Welcome too. It was the same for me. That week it started to get stuck like this, I got scared because I'm home alone with my baby, my husband is away. I couldn't turn this regulator off or on, no button worked. I turned off all the traffic jams in the house twice and he calmed down. It started to work normally. I called an electrician to make me a central heating pump and underfloor heating for a cable, so that in case the controllers still go crazy, I could turn this pump on manually. He supposedly did, but insulated the plug because there was supposed to be electricity with the pump running. Today the regulator crashed again. The water in the fireplace boiled. It gurgled all the time. I isolated and attached this plug from the pump to start it and release water to the installation. Unfortunately, after it was manually turned on, the plugs blew out and the regulator burned down. The water in the fire boiled for another hour and there was nothing I could do. And my question is: you need to buy a new regulator or throw it out and call some good electrician to make this pump, or actually two pumps (one for floor heating and the other for hot water) so that they can be turned on mechanically, i.e. I light the fireplace and mechanically turn on both pumps. They are walking around and, for example, at 9 pm the wood will burn out and I turn off the pump. Can it be done this way? Does it have to be this regulator which, as I can see, breaks down frequently ...
