remains inactivated.
B - Reading reaches above High Setpoint but below (Hi SET +
½ Hi HYS), Hi-Set relay remains inactivated.
C - Reading reaches between (Hi SET - ½ Hi HYS), the Hi-Set
relay remains inactivated.
D - Reading reaches above (Hi SET + ½ Hi HYS), and the Hi-
Set relay is activated.
E - The Hi-Set relay is inactivated only when the reading falls
below (Hi SET - ½ Hi HYS).
F - Reading reaches between (Lo SET - ½ Lo HYS), the Lo-
Set relay remains inactivated.
G - Reading reaches below (Lo SET - ½ Lo HYS), the Lo-Set
relay is activated.
H - The Lo-Set relay remains activated until the reading goes
above the (Lo SET + ½ Lo HYS)
