6.4 Control Function Description
When the controller is working normally, the controller will automatically
select the smaller temperature value of the two settings TS1 and TS2 to start
the heating, and will stop heating when the temperature reach the larger one
(the minimum absolute value of TS1 and TS2 is 0.3 °C or 0.5°F), PV displays
the current temperature measurement value, and the SV displays the
temperature at which heating stops.
6.5（ AH,AL） High/Low Temperature Alarm
When measured temperature ≥the setting value of high temperature AH, it will
alarm and turn off heating output. The screen will rotate to display“AH”and
current temperature, buzzer will ”bi-bi-Biii”, until the temperature < AH, buzzer
will be off and return to normal display and control. Or press any button to
only turn the buzzer alarm off.
When measured temperature ≤ the setting value of low temperature AL, it will
alarm. The screen will rotate to display“AL”and current temperature, buzzer will
“bi-bi-Biii”, until the temperature > AL, buzzer will be off and return to normal
display and control. Or press any button to only turn the buzzer alarm off.
High and low temperature alarm will be pushed to mobile APP and remind
the customer that the product is in alarm state.
6.6ContinuousHeatingTimeAlarm(CT)
When measured temperature ≤ the starting heating temperature, the output

control is turned on. If the continuous heating time arrives, but the measured
temperature has not risen to the stop heating temperature, at this time the
heater is abnormal or the probe is abnormal, and the output is forcibly turned
off. PV will show E5, the buzzer keeps ringing, and the alarm status is pushed
to the mobile APP to remind the customer that the product is in an alarm state
and need to check in time.
6.7（CA） Temperature Correction
When the measured temperature deviates from the standard temperature,
the temperature calibration function can be used to calibrate the measured
value consistent with the standard value. The calibrated temperature = the
measured temperature value + the calibration value.
6.8SelectionbetweenDegreeFahrenheitandDegrees
Celsius
Support setting Fahrenheit or Celsius. The default temperature unit is
Fahrenheit. If you need to display the unit in Celsius, please set the CF to C
and note that when the CF is changed , all setting values will be restored to
the default setting and the buzzer will beep once.
7.1AbnormalTemperature
The temperature difference between the two temperature probes is greater
than or equal to 3℃/5℉
7.2ProbeAbnormal
Either the probe is not plugged in properly,or there is a short circuit inside or
inside the probe.
Note:
When the product is abnormal, the PV will show as follows:
Er: Both probes have problems at the same time
E1 or E2: Temperature Probe Abnormal
E4: The temperature difference between the two temperature probes is
greater than or equal to 3℃/5.0℉
E5: Continuous Heating Time Alarm
