When conditions occur that cause unsafe operation or possible damage
to the unit (drain open, low oil level, high temp, etc.), the controller will
halt operation, activate an alarm and display error codes &
messages. Error codes are shown on the
Lower display screen
(red graphic) ... error messages and prompts are shown on the
Upper display screen (blue graphic) . Generally, power to the
heating elements will be shutdown until an error condition has
been corrected. Pressing the
[ALARM] key silences the alarm, but does
not clear the error. Error codes are shown in the table below and
further details are given in the following section.
