This input network variable selects the compressor/circuit (number 1, 2, 3, 4, 5 or 6) that is interrogated.
The controller returns the information for the selected compressor/circuit. You must rst select a
compressor/circuit then interrogate the selected compressor/circuit. This variable selects a compressor/
circuit for the following variables. See Table 2 on page 21 (Data Points for Chiller Models) to
determine which of these variables will be available. (I32)
