1Equipped with a large LCD screen, you can touch the button to operate, clear LED display for better readability. 2The sensor is specially precise machined and packaged. With moistureproof function, more stable and reliable performance. 3Suitable for water tanks, refrigerator, industrial chiller, boiler, steamers, industrial equipment and other temperaturecontrolled systems. 4Through safety and high reliability tests, strong antiinterference, suitable for all kinds of refrigeration and heating equipment automatic intelligent control system. 5Household intelligent thermostat, the shell is made of ABS flame retardant material, durable and wearresistant. Condition: 100% Brand NewItem Type: Temperature ControllerMaterial: ABSColor: As shown in the pictureOperating Voltage: AC220V10%, 50HZ/60HZOutput Load: 10A/220V ACPower: 3WWorking Environment: -10-50 : RH90%Control Range: -40-80Resolution: 1 Accuracy: 1Input Signal: One way temperature sensor, standard line length: 20k x 1.5m/4.9ft Parameter Description Set range Factory set value Annotation HC Cooling/heating function - C (Refrigeration) - CF Temperature unit conversion C= Celsius; F = degrees Fahrenheit C (Celsius) - d Temperatures return difference 1 ~ 15/ 60 2/5 Through this parameter, the target temperature can be stabilized in a certain setting range CA Temperature Calibration -15/-60~ 15/60 0 When there is an error in the measured temperature, the temperature can be corrected by using this parameter Pt Delay time 010 1 Protect the device from frequent startup HS Maximum temperature limit Control temperature +1 ~ 80/180 80 Prevent the temperature setting from getting too high LS Minimum temperature limit -50/ ~ Control temperature -1 -40/ Prevent the temperature setting from getting too low Note: HC menu selection H Heating C Cooling - One: Refrigeration Control1. When the current temperature is greater than or equal to the set temperature + the differential temperature (D) and the set "delay time (PT)" is delayed, the load relay picks up and starts cooling.2. When the current temperature is less than or equal to the set temperature, the load relay is disconnected, and the cooling stops.Two: Heating Control1. When the current temperature is greater than or equal to the set temperature + the differential temperature (D) and the set "delay time (PT)" is delayed, the load relay disconnects and starts heating.2. When the current temperature is less than the set temperature, the load relay is disconnected, and the heating stops.
