Autotune the controller for heat only and then manually tune the
cooling parameters.
Wiring and Setting
1. Make sure the correct output type is installed for Output #2. Verify
that parameters TC2, COOL, and db are indicated in the System
menu.
2. Wire your cooling load to the Output #2 terminals located on the
back of your controller.
3. In the Setup menu, program the correct code for Heat/Cool action.
See Table of Output Type Codes.
4. In the System menu, program TC2, the cycle time for
Output #2. The table below is a general guide to TC2 settings.
5. Autotune or manually tune the PID parameters of your
controller. Autotune will work for the heating PID parameters
but not on the cooling parameters. You must manually tune the
cooling parameters.
