DISPLAY INDICATIONS WHEN AN ADR EVENT IS HAPPENING
After setting your desired values for use during an ADR event,
the scrolling display will give a little information when an event is
pending or active. For instance, when an ADR event has been sent
to your thermostat, you might see ADR STARTS at 4:15 to notify you
of a pending event. Once active, you might see ADR STOPS at 5:30.
When an event is active, you can press any of COOLER, WARMER or
MODE buttons, followed by the WARMER to opt out of the event.
