Digital Display Temperature Controller 0‑300 celsius High Precise Adjustable Thermostat 220V

Feature: 1. The temperature control range is 0‑300 celsius , high temperature and high precise control. 2. Intelligent digital display, easy to read data, adjustable temperature control switch. 3. After the thermostat is powered on, the actual temperature will be displayed, press the up and down keys to adjust the temperature. 4. Set the high temperature alarm value, if actual temperature exceeds this value, the screen and buzzer will prompt an alarm. 5. When the power button is normally energized, press once to power on, and when the power button is normally energized, press once to power off. Specification: Item Type: Digital Temperature Controller Material: Plastic Color: As Picture Shown Product Fixing Hole Distance: Approx. M3 86mm 3.4in Weight: Approx. 58.0g 2.0oz Temperature Control Range: 0 300 celsius Control Temperature Accuracy: 1 celsius Power Supply Voltage: 220V Data Storage: Yes Relay: 10A How to use: 1. Confirm the working mode and hold down SET for 3 seconds to display PO, press SET again to modify the PO value, H is heating mode, C is cooling mode 2. Set hysteresis value: Hysteresis is to start after the set temperature is stopped and the hysteresis value is added. The default is 2 celsius . If you need to modify it, please press and hold SET to enter P1 to modify. 3. Set stop temperature: After setting the mode and hysteresis, directly press ENT to confirm and return. At this time, the screen displays the real time temperature. Press a SET screen to display the stop temperature value, and then press the up and down keys to modify.Codes: CodesExplanation Setting Range Factory Settings P0 Heating cooling H C H P1 Return difference 3 30 5.0 P2 Set the maximum limit +300 300 P3 Set a minimum limit 0 0 P4 Temperature calibration +10 10 0 P5 Delay start 0 10min 0 P6 High temperature alarm 0 300 OFF P7 Data locking ON OFF OFF P8 Restore factory settings ON OFF OFFFirst. temperature setting After the thermostat is powered on, the actual temperature will be displayed. Press the SET key once and the screen will flash. Press the up and down keys to adjust the temperature. Second. Long press the SET button for 5 seconds to enter the system settings. After setting, press ENT to confirm and return. During normal work, long press ENT to shut down Third. PO: working mode When the thermostat is used for the first time, this value should be set. If it is used for heating and heating, it is set to H . If it is used for cooling and cooling, it is set to C . P1 hysteresis setting The return difference is the difference that the temperature controller needs to work again after it reaches the set temperature and stops. For example, if we set the heating mode and the temperature is 37 40 degrees, then the hysteresis is 3 degrees. P2 P3: Set limit height This function is to set the temperature limit range, not to participate in the design of the temperature setting. Under normal conditions, the setting range of the thermostat is 5 120. If you don t want that large range, you can use this function to shorten the setting value. range. If P2 is set to 50 and P3 is set to 20, then the setting range of the thermostat can only be set between 20 50. P4: Temperature correction This function is used for temperature calibration. If there is a deviation between the actual temperature and the actual temperature, you can use this function to calibrate. The corrected value = the measured value + the corrected value. For example, we measured the temperature to be 25.6 and the actual temperature is 25.8 degrees. Set to 0.2, then the displayed temperature is 25.6+0.2=25.8 degrees. P5: Delay start This function is generally used for compressor refrigeration. If you buy this thermostat for refrigerator or freezer, then this value must be set. According to the size of the back pressure sent by the compression, the general setting value is 3 6 minutes. If it is not for controlling the compressor or Delay function is not required, this value is set to 0 P6: High temperature alarm Set the high temperature alarm value. When the actual temperature exceeds this value, the screen and buzzer will prompt an alarm at the same time. At the same time, the output will be cut off to protect the safety of the circuit. The alarm is displayed on the screen as H H H , and the buzzer sounds di , di , and di . P7: Data lock If the set value needs to be protected to prevent others from modifying it at will, you can enter P7 and set it to ON after setting the parameters. After the setting is completed, the temperature and internal parameters cannot be modified. Unless you enter P7 and turn it off P8: Restore factory settings When the set value is out of order or malfunction occurs, you can enter P8 and turn it ON to restore the factory settings, or you can press the up and down keys to power on and restore the factory settings. Forth: Function Power on button: Press once to power on under normal power on state. Power off button: Press once to power off under normal power on state Plus key: press this key in the standby state to set up parameters. Decrease key: press this key in the standby state to set parameters down. Package List: 1 x Temperature Controller1 x Panel1 x Sensor2 x Screw2 x Nut
