STC-3028 AC 110-220V 10A Digital Temperature Controller Dual Display Thermostat Thermoregulator Heating Cooling Switch Digital Hygrometer with SHT20 Probe (AC 110-220V)

The instructions for this device are a bit confusing. I discovered that what they mean with the (Question Marks) in the setup portion is "?" means button 1 for UP for both Temp and RH..The "??" means button 2 on both Temp and RH. Took me forever to figure that part out. Was easy to program after I did. Was quite confusing indeed at first. Hope this helps you out.

It can be modified to whatever you need it for..work so well,I bought two more..

Muy buen producto , ha cumplido con mis expectativas , a pesar de ser muy pequeño resulta muy útil

The STC-3028 provided sloppy temperature control for my incubator. I have been using it for 2 months. The probe takes too long to react to changing temperature (equilibrate) and therefore shuts off at the setpoint but the actual temperature is well above. Humidity was well controlled but is not as critical of a factor in my setup. The temperature needed to stay at 37.5°C and would routinely go above 39°C after shutting off at the setpoint, which is unacceptable for biological systems. On the way down it would also fall below 35°C after turning back on at the setpoint of 37.5°C. I was very hopeful to have a good controller for temperature and humidity.In the end I swapped out the STC-3028 with one of my inkbird ITC-1000F and it was able to control the temperature in my incubator extremely well. So I decided to use the STC-3028 in my brooder, where exact temperature is not as important. It still is sloppy with temperature control but is manageable.The 1 meter (3 feet) cord is very short in my opinion, it would be nice to have a longer sensor cord.So if you do not need precise temperature control this device might be good for you and also be able to control humidity. I would not recommend this device if you need precise temperature control, especially of an incubator

Work great, on my incubator.

Used for humidity monitor. Has remote sensor to allow placing in cabinet.

Great concept if they would use higher quality parts. Will be Repairing myself. With. Name brand relays. If you buy one plan on rebuilding it

Compre dos de este artículos y los 2 vinieron con problema, uno desde conectarlo a la corriente me da error y el otro no apaga los bombillos estando muy bien conectado la instalación, es un fraude total
