Tune for Duplex Heat/Cool | Honeywell UDC3200 guide

5Initiate Tuning

Lower

Display

Select “DO SLOW” or “DO FAST” in lower display.

Upper display will show a “T” as long as ACCUTUNE process is operating. When process completes, tuning parameters are calculated and lower display will show “NO TUNE” prompt.

ATTENTION

The Accutune process may be aborted at any time by changing the lower display back to “NoTUNE” or by switching the controller into Manual Mode.

4.5.2 Tune for Duplex (Heat/Cool)

Accutune for applications using Duplex (Heat/Cool) control.

The controller must be configured to have two local setpoints unless Blended Tuning is desired (see below). During tuning, the Accutune III process assumes that Local Setpoint 1 will cause a Heating demand (output above 50%), and the tuning parameters calculated for that setpoint are automatically entered as PID SET 1. Likewise, Accutune III assumes that Local Setpoint 2 will cause a Cooling demand (output less than 50%), and the tuning parameters calculated for that setpoint are automatically entered as PID SET 2.

Configuration Check for Duplex

See Subsection 3.5 - Accutune Set Up Group for details.

Make sure:

•TUNE has been enabled

•DUPLEX has been configured to Manual, Automatic or Disabled
