    Do you have a tankless coil in this boiler? or should I say does it provide your domestic hot water? If so hopefully it has a mixing valve.

    The high and low

    the high and low is determine by what is required for your system. I always install systems to have a high of 180 or less and low 0f 160 or less. on this boiler a temp below 140 can can cause condensation issues. If you have a tankless you may need to go with 190 for your high but then a mixing valve should be added to the tankless to protect against burning water tempts at your faucets. If your system is stingy on emitters then you would need to run up to 190 or even 200 but this simply wastes fuel for a properly installed system. The amount of baseboard is not enough, unless it is high capacity, to take all the heat the boiler can make. What is the heat loss of the dwelling and what is the amount of baseboard per square foot of dwelling?

    The lowest setting that adequately meets your needs.

    160 low-180 high is a good staring point
