Point Name/Description Default/Range
Maximum Heating SAT – The value that the SAT must exceed to cause the static
pressure setpoint to be set to the LAT Duct Static Pressure Setpoint . This is also the
Supply Air Temperature Alarm 's high limit.
D:
R:
120°F (48.9°C)
40 to 180°F
(4.4 to 82.2°C)
Minimum Cooling SAT – The minimum low limit value that the SAT must exceed to
cause the static pressure setpoint to be set to the LAT Duct Static Pressure Setpoint.
This is also the
Supply Air Temperature Alarm 's low limit.
D:
R:
45°F (7.2°C)
40 to 180°F
(4.4 to 82.2°C)
Pressure Control Deadband – The amount that is added to and subtracted from the
bypass controlling setpoint (Duct Static Pressure Setpoint or LAT Duct Static Pressure
Setpoint). When the static pressure is within the controlling se/- this value, the
output to the actuator or VFD drive maintains at its current position. When the static
pressure is greater than the controlling se/- this value, the output modulates
accordingly.
CAUTION If this value is too low, the damper may oscillate to maintain the static
pressure. This could cause the actuator to fail prematurely.

LAT Duct Static Pressure Setpoint – The static pressure setpoint that the
controller will maintain if the SAT exceeds the Maximum Heating SAT or
Minimum Cooling SAT value. To disable this function, set this value less than
or equal to the Duct Static Pressure Setpoint .

Locks – CAUTION Overriding these values may damage equipment or
ductwork.
Duct Static Pressure – Allows you to override the static pressure sensor input
for testing and troubleshooting.

O
(0 to .498 kPa)
Target damper position – Allows you to override the normal control of the
damper/VFD for the purpose of testing and troubleshooting.
R: 0 to 100%
