I want to use it to time a pool pump to run on high speed during the day and low speed at night , will I need external relays ? my pump is 110V 2spd.

If I were doing this, I would use an Intermatic ET1100 Series or ET1700 Series Electronic Timer. Depending on your motor wiring you may or may not require an additional relay.

As long as you can attach the tubes shown to a different pump, it should be fine. We have already upgraded our pump, so the pump can be changed out to a pump that does 220v, as long as the tubes running to the pool can attach to the pump. (I am not sure of the diameter, but fittings could be bought at a hardware store if needed.)

Not really sure; suggest checking with a licensed electrician. I am using this switch as a replacement to an identical one that controlled my 1hp pool pump, a use that this switch was primarily designed for.

This would not work because it is a 110 v and your sensor comes out with 24v. I think that you would be better off with this relay from Grainger http://www.grainger.com/product/OMRON-Enclosed-Power-Relay-2XC19?s_pp=false&picUrl=//static.grainger.com/rp/s/is/image/Grainger/2XC19_AS01?$smthumb$

Yes, it has NO (normally open) relay and alarm contacts. So connect your power source (110v AC, 12v DC, etc.) to one side of the output or alarm contacts and use the other side as the output. Connect the light bulb or other load from the output to ground. If the load is more than 3Amps you will need an external relay.

I would think so. I am using mine for a 1.5HP pump to power a water feature. One word of caution- this timer should be mounted high enough to allow your plug from the pump to be plugged into the bottom of the timer.

Yes you can use your external timer to control the pump. The pump will start in the prime mode speed and run for the time you designate at the SP2600. It will then move to speed setting V3 and run for as many hours as you program it for up to 12 hrs. It will then move to the V1 speed and run until power is cycled. Each speed, V1, V3, V2 can be set for any speed. When your external timer cycles the power off and then back on, the whole process resets and starts over. I run mine 2 minutes at 3000 RPM for prime, 10 hrs on V3 at 1520 RPM using 210 watts and have V1 set for 1520 RPM in case my freezestat needs the pump to run all night.

It depends on the wiring for the pump. If the wiring is correct, there shouldn't be any issues. ... I can set this timer for different times each day. And there is a manual override

I don't know I have a 120V and this would not work in my pool. They have a 12V also as you see here......you'd have to ask a pool person or an electrician. If it's an older pool it most likely requires a 120V It's also no small job to replace these pool lights. Very expensive check that out too. I returned mine. Be sure first which one you need as this company charges a $20 restocking fee.

I did. Just need to use a diode between 86 and 85 to keep the volts from killing fish. But I would use delay relay like (SRD-12VDC-SL-C NC Triggered Time Timer Delay Power Relay Module 12V DC). It keeps it from getting into that loop of the bottom of the container to the sump.

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.

Refer to a Sestos Model B2E manual. The manual is downloadable. If you operate this timer in the "Cycle Mode" you should be able to operate the 2 circuits alternately using the provided output relays. Depending on the load requirements you may need an external relay/s.

Go ahead... it is OK. the devide energizes a dry relay contact. you can use any kind of fixture with it up to the specified rating... a LED light is far beyond the max drain current.

You can hook it directly up to your wiring. No relay necessary. I use these for bow fishing and hook quite a few of them directly to the battery.

I do not believe this will work for your application. I don't think relays will respond correctly to only 6 volts

It does not need a separate circuit for the timer. I ran the 240 to the timer and (I think) 12 gauge from the timer to the water heater. I'm not qualified to answer the second question, but given the way you have to wire the timer I would guess that you can't wire safely w/o the neutral.

Yes it depends on the relay u use so get a nice solid state relay as well for it but input I'm not sure I run mine on 110v us
