Setting the Programe
There are three (3) program options :

# 3 = User Defined
It is possible to set each day to operate on any of the above programs, this is explained
later in the guide.

TU-8A will ask if you want to ERASE PROGRAM FIRST? this will wipe the current program
memory leaving it clear for a new schedule. Press <+> :YES or <->:NO
The display will display

XX:00:00 00000000
Using the + and – buttons set the desired time, displayed as Hours, Min and Sec pressing
ENTER to jump to the next setting. The eight (8) 00000000 represents the relay outputs
which can be triggered 0=Not Selected 1=Selected. Using the + or – button will change
the relay status. Any combination of the outputs may be selected.
Once the required time and relay combination are programmed press SET/SAVE and the
message CHANGES SAVED will display for a short time before the TU-8A will jump to
the next EVENT.
After saving your program information ABORT will return you to the Home Screen.
Please Note:The TU-8A can provide 64 events per day, this represents 32 on and 32 off.
The duration of the relay activation is determined by the time difference between EVENT
#01 (starting the relay) and EVENT #02 (closing the relay).
For Example:
EVENT #1
08.30.00 10001000
EVENT #2
08.30.30 00000000
At 08.30.00 timer will activate/trigger relays 1 and 5, at 08.30.30 the program will de-
activate the relays, 30 seconds after the first command.
The minimum time period between events is 00.00.01 (1 second).
PROGRAM #2 and PROGRAM #3 are configured in the same way above.
