MAINS SWITCH
The mains switch [1] is used to switch the boiler on and
off.
"RESET" BUTTON
If a fault has occurred you may have to restart the boiler
by pressing the "Reset" button [2]. This is only required
in the event of a "locking" fault. "Blocking" faults are
reset automatically as soon as their cause has been
corrected. The display shows [\/r/e| during the reset
operation.
If the boiler stops due to a fault again after
resetting the fault, the fault can be
remedied using the Service instructions.
Contact Worcester if necessary. See the
back of this document for contact details.
"CHIMNEY SWEEP" BUTTON
The "Chimney sweep" button ([3] is used to put the
boiler into flue gas test, service or manual operation
mode.
The flue gas test enables the boiler to be run in full-load
operation manually for a short period. See table 10,
"Flue gas test", page 42.
The service mode enables the boiler to be run in part-
load operation manually for a short period.
Measurements and settings are carried out on the boiler
during service mode. See table 11, "Service mode",
page 43.
Manual operation mode enables the boiler to be
operated manually for a long period. The boiler is
switched to manual mode when the control system has
not been installed yet or is out of order. See table 12,
"Manual operation", page 44.
A maximum heating water temperature in accordance
with the setting of the "Maximum heating water
temperature" dial [8] on the BC 10 basic controller
applies during chimney sweep, service and manual
operation.
WARNING:
Damage to the installation with underfloor
heating: by the floor being overheated.
B Limit the maximum CH flow temperature
using the "Maximum CH flow
temperature" dial [8] to the maximum
flow temperature of the floor heating
circuit (usually maximum 40 °C).
