DIGITAL PRESSURESTAT SET UP

A. Some models of this central chiller provide optional digital pressurestats for refrigerant
high and low pressure monitoring and display in lieu of traditional analog gauges.
B.
The digital refrigerant pressurestat is a dual pressure safety switch as well as a current
value refrigerant pressure display that uses transducers with a 0-10v output an in input
source.

C.
In normal running mode the head pressure and
the suction pressure for a single refrigerant zone
is continuously displayed. The small arrows along
the bottom of the display window indicate that
the relay contacts are closed and the system is
functional.
D. When either the head pressure or suction
pressure is measured out of the set point range
the corresponding arrows will disappear. If the
head pressure is out of range the red LED will
come on and the reset button will have to be
manually pushed after the condition has been
corrected.
E.
If the suction pressure is out of range
the system will reactivate automatically
after the pressure rises above the
differential value.
