Digital temperature controller with precise timing functions: timing start, timing stop, and timing switch. Simply plug in, select heating or cooling mode, and operate—no manual adjustment required. Features an LCD display with accurate readings. Measuring range: 50–99°C. Resolution: 0.1°C. Accuracy: ±1°C (within –20°C to 60°C). Compatible with 100–250V AC, up to 16A. Supports simultaneous connection to both heating and cooling systems. Independent differential settings for heating and cooling enable precise temperature control during significant fluctuations. Temperature alarm triggers when set limits are exceeded or sensor faults occur. Includes compressor delay protection and adjustable temperature calibration. Suitable for precise temperature regulation in greenhouses, aquariums, incubators, aquaculture systems, room climate control, and other applications.
