osmolator ATO no speed adjustment?

[atraperegrinus]

i have a 3155 osmolator ATO with the 5017 controller, but when i open the case up, there is no potentiometer to adjust the pump speed.

do i just have an older model without this feature or what?

This feature was added in Nov 2011, before that they were always at full power.
