4.4.5 Error Display and RESET
1. When an error higher than Level 2 occurs (the Boiler may
stop operation or only has basic functions), the Boiler enters
<Error Display mode> directly at <Normal Operating mode>
or <Power Off mode>.
2. When an error occurs at other panel modes, only the Error icon
flashes and it enters <Error Display mode> after terminating
the current mode.
3. The Error icon and error code flash alternately at 1 second
intervals at <Error Display mode>.
4. The error code displays 3 digits.
5. Entering Service Info, Error History or Special Parameter mode
is available at <Error Display mode>.
6. When pressing the [Reset] button once while the error code
is displayed, the error will be released after ‘RST’ displays for
3 seconds if the Boiler meets the conditions to release the
error. If releasing the error is not possible, the error code will
display again after 3 seconds.
7. When releasing the error by pressing the [Reset] button once
or it is automatically released at <Error Display mode>, the
Boiler returns to <Power Off mode> after releasing the error,
if the error occurred in a specific mode (Power OFF, Test, or
Parameter Setting mode) .
