Temperature measurement range: - 50 to 110C (- 58 to 230C) ; Resolution: 0.1 at -9.9 to99.9, and 1 between other temperatures; Refresh rate: 0.5 s Two-color LED display: The temperature controller monitors the instrument and simultaneously displays the measured temperature (red) and the setting temperature (blue). Can be used in cooling/heating mode to test indoor or outdoor temperature Waterproof design: the NTC probe (10K 0.5%) is waterproof, and you can control the temperature at will, you can also control heating or cooling according to different needs Reliable to use: The electronic temperature control switch module has been tested for consistency and reliability, and its control accuracy is 0. 1 degree Celsius, reaction accuracy is 0.1 degree Celsius with high temperature protection Wide range of applications: electronic thermostat can be widely used in intelligent household and industrial appliances, appliances household, automatic irrigation, office machines, sound, automobile, Aquarium, aquarium and so on. Temperature adjustment: Press the button set for five seconds, then it enters the main setup menu, and press STC(+) and C/F(-) to move to P0 - P8. Press STC key and LED will flash. Press the STC(+) and C/F(-) keys to reach the setting temperature and wait 3 seconds before the module automatically saves the settings and exits. Index: < p>The light is on and the relay is closed; The lamp turns off and the relay turns off. LED display: Red: Measured temperature; Blue: setting temperature LLL: indicates that the sensor is on Hhh: indicates that the temperature is outside the module's measuring range : indicates that the module is protected at high temperatureProgrammable thermostat introduction (Code, description, setting range, factory setting): P0, heating/cooling, H/C, C< /p> P1, returns difference, 0.1-30, 2 P2, set maximum limit, + 110,110 P3, set minimum, - 50, - 50 P4, temperature correction, - 15 - + 15, 0 P5, delayed start, 0 - 10, 0 P6, high alarm temperature, - 50 - + 110, off P7, C/F, CS/FH, CS P8, factory reset, ON-OFF, OFF< /p>
