OUTP works for refrigerating, and AUX works for heating.
In a bidirectional system, OPL for define the limitation of maximum cooling output. So,
when the OPL= -100%, means no limitation on cooling output. If set OPL=-110%, it
can made current output excess 10% on maximum output. When the output type is
SSR output or relay output, maximum of cooling output should not set more than
100%
OPL limits the maximum of OUTP (main output) when PV<OEF. OPH should be
greater than OPL.
When PV<OEF, the upper limit of OUTP is OPH; when PV>OEF, the upper limit of
OUTP is 100%.
For example, to avoid that the temperature raises too quickly, under 150℃, a heater
can work only under 30% of power, then we can set OEF=150.0 (℃), OPH=30 (%)
In the same communication line, different instrument should be set to different
address.
The range of baud rate is 1200～19200bit/s. When COMM/AUX slot is used as AUX,
bAud should be set to 0.
