Fault Code Retrieval
To retrieve fault codes, push and release ERROR button on control board. The LED will flash the
last five error codes, beginning with the most recent. If there are no fault codes in memory, the LED
will give two green flashes. To clear the fault code memory, push and hold the ERROR button for
at least five seconds. The LED will give three green flashes when the memory has been cleared.
Notice - Only a qualified service technician should use this feature.
Fault code retrieval functions will work only if there are no active thermostat signals.
