FunctionInstructions:
Press RST keytoopen thethermostat, on the runningstatus, press thiskey
for3seconds, then thethermostat can be turned off.
◆Cooling,heatingfunction:
CoolingMode: Whenthe measured temperatureishigherthan orequalto
the set value+hysteresis, the relaypicks up tostart theoutput; When the
measured temperaturebelowthe set value, therelayoffand closethe output.
Heatingmode: When the measured temperatureishigherthan orequalto
the set value, the relayoff, turnoff theoutput; Whenthe measured
temperaturebelowthe set value-hysteresis, the relaypicks up tostart the
output.
ExampleforSetting:Ifitissettoheatingmode,setthetemperatureto25
degrees, hysteresisissetto5, thenwhenthemeasuredtemperatureis
higherthanorequal to25 degrees,therelay isoff, close theoutput.
Whenthetemperatureisbelow 20degrees, pick uptherelayagain, to
starttheoutput.
ExampleforSetting:Ifitissettocoolingmode,setthetemperatureto25
degrees, hysteresisissetto5, thenwhenthemeasuredtemperatureis

◆Temperaturecalibrationfuntion:
Whenthereisdeviation between the measuring temperatureandstandard
temperature,usethe temperaturecalibrationfunction,makethe machine
measurementsvalue consistentwiththe standardtemperature,theafter
calibration temperature=the beforecalibrationtemperature+calibration value
(calibrationvalue canbe positivenumber, negativenumber, and 0).

toadjust the parameters.
Forexample:Whenwemeasuretheprobetemperaturewas 25degrees,it
