All Mixed Air Dual Duct Applications use the core logic listed as follows:
Network Inputs
-
APP-MODE (Application Mode)
-
TUNING-RESET: This module is used to reset the tuning parameters to the default values present after the initial transfer to the device.
See the Network Input Modules section.
Inputs
-
CD-T (Cold Deck Temperature)
See the Input Modules section.
State Generation
-
Mixed Air Start Stop Sequencing (Start Stop Sequencing (AHU Mixed Air)).
-
Application Mode Determination: This module separates out the Water Flush application mode for separate connection to State Selection and passes the remaining application modes to State Selection.
-
Water System Flush Pass Through (Pass Through): This module passes the Water Flush system mode to a separate State Selection input so that when water flush is requested, the valves always open.
-
Mixed Air Cold Duct Sequencing (Occupied Sequencing (AHU MADD))
-
PID Tuning Reset: This module forces every output controller to reset the Proportional Band and Integral time of every PID to default values based on current process ID.
Output Control
-
Heating Required LV (Last Value (Boolean, Enum, Float))
-
Cooling Required LV (Last Value (Boolean, Enum, Float))
