Local BACnet Schedule
Configure ZS Sensors by setting the following options in the Local BACnet Schedule
microblock popup. Click Local BACnet Schedule to access the microblock popup
Properties page > Details tab.
See the microblock Help for more detailed explanations.
Sensor Configuration
Allow Force Unoccupied: – Check to allow a user to save energy by
forcing the zone into an unoccupied schedule on the ZS sensor. The
user does this by holding the sensor's On/Off button for at least 3
seconds. This forced state remains in effect until the schedule
transitions to unoccupied or until a user presses the sensor's On/Off
button again.
Force Unoccupied without Delay: – Check to allow a user to force a zone
to unoccupied immediately instead of the normal 3-second delay.
NOTE This option is not available if Allow TLO Set During Occupied is
checked.
Timed Local Override
Increment: – Minutes that the microblock adds to the zone's occupied
time for each click of the zone's local override button or switch.
Maximum Duration: – Maximum value (up to 960 minutes) the
microblock outputs, regardless of additional pulses from the controller's
input.
Environmental Index
Environmental Index (EI) – Initial Occupied value is 100%. A value of 0% means the zone
is Unoccupied. If the space temperature deviates from Effective Heat Setpoint and
Effective Cool Setpoint range, the value is derated. EI supports an optional RH and/or
CO sensor. The RH and/or CO

EI Time Satisfied – Percentage of Occupied time during which a zone maintains an EI 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.
EI Total Weight – Current EI Weighting Factor used to scale the Weighted EI.
EI Decreased By – Source(s) of an EI value reduction.
Options:
Temp – EI decreased by Space Temperature
Temp & RH – EI decreased by Space Temperature and Relative Humidity
Temp, RH, & CO2 – EI decreased by Space Temperature, Relative Humidity, and CO2
RH – EI decreased by Relative Humidity
RH & CO2 – EI decreased by Relative Humidity and CO2
CO2 – EI decreased by CO2
Temp & CO2 – EI decreased by Space Temperature and CO2
None – No source(s) decreasing Environmental Index value
