I have a 2 hp pump that can be wired as 120v or 240v. I have it set as 120v. Can I use this relay to activate the pump?

Yes, you can use it. The relay is activated by the 24V line so the contacts itself you can use any voltage you want.

Make sure that the clock voltage is correct for your application. The 120U is 120Volts on the clock , but still uses 240Volts to operate the pump.

I'm using it with what I believe is referred to as a two wire pump. It is 240V, switches just the two 240v leads (black and white), has ground screws and has no provision for a third wire. One thing about the low pressure cut out switch on this. It may have already saved my pump. We have some kind of problem developing where the pump is not able to keep up with the flow. The switch tripped a few times then stopped when the condion seemed to have righted itself. The only negative there, not much of one, is that the swich to restart the pump is a little tricky if it trips. You have to find the sweet spot where it engages. In my setup I can here it start to flow so it's not a problem for me. I'm using it with what I believe is referred to as a two wire pump.

Gary, I bought this pump last spring and am very pleased with it's performance. I'm running four zones, each having 1/2 dozen sprinkler heads and this pump is more than adequate. I believe most 220v motors can be wired for 110v also. It has been awhile since I have converted one and suggest you Google for instructions. It is 18 degrees and dark outside, otherwise I'd measure my inlet/outlet pipe ODs. I believe they are 2 1/4", same as the pump I replaced. You can always use an adapter, if your manifold is different. Gene, Michigan.

Imprinted on top of unit is 12 volt, 3 Amp with 6 amp fuse. Three wires, one negative plus two positive. One positive to run using the included/enclosed automatic float and one positive to run the pump manual from a switch. Your choice, either or both.

Yes, it's what you want to use. I have my well pump that's 220 volts plus other electrical on my generator using it.

The thermostat is designed for a line load based system such as a baseboard heater, motor, hot water heater, etc. You can use it for either 120v or 240v. I assume that your 120v relay will work just fine, it certainly should draw well under the 16 amp capacity of this thermostat.

The voltage rating is 110v. I don't believe the pump can handle 240v. 240v may burn the pump up so I would not recommend that.

yes but make sure your controller output voltage is enough to pull the coil in for the pump starter. (example coil voltage is 24 volts your controller has to be able to output that voltage. Hopefully this information is helpful.

It should be pretty simple. Just follow the wiring diagram. If you do not have a timer on it now I assume your pump/motor is wiring from a junction box. You will disconnect the feed wires from the wires to the pump/motor. The Feed wires will connect to the L1 & L2 terminals and the wires going to the pump/motor will connect where it shows on the diagram. That is the basic wiring for the typical set up.

Depends on amperage--I think so. Suggest you ask GOGGLE, as I am no expert. I just know it handles my 2hp pool pump just fine and the pump pulls high amps at start up. hope this helps. RK

A 2 hp motor @120v draws 20 amps. The rating on relay contacts is only 15amps. So no.

The pump your looking to replace is a 1 speed pump for a spa, this is two speed pump for a pool, your existing pump is probably hard wired and this pump is for an 120v electrical outlet.Hope this helps

I'm not sure, but I would guess that they want a minimum of 100 volts while the pump is running. I just replaced my existing pump (which was larger) and plugged it into the existing receptacle. If the size of the pump is the same or smaller there certainly shouldn't be a problem. If you want to do the exercise, connect a voltmeter to a nearby plug on that circuit and observe the voltage while someone turns the pump on and off.

Unfortunately, your idea doesn't work as described on a 2-wire 220 circuit. That is, unless you use the bare ground as a neutral, and that isn't really too Kosher, although logically I don't know why. It would be nice to see what my submersible well pump, window mount A/C unit and air compressor are using.

This pump runs on 110-120 volts. If your adapter does not convert the voltage from 240 to 120 then it will not work. You may need a step down tranformer to convert the voltage.

It's a switch. Should have no problem activating a relay. Use the relay for any load compatible with the relay contacts.
