Temperature Controller, KKmoon Digital Temperature Controller Thermocouple with Sensor (-58~194°F) 10A 110V

This little device is a fantastic alternative to products costing five times as much. It works just as well, and with a suitable enclosure, works perfectly as a temperature controller for fish, hermit crabs, industrial control, and so on.Hookup of the wiring is straightforward, and can be done without referring to the instructions, although a simple circuit diagram is included that makes it easy.I do wish the probe wire was a bit longer, but it can easily be extended with any non-shielded two-conductor wire (speaker wire even works).The main problem with the device is the operating instructions. They are absolutely horrendous - they are in "Chinese English" - i.e. translated by some computer from Chinese into English, and done so extremely poorly. Literally, they are absolute nonsense, and for the most part indecipherable. So you are left to your own devices trying to figure out how to work the thing.Once I had spent a bunch of time figuring the it out, I decided to write my own instructions so that I could refer back to them when I needed to. I'll share what I wrote here, so that you don't have to go through the same pain I did in figuring the thing out:Thermostat Operating InstructionsThe thermostat has a display that shows the current temperature detected by the probe. It also has two small LEDs to the left of the temperature display that light up when the relay is engaged. One LED lights up when the relay is engaged and the thermostat is in heating mode, the other LED lights up when the relay is engaged and the thermostat is in cooling mode.There are four buttons to the right of the display: Set, Rst, UP and DOWN (indicated by small arrows).Normal operation:Press the Set button. The display will begin flashing the current temperature the thermostat is set to. Press UP or DOWN to adjust the set temperature. Hold UP or DOWN for two seconds to rapidly change the temperature. When finished, press Set again to save the new temperature.Press and hold the DOWN button for three seconds to lock the display. The display will flash "OFF" for several seconds, and then return to normal temperature readout; however the user will not be able to adjust the preset temperature or parameters. To unlock the display, press and hold the "DOWN" button for three seconds again. The display will flash "ON" for several seconds, then return to normal temperature readout, and the display will be unlocked.Configuration:To enter setup mode, press and hold the Set button for three seconds. The display will show "HC". You are now in the Parameter Select mode. Press the UP and DOWN buttons to cycle through the various parameters available to set. To modify a parameter, press the Set button to get to the Parameter Adjust mode. Once in this mode, adjust the value of the parameter with the UP and DOWN buttons, then press the Set button to save the new parameter. This will return you to the Parameter Select mode. When finished changing parameters, press Rst to return to normal temperature mode, or just wait for a short while and it will return automatically.Below is a list of the available parameters:HC: Select between heat "H" or cool "C" mode. In heat mode, the relay is turned on when the temperature drops below the set temperature. In cool mode, the relay is turned on when the temperature rises above the set temperature.CA: Calibration (degrees). Enter a positive or negative number that will adjust the temperature shown on the screen, used to adjust for temperature read error. If the temperature of the area being measured is 75 degrees, but the display is showing 76.5 degrees, you would adjust this parameter to "-1.5" - this will subtract 1.5 degrees from the temperature being shown on the screen, and used to determine when the engage the relay.PU: Delay (minutes). In air conditioning applications, compressors can be damaged if they are cycled on and off too quickly. This introduces a delay that is enforced whenever the relay is cycled, to avoid this type of damage. It can safely be set to zero in heating or non-compressor-driven air conditioning applications.HA: Upper limit (degrees). This value is the maximum value the user will be able to set the thermostat. If you don't want someone to be able to set the temperature above 78 degrees, set this value to 78.LA: Lower limit (degrees). This value is the minimum value the user will be able to set the thermostat. If you don't want someone to be able to set the temperature below 58 degrees, set this value to 58.CP: Slew (degrees). This value prevents the relay from cycling on and off too quickly as temperature changes. For instance if the slew value is set to 2 and the thermostat is set 75 in heat mode, the thermostat will actually turn the relay on when the temperature drops to 73, and keep it on until the temperature rises to 77, at which time it will turn it off.All parameters can be reset to factory defaults by pressing and holding the Rst button for three seconds.

