Space Humidity Alarm
Occupied High RH Alarm Limit
– The value that the relative humidity sensor must
exceed to generate a
Space Humidity Alarm
in the occupied mode if
RH Control
is set
to
Enable
. There is a fixed hysteresis of 5%rh for return to normal.
D:
R:
70%rh
0 to 100%rh
Unoccupied High RH Alarm Limit
– The value that the relative humidity sensor must
exceed to generate a
Space Relative Humidity
alarm in the unoccupied mode if
RH
Control
is set to
Enable
. There is a fixed hysteresis of 5%rh for return to normal.
D:
R:
100%rh
0 to 100%rh
Low RH Alarm Limit
– The value that the relative humidity sensor must drop below to
generate a
Space Humidity Alarm
in either the unoccupied or occupied modes if
RH
Control
is set to
Enable
. There is a fixed hysteresis of 5%rh for return to normal.
D:
R:
30%rh
0 to 100%rh
IAQ/Ventilation Alarm
Occupied High CO2 Alarm Limit
– The value that the CO
2
sensor must exceed to
generate an
IAQ Alarm
in the occupied mode. There is a fixed hysteresis of 100ppm for
return to normal. Requires a valid
Indoor Air Quality CO2
sensor value and
IAQ Control
is set to
Enable
.
D:
R:
1200ppm
0 to 9999 ppm

Occupancy Status
– The controller's occupancy status as determined by a network
schedule, a local schedule, or a timed override.
R: Unoccupied/Occupied
Pre-Occ Purge
– Indicates if the pre-occupancy purge cycle is active.
R: Inactive/Active
Setpoint Adjustment
– Indicates the amount of offset applied if you configured the
space sensor as a type of T56. Set the display value range in
Setpoint Adjustment

Demand
Limit
.
R: _°F/C
Effective Cool Setpoint
– The current cooling setpoint. May include offsets from
configured occupied/unoccupied setpoints resulting from
Optimal Start
to
Demand
Limit
.
R: _°F/C
System Cooling Demand Level
– The demand limit used by the control in cooling mode. R: 0 to 3
System Heating Demand Level
– The demand level used by the control in heating
mode.
R: 0 to 3
