KODE routine library

Cloud BMS includes a pre-configured library of FDD routines that cover common fault conditions across airside, chilled water, and hot water systems. These routines are ready to deploy and can be customized through parameter tuning.

Routine structure

Every library routine shares a common structure. Each routine includes a priority level, a fault domain, and a set of tuning parameters with default values. Priority assigns a severity level to each routine. The five levels are Life Safety, Critical, Warning, Alert, and Info. Domain groups routines by the type of fault they detect. Domains include Cooling Operation Failure, Heating Operation Failure, Air Quality, and AHU Fan / Pressure Issue. Parameters control the thresholds and delays that determine when a routine triggers an event. You adjust these values during configuration to match your equipment and site conditions. Common parameters across most routines include:

Parameter	Description
`Alarm On Delay`	Time a condition must persist before the routine generates an event
`Start Delay`	Wait time after equipment starts before the routine begins monitoring
`Return to Normal Delay`	Time a condition must clear before the routine closes the event
Tolerance / threshold values	Deadbands and delta values that define acceptable operating ranges

Airside faults

Airside routines monitor fan coil units, VAVs, and air handling units for cooling, heating, air quality, and fan or pressure faults. Parameters in each routine are color-coded by category:

Timing Delays that control when the routine generates or closes events
Threshold Equipment-specific thresholds, positions, and delta values
Deadband Setpoint deadbands, tolerances, and arbitrary setpoints
