Setup Loop Control Parameters
Use these menus to change control parameters for heat and cool outputs
of the selected loop, including:
•
Proportional Band (PB), Integral (TI or Reset), and Derivative (TD
or Rate) settings.
• Output Filter.
• Spread between heat and cool outputs.
The Setup Loop Control Parameters menu looks like this:
NOTE
Both heat and cool outputs have the same menus, so
only one of each menu is explained in the text. The
controller shows both heat and cool menus even if the
heat or cool output is disabled. (See Setup Loop Out-
puts for help in enabling or disabling the heat or cool
output.)
Refer to Tuning and Control section for help in
selecting control parameter values.
