The core set of modules created for all Heat Pump applications provides the zone temperature setpoint and base heating/cooling sequencing logic. Specific selections in the Heat Pump selection tree provide the required Inputs, Outputs, and Network Input connections for the core logic set and integrate the specific Output Controller options for Fan Logic, Heating, and Cooling Coils.

The following is the list of modules created by the core logic:

Network Inputs

  • SYSTEM-MODE: This module is a Network Input for the System Mode Determination State Generator used to force the unit into a mode of operation .

  • TUNING-RESET: This module is used to reset the tuning parameters to the default values present after the initial application transfer to the device.

See the Network Input Modules section.

Miscellaneous (Inputs)

  • MAD-% (Mixed Air Damper Effective Command): This module reads the effective command and priority of the associated damper output.

See the Miscellaneous Input Modules section.

Setpoint/Miscellaneous

State Generation

  • Damper Override Check (Analog Override Check): This module monitors the current command and the command priority of the output. If an output is overridden, the Output Controller is turned off to prevent PID windup and improper tuning.

  • Heat Pump Override Check 01 (Binary Override Check 01, 04, and 08): This module monitors the current command and the command priority of the output. If an output is overridden, the Output Controller is turned off to prevent PID windup and improper tuning.

  • 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.

  • System Mode Determination: This module separates out the Water Flush system mode for separate connection to State Selection and passes the remaining system modes to State Selection.

  • Zone Sequencing (FC) (Occupied Sequencing): This module manages the transition between heating and cooling output controllers and determines which device should be operating to control the space temperature.
