The optional RH and/or CO2 values derate the EI value when they deviate from their setpoints.
•
If RH Control is set to Enable, the EI is derated when the RH value is less than the EI Humidity Low Limit or
when the RH value is greater than the Occupied RH Control Setpoint.
•
If DCV Control is set to Enable, the EI is derated by CO2 if the value exceeds the DCV Max Ctrl Setpoint.
If a zone is Unoccupied, the EI will calculate a value of 0%.
EI Time Satisfied is the percentage of Occupied time which a zone maintains an EI value of 70% or higher.
Weighted EI determines the priority of a zone in an EI roll-up, which must be completed using a different control
program. The value is determined by multiplying the real-time EI value by the EI Weighting Factor.
