27 - Key Weather dependent target value regulation
This key activates or deactivates the function weather-dependent target value regulation. This function is only available in room
heating operation.
If the access authorisation in parameter [0-00] is set to Level 2 or 3, the key "Weather-dependent target value regulation" does
not work.
28- Key Parameter mode, test run
This key is used to set parameters and to start a test run after installation or maintenance work.
29- Key Programming
This multifunction key is used to program the switching times.
30 - Key Program clock
The main function of this multifunction key is to activate/deactivate the program clock. The key is also used to program the
control system. If the access authorisation in parameter [0-00] is set to Level 3, the key Program clock does not work.
31- Key Time setting and
These keys have several functions such as:
– Decreasing or increasing adjustment when setting the clock.
– Changing between display of the water outlet temperature on the Indoor module (RKHB), the ambient air temperature (outside
temperature) and the hot water temperature in the HybridCube.
– Decreasing or increasing adjustment for programming switching times in the program clock.
32 - Keys Temperature setting and
These keys have several functions such as:
– Setting the current temperature target value in normal operation or in switching time programming of the program clock.
– Setting the weather-dependent target value.
– Setting the week day while setting the clock.
33 - Keys Setting hot water temperature and
These keys are used to set the temperature target value for the water heating.
34 - Key Low-noise operation
In this operating mode the output of the system is reduced so that the operating noise of the Outdoor module (RRHQ) is reduced.
35 - Pressure gauge water pressure
The indicator on the pressure gauge must be in the specified range of 1 to 2 bar. If it falls below the specified pressure, the water
pressure must be increased by topping up the system.
1)
The function room cooling is available only for systems of type "HPSU..X".
