DIFFERENTIAL: This is used to indicate to the logic board (non 0-10VDC mode) how tightly to
maintain boiler target temperature. It must be noted that the lower the value used, the more boiler cycling
will occur. This has direct relation to life span of the boiler contactors and other components.
MAX STAGES: This is typically a factory setup screen, as the boiler is manufactured, we indicate to the
logic board the amount of stages it has to work with (4 – 15 stages depending on boiler kW).
FACTORY RESET: To reset the boiler back to its factory settings, use this setting.
 NOTE the boiler will reset, if boiler is active while you reset it, it will shut down and restart.
