Chaining Notes
•
Each program sets operating parameters for a 24-hour period
ending at 23:59 (midnight).
•
If a program is run without being chained to another
program, it will stop running at midnight.
•
For continuous operation, programs must be chained together in
series, with the last program chained back to the first to create a
loop.
•
If there is only one program, it must be chained to itself to
allow continuous operation.
•
If a program is not in the correct format, when you attempt to
chain the program and error message will appear. Programs
may be incompatible if they were written in different versions of
software.
If the controller is not able to follow the chain:
•
an alarm(s) will be displayed and an error message will indicate
why the chain could not be followed
•
the current program will run continuously
