H = HIGH LIMIT - If "H" is present, the high limit is good. If "-" shows then the high limit
is tripped out (overheated) or disconnected.
D = DRAIN SWITCH - If "D" is present, the drain handle (when applicable) is closed. If
"-" shows then the drain is open or the switch is faulty.
F = FAN (PRESSURE SWITCH) - If "F" is present, the pressure witch is good. If "-"
shows in the display, the switch is faulty.
