Point Name/Description
Space Humidity Alarm
Occ 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.
Alarm Delay (min/%RH)
alarm is generated when the controller transitions to the occupied mode. The delay
time equals this value multiplied by the difference between the sensor RH value and
the occupied RH setpoint plus 15 minutes.
Unocc High RH Alarm Limit – The value that the relative humidity sensor must exceed
to generate a Space 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.
IAQ/Ventilation Alarm
Occupied High CO2 Alarm Limit – The value that the CO
generate an Indoor Air Quality Alarm in the occupied mode if DCV Control is set to
Enable. There is a fixed hysteresis of 100ppm for return to normal.
Alarm Delay (min/ppm) – The fractional portion of an hour determining the amount of
delay before an indoor air quality alarm is generated when the controller transitions to
the occupied mode. The delay time equals this value multiplied by the difference
between the sensor CO

Alarms Displayed on SPT Sensor
Space Temperature Alarm – If set to display, shows the alarm indicator on the SPT Pro
sensor if the space temperature alarm is active.
Supply Air Temp Alarm – Shows the alarm indicator on the SPT Pro sensor if the
Supply Air Temp Alarm is active.
Dirty Filter Alarm – If set to display, shows the alarm indicator on the SPT Pro and SPT
Pro Plus' sensor if a dirty filter alarm is active.
Space High Humidity Alarm – If set to display, shows the alarm indicator on the SPT
Pro and SPT Pro Plus' sensor if the Space Humidity Alarm is active.
Space High CO2 Alarm – Shows the alarm indicator on the SPT Pro sensor if the Indoor
Air Quality Alarm is in alarm.
VVT Zone Controller
– Determines the amount of delay before an occupied RH
value and the setpoint plus 15 minutes.
