Thanks!

I have currently lengthened them as far as I can without a major rewrite in that I have to deliver the whole sequence in << 0.5s to avoid busting a timing budget.  I used to have a combination of long and short flashes, but due to my miscommunicating that to Mark, his User Guide ended up with the simpler pattern that I then implemented.  We can have another think.

> 2. I've found myself wanting to know what status the unit was in by looking at it so a simple way to indicate what mode it's currently in would be great. For example, it could regularly flash the current mode with low intensity flashes (so as not to be disturbing for people). Of course, there may be better ways to do that in r2 with the newfangled controls.

Basically the more it flashes (when you’re not pressing buttons) the more heat is involved: off means in FROST mode, one flash means in WARM mode but not actually calling for heat, two means in WARM mode and calling for heat, and three means in BAKE mode.

Have a quick look at the User Guide and see if the diagram helps (and indeed matches what the unit is doing)!
