I found the Anova users manual lacking of information of really how to control the display locally.
Here is my users manual.Amount of press times on the display are approximate times.
Changing between F & C
Hold the PLAY Button for about 6-8 seconds
To change again, press the PLAY in for about for 6-8 seconds to switch
Countdown Timer
Hold the PLAY button down for about 10 seconds
The timer icon should show up on the display (right side)
Press the timer display for about 5 seconds
Use the BLUE thumbwheel to set the time
Press the Timer to set time
Times up Alarm
If the timer is set,, at the the end of the Countdown Timer, there will be be 3 beeps
To Acknowledge the timer and quit the beeps, press the Blue display button (Left button)
Change Countdown Timer during Process
Hold the timer Icon down for about 3 seconds
Change Timer with the Blue thumbwheel
Press the timer icon to start or just wait for the timer to change
