it's continuous, the wheel has notches that operate the switch, 15 sec off, 1 sec on, 1 sec off then 15 sec on - repeat
I assume that the locking mechanism is controlled by the switch back to the control panel. when cleaning cycle is complete
and the temps are normal then the control board starts the motor and it unlocks the door.
so it look like its a 2 RPM motor
Could also use it as a timer for a prop and control a props motion.
