Options Description
Indicates the I/O Expansion input(s) for which the following configuration
applies. All selected inputs are averaged to determine the input reading used
by the PID output.
Any Specifies the name displayed on the Appliance Status Screen representing the
I/O Expansion PID output.
Any Specifies the PID Input reading that the system attempts to maintain.
Any Specifies the proportional term used by the I/O Expansion PID algorithm.
0 min – Any Specifies the integral term used by the I/O Expansion PID algorithm.
0 min – Any Specifies the derivative term used by the I/O Expansion PID algorithm.
0 sec - Any Specifies the time between samples for the I/O Expansion PID algorithm.
Any Specifies the range above and below the input Setpoint within which the I/O
Expansion PID integral error accumulates.
Direct Specifies that the I/O Expansion PID output increases as the input increases.
Reverse Specifies that the I/O Expansion PID output decreases as the input increases.
Auto The I/O Expansion 4-20 Output is modulated automatically by the I/O
Expansion PID algorithm based on the configured PID settings above.
Manual The I/O Expansion 4-20 Output delivers a 4-20mA signal in accordance with
the configured Manual Output setting below.
0 % - 100 % Specifies the I/O Expansion 4-20 Output signal when in Manual Mode.
0 % - 100 % Specifies the I/O Expansion 4-20 Output signal when the controller is stopped.
0 % - 100 % Specifies the lowest possible output value for the I/O Expansion 4-20 Output.
0 % - 100 % Specifies the highest possible output value for the I/O Expansion 4-20 Output.
