Welcome Madman,
In short, you need to connect the service tool from Triumph. If you can't get it to a dealer, you can get a Tuneboy (Google it). This is a software interface system you install on your PC/Laptop to check fault codes and download custom tunes.
If the light stays on for more than three heat/cool cycles, you'll need to get it checked out somehow. If it goes out, then you could leave it until you get to a dealer.
I hear Bulgaria is lovely this time of year!
