Posted 27 Aug 2018 Hello, I'm Jaime from Spain and I have a watering installation with a m810 with a LCD display and it doesn't work. It has been working for the last two years without any problem until yesterday. The PWR light is on but the LCD display doesnt turn on. It's curious because the other device, the pressure variator shouldnt work if the 810 doesnt work. So I dont know what to do. I would be very pleased if you can help me.

Posted 27 Aug 2018 I think the LCD is a removable add-on unit. In that case, it's entirely possible the 810 is just fine and the LCD itself is bad. Have you tried unplugging the LCD and plugging it back in? Share this post Link to post Share on other sites

Posted 29 Aug 2018 Hi, I tried it and it still doesn't work. The pwr light is on but the rest is off. Does this LCD usually fail or not? If it is true, changing it I would solve the problem? I have only switched off and on again. Thanks for your answers Share this post Link to post Share on other sites
Posted 29 Aug 2018 We've never actually used one of these. We bought one to test it out but never put it into service. Does stuff controlled by the ML810 operate? If so, it's just the LCD unit. Contact your local AB distributor for pricing and availability. They're not that expensive, so I would buy 2 so you have a backup. Share this post Link to post Share on other sites
