Page 54
The Home screen displays valuable information for the given state
of the water heater (standby, demand, or error).
When in demand, the power bar shows the magnitude of the fan speed
within the factory set rate. When the blower, gas, and flame icons are
on, the power bar is synonymous with burner power (100% is Max
Power and 1% is Min Power). If only the blower icon is on, then the
power bar represents pre-purge or post-purge operation. The bolt icon
represents ignitor operation.
The flame signal meter will be green if the magnitude of the current
is acceptable.
If the heater is in error, the type of error, error code, and description
are displayed on the Home screen.
The Status screen contains useful, real-time information pertaining
to fan speeds and sensor values.
The History screen contains useful, real-time information about burner
run time, successful and failed ignitions, and flame failures.
It also gives the option to view blocking and lockout error logs.
The blocking error log displays the history of blocking errors (“E” codes).
The most recent error is shown first with the date and time displayed.
Use the scroll bar to view the error history.
