You are pretty much bang on !!!
Frost symbol means it is in f p mode and radiator will heat up when temperature drops very low
1-4 are indicator settings for the trv or thermostatic radiator valve 1 being coolest and 4 being warmest
When you turn the trv it will engage it and rad will heat up
Triangle when lined up with a dot or line on the valve means the flow to the radiator is fully open
