By pressing "set" and choosing a temperature you can only set the heating relay temperature (which position is visible by the red dot in the display) but press and hold both the arrow up and arrow down buttons together for about 10 seconds and the first led (of 4) on the left will light up. You can now set the temperature difference on which the pump will start (relay 2) with the up and down arrows. Use set to go to the next setting: Led's 1 and 2 will light up and you can change the value and so on. On the website you can see the other settings you can change, indicated bij one or more led's on the left. I must say I'm not sure what the difference is between "heating temperature diference" and "temperature diference".
I snapped open the plastic case and de-soldered the transformer. Then connected a 12v wall-transformer to the place on the circuit board where the Secondary of the transformer came out. Also, here are instructions on operation www.eliweli.com/en/products/p02/158.html
I think they do have a 120 AC model I use mine to run a small 12 volt pump so I have a power supply that runs on 120 240 or are Universal as they call them they got my 12 volts. The input is the problem and I would have been happier with a 120 model. Mine still working
You can modify this to run on 12v AC or DC. There is an LM317 voltage regulator with a bridge rectifier behind the transformer. the output of the transformer is 10v AC. Just remove the transformer and install jumpers. Any voltage between 10 and 30v should work. Use a 12v wall wort. You could try and find a 110v AC transformer to install instead but why bother. The manufacturer does make 110v AC and a 12v model of this as well but they are hard to find. You would probably have to order from China. There are English instructions available.
Thank you Steven Clunn! This helped me a lot, since the manual is written in a very confusing way. Greetings from austria.
Thanks, Steve and Mrs.
Great video. Thank you for ur help

Thanks for your information, the price on this was good and it's still working.
Can you show the connections, please?

I am still hesitating buying that controller, due to lack of manual / info. Good video anyway
The English manual is on the manufacturer's website: www.eliweli.com/en/service/download/
Deborah and Bruce young posted something that my help in the comment section
Je voudras en francais
Can you show how you do the connection?
So u mean how it powers the pump? I used a 12 volt pump and the meter relay makes a connection
@@steveclunn8165 yes yes exactly... Can you show the tutorial or make one on how to make these connection?
will it run on 110v?
