Range Note 1: This is a count value, 0 to 255, representing degrees F, in integer
format. In the Modbus case, use Low-Range = 0, and High-Range = 255.
Range Note 2: Actually, the Trane equipment used percentage points, which are sent
back as 0 to 100 counts representing 0 to 100 percent, in integer format, of the VAV
box’s maximum flow rate. This is then translated to CFM (cubic feet per minute),
given the scale associated with the box (see AI/AO #9, the CFM maximum of the
box, commonly called the “box size). In the Modbus case, use Low-Range = 0, and
High-Range = maximum box size.
In the first two columns, the first part is the Modbus Register number. The second
part is the BACnet object instance number.
