Symbio 210 Firmware Restore and Recovery Methods
Rotary 999 - Return to Factory Defaults
In some cases, a corrupt database or similar problem may require returning the controller to factory
defaults.
999 returns the controller to factory defaults and clears database. Any custom programs will be
lost. The factory applied license file will not be cleared. The factory default program is located in
a special memory section on the controller that cannot be erased or overwritten. 999 accesses this
memory space when returning the controller to factory defaults. No USB stick or external file is
required for this process.
Follow this procedure to return controller to factory defaults:
1. Power down the Symbio 210.
2. Set the rotary switches to "999".
3. Power up the Symbio 210.
4. The green LED will be flashing code 45 which means within 30 seconds, you must set the rotary
5. Controller operation can be now be restored using Tracer TU or a backup file.
Rotary 998 - Restore from a USB Stick
Restore from a USB stick containing a firmware file. Restoring with 988 is intended to preserve the
configuration and settings of the controller. It is recommended to be in contact with technical
support before attempting this recovery.
In the event the Symbio 210 becomes unresponsive, you can attempt to restore is by following the
instructions below:
1. Power down the Symbio 210.
2. Set the rotary switches to 998.
3. Insert the USB stick containing only one full firmware (.scfx) file into the USB port on the
4. Power up the Symbio 210.
5. The green LED will flash several different codes as it progresses through the restore process.
6. Set the rotary switches to the correct address and cycle power.
7. Once the controller finishes booting after the power cycle it will start controlling equipment

result in system instability.
Heat TRIAC(s) can be checked by purchasing a 24 Vac LED and connecting to the TRIAC output.
