Whenever the burner turns off, the turn-on threshold is lowered
by doubling the on hysteresis, and then increasing it by 2
degrees F per step until it reaches its original value.
The time of each step is provided by the hysteresis step time
parameter. The number of steps required to reach the original
on hysteresis is the on hysteresis value divided by
2 degrees F.

Setpoint and Hysteresis (Steam
Control)
The Steam and LL master each have similar setpoint and
hysteresis functions. The parameters for each are separate
and independent.
Whenever the burner turns on, the turn-off threshold is raised
by 10psi (1.0 for 0-15 psi), and then it is decreased in steps.
The time of each step is provided by the hysteresis step time
parameter. If the time (T) is not-zero, then the following
schedule is followed until the off threshold reaches its original
value:
Whenever the burner turns off, the turn-on threshold is lowered
by doubling the on hysteresis, and then increasing it by 2 psi
(.2 psi for 0-15 psi) per step until it reaches its original value.
The time of each step is provided by the hysteresis step time
parameter. The number of steps required to reach the original
on hysteresis is the on hysteresis value divided by 2 psi per
step for (0–150 PSI .2 psi per step for; 0–15 PSI).
