Blue Solar MPPT 75/15 What do these Alarms mean: #111 and #22 Internal Tsensor miswired?

I have 4 x 75/15 Blue Solar MPPTs. All operating fine until three days ago when I started getting alarm messages on one of them. three days ago I got two messages: #2 Battery High Voltage (Li battery BMS did not register a high voltage event), and Alarm #22 Internal Tsenso miswired. ???

Then this morning an Alarm #111

Any ideas what #22 or #111 mean, and why I have gotten them??

First check: loose wires.
