You do not need to reset everything you use it. **Q: What is that output connector? Is that some sort of US / Euro combo socket? Will it accept a USA standard NEMA-15 plug and hold it securely?** A: Yes. The socket on the controller is compatible with most plugs in the world. It's not a problem to hold US standard NEMA-15 plug securely. **Q: I purchased one of these and did not come with instructions. could someone tell me how to change c- f? i've tried everything. also other codes?** A: Press SET and UP at the same time and release buttons until CF appears on the screen. Then click set, then click UP or Down to choose C or F.Please note, once advanced setting is changed, all other settings will be reset to default. Please email us service@bayite.com for PDF manual. **Q: can the temperature probe be submerge in liquid? I want to use it for my slow cooker for sous vide cooking...** A: I use this device to measure the water temperature in my old fashioned ceramic crock slow cooker by filling the crock with water, placing the probe into the water and setting the temperature to on at low setting and off at high setting. I plug the slow cooker into the thermometer, and turn it on high to get to temperature(adding hot water from the sink to shorten this wait time) then low for cooking. It measures the temp of the water very accurately and I've been able to cook vacuum sealed meats in the water to the desired temperature. I have had 3 out of 3 successful cooking events using this method. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Inexpensive and featureful general purpose temperature controlled AC relay *by on Reviewed in the United States 2 September 2015* If you're even considering an AC relay temperature controller, don't even think twice. Just buy the WH1436. You will not regret the purchase. I promise.Review updated 2017/05 to account for model revision (older WH1436 vs newer WH1436A).+ Heating and cooling mode (i.e. power supplied if temperature is below or above a threshold)+ Waterproof thermocouple included! (this is pretty hard to find on the cheap)+ regulates down to 0.1 degree window (high/low bounds for on/off)+ F and C units+ TONS of advanced options: e.g. temperature alarms and compressor safety timeouts+ 1.1kW continuous power rating (up from the 880W in the 2015 model that I bought)+/- mechanical relay click sound when device toggles state (the A model likely now uses a silent solid state relay)- Not a PID controller (more details below on why this could matter)- Upside down power connector (the A revision now uses a NEMA 15-5, which is great, but the plug is still upside down)There are a lot of temperature controllers and sous-vide devices on the market. Some have more or less features than others. Some require other parts, like thermocouples. Heck, at one point I was even considering building my own with a microcontroller, relay, and temp probe (and hours of testing and frustration). The WH1436 is what I've been waiting for and I'm so glad I held out! It's a compact, simple little device and has all the pieces you need for under $30! That's way cheaper than even I could have built one for. Other devices sell for many times this price, up to hundreds of dollars, and aren't nearly as flexible. See the Anova, Dorkfoods, or Johnson for excellent overpriced examples.My target is sous-vide, but the WH1436 could also be used for cooling applications as well. Yes, the instruction manual is a bit overwhelming, but it is detailed and accurate. There are so many features if you really want to fiddle with things, but I found the defaults intelligently chosen and usable. One change I'd suggest is to lower the d parameter from 1.0 to 0.1 (the offset between the target temperature and the relay turning on). If you need help, search youtube for the videos from Bayite and you'll see detailed video instructions on how to use the device. If all else fails, just send the guy an email and he'll get back to you, or just post a question here, as others have done, and you'll see he replies quickly. Note, this paragraph was written based on the old software, the newer software seems to be even easier: set heating vs cooling mode, lower bound, and upper bound.The only legitimate complaint that you could make about this device is that it's not a PID controller. What this means is that it works only on instantaneous temperature measurements. A PID controller uses not just the current temperature, but also tracks the total power delivered (The I in PID), and the rate of change of the temperature (the D in PID), so that it can turn the heat/cooling on and off to keep the temperature exactly at the desired setpoint. This would manifest in behavior like the heat turning off prior to the desired setpoint because the PID controller knows that the temperature will continue to rise to hit the target. It's a more intelligent approach for control (and based on over hundred year old mathematical principles). The WH1436 doesn't have a PID controller, it's just instantaneous on/off based on the setpoint, so it's not as intelligent, but for slow moving temperature settings (like a big crock pot), it can still achieve excellent tight temperature control (my window sits with 1.5C). For the price, it's unbeatable. A PID controller would be a bit more expensive, as the logic is more complicated. What amazer me is that WILLHI did release a "PID" version last year that I bought (WHI1436PID). It wasn't actually a PID controller, but it did have some really neat parameters that would permit very tight temperature control (I got it down to 0.1-0.2C from my target). However, it seems like that model isn't sold anymore. I haven't purchased the updated model (WH1436A) yet, so I can't comment on how smart the newer software is, but if it permits bounding down to 0.1C/F, then that's about as tight as you can reliably get things with a consumer product.It is incredibly versatile because it just regulates an AC socket based on a temperature. I've used it for sous-vide with a crock pot, a rice cooker, and even a portable electric stove with a dutch oven on top. They all work perfectly and deliver fantastic results. At under $30, you can even buy a few of these and set them up to have multiple baths and temperatures going at the same time. Do beef in one, potatoes in another, and vegetables in a third. Things could always be cheaper, but this is a fair price point. These temperature controllers are not particularly expensive pieces of electronics, and I'm glad we finally have an inexpensive option that gets it all right. So long as what you're trying to power is under 1kW, buy this, you'll love it. Combined with an equally affordably priced vacuum sealer and manual slow cooker, you can sous-vide like a pro for under $100. ### ⭐⭐⭐⭐⭐ Good Temperature Sensor *by on Reviewed in Canada 5 March 2021* I am using this item to control the temperature in a confined space for brewing, spore growth and seed starting and it works very well indeed. It comes with good instructions and there is access to a video on u-tube if they are inadequate. I have been able to maintain a good solid temperature range and am very pleased with this product. ### ⭐⭐⭐⭐⭐ Set it and forget it! *by on Reviewed in Canada 30 December 2021* I purchased this unit to assist me in operating a home built smoker. I operate two 400 watt heating elements with it. I've found the directions to be concise although somewhat confusing but once the high and low temperatures are set and the temperature probe is in place the unit operates perfectly. ## Frequently Bought Together - WILLHI WH1436A 10A Temperature Controller 110V Digital Thermostat Switch Sous Vide Controller NTC 10K Sensor Improved Version - Amazon Basics Ceramic Space Heater, Mini Heater for Office Desk, Portable Tent Heater for Camping (Indoor Use), 500 W, With Tip-Over Protection, Lightweight (1.4 LBS), Black, 5.8"D x 3.4"W x 6"H - Commercial Chef Food Dehydrator, Dehydrator for Food and Jerky, 280W Meat Dehydrator Machine for Dehydrated Foods with 5 Drying Racks and Slide Out Tray, White --- ## 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.pt/products/54253818-wh1436a-110v-240v-digital-temperature-controller-thermostat-switch-ntc-10k](https://www.desertcart.pt/products/54253818-wh1436a-110v-240v-digital-temperature-controller-thermostat-switch-ntc-10k) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-11-14*
