I am getting ready to fire this thing up (finally).
The settings for the A350 set the temp in the boiler. I am going to set the main dial to 180. Inside the blue cover is a dial. I assume this is the offset temp for the boiler. So if I set it to 20 degrees, when the temp in the boiler drops below 160, the boiler starts stoking.
The S350 is the overheat. This is the one that has me confused. Inside the cover there are 2 white dials. One says OFFSET with a range of 1-30. The other says DIFF, with a range of 1-30 as well.
How do I need to set up this S350?
Thanks.

Diff-15 Offset -10 Thats what I started at but I have my A350 setting at 160 for domestic hot water. Now my S350 kicks in at 185 degrees if I crank the feeder up and shuts down at 175 or anyway it is set up to but real world accuracy is more like 170 shutdown after the dump zone if you watch the temp gauge. I am learning the system myself and those numbers is what I started at an have left them there till I need more heat in colder weather.
