This JSL-72 timer is specifically designed for controlling coffee grinder.

It can count from 0.01" to 99.99" or from 1" to 99'59". Counting direction

can be set by user(counting up or counting down). Accumulated time/

Operating function modes include single dose, double dose and

manual. Most function features can be activated by front key pad or

remote switch. However, manual function can only be accessed

mode. Timer adjust function can be deactivated to prevent any
