I made sure I ordered one with the Dickey... because my average humidity here is 16% or lower especially during the summer with the dry air and A/C on all the time, and I have to add water every 3 days or so to my Hovabators. So I know I will love not having to open the Dickey. Not sure I need the auto humidity system for the hatcher, the pan (or pans) I'm going to use shouldn't run out of water for a 3 or 4 day lock-down... I hope not anyway, lol.
Thanks for the tip about distilled water for the float valve. That system is a pain in the hind end to put in/take out, so it wouldn't be that easy to work on it in a hurry if the float fails. My well water is bad about deposits, so yah... time to stock up on a few gallons of distilled water.
Sounds like the herpstat temp controller is the way to go... how much did that set ya back?
You may be right about not needing it for a hatcher but if you are constantly adding eggs to the hatcher it may be beneficial. Wow it must be nice to have humidity that high. During the winter my house humidity can and does get below 10%. In the summer it is a different story. Because of the naturally low humidity, I use a swamp cooler and no air conditioner bringing the humidity up into the 40% range.
When you consider that an electronic thermostat runs in the mid $80.00 range, the herpstat is not that bad price wise. I got the herpstat 1 basic because it came with a three prong plug and then found when I opened things up that even though my 1202 had a three prong plug on it, it was not a grounded system and it would have worked just as well to go with the herpstat intro or the intro +.
I did have to open the cabinet by removing the top to get at the wiring to divorce the turner and fan from the thermostat and heating element. I put them on a switched cord so that I can just turn the switch on instead of plugging/unplugging the cord to control the on and off. I also removed the old electronic thermostat but did leave in the wafer system to control over heating. It is just purring along so well that I have finally quit checking the temperature every time I go past (mine is in the dining room).

I did get an indoor/outdoor weather station and put the remote sensor inside the incubator to give a double check on the temperature and an easy way to see what the humidity is inside the incubator. It is another item that turned out to be well worth it to me.
Good luck and keep hatching those keets. By the way, I put my first batch of turkey eggs in the incubator last Saturday but still haven't found any guinea eggs from my lone lavender hen.
