Notes on Programming:
a) All programs must be in consecutive order, i.e. program 1 must be before
program 2 & program 2 before program 3. If the wrong order is programmed
error messages will be displayed
b) If only 2 or less programs are required, for the remaining programs enter
the same on & off times, e.g. Prog 3 on 8:00pm, off 8:00pm. This ensures
the unwanted program is cancelled.
c) Programming past midnight is NOT allowed. An error message will be
displayed. To overcome this the program needs to be split as per example-
Desired program period - on 10:00pm off 7:00am
make Prog 1 - on 12:00am off 7:00am
make Prog 2 - on 7:00am off 7:00am
make Prog 3 - on 10:00pm off 12:00am
Progs make up desired program period leaving prog 2 available for a program
during the day.
d) if you try to input the off time before the on time an error message will be
displayed. Press SET to continue.
