pump Radiator Heat pump Rock Fan-assisted radiator 1 Heat transfer fluid in. The heat pump collects stored solar energy. It contains a heat transfer fluid which is a solution of water and glycol. This antifreeze mixture collects the heat from the earth or rock and is fed into the evaporator.
Component parts of the heat pump Component parts of the heat pump Greenstore Combi Three-way valve The valve switches between heating the heating water and domestic hot water. Electrical connections Connections for the mains supply as well as sensors. Venting nipple The nipple is used to vent the primary water in the hot water cylinder. Control panel The control panel has a back lit menu display with four rows of text information, three buttons and a dial.
Rego 637W Control Rego 637W Control unit The control unit is the brains of the heat pump. It makes sure the heat pump gives the best energy savings. The control unit controls and monitors the heating and hot water supply in your house. The monitoring function is especially important. It shuts down the heat pump in the event of operational abnormalities so that no critical parts are damaged.
Rego 637W Control unit The control unit’s two methods to control the heat pump The control unit uses two different methods to control the heat pump. These two methods are A or B, as below: A: Control with outdoor sensor A sensor is installed outside on a North facing wall of the house. Control with an outdoor sensor means that the heat pump automatically regulates the heating in the house depending on the outdoor temperature.
Control panel Control panel All settings are made on the control panel. It also displays heat production statistics and information about different alarms. When you have made your settings, the control panel makes sure they are saved in the control unit. Controls and status indicators Power switch (ON/OFF) Indicator on: Mains power ON. Indicator flashes: Mains power OFF. Status indicators Operating status Indicator on: The heat pump (compressor) is operational.
Control panel Menu dial The menu dial is used to scroll through the menu display windows. Turn the menu dial clockwise (to the right) to move down through the menus. Turn the menu dial anti-clockwise (to the left) to move up through the menus. You also determine the values of different settings by using the dial. The menu display gives you information and the chance to make settings. You can: Initial menu display Choose different temperature and hot water settings.
Basic functions - Customer level 1 Menu outline for Basic functions (Customer level 1) Rego 637W K1 Note 060822 16:08:15 Tu Heat Info Menu Each menu is numbered in the lower right-hand corner; this indicates which main display it is associated to. Main menu Indoor temperature settings 1 Temp. incr. / decr. Page 15 Temp.
Basic functions - Customer level 1 The heat pump is in standby mode. STANDBY No rad heat required No hotwater required The heat pump is producing hot water. The present temperature and temperature at which the heat pump will stop are shown. Note that the stop temperature is read at the bottom of the hot water cylinder therefore, the domestic hot water is a few degrees warmer in the top of the cylinder. The heat pump and electrical heater are running. HOTWATER MODE Heat pump only Stop temp.
Basic functions - Customer level 1 Change the cur ve slope The heat pump’s production of heat is adjusted by increasing or decreasing the curve slope in the Temp. incr. / decr. menu. This is especially effective in cold weather conditions. Return temperature (ºC) Curve slope (0-10) Cur ve slope: 2-4 Normal setting for floor heating.. 4-6.5 Normal setting for radiators. 7-10 Abnormal high setting. Outdoor temperature (ºC) Curve slope 4 gives a return temperature of +35ºC when it is 0ºC outdoors.
Basic functions - Customer level 1 Fine-tune the heat cur ve The heat curve can also be fine-tuned. Fine-tuning means that the heat curve is offset in parallel. Fine-tuning is done from the Temp. fine-tune menu. The diagram for fine-tuning shows how the dashed line has been offset upwards in parallel. This means the heating has been fine-tuned in a positive direction and the heat pump will be instructed to maintain a higher temperature on the return water at all outdoor temperatures.
Basic functions - Customer level 1 Set the required room temperature If a room sensor is connected to the heat pump the temperature of the room can be set using the Room temperature menu, or by using the Extra functions menu (Customer level 2). To set the room temperature:: 1. Press the Heat button in the initial menu. Note The example describes how to set the required room temperature with the help of a connected room sensor. The range is 10ºC to 30ºC. 2.
