Features WIDE TEMPERATURE RANGE: The freezer temperature controller has a temperature control range of ‑40℃ to 50℃ and a temperature measurement range of ‑50℃ to 99℃ WIDE APPLICATION: 220V thermostat can be used in high power equipment, such as incubators, breeders, refrigerators, fermenters, greenhouses, etc. HIGH ACCURACY: The freezer temperature regulator has an accuracy of 1℉ to keep the temperature within the desired range, accurate and reliable ACCURATE AND EFFECTIVE: Dual temperature probe bring accurate measurement, designed for use in kitchen freezers, refrigerators, cooked food cabinets, etc. POWER SAVING DESIGN: With a power consumption of less than 3W, this temperature controller help you save on energy costs while maintaining the perfect temperature for your stored goods Specification: Item Type: Freezer Temperature Controller Material: ABS Voltage: 220V Output Current: 10A Power Consumption: Sensor Type: NTC, 25℃, resistance 10KΩ Front Panel Protection Class: IP65 Operating Storage Environment: -15℃~65℃, 20%~85%(no frost) How to Use: 1. Temperature Setting: In the measurement control state, press the ▲ or 、 key to adjust the temperature (shutdown temperature) setting. If there is no button operation for 5 seconds, the set shutdown temperature will be saved and return to the measurement control state. Temperature control output description: Cooling: When the cabinet temperature is higher than the temperature set value (corresponding to SET), plus control hysteresis(E3), and after the minimum interval time for compressor startup, cooling will start. When the cabinet temperature is lower than the temperature set value(corresponding to SET), cooling will be turned off. Resetting Output Parameters: Press ▲+T for more than 5 seconds, and the screen will display YES to restore the factory settings. 2. Power Switch: In the power on state, long press the heart key for 5 seconds to enter the power off state, and the interface will display OFF. In the power off state, long press the heart key for 5 seconds to enter the power on state, and the interface will display the measurement control status.
