Setting range: -50.0 to 50.0% of the heating proportional
band.

Balance:
Balance is used to pre-position the proportional
band with respect to setpoint. With Balance (MV Offset)
set at 50% the proportional band will be centered around
setpoint. To move the band left or right, decrease or
increase the balance setting respectively.
Setting range: 0-100%

Anti-Reset Wind-up:
Anti-Reset is used to limit the range
where integration occurs. This helps in stabilizing a sys-
tem. With Anti-Reset at 100%, integration will occur
throughout the proportional band. With Anti-Reset set to
90%, integration will occur at 90% of the band above the
setpoint and 90% of the band below the setpoint. Auto-
tuning automatically sets Ar.
Setting range: 0-100% of full scale, set in E.U.

Input type:
The Input Type is the type of sensor to be
used with the controller in sensing the process variable.
The Input Type must be correctly programmed into the
controller in order for the controller to perform with the
selected sensor type. Depending on the type of sensor to
be used, the controller comes in two models. One model
accepts J, K, R, B, S, T, E, N thermocouples and RTDs
(Pt100), and the other model accepts 1-5/0-5V DC and 4-
20/0-20mA DC signals.
The current/voltage model comes with a 250
Ω
precision
resistor. Wired directly to the controller, it converts a
current signal into a voltage signal. There is no need to
