Heating curve
The AM10 has a built in linear heating curve that sets the supply
water temperature in relation to the outdoor temperature.
Top of heating curve represents the water temperature at 14°F
(-10°C) outdoor temperature. Based on type of heating system
different water temperatures are recommended for bottom of
heating curve. The boiler follows the heating curve in the AM10
up to the maximum supply water temperature set on the boiler
dial which works as a high limit. In addition the warm weather
shut down (WWSD) turns the heating system off when the
temperature outdoors rises above a certain value.
