The new furnace came to the point that I turned off part of the floor, I reduced the 3-way valve to 3.5 and it was 4.5 and reduced the water temperature to 38 degrees. no effect is used after today. The first thing that this stove reaches is the desired temperature, which is 55 degrees, everything is turned off. it increases to 58.5, it stays on for about 20 minutes, between times the feeding has started, then the temperature drops for about 6 minutes and at 53.9 the feeding starts, the temperature continues to drop, the eco is on all the time, it lasts about 20 minutes, the temperature drops to 44.4 and begins to grow and again the same pattern. Today the complaints were minimal visible ash but I already know that it was a bad eco the first. I am worried if this temperature drops too much. basement temperature 20 and floor 15 and top 20. and if the flame is too low, which value should I increase, I hope I can overcome it somehow but I already feel like burning this stove.
