It back to display the normal temperature display status in 2s.2.The way to set parameter:Under controller normal working status, press"SET" key for 3s or more to enter parameter modifying mode, and the "SET" indicator light on, screen display the first menu code"F1". Press"" key to avoid the interference, the sensor down-lead and power wire should be kept a distance or "" key to page up and page down menu item to find accordingly code, press"SET" key to display the parameter set value of the current menu. press and hold "SET" key, press "" key or "" key again to adjust up and down the parameter setting value of the current menu item. Press and hold both "SET" key and "" key or ""key simultaneously to choose and adjust the parameter value of the current menu value promptly. After finishing the setting, press and release the " " key instantly to save the parameter modified value and to display the normal temperature value. If no key operation within 30 seconds, system won't save modified parameter, screen back to display normal temperature. Screen display "Er" if error appears during parameter saving, and back to normal working status 3 seconds.3.Restore system data When electrified, system will check itself, screen will display "Er" if error exit, please press any key at this time, and it restore default value and enter into normal working mode. It is advised to reset the parameter value under this conditionOperation instructionUnder controller normal working status, press and hold " "key for 3s can turn off the controller; under controller "off" status, press and hold " " key for 3s can turn on the controller.Under the controller normal working status, screen display the current temperature value; also the controller can also switch the working mode between heating and cooling.Controller starts refrigerating with cool indicator light on when the measuring temperaturetemperature set value+ difference value, and the refrigerating relay is connected; the "Cool" indicator light flashes, it indicates the refrigerating equipment is under compressor delay protect status; when the measuring temperature temperature set value, the Cool indicator light on, and refrigerating relay disconnects.System starts heating when the measuring temperature value the temperature set value-difference value, and the "Heat" indicator light on, and the heat relay connects; when the measuring temperature temperature set value , the "Heat" indicator light is off, and the heat relay disconnects.Error descriptionAlarm when sensor error: controller activate the sensor error alarm mode when sensor open circuit or short circuit, all the running status is closed off with the buzzer, and the nixie tube display "EE", press any key can cancel alarm sound, system back to display the normal temperature when the error and the fault is cleared.Alarm when he measuring temperature exceeds temperature measuring range: controller activates the error alarm function when the measuring temperature exceeds the temperature measuring range, all the running status is closed off with the buzzer alarms, and the nixie tube display "HH", press any key can cancel alarm sound, system back to display the normal temperature when the error and the fault is cleared.2,To avoid the interference, the sensor down-lead and power wire should be kept a distance.**The working power supply voltage must be connected according to the standard voltage of the label, otherwise the module will be damaged easily.Dual LED DisplayTemperature controller instruction manualTemperature control range: -55°C~120°C/-67°F~ 248°FTemperature control accuracy: 0.1 °C / 0.1 °FDisplay color: red + blueWorking power supply: DC12V DC 24V AC110V~220VSensor: NTC 10K 1 Meter (with probe)Product Size: 79.2mm×41.9mm×26.3mm Hole Size: 72.1mm×39.2mmProduct weight: 52g(12V/24V),59g(110V~220V)Operation and display panelOperation guide1. Short press "SET" small digital tube to flash, press "" or "" to set the target temperature, press "Standby" button or no operation to save the setting within 3 seconds.2. Press and hold "SET" to enter the code setting mode, press "" or "" to switch the code. After selecting, press "SET" to enter the code setting. After setting, press "Standby" button or no operation to save the setting within 3 seconds. .3. The last parameter setting is saved by default after shutdown.4, restore the settings: press and hold "SET" to power on.5. When the module is powered on, it will start directly. After power-on, press and hold the "standby" button, the module will enter "sleep" or "wake up"; in case of power failure, the module will run automatically after power recovery, no need to start manually.**The working power supply voltage must be connected according to the standard voltage of the label, otherwise the module will be damaged easily.69649More To Love==========Battery Included : NoHigh-concerned chemical : NoneMeasure Type : KScrew : M6*1Cable Length : 1mType : KTheory : Temperature ControllerDisplay Type : DIGITALPower Type : ChargerCertification : Model Number : W3231 Digital Temperature ControllerMax Measuring Temperature : 100°C - 119°CStyle : EmbeddedIs Smart Device : YesUse : IndoorDisplay Size : 1.9 Inches & Under
