The large LCD display screen provides clear and easy-to-read temperature information. Dual Heating and Cooling Functions: Equipped with dual heating and cooling functions, this controller offers automatic over-temperature alarm for enhanced safety. Easily control the temperature by setting the temperature value and personalized values. Aquarium Temperature Control: This multi-function device ensures stable aquarium temperature, promoting fish health and safety. Creating the optimal temperature environment for your fish has never been easier. Wide Temperature Range: With the ability to measure and control temperatures from -50 to 90℃, this advanced temperature controller ensures precise temperature regulation for various applications. Versatile Applications: Not only suitable for aquarium use, this equipment is also ideal for latory and other temperature control systems, offering flexibility and reliability across different settings. Specification: Condition: 100% brand new Item type: Temperature Controller Material: ABS flame retardant plastic case Color: As picture shown Weight: Approx. 130g Power supply voltage: 110-220VAC ± 10%, 50/60Hz (or DC12V / DC24V) Measuring and controlling temperature range: -50℃～+110℃ Resolution: 0.1°C Accuracy: ±1℃ Accuracy: ±1℃ Relay output contact capacity: Heating: 10A/240VAC, Cooling: 10A/240VCA Sensor h type: imported NTC sensor, cable length 1m/3.3ft Description: P0. Cooling and heating mode Please set to C for high temperature start as cooling mode Low temperature start is heating mode, please set to H P1. Hysteresis setting In heating mode (H): the measured value ≤ the set value-when the hysteresis starts to output the heating to the set value and stops. In the cooling mode (C): when the measured value ≥ the set value + hysteresis, the output cooling is started and the set value stops. P2. The highest setting range: the highest value does not exceed this value when setting the temperature P3. The lowest setting range: the lowest value when setting the temperature is not lower than this value P4. Temperature correction When there is a deviation between the measured temperature and the standard temperature, you can use this function to correct. The corrected temperature = the temperature before correction + the corrected value. P5. Delay start time unit: minute When controlling the refrigeration of the compression engine equipment, the delay time can be set according to the needs. The equipment will not start immediately when the controller is output, and it needs to start after the set delay time is run. P6. High temperature alarm When the measured value is greater than this value, the screen displays --- and an alarm will sound, and the output will be forcibly disconnected. P7.
