Mynute Boiler Green B.S.I. E
Once the cleaning operation has been completed, using the spe-
cial kit supplied as an accessory, the total hour meter will need to
be reset to zero as follows:
- switch off the power supply
- remove the shell
- turning the instrument panel towards you
- unscrew the two screws of the small cover on the electronic
board to have access to the terminals
- while the boiler is powered up, using a small screwdriver includ-
ed, press the CO button (fig. 9) for at least 4 seconds, to check
the meter has been reset, power down then power up the boiler;
the meter reading is shown on the monitor after the “-C-” sign.
Live electrical parts (230 Vac).
Note: the meter resetting procedure should be carried out after
each indepth cleaning of the primary exchanger or if this latter is
replaced. To check the status of the total hour meter, multiply the
reading by 100 (e.g. reading of 18 = 1800 total hours; reading of 1
= 100 total hours).
The boiler continues to operate normally even when the alarm is
activated.
