Appliance Control Board

The appliance control board (shown above) has a 2 digit display and 2 push buttons.
Although this can be used to check the status of the appliance, we would suggest that
this is done on the control panel/display window on the front of the appliance, unless
this is faulty. However the controls should be used to check and set the appliance
identity and to interrogate it for any current faults and the fault history.
The 2 digit display is controlled by 2 buttons S1 and S2 The flow chart of display modes
is shown above. Generally, each press of button S2 cycles the display from top to
bottom and each press of button S1 cycles the display functions from left to right.
The button S2 is also used to reset the appliance i.e. clear the lockout errors and reset
the appliance. (Note: Appliance resetting can also be carried out using the push button
on the front panel)

Display in Normal (Standby) Mode

In the standard/normal mode the 2 digit display indicates the status of the appliance
inputs and outputs by switching on the appropriate segments of the display. Details of
the function/operation of the display are described in the Installation section of these
instructions.

down safely and flag the error code until the
S1 S1 fault is rectified. The controller codes and the ID S1
resistor values for the BoilerMate are A01 and
1K5 respectively. The procedure for checking
and setting the appliance code on the controller
is described below.
• The appliance selection menu (A0 ... A9) on
the controller is hidden. It is only possible to
get to the appliance selection using the reset
button (Left hand, S2) on the main board.
• When going from the show ' locking error' to
show 'blocking error' menu (see opposite), do
not release the button but hold it for 10 seconds.
The display will change from 'c' to 'A' . At this stage
the push button (S2) can be released.
• The appliance type can now be selected by
using right hand push button, S1, e.g. for this
appliance A01.
Press the reset button, S2, to accept the setting.
