Temp controller wired to control ONLY compressor?
« on: November 14, 2017, 08:28:03 AM »
I'm interested in wiring a johnson/ronco type dual stage to control only the compressor in my freezer fermentation setup. I am, in no way, intimidated by the controller or heater setup; However, i don't know anythong about this "compressor delay" that people keep mentioning. I would like to run a hot to the controller directly from where the power comes into the freezer to the controller (for it's power) and then use a relay in the controller to connect/disconnect the hot line feeding the start capacitor and compressor. Can this be done safely? Will the condenser fan run endlessly? My objective here is to keep the freezer light functioning and easily be able to revert to factory function for resale value, should i ever decide to upgrade.

My freezer has a light as well. I didn’t care enough and simply set it up with an outlet and plug the freezer in. This is the best option for resale as “reverting” is nothing more than unplugging.
I have one of these stuck to the outside of the lid for peeking. They are frequently free with a coupon and the batteries last over a year.

I've been eyeing the itc-308s... i figured the extra $10 for the ranco would look better and seemed like a more reliable device, being designed for industrial/commercial  use. I guess a magnetic light would work. Pretty much just open the door to stick additional fermenters in. It doesn't take long to run blowoff into the water jug either.

$10 more plus wire and labor. The inkbirds get great reviews.

You can wire a socket to the Ranco if you want to stick with them. Going this route you can use a quality extension cord for the wire and split it in the middle. Plenty have done this before the inkbirds hit the scene.

I'll do some price shopping and compare my options. Thanks for the input.
