Now we have set the Time and we have removed any offsets to the thermometers.
So let's check our work so far. Press the reset button on the Arduino or cycle the power off and then back on.

This is your normal RUN screen.
The --.--% will be replaced with ABV% readings when the still gets hot enough.
And, for now, FS is displayed in the corner in anticipation of Fore Shots.
The #1 sensor displays on the top row and shows the Parrot's ABV being produced.
The #2 sensor displays the boiler vapor temperature and its %AVB.
Use the ↓ button to navigate to where we left off - the Blr Offs (Boiler Offset) screen.
One more ↓ and we enter the wonderful world of alarms.

A very tall, packed column will hold that high %ABV for a long time but production slows as the boiler's ABV gets depleted.
So the first thing out of the still, the very highest %ABV is the nasty foreshots - also known as FORES and displayed on the screen as FS.
And this is the first of our Alarm Settings.
I'll assume for a moment that I'm wanting to set up the still, and the alarms, for a neutral spirit.
The 1 alarm will be set very high, about 96%. This is the FORES.
Alarm 2 I'll set to 95% as that will be most of the run.
Alarm 3 at 94% will alert me that I'm very probably into the tails.
Alarm 4 I'll set to about 40% to collect some for recycling. Anything under 40% with a tall, packed column is hardly worth the effort to collect.
The last setting for this screen appears under the letters BLR. For now, until I learn better, I'll set that to about 80 to 85C.
I'll get an alarm that should remind me to turn the condenser water on.
The main screen will display the approximate time left to heat the boiler to the set point.
