Error Code History

The thermostat remote is an invaluable tool in assisting with troubleshooting. In addition to setting and changing the temperature, the remote also has a secondary mode where it is able to monitor the heaters performance. 8 of these monitor channels holds the error code history for any incorrect operation of the heater. They can be referred to at any time by entering the maintenance monitor and navigating to monitor #91 for the most recent error code. Up to 8 error codes can be recorded. At no time will an error code show up more than two times back to back. Additionally, because the heater will only remember the last 8 error codes, if a new error comes up, then the error code on monitor #98 will “fall off” and all other error codes will bump up one position to make room for the most recent error code occurrence on monitor #91.
