Note: 1. The display functions (display clear: -CD@ and day/month display: DAT1) cannot be used and will be ignored.
2. Only the memory area ranges supported by the pre-V1 CPU Units can be used for Timers, Holding Timers, Counters, Weekly Timers, Calendar Timers, and
Displays (i.e., only half of each).
3. Only 6 inputs and 4 outputs can be used in the CPU Unit I/O bits. Any others will be ignored.
4. Twin timer operation for timers, multiple-day operation and pulse operation for weekly timers, the 8-digit counter, and 8-digit comparators cannot be used.
New Zealand and Australia cannot be set for Daylight Saving Time (DST).
