Honeywell UDC3500 - 1.2 Operator Interface

Introduction
6 UDC3500 Universal Digital Controller Product Manual 3/07
Heat/Cool (Duplex Tune) will automatically tune both the heating and cooling
sides of the process.
Fuzzy Logic—This standard feature uses fuzzy logic to suppress process variable
overshoot due to SP changes or externally induced process disturbances. It
operates independently from Accutune III™ tuning. It does not change the PID
constants, but temporarily modifies the internal controller response to suppress
overshoot. This allows more aggressive tuning to co-exist with smooth PV
response. It can be enabled or disabled depending on the application or the control
criteria.
* The Second Current Output option is mutually exclusive with the Ethernet
Communications option.
†
Characterizers are mutually exclusive with Setpoint Program #4.
