Verifying an abnormal state in the past although the abnormal state no longer occurs
1.
Set bit 1 of DIP switch SW803 to ON.
2.
Jot down the states of LED800 to LED804. (Display mode 1)
3.
Press SW800 for at least 1 second. The LED status changes to display mode 2.
4.
Find an error whose display mode 1 equals the LED states jotted down and display mode 2 equals the current
flashing states of LED800 to LED804 from the following table to identify the error.
• An outside
air temperature (TO) sensor error
can be checked only while it occurs.
