Temperature calibration funtion:
When there is deviation between the measuring temperature and standard
temperature, use the temperature calibration function, make the machine
measurements value consistent with the standard temperature, the after
calibration temperature= the before calibration tempe calibration value
(calibration value can be positive number, negative number, and 0) .

to adjust the parameters.
For example: When we measure the probe temperature was 25 degrees,it
displays 25 degrees as the CA is 0, it displays 26 degrees as the CA is 1,
it displays 24 degrees as the CA is -1. This function is generally applied
when the probe can not measure directly the measured object. For
example, we place the probe at the outside of a cup to measure its water
temperature, we need to adjust the CA parameters because of the heat
loss of the cup, so that the display temperature can be in accordance
with cup temperature.
Delay Protection Funtion:
In the cooling mode, the first power on, when the measured value above the
set value + hysteresis value, the machine will not immediately start cooling, it
needs to set the delay time, then the machine can run to start cooling; once the
interval between two cooling is larger than the delay time, the machine
immediately starts cooling, once the interval between two cooling is less than
the delay time, the machine must run the remaining delay time to start cooling.
The delay time is started to calculate from stopping the machine. The delay
time of heating mode is as same as the cooling mode.
Note: It is recommended that only the device that use compressor cooling can
use the delay start function, the user who don't need delay start function
please set this parameter to 0.

Upper and lower limit functions:
The setting of HS and LS limit the set range of control temperature point , for
example: HS is set to +15, LS is set to -10, the control temperature can only be
adjusted between -10 and +15, when the control temperature to -10 then press
"

" key, the display will remain on the status of -10 and not decrease; when
the control temperature to +15 then press "
▲
" key, the display will on the
status of 15 and not incease. If the set point outside this range, it needs to
firstly change the value of HS and LS, then it can be achieved.
Upper and lower limit settings:
