The boiler does not work at full capacity due to improper connection

Good day to all! Yesterday I completed the heating for my beloved grandmother - a one-pipe Leningrad unit with a bottom connection through a valve (instead of a stove, my health doesn’t allow her to be heated) I call in the morning, and she says that the radiators are not hot, but only hot, i.e. you can hold your hand on them as you like. Almost all of the air has been vented (although it took a lot of time), the system works completely, the pump pumps (stands on the back) and the only thought that remains is the wrong connection to the 220 network. Why did I come to this? The boiler did not boil for the entire time when it was turned on for 3-4 hours (it was just a little noisy), and the shutdown automaton never worked (i.e. the water temperature did not reach the desired temperature). Cauldron by the way Evan S2-3 - Mad in Russia. The truth is that I am an electrician, almost like a plumber, but the fact is that I had 2 full days for all the work, since I live in another city for 250 km (and a longer period of time could be sorted out and tested more than once ) And today, when I am at home, everything is ready, no one is already pushing me, and making an analysis of the work done it dawned on me. In the diagram attached to the appeal, in the upper part on the block where the network outlet is, there is a dashed jumper, since it is dashed - this is the key point))), I ignored it. And connected to as shown in the diagram without it. Thus, it seems to me that by simply excluding the 2 remaining wires (black and brown) I did not put the third ten into operation, (there are three in one cup), but connected to the thick white in conjunction with 2 thin blue ones and to the red one in this top block. Question! Do I think in the right direction, and will this jumper save the entire system - which will connect the remaining black and brown wires? And yet, on the diagram there are letters N and A (standing through the nest), but in reality the letters are in the neighborhood - 1 and 2 nests of the block. I connected by letters to N and A, and the two extreme sockets (third and fourth from left to right) are empty. It turns out that I have to insert a jumper in them? Thanks in advance!
