Digital Heating & Cooling Temperature Controller – Dual Relay Outlet
Plug-and-play dual relay temperature controller designed for automatic heating and cooling applications. Ideal for fermentation, aquariums, carboys, refrigerators, incubators, and controlled household environments.
This digital temperature controller provides automatic on/off regulation of heating and cooling devices through dual independent relay outputs. Designed for simplicity and reliability, it allows users to connect both a heater and a cooling unit for precise environmental control.
Operating across a wide temperature control range from -50°C to +99°C, the controller utilises a high-accuracy NTC probe sensor to deliver stable and responsive measurement. The clear digital display provides real-time temperature readings with 0.1°C resolution for improved visibility.
The unit includes programmable high and low temperature alarm functions with audible buzzer alerts, enhancing system protection during operation.
With universal 100–240VAC input compatibility and plug-and-play configuration, installation is straightforward without complex wiring. The controller can be used in a standing or wall-mounted position.
Common applications include:
-
Home brewing and fermentation (carboys, kegs)
-
Aquariums and reptile enclosures
-
Refrigerators and freezers
-
Incubators and brooders
-
Greenhouses and grow tents
-
Household temperature regulation systems
This controller is designed for general household and light-duty environmental control applications.
