With the unit plugged in:
1. Turn all of the switches off.
2. Turn on in this order 2, 5, 6, 7 and 8.
3. Wait for the light to quit blinking.
4. Turn off 2 and then on again.
5. Wait for the light to quit blinking.
6. Turn off all of the switches and turn 4 back on.
Put the lid back on the bator and let it stabilize for an hour and take a temperature reading. This should have dropped it about 2 degrees or less. If you need to adjust more, here are the approximate switch values:
1 = .5 degrees down
2 = ~ 2 degrees down
3 = ~ 3.5 degrees down
4 = 5 degrees down
5 = 5 degrees up
6 = ~ 3.5 degrees up
7 = ~ 2 degrees up
8 = .5 degrees up
Just to clarify, to turn down select switch 1-4 depending on the increment you want to lower, turn it on and then turn on 5, 6, 7, 8 in that order. Toggle the switch you selected once (off then on) for every increment drop. For example you would toggle switch 1 twice to drop 1 degree. To turn it up select switch 5-8, turn it on and then turn on 4, 3, 2, 1 in that order. Toggle the switch you selected to raise the temp.
I hope that makes sense.
