Refrigerating control output delay protection5. Alarm when temperature exceeds limit or sensor error6. Memory function: settings can be saved when power off7. Wide Application: domestic freezer, water heater, fans, refrigerator, industrial chiller, steamer, industrial equipment and other temperature control applicationsParameters:Item No.: STC-3000Display: /Modes: Heating and CoolingTemperature Measuring Range: -50 ~ 99 (error: ±0.5)Accuracy: ±0.1 (-50 ~ 70)Resolution: 0.1Working Temperature: 0 ~ 60Relative Humidity: 20~85% (no condensation)Sensor error delay: 1 minutePower Supply: AC 110V~220V / DC12V/ DC24V<; 3WOutput Relay: 2 Relays: Cooling & Heating both 10A220VACNTC Probe Sensor 100cmDelay start and temperature calibration Function YESMounting Hole Size 71x29mmDimension: 75x34.5x85mm (LxWxD)Menu InstructionCodeFunctionSet RangeDefaultF1Set Temperature Value-50 ~ 99.910.0F2Set Difference Value of Temperature0.3 ~ 10.00.5F3Compressor Delay Time1~10 Minutes3 MinutesF4Temperature Calibration Value-10.0 ~ 10.00F5/ Conversion/0/1Packing List:1x Temperature Controller + 1x NTC Probe Sensor + 1x ManualPanel IllustrationPower Switch Set Key UP Key Down KeyIndicator Light Measured Temperature NTC Probe SensorIndicator Light Status InstructionIndicator LightFunctionCool Indicator LightOn: Refrigeration starts / Off: Refrigeration stops / Flash: compressor DelayHeat Indicator LightOn: Heating starts / Off: Heating stopsSet Indicator LightOn: Parameter setting statusKey operation instruction1. View parameter:When the controller is working normally, press and release the "" button once, display the temperature set value, press and immediately release the "" button once to display the temperature difference set value, 2 seconds to normal temperature display state2. Set the parameter:When the controller is working normally, press and hold the "S" button for more than 3 seconds to enter the modified parameter mode. The indicator light is on, and the digital tube displays the code "F1" of the first menu item.Press "" or "" to adjust up or down the menu item and display the menu code. Press "S" to displays the parameter setting value of the current menu.Hold on the "S" key and press and hold "" or "" to adjusted up or down and the parameter setting value of the current menu is displayed. While holding down "S" and "", the key or "" key can quickly up or down and display the parameter settings of the current menu.After the completion, press and release the power button to save the parameter modification and to the normal temperature display state.If there is no key operation within 0 seconds, the parameter modification will not be saved and to the normal display state."Er" is displayed if an error occurs while saving the parameter, and returns to the normal display state after 3 seconds.3.Repair system data:When the machine is powered on, first check whether the parameter setting is normal. If the check is wrong, it will display "ER". Pressing any key at this time will restore the default parameter settings and work normally. It is recommended to reset the parameters at this time.Operation instructionUnder controller normal working status, press and hold "(I)"key for 3s can turn off the controller; Under controller "off" status, press and hold "(I)" key for 1s can turn on the controller.Under the controller normal working status, screen displays the current measuring 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 temperature value >= temperature set value + difference value, and the refrigerating relay is connected; If the "Cool" indicator light flashes, it indicates the refrigerating equipment is under compressor delay protect status; when the measuring temperature values 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, the heat relay connects; When the measuring temperature >= temperature set value, the "Heat" indicator light is off, and the heat relay disconnects.Error/Alarm descriptionAlarm when sensor error: Controller activate the sensor error alarm mode when sensor open circuit or short circuit, all therunning status is closed off with the buzzer alarms, and the nixie tube displays "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 the measuring temperature exceeds temperature measuring range:Controller activates the error alarm functionwhen the measuring temperature exceeds the temperature measuring range, all the running status is closed off with the buzzeralarms, and the nixie tube displays "HH",Press any key can cancel alarm sound, system back to display the normal working mode when the temperature restore to normal measuring range.Safety RegulationsDanger:1. Strictly distinguish the sensor down-lead, power wire and output relay interface from one another, and prohibit wrong connections or overloading the relay.2. Dangers: Prohibit connecting the wire terminals without electricity cut-off.Warning:Prohibit using the machine under the environment of over damp, high temp., strong electromagnetism interference orstrong corrosion.Notice:1.The power supply should conform to the voltage value indicated in the instruction.2.To avoid the interference, the sensor down-lead and power wire should be kept a distance./ ConversionWiring WaysIndependent power supply for loadSame power supply for load
