I purchased a chest freezer to convert into a kegerator (technically a "keezer") for homebrew - obviously freezers are meant to be used at temps below freezing, and I need to chill my homebrew to about 40*F, so a temp controller is required. I had never wired anything electronic before, but this was very simple and easy to accomplish. Overall, it was worth buying this unwired unit for cheaper, as I was able to wire it and install it myself for less $ than the pre-wired units from homebrew shops. If you have some steady hands, all the wires/tools required (you'll need pigtail wires, a spare 16 gauge extension cord cut in half, wire strippers, and some wire nuts) and a little bit of patience, it's worth it to purchase this unwired unit. The controller itself works great with my chest freezer - it's very simple to set up, and I'm able to achieve great temperature control for both chilling beer and maintaining specific fermentation temperatures. Highly recommended for fellow homebrewers looking to control their fermentation temps or trying to build a keezer. Review: There are several models in the A419 series. I needed a waterproof version, but due to desertcart's poor product description I initially purchased another model. I had to break the tape to determine that fact, so I was charged a 20% restocking fee. desertcart should do much better. ## Features - Setpoint Range -30 to 212°F (-34 to 100°C) - Differential Range 1 to 30F° (1 to 30C°) - Made for almost any refrigeration or HVAC control-voltage application - Easy-to-read LCD displays - A 30° (F° or C°) temp diff adjustment range allows precise (1F° or C°) temp diff settings ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0026NDC5O | | Brand | Johnson Controls | | Colour | gray | | Customer Reviews | 4.2 4.2 out of 5 stars (93) | | Display Type | LCD | | Manufacturer | Johnson Controls | | Manufacturer Part Number | A419ABC-1C | | Material | Plastic | | Model Number | A419ABC1C | | Operating Temperature | 100 Degrees Celsius | | UPC | 806224612353 | ## Product Details - **Brand:** Johnson Controls - **Colour:** gray - **Display type:** LCD - **Material:** Plastic - **Operating temperature:** 100 Degrees Celsius ## Images ![A419ABC-1C Electronic Temp Controller - Image 1](https://m.media-amazon.com/images/I/51731RXGtXL.jpg) ## Questions & Answers **Q: Does it include a probe?** A: Yes it does come with a probe **Q: Can this be used to hold water at a constant boil (212F) or higher?** A: The set point goes up to 212oF but not higher. So It should be able to hold temp in the 211-213 oF range. I don't know if that would be a constant boil or not but it would be close. **Q: can I put the whole sensor in the water tank to control the tempurature?** A: No **Q: Does this unit can use another type of probe? What type of probe uses?** A: What "type" are you referring? This control uses a resistance type sensor, electrical interference may affect sensor signals. when extending the connected wire a shielded type wire is recommended. and increasing the gauge is also recommended. The probe cam also be used for liquids, but should be in a well. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***D on 21 April 2011* This product was exactly what I needed.

Amazon should do much better. ### ⭐⭐⭐⭐⭐ Review *by S***N on 27 September 2012* Sous vide is a cooking technology that has come into popular use within the past decade. It might also be described as a fresh food preservation technique. My family really needed this, as it allows my teenage sons to cook for themselves with lower cost, less wastage, and better flavor and health prospects than they can get from fast foods. I combined the Johnson Controls A419 with an aquarium air stone to turn a simple 7 qt. Crockpot into a circulating water bath cooker that compares well with home sous vide controllers that are priced between $350 and $500. I combined the Johnson Controls A419 with a water heater element ($6 on EBay) and the air stone to turn a 28 qt. Coleman cooler into a high capacity sous vide cooker that can easily precook 100 entrees per day. The A419 relay output has been durable for me under heavy loads that are rumored online to do damage to the typical PID controller. The 1 degree F hysteresis of the A419 sounds like trouble to PID controller users who fool themselves into believing their water baths are accurate to 0.1 degrees, but it turns out that only the average temperature matters, as demonstrated by the excellent flavors of the prepared meats. ## Frequently Bought Together - Johnson Controls A419ABC-1C Electronic Temp Controller - AO Smith 9721 Multi-HP, 3.3-Inch Frame Diameter, 1/2-HP, 1550-RPM, 115,208-230-Volt, 1.1-Amp, Ball Bearing Motor - YZF18-25 Fan AC Motor 120V 18W 1.01A 60Hz Shaded Pole Condenser Motor Replace YZF10-20 YZF6-13 W0301905 for Refrigeration Equipment Radiator Evaporator Freezer, Small Ventilation Equipment 1550rpm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.eg/products/500734591-a419abc-1c-electronic-temp-controller](https://www.desertcart.com.eg/products/500734591-a419abc-1c-electronic-temp-controller) --- *Product available on Desertcart Egypt* *Store origin: EG* *Last updated: 2026-05-20*
