Checks During And After First Start-Up - Beretta POWER PLUS Installation Instruction

When the boiler is in Standby, the display on the Master
unit is in Readout mode and the three digits show the
number "1", followed by the value of the outlet tempe-
rature. The green LED (ref. 12 on page 18) flashes.
See the paragraph on "DISPLAY MODE", page 20, for
details on the various information displayed by the
system.
If ignition or operating faults occur on any heating unit,
the display on the Master boiler starts flashing and the
red LED (5) comes on.
There are two possible types of errors:
- Type A errors, which can only be deactivated by pres-
sing RESET;
- Type E errors, which are deactivated when the causes
are no longer present (see ERROR MODE on page 24
and the "Fault codes" paragraph on page 56).

Checks During and After First Start-up

When ignition is complete, check that the POWER PLUS
boiler correctly:
- Starts and stops, closing the contacts on the zone ther-
mostats;
- Displays the DHW temperature (only if the storage hea-
ter is fitted) and central heating temperature, pressing
the "["button twice;
Check, if the storage heater is fitted, that parameter "6"
is set correctly:
2 = storage heater with probe
6 = storage heater with thermostat
and check that operation is correct, by opening a hot
water tap.
Check the complete shutdown of the boiler by moving
the main system switch to "off".
