    HVAC Fan Mode Light and Electric Water Heater On Light

    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.

    Thanks, Dan & Carol

    I've seen the same with the WH when the electric side is switched on...a brief flash of the DSI fault light. Either it's normal or we have the same problem.

    No idea what to suggest with the thermostat other than a loose connection.

    Dave and Monica and Don--thanks for the feedback.....appreciate it ! When I removed the thermostat cover the wires were blocking the clear plastic light emitting probes from brightly illuminating in the fan mode. I moved the wires abit, cover went on easily and fan light is bright like all the rest. Looks like water heater electric mode question is a non-issue and working as designed.
