Switch Operating Instructions

Fuel Pumping Mode
After installation of the heater for the first time, the fuel pipe needs to be filled up with diesel. Only when the diesel entering the heater from the fuel tank, the heater could be
operated successfully.
Operation method: In the shutdown state, press and simultaneously. When the screen lights up showing “Polr”,release the button. The buzzer sounds once (release the button) to enter the Fuel Pumping Mode. 80 seconds later, the fuel pump will enter the state of rapid pumping (500 times of pumping diesel ). When the fuel pumping is completed and the diesel enters the heater, it will ignite and run automatically. If the diesel doesn’t enter the heater, the screen will display P—1 (Figure 3). Press the key at this time, and the system will start the fuel pumping procedure again.
The start times of the fuel pumping mode depends mainly on the length of the oil circuit. When pumping diesel, you can observe the progress of the fuel filling in the fuel pipe to judge whether it is normal.
NOTE: This chambre5is only for initial installation and when there is no diesel in the oil circuit. Do not use it at ordinary times to avoid flooding the combustion chambre.

Startup/Shutdown

  1. Click the ON/OFF key in the shutdown state (Figure 4),the screen lights up, the buzzer sounds once ( release the button ) and the heater is turned on. Then the screen will display the working status of the main components one after another. The fan works, the glow plug works, and the fuel pump starts to work 80 seconds later. When the flame mark appears in the outline of the screen host, the ignition is successful, and then it enters the preheating self-checking process.
  2. In the standby state, press and hold the ON/OFF key for over 3 seconds, the screen will display “OFF” (Figure 5), and the heater will enter the shutdown cooling process.
    When the cooling is completed, the screen will turn off and the heater will stop running.
    NOTE: Illegal power off is prohibited during the shutdown process.

Mode Setting
In the standby state, click the mode key to switch modes. Up button is to increase, down button is to decrease.

  1. When the screen displays P1.4Kw~P5.0Kw, it is the power mode. After adjustment, the power will be fixed and the heater will continue heating (Figure6).
  2. When the screen displays t 10°C~35°C, it is the temperature mode (Figure7).

NOTE: The two modes can only be switched and cannot coexist. The last setting shall prevail. For example, the previous setting of the power mode would be invalid if the temperature mode is set.

Remote Control Matching

In the shutdow state (Figure 8), press and hold the mode key “ ” of the control switch and the “OFF” key of the remote control at the same time.
The switch screen displays 433 (Figure 9), the buzzer sounds once, and the remote control and the control switch are successfully matched.
NOTE: Normally the remote control matching has been completed before the heater leaving the factory, and no further operation is required.

Timing Operation- Clock Synchronization
In the shutdown state, press and hold the clock knob to call out the clock icon, and then turn the clock knob to the left (1 bar). When the“Time”icon starts to flash, press and hold the clock knob , and when the hour digit flashes, you can turn the clock knob left and right to adjust. After the adjustment, click the clock knob . When the the minute and hour position flashes, turn the clock knob to adjust. After adjusting, wait for 5 seconds to complete the setting.

setting

Timing Operation- Single-period Timing
In the shutdown state, press and hold the clock knob to call out the time setting. turn the clock knob to the right, and the Number 1 to 24 would appear in sequence, representing 24 time periods. Set the time at what time the heater is required to work.
For example: We need to set the heater to turn on at 7:00 in the morning. Turn the clock knob to the right to adjust it to the number “7”, click the clock knob . At this time a solid yellow line will appear under the number “7” (as “7”). Five seconds later, the setting is completed.

Timing Operation-Multi-period Timing

  1. Continuous period work: press and hold the clock knob in the shutdown state to call out the time setting, and 1~24 time periods will appear in sequence. It takes several hours to work, that is, to set several time periods. For example: We need to set the heater to work continuously for three hours at 7, 8, and 9 in the morning. Turn the clock knob to the right to adjust to the number “7”, click the clock knob key, a solid yellow line appears below the number “7′”, and then turn the knob to the right to adjust the numbers “8” and “9”. Wait for five seconds, and the setting is successful.
  2. Working at Intervals: For example: We need to cancel the 8 o’clock among 7, 8, and 9 periods. Find the number “8”, and click the clock knob. The small yellow line disappears, wait for 5 seconds, the number “8” disappears, that is, the setting is successful. The heater will start working at 7 am, and shut down at 8am and start again at 9am.

Timing Close

Fault Code Fault Description Fault Analysis & Solutions
E0 Control unit error Replace the control circuit board.
E1 Failed to start (already tried twice) / failed to form a flame ① Fuel

exhaustion: Please check whether there is diesel in the fuel tank.
② There are bubbles in the oil line and the oil supply is discontinuous.
③ Fuel pump is failed to pump diesel: Replace the fuel pump.
④ Air inlet and exhaust are blocked: Check if anything stuck the air inlet and exhaust outlet.
⑤ White smoke at the startup time, black smoke, or too much carbon deposition.Unplug the oil inlet pipe, and start the heater to let it dry running till
the heater reporting fault. Repeat such operations for 3-4 times.When no smoke out of the exhaust pipe, connect the oil inlet pipe to start the heater to see if the ignition is successful.
