Honeywell Thermostat backlight TH8320u 1008
I have not seen this issue and the manual gives you the option of either off or dim to high upon key depress.
Manual:
0280 Backlight 0 Backlight on for approx. 8 seconds after keypress 1 Backlight always on low intensity, full bright after keypress (requires 24VAC connection).
I am sorry I can not offer any further info.
