Note 10: If Only 1 Transducer is fitted and the controller is set to a single section type, for example Pack, then

Display 1 will show the current suction pressure but Display 2 will show Ft. Transducer input 2 is on by default to

allow for the fitment of a transducer for monitoring purposes. If this probe is not fitted then set the parameter

“Trans2 Span” to 0. This will clear the fault alarm.
