Compressor
Operation
mode
0: the compressor is only working in a
discontinuous type.
1: compressor according to the value of CP (see
below) to determine the balanced or intermittent
work of the compressor.
2: compressor according to the value of Htd (see
below) to determine the balanced or intermittent
work of the compressor.

(according to the ambient temperature and set
value);

point
When "temperature set value
≥
Cnp", the
compressor is prohibited from working.
Note: This mode of operation has the highest
priority, that is, the controller executes this
command first, and then judges the balanced or
intermittent operation of the compressor.
