Setting the time program for heating/cooling
7. Set the start and end points for the
relevant time phase. The length of the
white bar inside the time diagram is
matched accordingly (see the follow-
ing example).
8. Select the required operating status.
The individual operating status is dis-
played by bars of different heights
inside the time diagram (see the fol-
lowing example).
Note
Where several time phases overlap,
the operating status with the highest
bar takes priority.
Example:
■ Time program for Monday to Sunday
("Mo-Su")
■ Time phase !:
0:00 to 8:30 h: "Reduc."
■ Time phase ?:
8:30 to 12:10 h: "Normal"
■ Time phase §:
13:00 to 18:30 h: "Reduc."
■ Time phase $:
20:00 to 22:00 h: "Fixed value"
■ Time phase %:
22:00 to 24:00 h: "Reduc."
