Merrychef High-Speed Oven Error Code E110: SRB Version Conflict
E110 means the firmware versions on the SRB relay board and the QTS touch screen board are incompatible. It can occur on board replacement and while loading firmware. The manual says to load current firmware from merrycheftechnical.com through autoup.ate, and replace both PMs and reload if it continues.
Medium: a version conflict that is usually cleared by reloading firmware.

What does Merrychef error code E110 mean?
The two control boards must run matching software. At start-up the oven compares the firmware versions, and if they cannot work together the display shows E110: SRB VERSION CONFLICT. The manual notes that this can happen when a board has been replaced, because a new board arrives with a different version, and during firmware loading, when one board has updated and the other has not yet. The first remedy is to load the current firmware from merrycheftechnical.com using the autoup.ate file, so both boards are brought to the same release. If the conflict continues, the manual says to replace both personality modules and reload the firmware. This is a software conflict and should not be confused with E083, which says the SRB hardware version itself is unsuitable.
Affected models and control systems

Possible causes
Likely causes — what usually sits behind error code E110 on this control. A technician confirms which one it is before any part is replaced.
- A replacement board arrived with a different firmware release

How a technician diagnoses error code E110
- Read the code and confirm E110 rather than E083.
- Check the firmware versions on both boards.
- Download current firmware from merrycheftechnical.com and load it with autoup.ate.
- If the conflict remains, replace both PMs and reload.
- Confirm start-up with no version message and run a test cook.
- Firmware loading needs the maker's files and an uninterrupted procedure.
- Replacing both PMs requires opening the cabinet and handling control boards.
How error code E110 differs from similar codes
