Health Compliance Package – Zone Temperature is outside the acceptable range

Objective/Method/Outcome

Objective: Determines if the zone temperature is outside the set temperature for more than the acceptable time

Method: Checks if the zone temperature is outside the set value for more than 1.5 hours and determines an urgency score depending on the level of variation of temperature from the acceptable range and the amount of time it was outside of the range.

Outcome: Creates an insight and assigns an urgency score.

Applicable System

VAV, HP, FCU, UV, UH, RAD, RHT
