Double check your slide switch.
For timer: set switch to TIMER
For thermostat: set switch to ON
If slide switch does not operate, then Autocirc may be defective

1) Household AC wiring will not affect the timer.
You can check your outlet using cheap circuit analyzer from home center.
The clock rotates one direction and the pins push small lever down which turns motor on-off.
When the OFF pins pass, the small lever snaps back and the motor turns ON.
I cannot immediately find operation manual for the E-1 model.
Typical ACT303 auto circ manual says following:
2) If timer controlled operation is desired, set timer and move slide switch to TIMER:
Manual says: tabs/pins are outward for ON times.
Another sentence says UPWARD, so I don't know which way the pins are set for sure.
So if you want timer ON for 2 hours, you would set 4 consecutive pins outward or upward.
ON for 6 hours, set 12 consecutive pins outward or upward.
If the timer turns ON in reverse of instructions, then set the pins that way.
Autocirc does not make the timer, they buy timer modules from clock-makers like Grasslin, Intermatic, etc.
3) To operate Autocir thermostatically without the timer, slide switch to ON position.
The clock dial will continue rotating
