It's been a while since I updated this thread. Everything has been running smooth. I have 2 projects to post. The 1st is done, the 2nd I'm still working on.
This is a Ranco 2 stage temp controller. You can buy them prewired or DIY. I paid $72 for a brand new unwired unit, while a prewired unit directly from the manufacturer is $125. TFP sells a 1 stage controller
for $100. The unwired version comes with good instruction on how to wire it.
I took the top off and 1st started to connect the power wire.
Next are the wires for stage 1.
Then I shoved in the wires for stage 2. It started getting a little tight in there.
Everything all tied together.
And finally the finished unit. I can plug 2 heaters and 2 fans into it. I have it set so if the temp falls below 78 the heaters kick on and if the temp goes over 81 the fans kick on.
