Compressor minimum capacity enabling / unloaded compressor start
0 = Enables minimum power only at compressor start-up (start-up with
minimum capacity / idle running valve in OFF with compressor off )

control mode (start-up with minimum capacity/idle running valve in OFF with
compressor OFF)

start-up (start-up with minimum capacity / idle running valve in ON with
compressor off )

and in temperature control mode (start-up with minimum capacity/idle running
valve in ON with compressor off )
