  • Page 5: For The User

    In this case the control unit is located in the electric boiler. When the heat pump has been installed and started there are a number of points you should check regularly. This may concern an alarm triggering or performing basic maintenance actions.

  • Page 6: How A Heat Pump Works

    In a refrigerator heat is moved from the inside to the outside. In a heat pump the heat, in the outdoor air, is moved into the house. The heat pump is placed on the outside of your house.
  • Page 7 The refrigerant meets the outdoor air in the evaporator (heat exchanger). The air is drawn through the evapora- tor by a fan located on top of the heat pump. The refrigerant, which was previously in a liquid state, will evaporate in this process.

  • Page 8: Component Parts Of The Heat Pump

  • Page 10: Control Unit Rego 800

    Control unit Control unit Rego 800 The control unit makes sure the heat pump gives the best energy savings and that it runs for many years. The control unit controls and monitors the heating and hot water supply in your house. The monitoring function is es- pecially important, it shuts down the heat pump in the event of operational disturbances so that no critical parts are damaged.

  • Page 11: The Control Unit's Operating Modes

    Control unit The control unit’s operating modes When a heat pump is installed, it must be set-up for a specifi c operating mode. An operating mode relates to the heat pump’s working situation which is dependent on the prevailing conditions, for example, whether an electric or oil-fi...

  • Page 12: The Control Unit's Control Method For Heating

    Control with an outdoor sensor is the most common method used by the control unit to control the heat pump. A sensor is mounted on the external wall of the house (the wall that is the coldest and subjected to the least amount of sun).

  • Page 13: Control Panel

    The control unit is controlled via the panel in accordance with your requirements. When the heat pump is combined with 290 A/W, the control panel and control unit are in 290 A/W. When the heat pump is installed with electric cassette or electric/oil- fi...

    65ºC, via the function Extra hot water. A higher water temperature gives more hot water when, for example, several people wish to shower. The heat pump uses the additional heat to increase the temperature to 65ºC.

  • Page 17: Temperatures

    Temperatures There are several different temperature sensors connected to the heating installation. Each sensor plays an important part in the heat pump's daily operations. The current temperatures for the sensors which are most important for controlling heating and hot water production are given under Temperatures.

  • Page 18: Advanced Menu

    Advanced menu Advanced menu The initial menu in the control unit is called Menu. In this menu you will fi nd the functions most frequently used and the ones you have the most benefi t of. In addition, there are extra functions that can be used to affect your heating installation.
