Time Setting
| Knob 1: delay gear setting, “s” for second, “m” for minute, “h” for hour,
“d” for day, “ON” for relay action (15-18/25-28 closed), “OFF” for relay open
(15-18/25-28 open).
---|---
| Knob 2: fine adjustment of delay time, 10% ~ 100% adjustable.
Delay time = knob 1 × knob 2.
Example 1: it needs to be set for 5 seconds. You can set knob 1 to 10s, knob 2
to 50%, and delay time = 10s × 50% = 5s.
Example 2: it needs to be set for 8 minutes. You can set knob 1 to 10m, knob 2
to 80%, and delay time = 10m × 80% = 8m.
