For a boiler with a burner (type 2 - BRE) pressing the external button shall call up the same
function as pressing the button (hand symbol) of the ACD03/04 controller. It disables or
enables burner (BRE) operation.
For a boiler with a fan (type 3, 4, 5 - FAN or PRESS), pressing the external button shall call up
the same function as pressing the button (hand symbol) of the ACD03/04 controller, it only
switches the boiler fan on or off according to the boiler function logic.
ATTENTION - For combined boilers (DCxxSP(X), CxxSP, DCxxGSP - type 6, 7), the
BTN (BTNH) button function only works in boiler mode with manual stoking (as for 3, 5

of the button only invokes a secondary function on the controller display). The burner
must always be switched off on the ACD03 controller display.
