Appliance Control Board

The appliance control board (shown opposite)

has a 2 digit display and 2 push buttons which

are used to check the status of the appliance,

check and set its identity and interrogate it for

the 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

below. 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 - see page 29 for details.

Appliance Type Selection

The BoilerMate is fitted with an identity (ID)

resistor which is read by the controller for

comparison with the appliance type (code)

set on the controller. The two must match for

the controller/appliance to function. Therefore

if either the appliance code setting or the ID

resistor is wrong, the appliance will shut down

safely and flag the error code until the fault

is rectified. The controller codes and the ID

resistor values for the BoilerMate are 01 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.

If the selected appliance code does not match

with the ID resistor fitted to the appliance, then,

an error ‘33’ will be displayed.
