Functions
Functions are factory-programmed routines that are used by your ChronTrol
timer. Functions cannot be switched manually.
Currently there are two functions available:
•
Function 1 . Daylight Saving Time
•
Function 2 . Sequence Start
Function 1: Daylight Saving Time
Function 1 moves the Time of Day clock forward by one hour at 2 a.m. on the
first Sunday in April, and moves it back one hour at 2 a.m. on the last Sunday
in October. Function 1 is automatically enabled when you set the date during
the setup procedure. If you need to disable Daylight Saving Time, see
Sample
Program 1 in Section 4.
Function 2: Sequence Start
After a power failure, Function 2 restores circuits to the ON position, in
order, at the rate you specify, until all circuits scheduled to be ON have been
restored. If Function 2 is not used, all circuits scheduled to be ON will
simultaneously switch ON when power is restored. See
Sample Program 2
in Section 4 for the factory-recommended Function 2 Program.
