The PID temperature controllers typically run less than $30 each. Ones that are not PID, which is fine for a brooder, normally are in the $10 to $20 range. The way to override a wafer is by screwing it all the way out so that it is allowing power constantly or it can be used as a safety back up by setting the off temperature at a temperature a few degrees higher than the temperature controller is set at.I had to google what a PID temperature controller was... looks like a grand idea. I only paid $279 per level for the brooder, it looks like the controller would run that much or more? And I do not know how to over-ride the wafer thermostat. I have some very basic capabilities but this looks like it is over my head. Sigh would have been nice.
I do have to say that being able to adjust them with a knob is much nicer than moving the heat bulb around trying to get it "just right"
The hope is that once I get my program "dialed in" it will be easier
