Determine if boiler is operating when OAT is above boiler enable set point
Applicable Systems
Primary: BLR
Objective/Method/Outcome
Objective: Determine if the boiler is operating when a heating plant may not be required.
Method: Check if the boiler is enabled above the desired OAT threshold.
Outcome: An insight is generated if the boiler is enabled for more than 4 hours while the OAT is above its enable threshold of 30 degrees.
Logic
This rule sums the number of times the boiler is operating above a given OAT threshold. Since the aggregation interval is set to 15 minutes, every time the control loop is outside of range is treated at 1/4 of an hour.
Sum over a week(number of 15-minute intervals system is operating above given OAT)
Determine if boiler is operating when OAT is above boiler enable set point
