Professional manufacturing is more secure and affordable. The company has professional temperature control technicians and advanced production equipment; perfect production technology; guarantee product quality; achieve safe production. Operation Guide 1. Turn on: Connect the power supply to an independent power outlet, and place the leakage protection switch (located on the back of the device) in the "ON" state. Press the power button on the panel to turn on the key equipment and display "8888" 4S, enter the standby state. The PV window displays the current measured temperature, and the SV window displays the current set temperature. 2. Start the circulating water pump: Press the "Circulation" button, and the indicator light corresponding to the circulating button lights up, indicating that the circulating water pump is turned on. (Note: Please turn on the circulating water pump before running other functions.) 3. Set the temperature: Press the "SET" key on the standby interface, the main display PV displays SP, the auxiliary display SV displays the set temperature, and enters the temperature setting interface. Press the key to increase the value and press the key to decrease the value. After modifying the setting value, press “SET†to exit the setting interface and return to the working interface. Under normal working conditions, the auxiliary display SV on the control panel displays the set temperature, and the main display PV displays the current measured circulating fluid temperature. 4. Stop the circulating water pump: Press the "Circulation" button, and the indicator light corresponding to the circulating button is off, indicating that the circulating water pump is off. 5. Start the compressor: press the "cooling" button on the working interface, and the indicator light corresponding to the cooling button lights up, indicating that cooling is allowed. If the set temperature is lower than the measured temperature, the "COLD" indicator starts to flash and enter the compressor Delay start protection time (factory setting 3 minutes), after the delay time expires, the compressor starts to work. 6. Stop the compressor: Press the "cooling" button while the equipment is running. The indicator light corresponding to the cooling button is off, and the compressor stops. 7. Start the conversion: press the "Conversion" button, the indicator light corresponding to the "Conversion" button is on, and the main display PV displays the temperature measured by the external probe (Note: this function is optional). 8. Turn off the conversion: press the "conversion" button, the indicator light corresponding to the "conversion" button is off, and the main display PV displays the temperature (circulating fluid temperature) measured by the built-in probe. 9. Start heating: press the "heating / constant temperature" button, (Note: "heating / constant temperature" function is optional, if there is no heating function, you do not need to press this button) The indicator light corresponding to the "heating / constant temperature" button is on Allow to heat. If the set temperature is higher than the measured temperature, the "HEAT" indicator starts flashing at this time, indicating heating. When constant temperature is required to maintain accuracy, the "heating / constant temperature" button must be turned on. (Note: The heating is PID controlled. Different equipment at different temperatures require different amounts of heat for cooling. At different temperature control points, different equipment will have different temperature control accuracy. More precise temperature control is required, so the constant temperature needs to be reached When the temperature is automatically entered into the auto-tuning adjustment, about 20 minutes can be constant temperature). 10. Stop heating: press the "heating / constant temperature" button, the indicator light corresponding to the "heating / constant temperature" button is off, indicating that the heating is stopped.
