Does this product feature a gradual start up? Or does it flip the pumps on at full speed all at once?

To answer your question. It does not. Sometimes it even starts it's own pumps in reverse (Lost my dear Yellow Tang like that). Check out Jebao (haven't looked back).

yes, It is working fine for me. tun the power off before connecting. suitable for small pumps for house circulating pumps. I hope this helped.

Putting on the first time took a few tries...it takes a bit more force than most others I've used and seems backwards to me for some reason. I think that I'm used to using my DC powered pump which has a lever that you push down (from vertical inline w/valve to 90 deg. perpendicular w/valve) - this one starts in the down pos. and is flipped upward to inline position to engage. However, once it's on it stays put during pumping w/no issues and the back pressure is enough that just flipping the lever is enough to pop it right off. It does take a fair bit of effort though to get it on there and fully engaged. Hope that helps.

It definitely does not have a gradual start, as some have indicated in the reviews. The lightest first contact in the trigger yields around 300 RPM's unloaded on my drill (I checked with my touch-tach). With the level of power this drill offers, even at this lowest trigger position the drill won't stall without a large amount of load. If you need delicate low-speed operation such as fastener driving, look for a smaller drill (perhaps a 3/8" VSR?). If you need a drill that will work continuously poking 3/8" to 13/16" holes in up to 3/8" thick steel as I did, this is your drill.

Yes the pump is one you twist one direction to open and the other way to close.

It looks the same. I have had 2 pumps so far and both have the positive and negative reversed. Be careful you might have to re adjust the positive and negative so it pumps correct.

Yes and No! When you first turn on the pump, it thinks for a while, then goes to its Prime speed. After a time it switches to V2, its second speed, and runs at that speed for a long time, before switching to V3. You can set the amount of time it runs at V2, as well as the speeds it runs at for the various speeds.If your power goes off, it starts back at Prime (3000 RPM) and repeats the cycle. Most people like a timer to shut the motor off at a chosen time, and restart it the next day, or whenever. So, I recommend you have a timer, but it is not essential.

Each pump has its own float switch! There is a top switch that sets off an alarm if both pumps fail to work. My AC pump starts about 9inches and stops about 4 inches. The DC pump starts around6 inches. It only starts if the AC PUMP DOES NOT

Yes, float switch has to reach the top to turn on. The system works best if lowered into a hole in the floot. I dug a hole big enough to lower a 5 gal bucket ( with holes drilled into it). Pump fits perfectly into it. Dont forget a check valve. Luck!

Nope. One speed and it has reverse also if needed if you get a clog. Just used mine last night actually for the last of the garden tomatoes. I froze them all to make my sauces in a few weeks

No, this is not an automatic pump. It requires manual and or float switching to opetate correctly.

We have the pump installed, and it works well. The pump only starts when we push the button connected to the unit, or when we push the button on the remote control. When the water temperature is reached, the unit stays off until the button is pushed again.

Not at first. It is only after the anti reversed pin gets kicked out. I do think that the constant startups from a wave maker cause this to happen sooner. If you do use these pumps, consider reinforcing the antireverse pin prior to use.

Yes it will start simply by plugging it into your standard AC house current. There are no batteries to charge. it is a standard ''plug in'' pump.

There is a speed switch on the Grundfos that I bought. I think it is 3 speeds, but I only use the full speed setting. If I were trying to rig up a thermostat to the pump, I suppose I would look online at Omega. It would be a pretty simple matter to rig up a relay to a therm switch to turn the pump on and off. Good luck

If the room is hot enough, the fan will switch to high speed and back to low when the room gets cooler if you have it in the Auto mode. As far as the pump, I would imagine it only has one speed and runs when the fan is running

I do not think so. I know when I turn it back on the pump needs to be restarted.
