When to Update Firmware
When Replacing a Failed Controller
Best practice is to update the firmware of the replacement controller prior to installation. Replacement controllers may have been stored for an extended period and could contain outdated firmware. Additionally, backups created with newer firmware versions are not compatible with controllers running older firmware and cannot be restored.
An example illustrating the necessity of firmware updates: Units utilizing A2L refrigerant require a minimum firmware version of V7.01.0016.
New Control Features and Enhancements
When a new firmware update is released, it often includes additional control features or improvements to existing control functionalities. These enhancements are designed to optimize the performance and operation of the equipment, potentially providing a better user experience for the customer.
An example of this is the ability to upgrade the license of a Symbio 700 from basic to advanced. This feature was not released until V6 of the Symbio 700.
