Point Name/Description
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.
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.
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.
IAQ/Ventilation Alarm
Occupied High CO2 Alarm Limit – The value that the CO
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.

Unit
Occupancy Status – The controller's occupancy status as determined by a network
schedule, a local schedule, or a timed override.
Pre-Occ Purge – Indicates if the pre-occupancy purge cycle is 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
Range.
Effective Heat Setpoint – The current heating setpoint. May include offsets from
configured occupied/unoccupied setpoints resulting from Optimal Start to Demand
Limit.
Effective Cool Setpoint – The current cooling setpoint. May include offsets from
configured occupied/unoccupied setpoints resulting from Optimal Start to Demand
Limit.
System Cooling Demand Level – The demand limit used by the control in cooling mode.
System Heating Demand Level – The demand level used by the control in heating
mode.
