Working process: described under the premise of factory setting

Power on for about 5 seconds to complete the power-on process and enter the OFF state. Press the “Start/Stop” button to enter the warm-up state, display the current temperature and target temperature and the gear position. The output of the heat pipe has an output to start heating, and the preheat lamp lights up. When the temperature reaches 130 °C, the running light starts to flash, indicating that you can start the vaporization ignition by pressing the “Start/Stop” button or the key. After the start, the running light will turn to the normal light, and the ignition and electromagnetic pump will start to output and simultaneously ignite and vaporize the light. On, after 6 seconds, the ignition output stops, the ignition lamp also goes out, and it enters the combustion state. At this time, there is still output at the output end of the heating pipe, and the preheating lamp is still lit until the current temperature reaches the target temperature to stop the heating output and extinguish the preheating lamp.

After the current temperature reaches the target temperature, if the operation is not started by pressing the “Start/Stop” button, the system enters the thermal insulation working state, and the heating and heating is automatically performed. The temperature of the burner is always maintained near the target temperature, ready to start working.

During the combustion process, press the “Increase” button to gradually increase to the maximum gear position. Press the “Decrease” button to gradually decrease to the minimum gear position, then reduce the work stop. Press the “Add” button to turn it on again.

After the machine is stopped, press the plus button, rocker switch or precision adjuster to start the machine. It is started from the gear position before stopping.

After the machine is stopped, press the start/stop button or press the precision regulator to start it from the default gear position of the system.

Press and hold the “Start/Stop” button for about 3 seconds during the warm-up or combustion work, and the system will enter the OFF state. Precautions:

★ The temperature value does not rise and fall during the heating process, indicating that the polarity of the thermocouple is reversed.

★ When the highest-grade setting value is too large and the pump oil exceeds the vaporization capacity of the burner, flame instability will occur.

★When the starting temperature setting value is too low, the flame will be unstable due to insufficient vaporization.

★The controller adopts the instrument structure design, and its structure itself does not have waterproof function. It is suitable for being embedded in the control box panel. It is required to have the sealing structure and related sealing measures to ensure that the circuit will not be damaged due to moisture ingress.

★ If you find that the flame is unstable when you just click it, you can set the ignition to delay a few seconds to start the ignition, and at the same time, raise the starting temperature appropriately, that is, try to make the vaporization working state stable and re-ignite. Experience has shown that this effect will be much better. .
