VVT Zone Controller 59
Point Name/Description
Default/Range
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
D:
.
There is a fixed hysteresis of 5%rh for return to normal.
R:
100%rh
45 to 100%rh
Alarm Delay (min/%RH)
D: – Determines the amount of delay before an occupied 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.
R:
5 minutes
0 to 30 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
D:
. There is a fixed hysteresis of 5%rh for return to normal.
R:
100%rh
45 to 100%rh
IAQ/Ventilation Alarm
Occupied High CO2 Alarm Limit
– The value that the CO
2
D:
sensor must exceed to
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.
R:
1100ppm
0 to 9999 ppm
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
2
D:
value and the setpoint plus 15 minutes.
R:
.25 hr (15 minutes)
0 to 1.0 hr (60 minutes)

Supply Air Temp Alarm
is active.
