Does it require continuous 12 volts? I am thinking about using it to control a small water pump that circulates water in a solar heater.

Not sure how to answer. I have mine in the circuit so I don't know if it is drawing any power or not. If it does then it's tiny. Been this way for ~6 months now with now issue.

It requires a constant 12v but only draws current to run the timer, which is minimal. I don't guess I understand the question. I don't know how it could be hooked up without a constant power supply. The timer is hooked in-line between te battery and the item needing to be turned on and off. I use it to control a solar heater. It comes on and turns off at a predetermined time.

This unit Has a Booster Pump and Does Use A Transformer To Run. I Believe It Was 12 VDC That Actually Runs It , That Being Said You May Wire It To Run On A 12 Volt deep Cycle Battery and Recharge It Whenever Needed As Well. The Unit W Pump Is Really Used Where Water Pressure is To Low For The R/O Membrane To Be Efficient IfYour Pressure Is Good You Don't Really Need This Unit.

I agree with James, I don't think it would work. The unit is designed to connect a 12V source to a load of some kind. I use mine to turn on/off a fountain pump and a second unit to turn on/off the fountain lights. You might be able to use this unit to open or close a solenoid which in turn could connect/disconnect your "wires" but that would be more complicated to set up.

not really sure,i use mine to charge 12 volt battery to pump water from rainbarrel system,works good!

I believe the "output" power from the controller is only 24 volt AC. So it probably would not directly provide control for a 120 volt pump. However, you can go directly to the RAIN BIRD site and find the manual and spec's of this unit which will give you more specific answers.

This switch is rated to switch 2400 watts of power at 120 Volts. If your water heater has an element that is less than 2400 watts, and runs on a 120 volt circuit, yes you can use this. It is not likely that your water heater meets these requirements. You can, however, use this switch to switch a relay that is rated to turn your water heater on and off. An inexpensive example of this is the Packard C230B. It will switch 220 volts up to 6600 watts and has a 120 volt coil. This is a mechanical contactor. You can also look for a solid state relay that will be quieter and last longer, but cost more. This switch is rated to switch 2400 watts of power at 120 Volts.

Yes, these little pumps are quite small. I have been using them for 12 volt swamp-coolers (in a motor home), and used one for a fountain pump outside. Haven't had one fail yet. Good product.

I would say that this unit can control anything that is low voltage controlled (ie. solenoid). I don't think it would work as a switch on a 120v pump for example.

The water pump that comes with this unit runs on 12 volt current. Most typical gas powered generators put out 110 volts.

This is not a pump or a 12 volt powered system. It is a buffer so that the pump doesn't short cycle quickly. It evens out the pump so it stays on for a while and then shuts off until the pressure drops to a level you set by pumping air into it to your chosen pressure. It comes factory pre-set with compressed air. I would like the 1 gallon one but don't have room for it. This tiny one at least makes the pump run for a while and then briefly stop until it comes on again.

I returned mine - too small and heat was not adequate. Very narrow. I don't recall if it was 12 and 120 volt. I used it on 120 volt (house plug). It was not for 220 volts.

Mine is hooked up directly without a controller to a water pump. It will depend on what you are using it with--the voltage varies depending on the sun.

You know that this is a 120VAC heater? I think they make 12VDC versions but unless you have an inverter mounted somewhere, this is not going to work.

While I have not tested it, I'd guess no. 12V parts and 120V parts are very different. If the pump has a power supply that plugs into the wall you can use the switch to turn the power supply on and off.

Assuming there is a constant 12 volt direct source, the pump is going to draw 3 to 5 amps. amps x volts = watts. At 5 amps that would be 60 watts. With a battery in line it would work. Straight off a 50 watt solar panel probably not so well.

I just installed one of these pumps and I used one, 100 watt panel wired directly to the pump. It operates just fine, only runs when the sun is just right on the panel but where I am in Calif. it operates for about 4 hours this time of year and probably will run longer in the summer. It also pumps about 1.6 gal. per min. which is very adequate for my use. The 4 amp at 24 volts is the max amount of amps that the pump will handle.. I think my panel put out a max of 2.6 amps. Hope this helps. I opted not to use batteries, just more upkeep and expense.
