The controls are not as intuitive as I would like them, but once you do it a few times, you can figure it out easy. There are 4 buttons - clock, set, and up and down.
First set your time. Hit clock and play with it to set your current time. Make sure that AM and PM are correct - this is a common point where people have problems. Then toggle back to the home screen so that nothing is blinking.
Then, you can use the "set" button to toggle through your misting sessions.
The first time you hit "set", use the other buttons as up and down arrows to put it on "auto". "On" will mist without ever stopping (until the next programmed end, I think but am not sure) and "off" turns off everything, even all programmed sessions.
Hit set again - this will be your first misting session. Again, use the clock button to move between start time to duration to frequency, and the other two buttons as up and down to increase or decrease the value
- the first number is the time you want the mist to start - again check your AM/PM setting
- the second number is the how long you want the mist to run HOURS:MINUTES:SECONDS (NOT the end time - this is the number one place where people have problems because the old time used start and end times), so a 10 minute misting session would be 00:10:00
- above is a little strip that sets the days, toggle this until you hit "week" for every day
- use set to move to the next setting (there are 9 total) and repeat above
- when you are done, you will probably only use 3 or 4 sessions, max, keep hitting set until you toggle back to the home screen, and everything should be ready to work!
I would suggest setting a test session for one minute from the current time for 30 seconds so you can be sure you have set your times right.
