Help with new Timer and twi speed pump

[jluzbet]

Help a Dummy out, almost at finish line.

Hi all,
I have a two speed pool pump and I just changed my timer to a wifi one, I got everything up and running but I am missing where to connect so I can have pump at low speed, running full speed only right now, any Idea? Will be Yellow to pump.

Thanks

J,

We need more info... What voltage is coming in on the L and N connections?? 120 or 240?

What are the two relays controlling?

In general, a 2-speed pump needs a SPDT relay to change between Low speed and High Speed... When using 240 volts, L2 would go directly to the motor's common connection. L1 would go the timer relay com connection and then NC output would be connected to the Pump Low and NO output to the Pump High..

You need to follow the diagram on your motor!!!!

Thanks,

Jim R.

You need a two-speed timer. One that will guarantee that both the high-speed and low-speed portions of the motor are not powered at the same time.

Its 120 each for 220 v, so both doing 120 each, pump has 3 cables now only one missing is the one that does low speed.
Could it be this is not a ideal timer for it

J,

That timer will work, because it has both a NO and a NC set of contacts..

Please tell me what is wired to the #1 set of contacts and then what is wired to the #2 set of contacts.. Is your timer currently wired to control two different things???

If you connect the wires wrong, your pump will be trashed in about half a second.. You can NEVER have the High speed and Low speed input hot at the same time..

We need to know the following..

Which wire is connected to the Common connection inside the pump
Which wire is connected to the Low speed connection inside the pump
Which wire is connected to the High speed connection inside the pump.

Thanks,

Jim R.

It can if the common is hardwired, high is to one side NO and low to the other NO and they are never allowed to be closed simultaneously.
That is far more likely than a SWG cell "exploding" if a flow switch fails.
Safer to say, "No, it can't" than "Yes, but under these safe conditions only," especially if one is not familiar enough with electricity to do the job safely.
Since that is a "dumb" Wi-Fi switch, there is no logic to prevent it in the device itself like in an Intermatic P1353ME, which is not Wi-Fi, unfortunately.

poolman..

The OP's timer has two relays... The 2-speed pump would only use one relay.. I agree that you can't try to use one relay to control the High speed and the other relay to control the Low speed.. That would lead to disaster..

But, if the high and low pump connections are wired to the NO and NC contacts (on the same relay). it would be impossible for the relay to be in both the NO and NC positions at the same time.

Kind of why I asked the OP what else the timer was controlling besides the 2-speed pump, but I have yet to see the answer.

If the OP is trying to use both relays to control the 2-speed pump, then that is totally the wrong way to do it.

Thanks,

You will not be able to turn the pump OFF wiring it that way.

The pump will run either low speed or high speed.

That would also be against the NEC which requires an emergency disconnect within reach of the pump if the pump CB is not within reach. And CBs should not be used for on/off switches unless rated for that use.

Thanks for your time
Common Black to One of the lines
White to the other
Yellow says low speed but not connected to anything, I don’t see how I can activate low speed on this timer seems like all is 220.
Pump is working fine just at full speed

Got it now makes sense… guess this timer no good then, ill just get one with individual circuits

Allen,

Good point.. I was thinking this device was just being used to switch between the high speed and low speed, like the switch that is often on 2-speed pumps..

Thanks,

I got me the pe153 is this a good one?

True, but the pump would run 24/7 at whatever speed the NC relay was wired to. Would need the breaker, or auxiliary manual switch, to turn the pump off. Only the NO side would be timed.

Yes, that is the P1353ME in a box. Be sure to set it up in "Mode 7." Instructions are in the manual which you need to read. The clock comes set for 240V, so you shouldn't need to make any changes. You will need to program the time and the schedule for high and low speeds.

Your "common" wire will go to "Circuit 3" on the far right of the wiring panel. The "high speed" to "Circuit 1" and the "low speed" to "Circuit 2." Wiring that way means that all power to the motor will be "off" when the timer shuts it down and the two speeds cannot come on at the same time.

You add a jumper wire from terminal 1 all the way to terminal 7 to power the "common," then a jumper wire from terminal 2 goes to 3 and 5 to power the speeds as the time clock changes. The motor will always start on high for a few minutes in order to prime the pump, even if you push the circuit 2 button first.

To run the pump manually you have to push the Circuit 3 button as well as whichever speed you want. If you turn the pump on manually, it will stay on until the next programmed event and then revert to automatic again. If you want the pump to shut down after a certain amount of time, again the instructions are in the manual.

Ty, as soon as I get I’ll handle… appreciate it
