DX -> ES Delay: Once the compressor turns off, the damper will continue to be
fully open for this time setting to make up for lost cooling capacity. After the time
expires, the damper will return to temperature modulation. Range of adjustment is
0 to 60 mins with a default setting of 5mins.
DX Assist: The number of compressors that may assist the Airside Economizer
cooling when it is in the E/S Available mode. Choices are: None, 1 (default), 2 or 4
compressors. Note: All compressors may run when not in the E/S Available mode.
Pr Atmosphere: This setting allows for altitude correction in enthalpy calculation.
Range of adjustment is 600 to 1100 millibar with a default setting of 1000mBar
which is accurate at sea-level.

Band: This setting determines the sensitivity of the algorithm. The smaller the
band, the more the algorithm will try to correct the error. If the band setting is too
low, the damper actuator may oscillate by being over-responsive. If the band
setting is too high, the damper actuator may lack responsiveness. Ideally,
the band s et t i ng s hou ld be as lo w a s possible without causing oscillation. In
proportional mode, modulation will be 100% when temperature equals setpoint +
band. Range of adjustment is 0.5 to 25.0°F with a default of 2.5°F.
Integration Time: Used to incrementally change the damper modulation as a
result of an error between set point and the measured temperature. The higher the
Integral time setting is, the slower damper modulation will be changed. If the
Integral time is set too low the damper actuator could change quickly, causing
oscillation. If Integral time setting is too high, the damper actuator may become
sluggish to change. A setting of 0s puts the algorithm in a proportional only mode,
without integral error correction. Range of adjustment is 0 to 999s with a default of
500s.
