How to use the rotary controller for a Chinese Diesel Heater

[@Efntodd]

I bought this basic rotary controller based iff this video and happy to say it works as advertised. Much simpler to use than the digital version that came with the heater originally

[@berko79]

Yeah I agree, often simple is the easiest/best :)

[@EsssTeeeBeee]

Any idea how to change from 24v to 12v with this controller?

[@NathJcb17]

Great video! Its all new to me, just installed my heater in the workshop tonight, as far as i understand when you turn the wheel on your controller it just adjusts the fan speed? What about the temperature? Thanks

[@berko79]

Yeah you are correct it adjusts the fan speed. The interesting bit about how they work is the fan speed is not just for the hot air it puts out which warms us up. The fan speed is also for how much air it pushes into the combustion chamber and in turn how much fuel gets injected (more air more fuel = more heat). So yes the temperature/amount of hot air produced goes up with the fan speed.

@@berko79 ah right ok, thanks for the reply

How about outlet temperature?? Is 40c??

[@LarryAusley]

Were you able to locate a set of written instructions for this controller?

[@berko79]

No, I wasn't able to find any instructions at all for this controller. That's part of the reason I decided to make this video. Luckily it's pretty simple but things like the error codes is a bit different and could easily be missed.

I have one on my heater and it works great

[@berko79]

Yeah I am beginning to think this is the pick of the bunch to be honest. Just simple and works!

[@dirkbertels3872]

Thanks for that. My rotary controller only works on heaters with '6 blade' controllers (not on the ones that use the newer '3 blade' controller). Or to be more exact, it works on heaters that have a motherboard that work with 6 blade controllers. I bought the rotary controller as a spare in case the LCD controller fails. It flashes when there's an error, e.g. 7 lights flashing means error 07. I would use it if it had remote control as well.

[@berko79]

Yeah different circuitry in the 6 and 3 blade controllers and they arent compatible. I'm not sure if they make a rotary controller which works with the 3 blade.

[@nobody-xt3zg]

7:31 what is the blower / heater outlet temp in low and hi setting?? Is the heating power allso reduced or just fan speed?? Is the air temp 30c or 80c in low setting??

[@andrewdunlop84]

Rotory dial is for the fuel pump speed not so much the fan itself, fan does eventually slow a bit according to fuel input

[@brianbaird6528]

Does anyone know how to change from simple Hz adjustment to actual temperature adjustment. I got mine changed over to Hz somehow and I can only adjust the power output with the knob. It used to rev up and slow down automatically with temperature. I want to set it back the way it used to be, but don't know how to do it.

[@glenwelder]

Is the dial adjusting the hertz .

[@berko79]

Both the hertz and the fan speed. Well the fan speed is tied to the hertz of the pump so if one changes the other has to

[@snapcrack55]

When I replaced mine with a simple controller, it wouldn't work & flashed the 7th lights.

[@berko79]

E07 is communication error (see in the description for a full list). I'd say your controller is not compatible with your heater ecu board. You'll need to replace the control board inside the heater to make it compatible. I'm guessing your old controller, which it may look the same as mine, might be the featureless one they bought out.

[@snapcrack55]

@berko79 thanks. Which controller board do I buy?

[@bevsmyth7258]

Can you use a remote

[@berko79]

no, these controllers dont support remotes

[@bevsmyth7258]

@@berko79 thanks for that information

[@rudbeckia885]

Your description of connector was impossible to see

[@GearheadologyGarage]

Ok so I’m not the only one that noticed the rotary knob isn’t calibrated for shit when you just want to turn it up one click it’ll jump 4-5 speed settings really quick it becomes annoying smh

[@jeffreywiley3654]

BUY a kerosene kerosun style instead easy quiet just light outside then move indoor and turn off outside just make sure the wick is completly out before you walk away, blow on it. these work great.

[@Fj-fe6co]

Great

[@jeffreywiley3654]

These heaters should be outlawed until they can produce a working heater controller I bought 2 diff brand heaters junk bought the knob junk bought all new mother f er board still nothing, dont waste your money, these companies are running a ponzi, also pluged into wall, running car, also seperate battery and charger, charger by its self. junk.
