How to Read the Error Code

The Integrated Furnace Control (IFC) uses Bluetooth communicating fault codes displayed via the contractor app. Codes use alphanumeric format with A (Active fault) or T (Transient fault) prefix followed by a 3-digit number and _F suffix. Active faults indicate a currently present condition; transient faults indicate an intermittent condition. Codes marked with * are two-stage only faults. All lockout conditions can be cleared by cycling power off and then back on. The furnace control will not initiate a heat cycle during any lockout condition.
