peration And Installation Manual

Section 8                                                                                 Entry Code Details

ENTRY CODE 81:   SETBACK OVERRIDE

PRESS            +           = ENTRY CODE

ENTER CHOICE                                    = MINUTES OF SETBACK

RANGE IS FROM 1 TO 240 MINUTES

PRESS           = SAVE KEY

This provides flexibility to the setback schedule. For example, a school might set back every
night of the week, but occasionally have a special activity in the evenings. To warm the
building, you could re-enter the code for that night and change the settings. However, it is
much easier to enter Code 81, the number of minutes of override, and then press #.
