Alarm High/Low Limit Setting (AH, AL)
•
When measured temperature is higher or equal to AH,
high temperature alarm will be triggered, buzzer will
alarm with
flash until the temperature is lower than AH
or any key is pressed.
•
When measured temperature is lower or equal to AL, low
temperature alarm will be triggered, buzzer will alarm
with
flash until the temperature >AL or any key is
pressed.
•
Temperature Calibration CA
•
When there is deviation between measured temperature
and actual temperature, we can set
CA
value to align
measured temperature and actual temperature. The
corrected temperature = measured tempe
CA
5. Error Description
•
Heater or cooler does not turn on when specified
temperature is reached?
•
Check the Ld value you set. Recheck where you put the
sensor. Also check if you set PL. It will make the cooler
output delay
•
The screen display HHH or LLL?
•
HHH means the temperature sensor short circuit. LLL
means the temperature sensor open circuit. Buzzer will
alarm with
flash. Press any keys can’t stop alarm. You
need to check the sensor or replace it.
Warning:
•
The sensor probe is waterproof, but the controller is not
waterproof. Keep the controller away from water.
•
In each output socket, we use high quality 16A relay
instead of 10A relay in order to improve the performance
in case of overloading.
•
In order to let controller work under high performance
condition for a long time. We recommend to use max
power
≤
1100W when you use resistive load such as
heating rod, heating pad, electric water heater etc. use max
power
≤
275W when you use inductive load such as
compressor , pump etc.
