OT @ 0°F SP: When operating this Electro Industries Industrial Boiler in outdoor reset mode (outdoor
sensor connected upon power-up), set this value to your desired set point output water temperature when
the outdoor temperature is 0°F. As the outdoor temperature fluctuates, the output water temperature
desired with shift in an attempt balance the boiler output with the heat load requirement of the space.
 RANGE 40°F to 195°F.
 Factory Default: 155°F
MIN HI MASS: If the application has a requirement for OT @ 0°F SP to be less than 160°F, the
application is considered to be high mass (concrete slab, for example). MIN HIGH MASS setting is then
used to set the minimum value for the boiler to target based on the outdoor temperature.
 Range: 70 – 110°F
 Factory default is 90°F
MIN LO MASS: If the application has a requirement for OT @ 0°F SP to be greater than 160°F, the
application is considered to be low mass (baseboard heat, for example). MIN LOW MASS setting is then
used to set the minimum value for the boiler to target based on the outdoor temperature.
 Range: 120 – 140°F
 Default: 120°F
