STC-1000 Temperature Controller Thermostat Incubator Electronic Digital Display Temperature Relay NTC Sensor (Upgraded -50° ~ 99°C) Multipurpose Controller With Sensor Probe

I was fed up with my 10 year old samsung refrigerator which was over cooling and farming ice or near ice formation on veggies and leading them to rot. Two visits were made by Samsung technicians and replaced thermo sensor unit and main controller board but the issue was same and not resolved. After spending good amount to pay Samsung i decided to try this little unit to control the refrigerator compressor. I have set the temperature at 15 deg and now I don't have issues with refrigerator. Although this is not a perfect way to fix the refrigeratory problem of ice formation is resolved. Since the compressor voltage was been controlled by board and not direct 220v I removed the compressor heat sensor cables jand connected to this temperature controller unit. The unit disconnects the compressor if the temperature in refrigerator reaches 15 degree and connect it when temperature goes beyond 15. Earlier i used to switch off the refrigerator during night and switch on during day as a temporary fix. Now I am relieved. One challenge i am facing using this method is that the compressor takes additional 30mins to switch on...i am not sure why it goes to sleep mode everytime it is turned off and on... Any expert please comment on solution to disable compressor going to sleep mode

I fitted for a heating job. All is well...information booklet can be better if includes clarity that load has to be connected in series...

The media could not be loaded. Fairly easy to set up, though wiring instructions could have been more clear.It worked great for keeping my chocolates at the temperature I want them, but after about a month, it failed -- the numbers just flicker randomly and no power is delivered.

Temprature is not working properly, I requested for the replacement but same is not yet done. I lost my Chicks and money both

Its just okay

The media could not be loaded. Good morning. My National Window AC (old model) which is over cooling due to thermostat failure (mechanical type) I tried this Multipurpose controller and got success.First I connected the device input with 220v Ac (same terminal of Stabilizer output) & checked, it shows 30.0°C ( Room temperature) and cool status. Then I removed the thermostat wires from the ac unit and connect to the cooling point in the device with some extra wires. Kept the sensor close to AC coil. As per instruction I set parameters 24.0°C -28.0°C. Now it working nicely. (See the photos and Videos attached) After 4 minutes when temperature reaches 23.6°C (24°C) the ac compressor gets off. The fan is working as usual in AC unit. Gradually Room Temperature increases. When nearing 27~28°C the device switch on the cooling relay and the compressor starts to work. I used the device a whole night without any issues. I am very Happy now.Happy to come back, after two years use ( bought on 15 August 2022) today 17.08.2024 it is still working well without any issue.

The product worked excellent for four months and certainly died one day. The quality of the product must be of very poor.

Better then other, value for money
