Wide Application This adaptive temperature controller fits most 5in1 or 8in1 heat press machines with an overall size within 15' x 15' and working power below 2500W. It uses the original digital box with a dual LED display. Heat press machine is not included. Upgrade 'K' Type Chip The digital control box is built with a generation of K type upgraded circuit board and chip. It provides stable power and solves issues where the board operates unreliably due to voltage fluctuations. Note: this control box is only suitable for K type heat press machines. Time Temperature Dual Control Temperature range: 0480°F / 0250°C, with two selectable units. Timing range: 0999 seconds. The timing interface supports a variety of heat press configurations. Precision Security Control Equipped with an advanced digital control system and a bright LED display, the microprocessorbased design offers precision control and easy operation, while helping prevent damage to the heat press equipment. Practical use scenarios Garment transfers on compatible 5in1/8in1 machines: use precise temperature and timing to ensure consistent results when applying designs to Tshirts, hoodies, and similar fabrics. Batch production or workshop use: the hands timing feature allows operators to manage other tasks while the controller handles heat and timing for multiple items. Voltage fluctuation environments: the K type chip provides stable performance on compatible machines, reducing the risk of improper heating or timing due to power instability.
