Thermostat STC-3028 - Humidity and temperature regulator

The STC-3028 relay module with humidity and temperature sensors is a solution used in many projects where it is necessary to control humidity and air temperature simultaneously, i.e. in warehouses, production halls, dryers, greenhouses or museums. The controller has two LED displays: red for temperature and blue for humidity. Above the screens are LEDs, the light of which indicates the activated relay and, accordingly, the operation of the system. The thermostat can heat / cool, depending on the configuration, the meter can operate in drain / humidify modes.

Cooling function - we set the initial temperature (up arrow) higher than the final one. If the temperature read by the sensor is higher than or equal to the start temperature, the relay turns on and the cooling device operates. If the temperature is below or equal to the final temperature (down arrow), the relay switches off and the cooling device stops operating until the temperature reaches the initial temperature again.

Heating function - the start temperature (up arrow) must be lower than the final temperature - then the heater switches on. If the measured temperature reaches or exceeds the set temperature (down arrow), the heater switches off.
