Page 6: This Is How Your Heat Pump Works
This is how your heat pump works: Heat pump technology The compressor, which is driven by an electric motor, forces the refrigerant into the heat pump condenser as a gas at about 100°C. The gas and the water from the radiator system pass through the condenser, which is a fully-welded stainless steel heat exchanger. -

Page 9: Principle
Principle Principle of heating and hot water control Your heat pump is fitted with a Rego600 control unit to guarantee you maximum savings and many years of service. The unit, which has advanced monitoring functions, controls the heating and hot water in your home. -
Page 10: Controls
Controls The control unit operates the heat pump in three ways. We call them Curve Control, Room Sensor and Fixed Temperature. Below follows a brief description. Curve control (operating modes A and B) This is the most common mode and is also the factory setting. This means that the heat pump adjusts the heat in the house based on the outdoor temperature so that the radiator temperature increases as the outdoor temperature reduces. -
Page 11: Control Panel
Control panel Control panel buttons and displays The control panel is the heart of your heat pump installation. From the control panel, instructions are sent to the Rego600 control unit, which ensures that the house is uniformly heated. All settings are carried out here and the display shows the settings that have been set. -
Page 12: How To Use The Control Panel
How to use the control panel With three buttons and a knob you can navigate to the various displays for settings and readings. The last line at the bottom of the display contains information about the functions of the buttons in the current display. -
