Ok, this post is for all the people who want to upgrade their old Sportsman Incubators to the world of digital Electronic Temperature gauges - CHEAP!
I bought a Willhi Digital Temperature Gauge off of eBay (13.95), model number WH7016C. It came from China. My first one came with instructions, but somebody else needed it more than I did - so I sent them the one I had with the instruction sheet and ordered two more. The two I got DIDN'T come with instructions!
I thought I would have it handled because I did write down the wiring diagram I intended to use.
I had partially dismantled the Incubator to sand and paint it. I then put in one new cord for the power to the Temperature Controller (old light power cord), and used the wires that originally went to the thermo wafers to go to the controller relay. No extra relays - no power converters to 12V - no extras. I pulled the original two wires and the added power wire out through one of the holes for the Thermo wafer adjuster, the sensor comes in through the other hole.
I had all the wiring connected correctly but I couldn't get it to start the heater coil. I finally figured out that I hadn't setup the Controller correctly because the "work" light never came on - so I went hunting for the instructions. I found some on the internet - and after re-translating it into American I was able to change the controller - and now its WORKING! WOO HOO!
If anybody else is using this controller to replace the thermo wafers and needs the directions, let me know.
Now I have to get the missing trays for the turner, the hatching tray, the egg holders and the sock for the hygrometer. I will be leaving the old thermometers in there, but will probably be getting an electronic hygrometer at some point in the future - one that can record highs and lows for me.
I LOVE it when a plan comes together!
