a. Idle results should be measured with the door closed and represent the total idle energy consumed by the machine including all tank heater(s) and controls. Internal or external
booster heater energy consumption shall not be part of this measurement unless it cannot be separately monitored. b. GPR = gallons per rack; GPSF = gallons per square foot of rack; GPH = gallons per hour; x = square feet of conveyor belt (i.e., width × length)/min (max conveyor speed).

a. P = pan capacity, the number of steam table pans the combination oven is able to accommodate as per ASTM F1495-14a.
c. Automatically identify HVAC system faults using algorithmic-based analysis that performs rule-based,
time-series trend-based, statistically based, or model-based diagnostics, including (where applicable) identification of, at a minimum, the following faults that affect energy performance:
-
Simultaneous heating and cooling above an expected threshold or short-term cycling between heating and cooling
-
System operation outside of scheduled hours above an expected threshold
-
Air or fluid flows not modulating when designed to be variable
-
Significant changes in energy use as a function of ambient or other conditions
d. Automatically provide authorized personnel with prioritized recommendations for fault repair of identi fied faults based on estimated excess energy consumption or cost of non- repair.
e. Be capable of transmitting the prioritized fault repair recommendations to remotely located authorized
personnel.
