A remote control unit (option) can also be used for browsing and changing system
data and error notifications. The remote control unit can also be used as a remote
temperature sensor, providing the control system with room temperature data.
The system settings have been organised into menus, similar to folders on a computer.
In addition, there are various user levels in the system. The visibility of menus or
menu items depends on the user level. To access user levels other than

1.5. Ground source heat pump operating principle
A ground source heat pump is a device that uses heat energy from the Sun that is
absorbed into Earth’s surface.

A. Brine circuit
B. Refrigerant circuit
C. Heating circuit
There are three closed circuits running within, or through, the heat pump:
● brine circuit
● refrigerant circuit
● heating circuit.
The heat pump's operation is based on the vaporisation and condensation of the
refrigerant circulating within the heat pump.
The brine circuit is a circuit for collecting heat energy from the ground. When the brine
enters to the circuit at the evaporator, it is very cold. As it travels along the circuit, it
collects heat energy from the ground or water, which causes the brine temperature
to rise. The brine completes its circuit by returning to the evaporator and releasing
the heat energy into the refrigerant, which circulates between the evaporator and the
condenser.
