Page 12: How It Works And Its Proper Use
. How it works and its proper use . The principle of the heat pump function The basic prerequisite for the operation of a heat pump is a heat transfer medium that has suitable properties for changing the state of matter at a given pressure and temperature. All these basic components are outlined in the gure below - Principle diagram of the heat pump function. -
Page 13: Low Temperature Heating System
.. Low temperature heating system An example of a low temperature heating system is: • oor heating • ceiling heating / cooling • wall heating Large area radiant systems are most suitable for use with a heat pump. A heat pump is most effective with these systems and its lifetime is higher. -

. Object The right side of the screen (g. .6 p. ) is reserved for navigation. Use the buttons ntext to browse through each section window. There is a scroll bar next to the arrows to indicate which screen of the section is currently being displayed. This way of navigation is common to all sections. Activating results in that heating / cooling of the object runs only at times of low tariff. - Page 20 The speed of reaction to temperature changes is related to the intervention size allowed (the volume of the pre- set coefcient). Higher coefcient means faster reaction, but too high a value can cause unpleasant temperature uctuations. Item shows the current calculated output water temperature.

The item enables to lower the output temperature of the heating water.In the settings (g. ?? p. ), two time intervals are available for each day of the week. Click the orange rectangles to set the desired times. The heating water temperature will not be affected at the selected time intervals. Outside these time periods, the attenuation is active and the heating water temperature is reduced by the value set in the last window of the attenuation timing program. - Page 23 If item is activated (orange), it means that once a week on Friday starting from midnight, heating of hot water in the tank by the electric heater is on, and it turns off after reaching temperature set in item . This temperature must be set to at least 6°C. If this temperature is not reached after eight hours of electrical heating, the disinfection program is terminated.
