Description: Temperature range: -20-100 ? Control temperature accuracy: 0.1 ? Display color: blue Power supply voltage: 12V Output: 1 Channel 10A Relay Enviromnment Temperature: -10-60 ? Humidity: 20% - 75% Dimensions: Approx. 79x 43x 26mm/ 3.11x 1.69x 1.02inch Hole size: Approx. 74x 9mm/ 2.91x 0.35inch Specification: How to operate: Circuit connection: reference circuit diagram connected to the power supply and load, then digital tube (on) shows the actual measured temperature value, digital tube (below) shows the preset temperature. Temperature sensor missing or damaged digital tube will display "- - -", before the buyer must check whether the temperature sensor is installed. The temperature control output for the 10A relay to meet a variety of high-power load, please ensure that the line is correct. Indicator light: Off indicates that the relay is off, indicating that the relay is closed Digital tube: display "- - -", 1, check the temperature sensor is missing or damaged 2, heating mode high temperature protection 3, cooling mode low temperature protection. In the protection mode the relay is automatically disconnected. Use of the keys: The thermostat panel has three buttons, key + key - set key SET Key +: to achieve rapid accumulation of values Press the key - to achieve the rapid decline in the value Key Restart: Restart button Key SET: to achieve the two-tier interface settings temperature settings interface parameter settings interface SET short press the digital tube (below) to achieve rapid temperature settings. Preset at -20 ?, 0 ?, 20 ?, 40 ?, 60 ?, 80 ?, 100 ? and other data sets to facilitate users to quickly call. For example: the user needs to set 68.8 ?, first short press SET to adjust to 60 ?, and then through the key to add fine to the corresponding temperature can be. Set up to wait for 5s to automatically save the data. Relative to the 1 generation thermostat 2 generation operation more convenient and flexible, dual LED display the measured temperature at the same time, set the temperature more easy to observe. Package Includes: 1 Piece Digital Temperature Controller
