DIAGNOSTICS

Accessing the furnace’s diagnostics menu provides ready ac-

cess to the last six faults detected by the furnace. Faults are

stored most recent to least recent. Any consecutively repeated

fault is stored a maximum of three times. Example: A clogged

return air filter causes the furnace limit to trip repeatedly. The

control will only store this fault the first three consecutive times

the fault occurs. Navigate to the diagnostics menu as described

above in Accessing and Navigating the Advanced Features

Menus.

NOTE: It is highly recommended that the fault history be cleared

when performing maintenance or servicing the furnace.
