Point Name/Description
DCV Max Vent Airflow – The maximum airflow allowed when the IAQ function overrides
the temperature control. When active, the damper modulates to the temperature
control requirement or the DCV Max Vent Airflow, whichever is greater. This value is a
percentage of the Maximum Cooling Airflow Setpoint.
Filter Service Alarm Timer – Fan type terminals only. The amount of time the fan will
run before generating a Filter Alarm. Set to 0 to disable the alarm.
T55 Pushbutton Override – Enables or disables the use of a pushbutton override from a
local space temperature sensor.
Setpoint Adjustment – Enables or disables the setpoint adjustment mechanism on the
local space sensor.
Setpoint Adjustment Range - The maximum amount that a user can adjust the setpoint
on the local ZS or SPT sensor.
Heating Lockout Temperature – Supplemental reheat is disabled if outside air
temperature exceeds this value. Supplemental reheat is enabled when the outside air
temperature falls below a fixed hysteresis of 2 °F (1.1 °C). This function is active only
if there is a valid network outside air temperature.
Power Fail Restart Delay – How long the controller delays normal operation after the
power is restored. This is typically used to prevent excessive demand when recovering
from a power failure. Applies to Series Fan start delay when system mode transitions
from unoccupied to occupied. A delay of no greater than 120 seconds is recommended
for Series Fan applications.
Occupancy Schedules – If Enabled, the controller stores and follows a schedule sent
over the network or programmed locally through a touchscreen or Field Assistant. If
Disabled, the controller occupancy is controlled from the BAS On/Off or System
Occupancy network point.
Occ Override Delay – The amount of time the controller remains occupied after the
remote occupancy switch returns to the unoccupied position.
