H1 to H6 diesel heater controller: Alpine mode, priming
Updated
This panel looks like the classic 5-button LCD but behaves differently: heat is set in levels H1 to H6, there is no pump-rate setting, and one owner who tried codes on its code-entry screen reached no settings. Guides that tell you to enter 1688 may not apply to it. The procedures here come from owner videos. The Vevor CY and Liwolf manuals describe a five-key H1 to H6 panel with a plateau mode and E-2 to E-10 codes, which is probably the same design; see the E-2 to E-10 panel page for what those manuals say.
Is this your controller?
Also called: new controller, the other type, Alpine-mode controller
The same black case and five buttons as the classic LCD, so you cannot tell them apart until the panel is powered. Once lit, manual mode reads H1 to H6 with a bar graph instead of a Hz figure, and the battery voltage is shown on the main screen.
How it shows a fault: One owner quotes short codes without a leading zero (E2 for a voltage fault, E8 for flame-out). That matches the E-2 to E-10 table in the Vevor CY and Liwolf manuals, which describe a five-key panel with H1 to H6 gears.
Reported on: unbranded van-install kits, Likaci (a 6-key variant).

Procedures on this controller
Prime the fuel line Owners
Press and hold up and down together. The pump runs while they are held and stops a few seconds after release. Three owners describe this independently.
A few seconds at a time is enough. Owners who show this warn that over-priming floods the heater and makes it smoke.
High-altitude (Alpine) mode Owners
Press and hold settings and OK together until a mountain icon appears at the top of the screen. Do the same again to turn it off. Owners say it lowers the pump rate.
Switch manual levels and automatic temperature mode Owners
Hold the settings button. In automatic mode the display shows the set point and the actual temperature, and up and down change the set point.
Known quirks
- A timer shut-down is final: the heater does not restart when the room cools.
- One owner reports this panel works with a different control board and cannot be swapped for the classic panel.
- If your H1 to H6 panel shows codes written E-2 to E-10, use the table on the E-2 to E-10 panel page.
