A001_F: Model Data Configuration Error
Status
This is a critical alarm, the furnace will not operate in any mode.
Description
This code is displayed anytime there is no model data at the furnace. The model data is electronically stored data that is used to define (among other things) blower operation. Without model data, the furnace cannot function.

Cause
Faulty control board - possibly incorrect Bluetooth/EcoNet set up
