STC-1000 Temperature Controller DC 12V 10A Digital Thermostat with 2 Relay Outputs and NTC 10K Sensor for Heating and Cooling Temperature Switch

Power supply: DC 12 V; Maximum charging current: 10 A; Dimensions: 85 x 75 x 35 mm; Power consumption: < 3 W; Operating temperature: 0 - 60 °C. Equipped with 1m waterproof NTC probe, high precision, for precise and stable temperature control (accuracy: 0.1℃). Display in degrees Celsius, relay output. Heating mode (start temperature < off temperature); Cooling mode (start temperature >off temperature). F1: Cut-off Temperature (-60–120 °C); F2: Hysteresis (-0.1–30 °C); F3: Cool Down Delay (0 to 10 minutes); F4: Temperature Correction (-10.0 to 10.0 °C). Suitable for compressors of air conditioning systems, freezers, refrigerators, air conditioners, fermentation chambers and refrigeration units that require automatic switching between cooling and heating. The current temperature is 28 ℃ and the desired cooling temperature is between 24 and 23 ℃. Setting: Set F1 (stop temperature) to 23.5°C and F2 (hysteresis value) to 0.5°C.
