RTD Lead Wires
0x4nn1

0x11
Sets the number of lead wires for RTD type
inputs to 2 or 3 wires.
Input Calibration Offset/Bias
0x8nn0
0x6D
0x23
Allows the system to offset the input reading to
compensate for system errors.
Process Scaling High
0x8nn0
0x6D
0x18
The process value corresponding to the high
electric value for process input 10V or 20mA.
Process Scaling Low
0x8nn0
0x6D
0x19
The process value corresponding to the low
electric value for process input 0V, 4mA, or
0mA.

Description
Heat Proportional Band
0x8nn0
0x6D
0x26
Sets the heat gain as a proportional band.
Increase reduces gain and increases stability.
Decreasing increases responsiveness.
Integral Time
0x8nn0
0x6D
0x27
Sets the rate the power increases or decreases.
This will pull the temperature to set point. A
low value integrates power quickly but can
cause instability.
Derivative Time
0x8nn0
0x6D
0x28
Sets the derivative time constant. Reacts in
opposition to changes in the process. Unless
the system has significant lag, this value should
be kept low or even zero.
Cool Algorithm
0x4nn1
0x68
0x12
Cooling action is Off, PID, or On/Off
Cool Proportional
0x8nn0
0x6D
0x29
The gain of the cooling part of the control loop.
This is in effect if the cool mode is PID.
Cool Hysteresis
0x4nn1
0x68
0x13
If the cool mode is ON/OFF this is the switching
hysteresis.
Dead Band
0x4nn1
0x68
0x2A This is the space between the heating and the
cooling regions to keep the system from
oscillating continuously between heat and cool.
It can also be set to a negative value so the
