This multifunctional timing temperature control socket comes with a clear backlit LCD display, allowing you to read temperature data and set parameters effortlessly even in dim environments. Integrated built-in backup lithium battery retains all scheduled and threshold settings after power cuts, avoiding repeated reconfiguration. It supports accurate temperature monitoring with external probes, flexible heating/cooling mode switching, and 7-day cyclic timing programs to automate your equipment. When temperatures go beyond preset ranges, it triggers automatic power on/off to stabilize ambient conditions. Flame-retardant shell and standard outlet design support stable load, paired with overheat and overload protection for safe round-the-clock operation. Compact and easy to install, it works perfectly for reptile tanks, fermentation boxes, greenhouse heaters, aquariums and seed incubators. Combining timing, constant temperature and memory functions, it cuts manual maintenance work and optimizes energy consumption for household and small commercial constant-temperature equipment.
