Two LED digital heating thermostat controllers: XKW1088 and W1099. Designed for 220V mains use and built to deliver accurate temperature measurement and reliable regulation for aquariums, incubators, propagation chambers, and laboratory setups. The W1099 model also supports 24V DC operation for low-voltage or compatible systems. Why you need this product Maintain precise, stable temperatures without constant monitoring. Accurate measurement and automatic regulation reduce manual adjustments and protect temperature-sensitive animals, eggs, or plants. Compact, reliable control that fits into tight equipment layouts and performs in humid or incubating environments. Fast setup and broad compatibility let you use existing 220V heaters and equipment; choose W1099 when 24V DC operation is required. Key benefits and problem solving Accurate thermometer + thermostat in one: shows current temperature and actively controls heating to keep setpoints stable. Saves time and reduces risk: stable control prevents harmful temperature swings that stress fish, damage eggs, or disrupt germination. Flexible power options: both models run on 220V mains; W1099 adds DC 24V support for alternative power arrangements. Easy monitoring: bright LED display gives clear, immediate readings for quick checks and adjustments. Durable, space-saving design: compact, robust housing fits control panels or power strips and withstands demanding environments. Important attributes Function: digital temperature display and heating regulation. Compatibility: standard 220V mains; W1099 also supports 24V DC. Size/design: compact form factor suitable for control panels and tight installations. Construction: robust housing designed for humid or incubating environments. Performance: consistent, reliable temperature control to protect sensitive specimens. Practical use scenarios Aquarium: keep tropical or marine tanks at steady water temperatures to support health, feeding, and reproduction. Egg incubation: maintain exact incubation temperatures for poultry or reptile hatcheries to improve hatch rates and reduce manual intervention. Plant propagation and labs: control ambient or soil temperatures in germination chambers, propagation racks, or small lab incubators to ensure repeatable results. Simple to integrate, reliable in operation, and built for environments where steady temperature control matters. Models: XKW1088 and W1099 (220V mains; W1099 also supports 24V DC).
