Plug & Play Waterproof Temperature and Humidity Controller Box

For Controlling Cooling, Heating, Humidity, and Dehumidification

Take full control of your temperature and humidity with this heavy-duty, plug-and-play controller. Designed for indoor and outdoor use, it features a waterproof control box and a sensor housed in a protected enclosure with ventilation holes, allowing installation in humid or outdoor environments.

Simply plug in your devices (heater, cooler, humidifier, or dehumidifier), install the waterproof sensor, turn on the power, and set your desired temperature and humidity. The controller automatically manages the climate based on your settings.

Smart Dual-Output System with Safety Protection

  • Built-in Dual 10A Circuit Breakers – Ensures safety for both outputs, preventing electrical overloads.
  • Configurable Heating or Cooling Mode – Supports both heating and cooling functions based on your needs.
  • Humidifier & Dehumidifier Control – Switch between humidification and dehumidification modes effortlessly.
  • Buzzer & Flashing Alarm – Alerts you when preset temperature or humidity limits are exceeded and automatically shuts off outputs to prevent damage.
  • Memory Function – Records maximum and minimum temperature & humidity for seasonal adjustments and efficient performance.
