Setup Loop Control Parameters Menu
Use the SETUP LOOP CONTROL PARAMS menu to adjust
heat and cool control parameters, including:
• Proportional band (PB, or gain), integral (TI or reset),
and derivative (TD, or rate) settings
• Output filter
• Spread between heat and cool outputs
The controller has separate PID and filter settings for heat
and cool outputs. The screens used to set these parameters
are nearly identical. In this section, only the heat screens
are shown and explained. The heat and cool parameters ap-
pear only if the corresponding output is enabled.
See Setup Loop Outputs Menu on page 93 for help enabling
and disabling heat and cool outputs.
Table 4.10 shows the parameters available in the SETUP
LOOP CONTROL PARAMS menu.
