Specification: Input voltage range: 105~240VAC Output maximum current: 10A Output power: up to 2000W Rated operating frequency: 50/60Hz Temperature measurement range: 1 ° C -99 ° C Temperature measurement accuracy: ±1 °C Temperature resolution: 1 ° C Product size: 145 *37 * 60 mm/5.7 * 1.4 * 2.4in Probe: NTC line length 2M Package list: 1 * Temperature Controller 1 * Power Cord 1 * Temperature Transducer 1 * User manual Precautions for use: 1. This product is not waterproof design, so the product can not be put into water when measuring the temperature of water, but the probe is waterproof, so you can measure the temperature of water by putting the probe into the water! 2, the input voltage can not be higher than 250VAC, otherwise it may damage the product! 3. Since this product is high voltage AC input and output, it is necessary to do a good safety grounding! Causes and exclusions: 1. No response after power-on, check if there is AC220V voltage input, and the plug wire is loose! 2. Display Er after power-on, check if the probe is connected and the contact is good! 3. After setting the temperature, the temperature relay is not connected, check whether the selected mode is correct, and whether the time constant temperature function is turned on! 1、The components of the machine are controlled by imported chips to control the temperature intelligently, suitable for a wide range of applications. 2、In the heating/cooling mode, the user can freely set the start/stop temperature. 3、Digital LCD display with clear readings and 4 buttons for easy operation. 4、Pre-wired, with plug, plug and play design, easy to use. 5、The indicator light indicates the working status, with timing function and over-limit alarm function.
