Best Refrigerator Hack

I converted my standard side by side refrigerator over to the electronic temp controller after several failed original style thermostats. This product was cheaper and I can see the exact temperature at any point. Wiring was pretty simple, just having to pull power off of the existing wiring already powering the light and defroster module. I cut an opening where the original thermostat sat and the cool temperatures inside the unit haven't seem to bother the operation. Simple settings don't have to be touched once set. I keep our lower limit at 34 and upper (turn on temperature) at 37. Nothing freezes now! No need for two relays like some of the others have for this project.

Great little controller- can't beat the price

I have purchased two of these controllers. I installed them about a week ago, and they are working well. One thing I like about this controller, it is very quick to respond, you can hold the temperature probe between your fingers and you can immediately see the temperature start to change.. One thing I don't like about the controller is when you're setting it for heating or cooling, you cannot confirm if it is set for heat or cool. However that's a small thing the controller is easy to set up and is easy to wire. The included wiring diagram is simple, and straight forward. I like that this controller can be set for either heat, or cool. I also like the fact that the output contacts from the controller isolated. I have a couple more projects I am working on, I am sure I will buy several more of these. I wish they made a differential temperature controller.

Used this to convert a deep freeze into a Super efficient refrigerator!

The controller works great! The user instructions are a little bit confusing but once you get them handled it is a snap. I used this to convert a 5.0 cubic foot chest freezer to a refrigerator. I was able to set a lower limit at which the unit turns off, and an upper limit at which it turns on. The freezer now chills to 33 degrees and shuts off for about 5 hours. When it reaches 42 degrees the unit turns on until it reaches 33 degrees. This takes about 30 minutes. ( I set the difference between the target temp and the upper limit at 12 degrees) In a 24 hour period the freezer compressor only runs a total of about 2 hours and fifteen minutes This controller can be used to set a target cold temperature [OFF] with an upper limit [ON] this is achieved by setting the temperature difference to the number of degrees above the target temp you want to allow before it turns on. This controller can also be used to control a heating unit. I chose this unit for it's ability to set upper and lower limits. I used an a grounded extension cord to provide juice to the unit and provide the switched outlet to plug my freezer into. I like the display that shows the current sensor temp and it's status. The long sensor cable is nice and didn't require me to modify the freezer at all. GREAT DEVICE. NICE PRICE.

Great temp controller. Such a good decision!

I used this to convert my chest freezer into a fermentation chamber that controls my fermenting beer to within a degree or two. Here is how I did it. I purchased a small ABS plastic "project box" and used an old extension chord that i cut into two 4' sections that are wired into this digital thermostat per package instructions. At the far end of each 4' chord is a male or female plug where one plugs into the freezer chord and the other plugs into the wall outlet. I mounted this set-up on the top of the freezer and the temperature probe dangles inside where i tape it to my fermentation bucket. Its easy to see and use this way. It works great and is in Fahrenheit!

Excellent temperatue control with clear instrucions

The Bayite temperature controller works great. There are many similar options, but I picked this one because it has well written instructions, and because it has the option to display in fahrenheit. The panel mounting retainers work nicely. Programming was easy. Electrical connections were straight forward. Most importantly, it controls temperature just the way I would expect it to. I have mine installed in a mini fridge that I am using for compressed air cooling/dehumidification.

This is a great devise. I used it in our greenhouse to turn on heat.

This is a great devise. I used it in our greenhouse to turn on heat in the fall and it worked very well. I later used it on a refrigerator that would freeze food and it has been great. One of the really good things is that it gives a temperature readout so you can see what temperature the space is at. The compressor time delay is very helpful to allow the compressor to not turn on to soon when there is a short cycle in the sensed temperature. Good devise and very precise. I am going to have to order another one for controlling heat in the pump house.

Every forced-air AC home should have one

First, this is one of the most valuable and informative purchases I have ever made. My initial intent was to use this to control a duct fan to boost cool air to an upper level room, which it does perfectly. Using the temperature probe in the heating/cooling duct, I now know at all times the temperature of air in the basement ductwork. I am now reassured that the temperature difference between air conditioning on and off is usually 20 degrees F, indicating my system is working well. I never knew this before and previously only had to guess. Should this number decrease over time, it would tell me that something is not functioning as well as before. Now I have a baseline. It also told me that the cool air pools in the basement ducts long after the compressor and main fan are shut off. No wonder my basement is so much cooler than the rest of the house and also what a waste of energy. Because of this device, I have purchased an intelligent thermostat that will run the furnace/AC fan for a period of time after the compressor stops to push the cool air from the basement to upper levels. Not only will this minimize the cold basement, but should more effectively cool the rest of the house and save a significant of amount of energy and money.

This thing is a Jewel!

I stumbled onto this product while searching for a dog house heater. The heaters were all costing about $100 to $150 and then I found this. I was thinking that this couldn't work because I would just have to buy it and a cheap little Lasko 200 watt heater for a total of under 40 bucks but I took a chance and ordered both. Worked Like A Charm! Besides the fact that my huge canine now has a heated dog house with a digital readout, I discovered that this Temperature Controller could be used for So Much More. It has So many settings that will handle almost any situation. It can electrically handle things that heat, things that cool, things that need to start (with capacitor 'start-up' options), etc. etc. You decide what temperature something will start or stop. It also has a waterproof sensor probe with well over 8 feet of wire that will let you locate it for almost any situation. It worked so perfectly that I'm going to get one to wire into my attic fan; one to monitor pond temperatures to activate pumps, etc. I never knew things like this existed. I just Hope To God that it holds up and continues to work as perfectly as it is doing now because I feel like a kid in a candy store.

Easy to install, works great.

Easy to install, worked perfectly right out of the box. Can be configured to any temp range, any tolerance plus or minus, and no internal relays so it is simply an on/off switch for the compressor which makes it very versatile in what it can be used on. Instructions weren't that great, but I've had far worse from other Chinese products. But they were usable. And thanks to the magic of the internet and YouTube I was able to figure out what was lacking in the instructions. I used this to fix my neighbor's flower shop cooler, the Italian-name branded replacement thermostat that looks a lot like it retails for $700. I get lots of free flowers now.

Simple to use and works well.

The instructions were straightforward and set up was simple. I used is to run a small heat element (two light bulbs!) in the garage located refrigerator. Here in Minnesota is stays cold enough that items in the refrigerator freeze if something isn't done. Manually turning the heat on and off works but is more than a little hit or miss. This hits the spot for taking the "miss" out of the equation. This model requires adding on the outlets to the screw terminals on the back, I believe another model comes with standard 110v plug receptacles already built in if that's what you need and you don't want to do it yourself.
