3.4 FAULTS

The heater is equipped with an advanced self-diagnostic
system. If a problem arises with the unit, the fault symbol
will flash on the screen and the respective code will be
displayed.
Some faults, identified with the letter "A," will block unit
operation.
To restore operation, simply press the RESET key (4 -
fig. 1) for 1 second. If the heater does not reset, the fault
must be resolved.
Faults identified by the letter "F" cause temporary blocks
that are automatically resolved when the value returns to
the heater's normal operating range.
