Features Working Range: The temperature control range of this controller is ‑40℃‑50℃, the temperature measurement range is ‑50℃‑99℃, with high accuracy. Multiple Usages: 220V temperature controller can be used for high power equipment, such as incubator, breeder, refrigerator, fermenter, greenhouse, etc. With NTC Sensor: This electronic temperature controller adopts NTC sensor with a resistance value of 10KΩ, ensuring accurate and stable measurement. IP65 Protection: The front panel of this thermostat has IP65 protection, which can be used in more high and low temperature environments, safe and durable. Easy Operation: With clear digital display and button operation, this electronic temperature controller is convenient to use, suitable for home or industrial use. Spec: Item Type: Temperature Controller Material: ABS Voltage: 220V Output Current: 10A Power Consumption: Sensor Type: NTC, 25℃, Resistance 10KΩ Front Panel Protection Grade: IP65 Operating and Storage Environment: -15-65℃, 20%-85% How to Use: 1. Temperature Setting: While in the measurement and control state, press the upper or down key to adjust the temperature (shutdown temperature); if there is no key operation for 5 seconds, the set shutdown temperature will be saved and return to the measurement and control state. The temperature control output is described as follows: Cooling: When the freezer temperature is higher than the set temperature value (corresponding to the SET temperature setting value) + control deviation (E3), and the minimum interval time for compressor startup is completed, cooling starts. When the freezer temperature is lower than the set temperature value (corresponding to the SET temperature setting value), cooling is turned off. Parameter Reset: Press upper and T for more than 5 seconds, the screen will display YES to restore factory settings. 2. Power On Off: In the power on state, press and hold the on off key for 5 seconds to enter the power off state, and the interface will display OFF. In the power off state, press and hold the on off key for 5 seconds to enter the power on state, the measurement and control state will be displayed. Package List: 1 x Temperature Controller Note: 1. Strictly distinguish between sensor leads, power lines, and output relay interfaces, and do not connect them incorrectly. The power supply voltage must not exceed the rated voltage range of 220V ± 10%. Wiring connection must be done with the power disconnected. Package List 1 x Temperature Controller
