    Yeah, I know. They are a pain in the butt. But they pay the bills to keep my server running. Just a fact of life, I am afraid.

    Want to get rid of them? Simple. Just become a Contributor level member or above and they will be gone. -> Please click HERE."

    Is that too much for me to ask of you to keep this site running? Well, sorry about that. I too wish I could get everything for free. But alas.....

    =====================


    Google Adsense ad revenue for December, 2025 was just $30 over the cost of the lease for the server running this site. So, in effect, the money providing the incentive for me to continue running this site is coming SOLELY from the paid memberships and sponsorships here. Which honestly ain't much....

If you want to wire up a couple like in the link, I can set up some instructions for you. It might take me a couple of days due to work schedule, but I can get them made for you. It's not difficult to wire them.

Hey Dennis,
Did you get a chance to get these instructions made up? I need a few of these and want to wire them up doubled. I was also wondering if you do any kind of price break if several of these are ordered. You can e-mail me if you want. -Chris
 
I've had Ranco units display the E2 error after electric service fluctuations and interruptions. I my cases E2 is displayed and power output from the unit ceases until the unit is reprogrammed. I've discovered that those units that exhibit this tend to be the same units to repeat it. Due to the repetition I replace those units and no longer reprogram them.


Do the Johnson units have a differential adjustable to one degree f like the Rancos?

I use the Johnson control a419 and it does have the 1degree differntial. I am replacing my older controls this year with spyder robotics. I plan to run my older johnson controls in series on my colubrid racks. I think you will be happy with the Johnson Controls

Yes they do, I have a Johnson I got from Dennis last year, it is a dang good one, I am well pleased with the way it works. I hatched off 324 tegu babies with mine this past season with it without any glitches.
 
I do like the LED feature of the Johnson controllers. As everyone knows, you've got to get right up close to the Ranco display to see the relay status.

In tough environments, however, I do prefer the Ranco unit and with an encased sensor.
 
I am using mine to incubate 10 dozen chicken eggs, for the tegus this season. It is just perfect at 97*F and holding steady.
 
havent had my ranco about a month and my powerstrip kept kicking out, so i unwired it and just wired my heat straight in
 
I have had two Rancos quit working for me, one this year and one last year. The Johnson is still working fine though. I bought all three about 3-4 years ago.
