message will appear on the display, and a tone will
sound.

letters “FLT” is an abbreviation for “fault”. The next set
of code letters indicate the type of fault and the zone
affected. Following is a list of possible codes that may
appear on the screen:
HTUF High Temperature Upper Front zone exceeded
HTUM High Temperature U pper Mid zone exceeded
HTUR High Temperature Upper Rear zone exceeded
HTLF High Tem perature Lower Front zone exceeded
