After maintenance, if the value is left on 0 the
maintenance symbols will not disappear but
instead continue to flash, as they did prior to
maintenance.
The remaining months until maintenance will
be replicated in read only in the 'info' section
under value J15.
N.B.: The flashing symbol in Fig. 9.5 is not an
error. The boiler continues to run normally but
it indicates the expiry of the maintenance pe-
riod.
