Inkbird ITC-308S Dual Relay Digital Temperature Controller for Heating Cooling Device with 1.97in NTC Sensor Probe

My old refrigerator stopped regulating temperature so I was going to scrap it. I came along this product and now my fridge lives again! Accurate temperate control. Super easy setup. I was worried that there would be a loud relay clicking sound when it actuated, but nothing. Absolutely perfect product and I don’t even think I’m using it for its intended purpose. I won’t use the heat output so I can’t comment on it. Highly recommend!

Very easy to use. Plug and play. Works great.

It's great device but Inam giving negative reviews because: 1. The device is locked in heating whenever the SV temperature is lower then the ambient temperature. 2. They don't replies to email support. Item will be returned if not fixed

Very good product, I use this with a heat pad, and a home made insulated box for fermenting beer. This inkbird controller is much better than the previous controller I had and offers control for both heating and cooling. It has very accurate control perameters, and is easy to use and set, with a detachable heat probe. There was also a good deal on when I bought it and managed to get a discount with Amazon as well, so it turned out to be excellent value for money. I only use mine for heating on my set up as I don't currently have any additional space for making a dual fermenting chamber from a fridge.

This is a well designed and ready to use temperature controller. I am using it with my hybrid solar water heating system. My solar water heating system came with a single pump and a single temperature controller. I had to set the temperature of the controller as per the season or as per weather conditions hence making it semi automatic. I have installed one more motor in the system, which circulates the water from the insulated hot water tank through the glass tube collectors. For this motor, I have used this device to control the motor as a cooling device. The original temperature controller is set to 50°C, and the original motor fills the hot water insulated tank as soon as the water temperature reaches 50° integrate and shuts oof once the tank is full. I have set the temperature of this device to 70°C. So after the tank becomes full, the collector heating tube temperature starts to rise, and once it reaches 71°C. The second motor starts and again pumps the water from the insulated water tank, which is 50°C through the collector tubes and heats it up to 70°C. And the cycle continues. This way, I have made my semi automatic solar water heater into a fully automatic solar water heater for which this device is working very well since last one month. The temperature sensor is fairly accurate and the option to set the temperature difference up to 1°C is very useful. It is a plug and play device useful for people like me, who want to do experiments, but do not have Equipment or technical knowledge of assembling various spare parts. The probe of the temperature controller is expandable with good quality audio cable. I am using it with 15 m long audio extension cable. Due to which I am able to place the sensor on the solar water heating panel and the device in-house near the original control panel. I am highly satisfied with this device primarily and it is working well since a couple of months now. Let us see how long it works and will come up with a review again after long-term use.

Be careful you order the right model! I thought the 306 and 308 were almost the same except for the bluetooth extras. The 306 is only for heating applications (chicken coops) and won't work for cold water. I'm returning the 306 that I ordered on another platform (they didn't have the 308 which I would have ordered in the first place). The 308 does a good job with the thermostat and I'm getting used to it.

Bad product within 2 weeks while working in 40 degree centigrade stop working Then try to open it to fix it found the capacitor burn down