I purchased this unit to build a simple sous vide cooker. It has worked flawlessly so far and I can't be happier. With my 2.5 quart Crock Pot, I get about a +/- 2 degree swing around the setpoint (test with a setpoint of 134degF).Terminal description:There are 6 terminals on the back of the unit and are number 1-6 from left to right. The left most (1 and 2) are the switch terminals. The middle (3 and 4) are the power. The right (5 and 6) are for the thermocouple. Although the terminals are identified on the unit with regular old Arabic numerals the text there is foreign, most likely Chinese, characters.Assemply ofTo hook up the unit I split an extension cord and put the temperature controller in the middle, which the following instructions detail: I purchased a http://amzn.com/B0002J1KRQ and cut it 1/3 of the way down from the female end. The only other parts needed are an extra piece of wire the same gauge as the wire in the extension cord 1.5" long and one wire nut. After cutting the extension cord and I then cut back 1.5 of an inch of the main insulation (on both pieces of the extension cable) exposing the 3 insulated wires per piece of cable. Next I stripped all of the insulators back 1/4 of an inch to exposes the wires (3 per piece of cable and twice on each side of the extra wire). The neutral, white, wires I joined together and mounted into terminal block 4. The male cable's (the one that plugs into the wall) black wire and one end of the extra wire were mounted into terminal block 3. The other end of the extra wire was mounted into terminal block 2. The black wire from the female side of the extension (part the crock or other device plugs into) was mounted into terminal block 1. The green (ground) wires from each side of the cable were connected with a wire nut. The two ends of the thermocouple were mounted into terminals blocks 5 and 6. I looped the ground up over the screw extrusion where the back plate mounts and screwed down the back plate (this holds the ground line up and pins the extension cable up into the back and force the ends of the now pieced back together extension cord out of each end of the temperature controller. (see Ravi's customer image ... it is very close to my assembly).Note: If you don't have an extra piece of wire just cut 1.5" off of the long side of the extension cable after cutting the cable in half and take the black insulated wire as your extra piece of wire.See customer images for a picture of my setup.Manual: Most the manual is in very poor broken English, but I found it easily decipherable. That said besides the table, you really don't need it.Codes (hold set for 3+ seconds to access)HC - heat/cool - H/C (heat or cool); heat mode turns on switch when temp is too cold (setting - hysteresis). cool mode turn on switch when temp is too hot (setting + hysteresis).CP - slew or hysteresis - 1-30 degrees F; see above for usageLA - lowest operating temperature - -58 degrees F; when exceeded the device will switch off the load and blink LLL.HA - highest operating temperature - 194 degrees F; when exceeded the device will switch off the load and blink HHH.PU - delayed start - 0-10 minutes; When heat/cool setpoint (- [for heating]/+ [for cooling] the hysteresis) is reached the delay will start counting down and then switch on the connected load. The intent here is to give a minimum off time to a device, e.g. a compressor, which if not given proper time to internally cool from switch on heat inertia will be damaged.CA - temperature correction - -10-10 degrees FSet:Hold for 3+ second to access setting menu. Press set to accept and exit settings menu after configuring a parameter.Rst: In set menu less than 3 second press exits.(3+ seconds when in set menu to reset to factory defaults or 6+ second anywhere else to reset to factory defaults)UpArrow: Increases settings. When not in setting menu this sets the heat/cool set point. Hold for 2+ seconds to auto advance.DownArrow: Decreases settings. When not in setting menu this sets the heat/cool set point. Hold for 2+ seconds to auto advance. (From main display of temperature hold for 6+ seconds to lock parameters, including temperature set point, from being changed; hold another 6+ second to release from lock mode).The light next to Heat or Cool turns on when the load is on.

C est un peu compliquer de comprendre ou brancher les fils maisil y a de bons videos explicatif sur youtube .wow..une fois faite c est tres precis. On est tres satisfait. Nous c est pour faire fonctionner un fan de poele a bois quand le temperature est assez chaude dans cette piece il envoie la chaleur dans les autres pieces..merveille!! Petit mais gros chiffres..parfait !

Works good ONCE you figure it out. Oh my goodness that was interesting. Any of the YouTube videos are for different versions and not for this one and this one has different buttons so that made things interesting. With lots of fiddling around, I finally figured it out.It does work though. I used it for a home made incubator. It was reliable.

Does what it should, BUT IF YOU ARE BUILDING A KEG FRIDGE: be weary of doing it this way. I would highly recommend instead buying a simple plug-in style thermostat that has its own temp probe. The overall cost of the materials for a keggerator conversion thermostat puts this option as more expensive.I also wished this one was in Celsius, but it works!

Perfect for the use we had in mind. Works without any issues. A bit long to receive the item, but we already knew since this is the second we've ordered.

Absolute Garbage. Bought it for a project. Just got around to using it. The display on it does not work.
