16 OPERA TION Occupancy Determination — The O MNIZONE™ controller can determi ne occupancy in many ways. Local occu- pancy is dete rmined by either a local schedule containe d in the CC6400 controller , the use of the ROCC discrete input point or by sett ing the L ocal/O ff/Remot e switc h to Local .
17 COMRES triggers the compressor staging routine that controls the number of compressors energized. Units are equipped with 4 compressors piped in s eparate refrigerant circuits, and staged On/Off in a fixed sequenti al manner (compressor no. 1 through compressor no.
18 Units not equipped with a water economizer ca n be ordered with the r everse/hea d pressure control valve fact ory install ed and a pressure transduce r located in t he discharge line of compressor no.
19 LOW -PRESSURE SWITCH ( LPS) — T h e L o w - P r e s s u re Switch is loca ted i n the sucti on refrige rant line of each compressor , and is set to open a t pressures below 27 psig. It is wired in the 1 15 va c control power line of the compressor contactor (in seri es with the HPS and EFS), and activates the COL board (above) when it opens.
