How to fix a version combination error on a Mitsubishi Electric Air Conditioner?
- TTracy CarneyJul 25, 2025
A version combination error on your Mitsubishi Electric Air Conditioner occurs because the apportioned electricity billing function of the AE-200 has been enabled, but the AE-50/EW-50 is a version that is not supported (version earlier than 7.23) by the apportioned electricity billing function. To resolve this, update the AE-50/EW-50 to Ver.7.23 or later. The equipment recovers from the error and then data collection resumes after a maximum of 30 minutes elapse. For how to update the software, refer to "VIII [1] AE-200/AE-50/EW-50 update procedure."
