STC-3028 Thermostat with Heat and Humidity Fully Explained and demonstrated
In this video STC-3028 Thermostat is fully explained. This thermost has two load controller so it can be used as temperature controller to control heater or cooler or it can be used at humidity controller to control humidifer or dehumidifier device. Both heat and humidity controller can be used at the same time. The thermostate uses SHT20 Humidity and Temperature sensor which can measure from -40°C to 150°C. Dasheet and list of components shown in this page.
The module is fully explained. All major components explained and datasheet for each component is shown. Then settings of the module is explained with diagram so you it is understood better. Wiring for AC which might be hard for some people shown.
Demonstration shown:
- Temperature: Heater control
- Temperature: Cooler control
- Humidity: Humidifier control
- Humidity: Dehumidifier control
