is active. The thermostat automatically changes between Comfort and Economy
mode according to the time scheduler using the bus.

When you are in the Auto Timer mode, and you change the operating mode, the

temperature is maintained according to the time schedule.

(factory setting) or Comfort (selectable via P88).

by users, window contact or presence detector. The screen displays OFF.
