We purchased a "new to us" house and my wife and I are fixing stuff all over the place.
I got real tired of remembering to turn that darn pool pump on and off all the time. Thus a Timer is needed.
A few days ago i purchased an ET100C from the depot.
Electronic Time Switch.
24 hr control.
3 yr battery life (assuming its alkaline - AA)
after reading their install instructions and viewing their diagram, something wasn't right. If i wired as per their instructions it'll go poof.
After some consultation with friends and searching web for some plain up front info. i found this site. It seemed to be the best place for info that was close. Although not finding an exact match to my predicament the info here was useful and helpful.
So i've decided to post my working timer install for those who may run into the same problem. Hopefully it will prove useful to others.
Hmm, don't seem to be able to insert pics.
i'll try to explain it clearly
Note power is OFF....Label box if you have to to warn others of what your doing.
1. Source power (14/2 power from a 20 amp breaker in a sub-panel)
2. Timer box with removable timer mechanism.
3. short jumper wire.
4. wire continues to the pump.
My wiring from 1. leaves the source and enters the timer box. The white wire attaches to terminal 1 labelled as LOAD. The HOT wire (black) from 1. (source) attaches to terminal 2.
Next i cut a small jumper wire from an un-used piece of wiring. I used black out of habit of keeping to colour coding. I attached the jumper wire to terminals 2 and 3 (labelled as line and line1 on the plastic cover).
Next was a attachment of the last available black wire that continues to the pump. This goes to terminal 4 (labelled as LOAD on the plastic cover).
Finally the only wire left is white and it was attached to terminal 1. (this ensures that the nuetral carries through completly.
After making sure all terminals are snug I replaced the plastic cover, turned on the breaker, check voltages across terminals. And don't forget to attach the ground wires to the ground screw provided in the box.
Pressed the button on the display to set the manual operation and pressed the other button to on and bingo my pool pump turned on.
The instructions in the installation paperwork for programing times are correct.
So that was easy, I tried to set mine for off-peak times as that is an expanding issue with hydro use these days.
Later i'll flip the switch to AUTO and forget it till closing time.
The afore-mentioned wiring diagram that came in the install papers makes the hook up look like you are jumping more than just #2 and #3 terminals.
It makes is look as tho you also have to jump #1 and #4. BAD DRAWING as far as i am concerned.
ok, tried attaching the pics (3)
box attached to interior wall
wired connections in working order.
