4.2 key: Switch between running/standby mode.

4.3 Key: Open the parameter setting interface, select the setting item, and after completing the parameter setting, long press the key for 5 seconds to exit the setting interface. (Automatically exits after 15 seconds without any key action).

4.4 Key

■ Setting status: Click - Set numerical increment; Long press - Set the value to increase rapidly.

4.5 key

■ Setting status: Click to set the numerical value to decrease; Long press - Set the value to quickly decrease.

Alarm status: Cancel the sound and light alarm, and after troubleshooting, clear a fault memory with each press.

4.6 Key

■ Standby mode: Press the button to manually turn on the circulation pump, and then press this button to turn off the circulation pump;

■ Setting status: Press the button to jump to the next line of settings.

4.7 key

Alarm status: Press the key once to display the cause and solution of the alarm, then press the key to exit.

5.3 Timer Function Settings

In the settings interface, press the key to bring the cursor to "time period setting" and enter the time period setting interface. Press the key once to set the first time period, use the key to set the time to be set, press the key again to bring the cursor to "stop", and then press the key again to select. A time period is turned on, press the key again to return to stop using it, and use the key to select the time period to be set. The method for setting other time periods is the same. Press and hold the key to exit the settings interface. After using time period control, if it displays "within the time period", if it is not within the time period, it displays "outside the time period"

5.4 Operation

Press the button, and the controller will enter standby mode after self checking for 3 seconds.

If there is a fault, it will sound and light an alarm, and display the name of the fault source at the same time.

Press the button to put the controller into operation.

When the outlet water temperature is lower than the set value of "shutdown temperature", start the burner or heater; When the water temperature reaches the set value of "shutdown temperature", turn off the burner or heater.

Restart the burner or heater when the water temperature is below the "ignition temperature"

5.5 Manual

Press the button to start the manual circulation pump in the "System: Standby" state, and then press the button again to select to turn off the circulation pump.

6、 Alarm

6.1 Overtemperature alarm

When the oil outlet temperature exceeds the set value of "over temperature alarm", the controller enters over temperature alarm protection, the buzzer sounds an alarm, and displays "over temperature"; Simultaneously turn off the burner or heater.
