Operation
NOTE
After each defined heating period you have the option to complete programming
prematurely after entry of the respective SETBACK TEMPERATURE (and to set only
one or two heating periods per day). To do so, turn the menu-button slightly to the right.
The message READY which is confirmed by pressing the menu-button will
appear on the "R-Tronic" display. After that, the message SAVED will be displayed.
Programming of the individual profile is cancelled with the back-key. All previous
entries will be deleted now.
