11.4 Malfunction codes
Incaseamalfunctioncodeappearsontheindoor
unituserinterfacedisplay,contactyourinstaller
andinformthemalfunctioncode,theunittype,and
serialnumber(youcanndthisinformationonthe
nameplateoftheunit).
Foryourreference,alistwithmalfunctioncodesis
provided.Yo u can,dependingonthelevelofthe
malfunctioncode,resetthecodebypushingthe
ON/OFFbutton.Ifnot,askyourinstallerforadvice.
