InkbirdDual Stage ITC-1000 12V Digital Heating and Cooling Temperature Controller Thermostat for Fans, Aquarium Heaters

Useless product & overpriced 🤬🤬🤬

Just what I needed. I am using this to control the temperature of a peltier water cooling device I am building and it works flawlessly. It is fully programmable to heat or cool. I have it set to come on when the water reaches 68 degrees F and turn off at 65 degrees F. You simply set the on temp and the difference, which in my case is 3 degrees. It has a built in high temp alarm that engages and automatically shuts everything, except the alarm, down if for some reason it fails to to cool below the set high range....for instance a fan or water pump failure. It will protect the peltier from thermal runaway. I do recommend using an appropriate size fuse inline for the load. It comes with a wiring diagram affixed to the top as well as relatively clear instructions on how to program it. Another model I had of this same device had no instructions and I had to get on YouTube if learn how to program it. This one has clear instructions. Note that the orange clips slide off the back so that you can slide the controller into a panel and then slide the orange clips back in place to hold it securely in place. The instructions did not show this but it was easy enough to figure out.This model has the ability to select either F or C to display. The other one I had only had Celsius. It comes in 12v DC or 110V DC so make certain you order the proper one for your needs.The selection of Heat or Cool is carried out by which terminals you connect to. There are two terminals for heating or the other two terminals for cooling .No need to program the function. It automatically knows your selection by which terminals you are using. You need to make a wire shunt to run from the positive input to the cool or heat terminals depending on your needs.I can see where this would be a great method of providing temp control for incubators, brood boxes, or heat lamps for pets. Note that it has a 10 amp rating. If you need to carry a bigger load simply connect it to an appropriate sized relay. Know your load and stay safely under it or as I stated use an appropriate relay. I prefer using relays with built in diodes to prevent flyback voltage from knocking anything out.Get one......and have fun.

Used this to replace the failing peltzer cooler setup that came with my water cooler.Connected to a ample 12v power source this temperature controlled SWITCH works great at turning on and off any devices it's connected to.It is a switching device however, meaning you run the negative power leads to both this device and to whatever it's controlling, while the positive lead goes to this device, and then from this controller to the thing you want to control. In my case it's connected to a peltzer plate and a case fan for cooling.It's worked reliably every day, non stop, for several months now. It's easy to setup when you look over the included manual. Just be sure everything is buttoned up tight and correctly before turning it on.

If you need a super accurate thermo or quick response sensor look elsewhere, but for only $15 this unit is far superior to the one I replaced it with. The other unit had 2 readouts, one for set point and one for temp. and was easier to set, but it arrived DOA. As others state the only way to see the set point or to set it requires going through a programming loop which is a bit tedious, but if you are using it for a definite constant temp. with no need to change it then this is irrelevant. The sensor response time is slow in air and not surprisingly faster in liquid and the accuracy is not that great. Measuring the actual temp in air with an analytical instantaneous readout thermocouple based digital instrument placed next to the sensor bulb of this unit, even after adjusting the unit's calibration feature to match that of the analytical unit, showed a significant temp. variation over time even if allowing for the slower reading to stabilize. There is a fair bit of drift that can be as much as 8 degrees F in some cases. Even so for my purposes of cycling a compressor in a small mobile A/C system it is adequate. You can't expect this much functionality with great accuracy and super fast response time at this price. It works for me or at least it has for 2 weeks. If that changes an update will be posted.

Uno de los 2 controles que compre no tiene el cable con sensor
