5.5 Setting up a vacation program
To save energy, we
recommend that you use the
vacation program during a
prolonged period of
absence.
The vacation program is
activated automatically at
the previously set vacation
start date. While the the vacation program is running, the text
line displays Holiday. The current room temperature appears
in the value display.
The factory settings guarantee energy-saving and safe
operation during your vacation. The room temperature used for
heating between the vacation start and vacation end dates
corresponds to the setback temperature in the automatic mode
(see Changing the setting Chapter 4.2, page 9).
If the CRC200 is used as the controller, water heating or
temperature maintenance is off while the vacation program is
active.
After the end of the vacation program, the user interface
operates again with the set time program (heating and setback
phases).
