Monitors the digital outputs of the unit controller for
diagnostic purposes. Each item is reported as a bit so
that multiple outputs can be viewed simultaneously. The
Present_Value reflects the first status bit (b0), which is the
“Compressor #1” state. All the status bits are returned in
the BV2.description property, high bit on the left and low
bit on the right. Example: 0000000000000001 indicates
that the compressor #1 output is active. Array index NULL
