The ACB can be used to establish/check
the operating and set temperatures of the
appliance as well as identify faults on any
of the 3 sensors. This is done by operating
switches SW1 and SW2 as shown opposite and
reading the LED display.
Store T1, PHE T2, and DHW T3 indicate the
current value being read by the store, PHE
and DHW sensors respectively. The location
of the sensors is shown in Section 2.3
Commissioning.
T1 ON and T1 OFF show the store temperature
set points. T1 ON shows the temperature at
which the store will call for heat, i.e signal the
boiler to fire. T2 OFF shows the temperature at
which the store will be satisfied, i.e signal the
boiler to switch off.
These set point tempratures will vary
dependant on the position of the summer/
winter switch and whether the appliance is
sensing an ‘on’ or ‘off’ peak electrical supply.
The set point temperatures are shown in the
table opposite.
In addition to the main LED display the ACB has
four green LED’S which can be used to check
a supply is being provided when required to
the Boiler (LED 1), Boiler pump (LED 2) and
Heating pump (LED 3). LED 4 is not used on this
appliance. For further details refer to Section
2.3 Commissioning.
Note : If the ACB is replaced it will
automatically initialize itself when the
electricity supply is switched on.
The operation of the system controls/
operation should then be checked.
The same appliance control board is used
on a number of appliances and the jumpers
MUST be in the correct position for the
appliance to work satisfactorily, see Section
2.3 Commissioning for details.
When requesting a visit from the
manufacturer the installer must have the
completed ‘Benchmark’ commissioning/
service record sheet to hand to enable help
to be provided.
