W3230 Digital Temperature Controller — LED Thermostat, Heating/Cooling, DC 12/24V or AC 110/220V, NTC Sensor

W3230 Digital Temperature Controller — LED Thermostat with Heating & Cooling Switch

The W3230 is a compact digital thermostat module with a bright LED display, supporting both heating and cooling relay control. With a wide supply voltage range (DC 12/24V or AC 110–220V) and a 1500W relay output, it is suitable for incubators, aquariums, fermentation chambers, HVAC control, and general-purpose temperature regulation projects. The included 1m NTC sensor provides accurate temperature measurement from -50°C to +120°C.
