Issue:
CCP3 getting SA sensor failure and RA sensor failure
Resolution:
multiplier is set too high
the rooftop cannot make the static pressure setpoint
the changeover bypass damper stays closed all the time
as the space cools off, the VAVs close
airflow across the coil is too low
SAT gets too cold
set the mulitplier to 1
the rooftop will be able to make the duct static setpoint
the COB will open
the airflow across the coil will be higher
the SAT will not get too cold
