return air temperature input. This input is used to monitor
system functionality and to provide diagnostics on how the
system is operating. This sensor input can be used in place of
the space temperature input. It also acts as a backup in case of
a space temperature sensor failure.
(3) SAT - Supply Air Temperature.
supply air temperature input. This input is used to monitor
system functionality and to provide diagnostics on how the
system is operating.
(4) OAT - Outside Air Temperature.
temperature sensor is factory installed in the unit to monitor
the outside temperature. This temperature is used to control the
economizer.
