In this screen F2 is now functional. The F2 (NXT) key
changes the location of the cursor from one section of
the screen to the next editable item of the screen.
Pressing F4 (CHG) will allow editing of the selected
cursor location. When editing the time, use the F2 key
to move the cursor to the desired Hour and Minute
sections of the Start or Stop times. Ensure the proper
day is selected and the desired work week is shown on
the screen. Pressing F4 (CHG) while the cursor is
over the 7 of the Start of the screen will clear the
HOUR portion of the Start time and allow editing by
pressing the numeric keys of the keypad. When done
entering the new HOUR portion of the Start time, press
ENTER on the keypad. Editing the MINUTE portion of
the time is done in the same manner.
To change the ACTIVE work week, use the F2 (NXT)
while in a work week screen that shows >off< at the
top row. The cursor will move to that location. Press-
ing F4 (CHG) will change the the >off< to >ACTIVE<
as the example shows. This will now be the only
active work week of the timer. Returning to the main
menu and turning the Timer ON will run that ACTIVE
work week. The defaults are Start time of 0700 and
Stop time of 1700 for all days of all work weeks.
NOTE: To keep the timer from starting zones on a
particular day, set the start and stop times to the same
value, or 00:00. A typical example is that many plants
do not run production on Saturday and Sunday.

Pressing F1 will manually start the zones earlier than
the current start time. This allows starting all the
zones without shutting off the timer, which is useful if
an operator arrives at work early and needs to start all
the heat zones before the timer has started them
automatically. The zones will still shut off automatically
at the appropriate Stop time for the day.
If the current time is within the timer operating window
(after the Start time but before the Stop time), the
following screen is shown.

Pressing F5 will shut off all the heat zones before the
timer does it automatically. This saves energy when
producton ends early by allowing the heat zones to be
stopped for the day.
When the timer is turned OFF, the Therm-O-Flow Plus
unloader will operate normally, leaving the zones in
their current state. (If the zones are in the ST OP
mode or the RUN mode, they remain there).
