Question 1

How are the differing duration settings set?

Accepted Answer

the manual is posted online - here's the configuration procedure.

1. Short WHITE and GREEN wires to the ground (or push the buttons connected to WHITE and GREEN
wires), and then supply power to the timer. Once the pump turns On disconnect WHITE and GREEN
wires or release the buttons. The timer is now in the configuration mode.
2. Briefly connect WHITE wire to the ground. Power will be supplied to the pump for a short duration.
Each time WHITE wire is connected to the ground adds +10 seconds to the ON period. Connecting
GREEN wire to the ground adds +10 seconds to the OFF period.
3. Turn the power Off to the timer if you do not need to change the duty cycle. Or continue to the next step.
4. Short WHITE and GREEN wires to the ground at the same time and disconnect. The pump will turn On
for about 3sec, then shut off for a 1second and turn On again. Pump runs at 100% duty now.
5. Each time WHITE wire is connected to the ground decreases the duty cycle and reduces pump speed.
Once you get to the speed you want pump to run disconnect the power from the timer

Is this the wifi version that i see on youtube? That i can program from my phone?

Accepted Answer

No, this is not a wifi version. Wifi version is slightly bigger and has “WIFI” in the label

Question 4

The unit is installed in a dual switch (fill -recirculate) but it is feeding back power to the other switches. how i correct that?

Accepted Answer

I would check the wiring.  You may have your positive and pump wires mixed.  
Make sure the battery + is connected to the center of the switch, the pump + is connected to one side, and the timer red wire  is connected to the  other.  
I wired mine the same way, using a DPDT switch, with center off.  A SPDT would also work.  I use the other pole for an indicator light, to show the aerator is on.
