A setting of ONOF allows the control to operate as a
simple on/off mode. This setting forces the control to
turn off at set point, and on at the set point plus the
differential (SP_d). When selected, the Out1/OnOF
menu item is followed by ####/SP1d, and the tunE, Pb,
rES, OFS, rtE, and ArUP selections in the Secondary

SP_d Set Point On-Off Differential (hysteresis). Se-
lect 1 to 9999 (direct acting), or -1 to -9999
(reverse acting). This value will be negative for
reverse acting set points, and positive for direct
acting outputs. Set the value for the amount of
difference between the turn off point (set point)
and the turn on point. The following drawing
shows output behavior for reverse and direct
action.
