Error codes
Error codes can be used to assist in diagnosis of why the fire will not operate correctly.
They appear if the control detects abnormal conditions, either in environment, in installation or components / internal electronics. (If you do not have a handset with a display that shows the error codes, then checking for the faults is still valid. The
illumination of the red indicator light shows the valve is in error).
Note : To reset any error code, press and hold the power button 
on the valve.
False errors can be reported if the batteries are faulty or lack enough power to correctly operate the valve.
