  • p2: Conventional 2-stage compressor heating when 2-stage compessor is set u
  • 50: % Off high heat

Fault Code Reset

To clear the fault code memory, push and hold the “LAST ERROR” button for more than 5 seconds and less than 10 seconds (the LED will indicate this period by RAPID GREEN FLASH for 5 seconds to 10 seconds). The LED will flash three green flashes when the memory has been cleared.

The ignition control is equipped with a momentary push button switch that can be used to display on the diagnostic LED the last five faults detected by the control. The control must be in Standby Mode (no thermostat inputs) to use the feature.

Depress the push button switch for approximately 2 seconds. Release the switch when the LED is turned off. The diagnostic LED will then display the flash codes associated with the last five detected faults. The order of display is the most recent fault to the least recent fault.
