Wrong setting
The position indicated by the arrow in the figure is the wrong setting position,
and the delay position can only be set in four positions of 1s, 10s, 100s and 10m.
When setting error happen, the red LED will flash, and it needs to be reset after
the power off 30 seconds.

Caution
The products must be installed by qualified electricians. All and
any electrical connections of the product shall comply with
the appropriate safety standards.
Setting instructions
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.

Knob 2: fine adjustment of delay time, 10% ~ 100% adjustable.
Knob 1: delay gear setting, “s” for second, “m” for minute.
Note: To ensure the delay and normal operation after power off, the power-on time of the product is at least 3 seconds.
