Liner Protection Mode
¾ Liner Protection mode is controlled by two timers.
¾ Timer #1 monitors door-open time. A 3-minute door-open count begins when
the door is opened.
¾ If 3 minutes elapse before the door is closed, the liner protection mode will
become active.
¾ Once the door is closed, timer #1 resets and liner protection mode goes into
standby.
¾ In standby, normal fan operation resumes and timer #2 begins a 3-minute
door-closed count.
¾ If 3 minutes elapse without a door opening, liner protection mode will reset.
¾ If a door is opened within the timer #2 door-closed count, the remaining time
in the door-closed count will be deducted from the timer #1 door-open count.
