Turns on with a wired in button or wireless remote, but how does it turn off? Temp setting is on water heater.l

The pump has a thermostat in it and when it senses a 6 to 10 degree rise in water temp it shuts itself off, so it never runs continuously. Now I am referring to use with an on demand water heater. It should work the same pulling warmer water from a tank type water heater, senses warmer water in the line and shuts itself off. Hope this helps. Bill

It has a built in temperature sensor that turns it off when the hot water reaches it.

You're exactly right about the sensor being at the water heater in the return line. Pushing the button causes the pump to turn on. It stays on until it senses hot water has made it back to the hot water heater. That's a bit of a waste as it fills the return line unnecessarily, but I suspect it was done to avoid having to run two wires--one for the button and one for a remote sensor at the distant fixture. I think this is still a good set up--the alternatives have timed pumping--a much larger waste.

The pump has a thermal sensor in it. It connect sbetween the hot and cold water lines and when you press the button, it pumps water from the hot line back into the cold line until it senses the water temp is right, about 75 degrees F, but I'm not sure. There will still be some cold water in the shower/tub/sink hot water line when you turn them on, but the delay for hot water is substantially reduced AND you don't waste so much fresh water going down the drain. We live in CA and water here is expensive and getting more so. We use this device every day and we love it. I've recommended it to several of my friends. The pump has a thermal sensor in it.

It turns off automatically at a preset temp when the thermostat senses the water is hot. I am sorry I do not remember what the temp is preset at, nor if there is a place under the cover on the motor that can set it. I just installed it and it runs very well, and is almost silent, which is more than I can say for the first pump I tried from another manufacturer, which sounded like a table saw until it failed.

When you use button it will start circulation water, until teperature rich point, that set at the factory inside of the pump.After that it will automatically shuts off (1-3 minutes)

From what I remember from Skinny and Steam, E=IR ! That should explain it. Other than that it turns off after about 30 seconds and the water is hot. Obviously I didn't do well in those classes.

The pump has a thermocouple ...temperature sensor ...which turns the pump off when the temperature reaches somewhere in th 95 degree range at the return side of the pump. Way cool. I am a builder and we have been installing these for years. Still pricey but they work great. No wasted water whatsoever. Allen

The top button is your answer, sounds like it might be faulty. I'm sure you've already tried to just take it out and unplug it and let it sit an hour or so then 1) put it back in the water for 20-30 minutes, 2) plug it in and set the temp. I love mine - and 78 works for my Beta but it will cycle through the choices just fine. I like the way it blinks at a different temp to show actual water temperature.

It's automatic. As soon as you unplug it the unit stays hot for one hour. There is no on off switch

There is a button on the iron that allows you to shut it off without unpluging. It's the same button that turns it on.

Sounds like you have a bad control board. The temp can be set on both the front face of the unit and with the remote control. Take it back and get a new one!!

It's in the remote, you can set the remote to a certain temp, when that low temp is reached in the room at the remote the fan will turn off automatically, when the temp goes back above the set temp the fan will go on again by itself, of course you can override this feature and have the fan just stay on no matter what the temp is.

On the lower right hand back corner there is an on/off switch that I use when I'm not needing hot water. You can also scroll through on the menu at " set time" and the "off" option will come up.

One button on the switch turns on the remote, the other shuts the remote off....so basically one turns it on, the other turns if off. Its a very reliable unit by way. Have had no issues with it. Built very well

It won't shut power off if "water gets low", but it won't turn on heater if water is in designed temperature range. so it won't be over heated.

There is a remote control on a cord with up and down buttons for the time and the temperature, as well as on and off. Hope this helps.

There is no on/off switch or temperature control. Plug it in and it's on; unplug it and it's off. It runs continuously. I do not have it in front of me, but it is about 18"+/- long and about 3-4" in diameter. The heating element is protected within a ventilated stainless steel sleeve as can be seen in the photo which protects it from touching any surface. I'm sure a plastic bucket would work OK. Wiring is completely waterproof. I submerge the whole unit when using it with no ill effects.

It has a last used temp feature. It's actually very simple. The valve handle rotates front to back to go from cold to hot. It pulls to the right to turn it on and control flow volume. If you don't move the lever in the front to back plane when you turn it off the next time you turn it on it will be at the same setting. Of course if you don't turn it back on for an extended period of time the water will not be at the desired last temperature until the hot water reaches the faucet from the water heater .

My temp lcd turns on and shows temp while water is on only. Had mine for 2 yrs now and havent had a problem. The button below my lcd never did anything - not sure if it was ever suppose to have a function.

When the light is off, the water heater is off according to the on/off schedule in place. Turn the water heater on by pressing the button or change the on/off schedule for the time you want it to be on.

There is no on/off button. It connects to the tub/shower faucet and once temperature of water is set, I pull the lever to get the water going through the shower head. Hope this helps.

The button is an on/off switch. If you turn it off, no steam. Nice, if you had to stop in the middle of the job to tend to something else.

There is no option to turn it on and off via remote. I just unplug it from the back when not in use
