I have a neighbor with a Honeywell model 6442 (installed 2014) with, what appears to be, an Evolution controller.  He is experiencing the notorious error 2400 fuse alarm.  Of course, this disables the genset operation until reset.  My question is this, is the latest Generac firmware v 1.20 ok to apply to the Honeywell brand?  I don't want to "brick" the controller.

Yes, it's an Evolution control in sheep's clothing.
