STC3028 Digital Temperature Humidity Controller Home Fridge Thermostat Hygrometer Control Switch AC 110 220V On the top of the STC 3028 you can check what type of voltage it is. There are three options to choose from : For alternating voltage (AC) “110-220VAC” and for direct voltage (DC) “12V” and “24V”. Now that you have checked which of the 3 options applies to your own device, you should wire the STC 3028 to the corresponding power source. The socket for the power supply corresponds to the sketch on the top of the STC. Functionality As you can see on the top of the STC 3008, “Sensor 1” and “Sensor 2” are next to the “Power supply”. Right of “Sensor 2” are both relays “Relay 1” for “Sensor 1” and “Relay 2” for “Sensor 2”. You can set a desired temperature for both “Sensor 1” and “Sensor 2”. Suppose we use “Sensor 1” for heating. For this purpose, a heating element is wired to “Relay 1”. In addition to the desired temperature, a minimum temperature is also set. As long as “Sensor 1” is colder than the desired temperature, the heating element is switched on via “Relay 1”. The heating element is only switched off when the temperature of “Sensor 1” has reached the desired temperature or is above it. If the temperature drops below the desired temperature again, the system waits until the initially set minimum temperature is reached. Then the heating element is reactivated and remai
