P18.10
Setting
temperature
compressor runs stably, the fan speed is
controlled by thermostatic PID ( P18.42 =0),
PID calculation is carried out via P18.10 and
the machine head temperature to realize
thermostatic control.

P00.04 (upper limit of running
frequency)
During regulating, if the pressure exceeds
the set working pressure but lower than the
unloading pressure, the allowed min.
working frequency is P18.11.

○
P18.13 No-load delay
When sleep function is valid, after unloading,
the VFD runs at no-load frequency in the
time set by P18.13 , and then enters sleep
state.
When air consumption quantity is small,
users can enable sleep function; if sleep
function is valid, it is necessary to lower
down P18.13 to make the device enter sleep
state quicker.

○
P18.14 Stopping delay
After the stopping command becomes valid,
the VFD will first run at no-load frequency in
the time set by P18.14 , and then stops.
Setting range: 0

○
P18.15 Loading delay
Loading operation is available only after the
motor runs at no-load frequency in the time
set by P18.15 .
Setting range: 0

○
P18.16 Restarting delay
After the system stops, it is necessary to wait
until the time set by P18.16 elapsed before
restart.
