My JG wireless thermostats have been doing this funny light sequence for 3 days now:
https://drive.google.com/file/d/13sm_EGJdqf8t5KgTOKHehP8YsbTIHtZdyg/view?usp=sharing
They show the correct temperature for a few moments, then show 10 1d, then 9 1d then 8 1d then 7 1d and then revert to showing the temperature again.
Note the icicle symbol top right has also disappeared.
Can't see any mention of this 'feature' in the manual
Any ideas?
