Good quality and simple: start time, stop time, and timer; just plug in and select the heating or cooling system to make it work, no wiring required, accurate LCD readings. Temperature control range: 40–120°F. Operating temperature differential: 1°F. Reset temperature: 1°F. Operating structure: self-reset. Electrical contact type: 1NC. Lead length: 1.8 meters. Product specifications: Digital temperature controller compliant with European regulations, suitable for 100–250V, 16A (max). Supports simultaneous connection of heating and cooling systems; heating and cooling functions can be set separately to manage temperature during rapid changes. Temperature alarms activate when limits are exceeded or sensor errors occur, reducing the need for constant monitoring. Includes compressor delay protection; temperature calibration is also supported. Widely used device: Enables precise room temperature control. Ideal for use in greenhouses, fish tanks, carbon crystal heating panels, aquaculture, incubators, home temperature management, and similar applications. Note: Due to variations in monitor display colors, the actual product color may differ slightly from the image shown.
