Suction Groups Section

The first section of the RX Home screen is the Suction Groups section located in the top left corner. The large let- ters have the name of Suction Group 1 along with infor- mation on compressor stages active, and the current pressure setpoint. Setpoints, status, percentages of capaci- ties, and which stages are active for each suction group are displayed as well. The suction group that is displayed in the large block at the top left of the screen is the group that is named alphabetically first of the suction groups.

OAT Section

The upper-left hand section of the BX Home screen contains status information for four different values, including outside air temperature, humidity percentage, season, and light level.

Demand Control Section

Directly below the OAT section is demand control sta- tus information, which shows the number of applications and number of loads being shed.
