I recently purchased a PID, WS1510DPS.  My unit seems to be working as designed.  It takes the pot to the desired temp and holds it there.  However, the alarm light is on and it beeps every few seconds.  The display flashes between the current pot temp and the code "AH".  I'm unable to find a reference to that code in the instructions.  The beep is driving me nuts.  This can't be normal, so what am I doing wrong and how do I turn it off??

Any help would be appreciated.
Thanks

AH is high temperature alarm. When your probe temperature is too high, you will see this code. For WS series controller, AH parameter is located in 188 menu. For details, please see its operation manual.

Thank you for the response.  Very helpful.  I'll reset that.
