• Absolute Time Mode
The timer expires at the times determined by the reference time and the interval.
The reference time can be set to the hour (00 to 23).
Example: Reference time: 00:00
Interval:
10 min
The timer expires at 00:00, 00:10, 00:20, ... 23:40, and 23:50. For
example, if the timer is set at 09:36, the timer expires at 09:40, 09:50,
10:00, and so on.
• Relative Time Mode
Timing begins when the timer is set, and the timer expires and then begins timing
again at each interval. With this mode, the timer will stop when there is a power
failure and will not resume afterwards.
Example: Interval: 00:15
The timer expires every 15 minutes.
