The BMS Listing has the following characteristics:
• All values are integers.
• Some of the values like temperatures and pressures
have an implied decimal place; this means that a value
of 450 read from the chiller via BMS interface for Chiller
Outlet Temperature, CHIL_OUT_04, means 45.0 °F (in
imperial configuration).
• Some values are enumerated integers:
– Chiller State:
