Intermatic Timer on a Pentair Variable Speed pump

New house with a pool so I'm learning and fixing variuous things. I ntoiced there is an intermatic timer connected to a Pentair Variable Speed Pump. The pump has a control panel that says "running on schedule". It looks like its running on a set schedule programmed with the control panel.

I'm wondering why there is a intermatic timer connected to it. I opened the box and I see there is no "off" position, and the intermatic timer is actually set to always on. I assume I can disconnect this thing and connect the pump directly to the breaker?

See image below.

That looks like an Intermatic T-103. Can't tell for sure without knowing the timer voltage.
It should be power in the left side and out the ride side.
It looks like the white/neutral was run in there for a 120v timer motor.

The white would get capped off.
The two incoming black wires would be connected to the two outgoing black wires.
The green stays connected or needs to be connected to ground.

Gotcha.. Why would they install that thing and have it turn to "On" all the time?

It probably worked well when it was installed. From age and weather it probably failed.

But I mean, the pump has its only scheduler in the controller. So a timer is not necessary right?

Maybe the timer was there first and then it was replaced by that other controller.
Two timers are not required.
