Chinese Diesel Heater Controller Instructions - Advanced Settings PIN Code 1688 How Change The Setup

1688 gives you access to alter many features on you Chinese diesel heater, in this video I
delve deeper into the setting of your Chinese Diesel Air Heater by accessing the advanced settings menu.
This 1688 pin coded section of the LED controller gives access to:
Pump dosage rate in Hz.
Fan speed in RPM
System voltage setting
Fan speed recognition magnets
Burner on/off control

It has proved to be a very reliable and efficient heat source for my motorhome.

Thanks for this Steve,
My heater, after a years use I might add, went nuts. The pump just wouldn't slow down. Purchased a new motherboard and heat sensor, installed them and no difference, pull it apart and cleaned everything, took out the glow plug and blasted light oil from spray can through the mesh around the glow plug. All back together and, , no difference, the pump was hammering away causing dark grey smoke.
There's no information anywhere on slowing your pump down, the basic settings are un-useable really.
Getting into the advanced settings is a revelation! Cheers for the pin code! I set the pulse to .8 and the fan 1500 - 5000 and she's behaving herself again! She belts out the heat until the temps up and then goes whisper quiet with the pump ticking over at a slow heartbeat, every now and then she speeds up to clear the excess fuel and slows right back down again.
Thank You Thank You!

I have one of these heaters... The "OF", while I don't know what it means, is not related to the burner. it is, in fact, a menu that allows that lets you change the factory PIN. The factory pin is in fact 1688 and I used this menu to change it to 6666, just to make it easier to get into the advanced settings. The rest of your descriptions for the settings are spot on.

thanks a lot, a Chinese friend of mine gave me a different heater with the numeric displays (not the graphical one)
She translated what was engraved on the displays unit so I could understand what was written on it and what the little computer was telling me.
Parts where missing or worn out, I bought them : a new heat plug (it was dead)
a new pump (it was missing) and a bunch of new stainless meshes (it cant be bad) it was so cheep and came fast!

your code 1688 worked perfectly and I was able to adapt the frequency to the new pump that was giving too much for this little unit.
now I have a heater to use on my sailing boat even "unplugged" at sea

thanks very much again

Thank you sooo much for making this video!!! Almost gave up on changing the fan speed and only keeping the pump on the lowest setting to stop it from overheating.

The SN setting 1 or 2 just after the voltage setting is about the number of magnets in the fanwheel.
Just open up the heater and look between te controllerboard and the fan while rotate the fan with your hand and count the little metal round objects in the fan.
If you count only one, then set SN to 1 and if you count two, obvoiously set SN to 2.
This has to do with an acurate measuring of the fan speed.

After playing with the setting I figured out you can set the rpm to 3500 for night time use about 2.5-2.7 pulse and the 1500rom idle at about 1.0-1.2 pulse at night in thermostat mode while sleeping

Mine was running far too hot, so thanks to you, i can now run it on 0.8hz

[perttukilpelainen]

Thank’s for the video. Thank’s to everyone for good tips in comments too. Going to adjusting for lower diesel consumption. ❤

Great info, I have written it down for my future hiccups:)
When I first set my unit up, it kept faulting with a E-006 code. It had never ran.
This is suppose to be a misaligned magnet setting on the blower
I reset the magnet pick up but every time I reset the power, it would fault out again.
I moved it in a step at a time & out a step at a time. Powering off the unit after each adjustment.
I read did in a post that if you held both arrow buttons in while reapplying the voltage it would clear the fault memory buffer. That fix it!
Now the only thing I can't figure out is the first screen after power up.
I has a message of message

Thanks for a great guide. Especially the info on the 16688 entry into factory settings. My unit was smelling like hot plastic and it would often cut out after 10 min with [E-05] (Overheating). I logged into the factory settings and adjusted the minimum fan speed to 1900 RPM which solved both problems. More air = cooler temperature of the heater but the heat is still distributed into the room.

[davidconner-shover]

when I first started mine, it belched smoke, fuel/air mixture settings are set by the max/min pump speeds against the fan speed (not by air mass)
I live at a high altitude, and quickly discovered that everything was set to sea level operation
I had to back off on the max fuel pump speeds against the maximum fan speed to find a happy medium; namely, it wasn't belching smoke, and the exhaust didn't reek of diesel fuel
these heaters don't shut off when the setpoint temp is reached, merely slow down to the lowest settings. so I set the minimum airflow rate to minimum, as well as the minimum pump speed, producing the least amount of heat

[ProblematicTube]

What I'm realising is most people don't understand the temperature setting. The controllable temp is what you are setting the fuel temp to be (it won't go higher than what you have set) the non controllable temp is the temperature of the heat exchange fins and therefore basically the temperature the air is getting blown out into the room. It's not the temperature of actual the room.

I was told in another video that theyre set in factory but theyre just set to run and work but theyre actually running rich. To set it up properly the way to do it is to set it to run on full power, then reduce the fuel pump so that it goes down to the 2nd to last bar, leave it a minute then turn it up so that the last bar only just comes on. Then it will run slightly leaner and use less diesel and run cleaner. Youre then supposed to run it on the minimum setting and adjust the minimum pump speed in the same way.

[NAldrighetti]

I somehow changed it to Fahrenheit in this menu. No idea how but I'll survive lol thanks for the info, I couldn't figure the menu out

[gregoryosborn]

If it gets to dirty and the flame keeps going out or not igniting turn max rmap down to 3500. It allows it to stay light and then after it's warmed up turn it back up to 4500rpm.

[henryha]

Thank you mate ! For adjust the voltage . Great video

[Nerd]

I run the low rpm at 1550 at 1.4Hz to prevent soot build up.

[gordonmitchell]

Perfect thanks for the details. All set now and looking (feeling) good. I love it when a plan comes together lol.

[LITTLEEXPERIMENTCHANNEL]

Thanks for this. Worked a treat fella.

[timt]

Without this video I’d have no idea how to change it from 24 to 12 as it arrived set on 24 and kept spitting out a E-01. Thank you!
