Alarms
It will be specified in this section when an alarm must be assigned (i.e., when
an alarm must be set) for the Control Output 1 or 2 Assignment parameters,
or for the Auxiliary Output 1 or 3 Assignment parameters. For example, if
alarm 1 is set for the Control Output 1 Assignment parameter, then alarm 1
has been assigned.

➊ There is no control output 2 and no parameter assignment is displayed for that output.
➋ The Auxiliary Output 1 Assignment parameter becomes the program end output unless the Program
Pattern parameter is configured to OFF.
➌ For the 900-TC8, the Auxiliary Output 3 Assignment parameter is set as the control output for cooling.
(The Auxiliary Output 2 Assignment parameter is set for alarm 2).
