Our 303RLS HVAC Fan mode green LED light is very very dim as compared with the bright green LED glow indicators when on Cool or Furnace modes.......is this normal or should the Fan mode be bright as well ?

Also,when our water heater is on electric mode, their is a brief very faint red light when first turned on but nothing after that.......is that normal ? When on gas mode, the red indicator glows brightly as one would assume.
