Setting the Time and Date
— The ComfortLink control has a
time and date function. This can be useful for diagnostics to de-
termine when alarms occur. The control is factory configured
for the proper date and for use in the Eastern Time Zone. The
control must be checked and corrected if necessary. The correct
time is important if the machine is to function on an internal
time schedule and display a proper time and date stamp for
alarms. The time and date will be displayed on the default ro-
tating display of the Navigator module. The time and date can
also be checked and changed under the Time Clock mode as
described below.
To change the time, press the arrow key to move to the cor-
rect hour and press . The minutes can be changed in a
similar manner.
To check or change the date, the following items must be
checked and changed if necessary.
NOTE: WW is the current month of the controller, (01=January,
02=February, etc.).
XX is the current day of the month
YY is the day of the week, (01=Monday, 02-Tuesday, etc.)
ZZ is the year of the century, (06=2006, 07=2007)
Changing the Unit of Measure — The Navigator display has
two options for unit of measure on the display, English or SI
