END/ Heating problems
This code indicates if after 72 hours of continuous heating operation, the system will hibernate
automatically.
The defect reason could be heater or a problem with PCB.
1) Before starting the test, ensure that the terminals (9&10) and (11&12) are properly paired up
and not swapped with any other terminal. From left to right, the number of the terminal should be
10,9,11,12. If the number is missing you can also test by measuring the AC voltage on the PCB
with a multimeter. Set the multimeter, turn the power on and run the heater function for 20 seconds.
Test terminals (9&10) then (11&12) and look for voltage reading equal the wall voltage.
Please refer to

or consult a professional electrician for how to use the multimeter.
