Re: Heat Fault Codes
Reliatel gas/electric rooftop units have a Heat Control Board as well as the Reliatel Control Board.
There are several version of the Heat Control Board, but two main varieties: 1) Spark ignition and 2) Hot Surface ignition.
The Heat Control Board has an LED for displaying status & fault information. It is very common for the heat faults to not be shown anywhere on the Trane diagrams.
