T10404R wiring help

[Jve]

I corrected the wiring that was installed prior to purchasing my home, moving the purple wires per the diagram so now my booster pump will not turn on without my main pump running However I am unsure what the white wires are doing or whether they are redundant with the purple providing power to the booster. should I leave it as-is?

JVE,

I initially only saw the first pic and thought "You did it wrong"..

Then I saw the second pic where you did it right... Edit.. Well, almost... See below.

The white wires run the clock and you want both clocks running at the same time. So, you are good to go.. No you are not!!

The white wires on the right side need to run off constant AC power like the white wires on the left side. Otherwise the clocks will be out of sync.

Thanks,

Jim R.

Don't thank me as I was initially wrong.. Go back and read my edited post..

In a T10404 the motor wires (white) are long enough to move from the clock on the right to terminals 1 and 3 on the left clock. That way the motor is constantly powered and the clock will keep time. If you just run power to the clock on the right it will no longer be "safety wired" and the booster could come on without the pump timer on.

You must have just edited it before I read it. Got the message that it is now wired correctly

The booster pump Line terminals are fed by the regular pump Load terminals, so the booster cannot get power when the main pump timer is off.

Yes, but that also removes power to the clock unless it is wired as I described. Its called "safety wiring" the booster pump. You must place the motor wires on timer one (filter timer) for the clock to run and operate the booster on a schedule and still not have it run when the filter is off.

 

[JamesW]

not have it run when the filter is off.

I agree that the clock wires need to go as you describe, but the booster pump cannot run when the main pump is off even if the booster pump timer is turned on.

Thanks all, I’ve made an update based on the comments which I think is the correct solution: moved white wire from booster slot 1 to filter slot 1, white wire from from booster slot 3 to filter slot 3.
Both clocks are always powered, booster only has power when filter is active.

Ignore out of sync clocks - i manually synced up after photo taken

That's a safety wired pair of clocks.
