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.

Disabled/Enabled
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.
D: 30:00 mm:ss
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
2
sensor. The RH and/or CO
2
values could also derate an EI.
R:
0 to 100%
EI Time Satisfied
–
Percentage of
Occupied
time during which a zone maintains an EI of
70% or higher.
R:
0 to 100%
Weighted EI
–
Determines the priority of a zone in an EI roll-up, which must be
completed using a different control program.
