Castle serenity timer function

[Sytamra]

the manual says nothing about how to use the timer button. Any help? I'd like to set it to turn the stove on in manual in 1 or 2 or 3 hours etc.
Thanks, Bryan

to the left of the display you push the top right button then use the arrow up down buttons to set start up or shut down in increments of an hour.
