Displayed Component or System Operational State and Troubleshooting Tip
Alert Text
• System component control software is corrupted.
• Recycle power.
Failed Flash CRC
• If failure re-occurs, replace the system component control.
Check
Manual system power reset is required to recover from this alert code.
• The thermostat has found a problem with a system component's outdoor temperature sensor. In normal operation after system
component control recognizes sensors, the alarm will be sent if valid temperature reading is lost.
• Compare outdoor sensor resistance to temperature / resistance charts in unit installation instructions.
Outdoor
• Replace sensors pack if necessary.
Temperature
• At the beginning of (any) configuration, furnace, air-handler control or equipment interface module will detect the presence of the
Sensor Problem
sensor(s).
• If detected (reading in range), appropriate feature will be set as 'installed' and shown in the 'About' screen.
Automatically clears upon configuration, or sensing normal values.
• There is a discharge air temperature sensor issue.
• Compare discharge temperature sensor (DATS) resistance to temperature / resistance charts in system component installation
instruction.
• Replace discharge air sensor if necessary.
Discharge Air Temp
Sensor Problem • Confirm there is no short or open circuits in the iComfort thermostat connections to any of the other components in the
communication system.
• Issues with a DATS connected to smart hub not generate an alert code.

• Link Relay Problem. Relay Y1 Failure
• Possible Y1 relay failure.
Relay Y1 Stuck
• All system operations will stop.
Automatically clears five minutes after Y1 input sensed OFF.
• The O relay on the system component has failed. Either the pilot relay contacts did not close or the relay coil did not energize.
