Lightbulb Trane XL80 red light flashing, when summer AC mode

Hello,

I noticed my Trane XL80 red indicator light is flashing, approximately 1 blink per second.
It is summer now, and heater does not work, only AC works (they are integrated, so Trane is pumping that air).
I did not notice it flashing before - here I made a video to demonstrate it:

Plz, what is this?
Sorry if silly question, I am not knowledgable in this area.

regards,
Anar

If you take off the bottom panel there should be something that tells what the blink codes are.

In general, for a Trane a slow single flash is normal with no heat call. It is just something to show that it is alive, nothing to worry about.

Welcome to the forums.

Flashing slow is normal. No call for heat
Flashing fast is a call for heat.

oh, so it should flash even in summer? I think I did not see this before, but probably I just did not notice.
thank you for explaining
