The Connection setting determines which method is used. This option, in turn, allows you to select the equipment installed in the circuit.

  • Page 32: Heating Circuits 2 And 3

    Relative pressure control When the flow rate (demand for heating) is reduced, the system will reduce the pressure produced by the pump (i.e. the head of the pump). This control mode is suitable for systems where most of the pressure loss can be attributed to a common trunk line (distribution line with branches) shared by two or more heating circuits.

  • Page 33: Commissioning

    4 Commissioning 4.1 General The heat pump’s automation system is operated with an app installed in a smartphone or tablet. This app is used to connect to the heat pump’s built-in data hub. The unit is supplied with a wireless touch screen preinstalled with the app and with the connection already configured.

  • Page 35 Heating Buffer not used The heat pump is connected directly to the building’s heating system without a buffer tank. The configuration may include a flow-through water tank, but not a buffer tank regulated by the heat pump. Connection Buffer in use The heat pump is connected to a buffer tank which is regulated by the heat pump.
  • Page 36 → ADDITIONAL HEATING An electric immersion heater (in-line heater) operates in the same manner as the compressor and uses the same setpoint values. The heater switches on and off (and transitions between higher and lower power stages) with a delay. Condenser flow pipe The condenser flow line includes an in-line heater (electric immersion heater).
  • Page 37 → ADDITIONAL HEATING Freezing protection only The electric immersion heater will be switched on only when heating water temperature falls below 5 °C. The freezing protection function monitors the temperature in the condenser, buffer tank, and the heating circuits. Once the temperature exceeds 10 °C, the immersion heater will be switched off.
  • Page 38 → Additional heating If any of the settings specified below have been selected, the system can switch on the electric immersion heater during DHW heating (as long as the legionella function has been enabled) when the compressor reaches the bounds of its operating envelope and is consequently switched off.
  • Page 39 Start heatpump Start the heat pump either using this option or later from the Service menu. The heat pump is switched off. Used Operating mode The heat pump is switched on. Additional heater only Only the unit’s internal electric immersion heater is used for heating. The compressor and the brine circuit are not in use.

  • Page 40: Operation

    5 Operation 5.1 Heat pump operation The system’s connection diagrams are provided as a separate document. The heat pump collects heat from the fluid in the brine circuit and releases the heat collected through a condenser and into heating water. In addition to the heat pump itself, CUBE heat pump units include an in-line heater for supplementary and backup heating.
  • Page 41 determines when heating starts (instead of the flow water temperature). Whenever the building’s domestic hot water needs heating, space heating will be suspended until domestic hot water has been heated to a sufficient temperature. Domestic hot water tank heating will start when the DHW tank temperature (minus the switching difference) falls below the domestic hot water target temperature.

  • Page 42: Technical Data

    6 Technical data 6.1 Technical data The performance between different units may vary. This variation is due to a wide number of factors, such as the properties of the fluids used in the circuits, fouling of the heat transfer surfaces in the condenser and evaporator circuit, flow rates, individual differences between compressors (standard EN 12900) as well as refrigerant circuit charge and adjustments made to the refrigerant circuit during installation.
