re SN1 or SN2, according to manuals with my units(smaller print at end of manual), SN1 is the default, and is used for either having only 1 magnet on fan wheel or having 2 magnets of the same polarity facing sensor(all 4 of mine have 2 magnets and use the SN1 default setting), SN2 is also for 2 magnets, but with different polarities(ie 1 is north pole facing sensor and second magnet is south pole facing sensor). To fit a local (heatport voice multi controller) stop/restart temperature controller to one of mine(speaks what its doing when buttons pressed or for faults etc), i had a clearance issue with magnets hitting sensor, (new motor board supplied/needed as well) but found a mention somewhere, that they often can be pressed deeper into their holes, which fixed my problem. i run my other 2 (4th one is a spare) units at 1.5/8hz and 1500/5000rpm "AT SEA LEVEL" in my back porch(22ml pumps), and have never had a sooting up or smoking issue with them (4 and 5 years old now). One (claimed) 8kw one came with those settings, 2 other claimed 5kw ones came set to 5 or 5.5hz max originally, and last one bought came set to 1.4 / 7hz 1500 / 4500 rpm, so they vary a lot, but all are otherwise identical units in every way(white alloy case versions with chrome end cap). At 8hz setting, they all drink 0.5lts per hour at max output, but usually a bit less, as they throttle back via housing temp sensor unless porch is still very cold(which means no more than 4.5kw's as that's all the available energy in that amount of fuel. Lower settings will be proportionally less output than that(not checked, but guessing only around 3kw's at 5 hz.. (8hz output confirmed also by my calcs of delta t and airflow when i first got them). Just ordered another one today, will be curious what its supplied settings are (like the price drop over the years, first ones were$355nz, latest just $230nz delivered I did try one on a 28ml pump for while, but could never get it to run clean throughout output range, so gave up on it.

Great video! The manual isn’t very helpful, I have a question, mine has H1-6 instead of the temp,what does that mean? I can’t change the temp at all

Thanks! Very informative. I’m running mine on propane and changing these settings helps a lot.

Won't do anything. When pressing the setting 3times. Must have changed it

Thank God 🙏 A man knows what his talking about & explains thoroughly ✊✔️👍

Do you know, is possible to use heater only as fan? In summer, for air circulation and cooling. Thank you.

Really handy settings if you've got a smaller van, lower the pulse rate and the rpm and it'll run a little cooler so you don't need to keep turning it on and off again

thanks for brilliant vid just bought one, the so called instruction manual from H calory is useless this video as really helped me out all the best keith.

mine was on 1.7, went into settings, it would only go down to 1.6, put revs up to 1800, wonted to get the hz lower,

None of the codes work how would I find the code for my heater to get into settings

How do you change the temperature reading from Celsius to Fahrenheit ??

I have the black board on my 2019 diesel heater. The newer blue boards work completely different to the older boards. There's no altitude adjustment plus you cant disable the pass code also the startup fan and pump control runs different and there's no startup retry ect. The blue board is a cheaper version of the old black one plus you cant use veg oil or waste motor oil with the blue board.

Thank you for you chd controller info . I've tried all the ways that other tutorials show how to access the pump pulse rate ie Hz and up to now nothing has worked. I'll try your method the next time I'm in my workshop

There’s a water ski zone between oulton broad and near somerleyton it’s stretches for about 1.5 miles that’s why they circle ⭕️ and come back round think it’s between 4.30-8 in the evning there is a sight just up on the left hand side from where u r moored up that say water ski zone up there mate unfortunately for you wrong place wrong time it’s all legal

What’s the mooring’s fees like on a boat your size mate can you pay monthly or is it a annual thing I’m looking for a mooring for my Norman 21

What’s the rough price mate iv just brought a Norman 21 needs a new canopy.looks lovely in the gray mate nice looking boat that 👏

Nicest part of the river Waveney that is between beccles and geldeston lovely place in the summer to get the boat out 🙏🏻

Hi have you got a link for the motherboard and controller please

Is there a way to program this heater to come on at a certain temperature and turn itself off at a target temperature? Or does a person have to monitor the temperature of the space and turn it on and off manually? As in while you're sleeping and you are sweating and wake up and realize that the temperature is very hot in your sleeping space? Or if the temperature falls below freezing and you are freezing as well and realize that in order to not freeze to death, you must turn on the heater?

12 V is too low for your battery health. A fully charged battery should be 12.7 V and you should never drain it to more than 50% of its capacity which should be at about 12.2 V.

Hey, do you have any idea how to turn off the system completely? I tried holding on the power button but the fan kept blowing out cold air! I just ended up removing the fuze I had in

strewth it floats ????

Kind of you to help a fellow In need ,😊😊

Really think you should be using marine use silencer which is completely air tight, just a thought

Fuel filter's back to-front, it's supposed to fill the chamber then make its way through the gauze. Pump should be under the unit so it's pressurizing just fluid and no air .. .. .

Great video. Might consider having one put on my yacht for next winter. Although never drilled holes in a hull before and the thought of doing so scares me completely!

Oooh, I know that boat but I forget the gentleman's name. Usually bump (not literally) into him on Broads at Somerleyton.

Brilliant job well done helping a fellow boater

Finely a proper video on how to fit these diesel heaters on a broads boat and a video that’s straight forward and easy to follow Thank you and keep up the good work 100% liked and subscribed 👍

Great, easy to follow.

Very helpful.

Looking very nice.

Nice surprise seeing your friend.

It’s absolute madness between April-September on the river with all them hire boats no where near as bad on the south side most of the hire-boats stay the north side people who own there own boat tend to no get along with the hire boats they have no training and are always damaging other boats I stay well away from em on my speed boat

Nice job.

Nice place, camp site looks good for the prices.

Good capture first thing in the morning

Fancy making your dogs walk the plank :). Lovely scenery

On the pcb there is an hall sensor, on the new there is no one to see, how does it regulate?

60 mph winds? Really? 60 mph? The wind?

That top looks beautiful. What a lovely pice of wood.

Sitting it out is the best you can be by the look of it,

Our wheelie bin blew over today...i resisted the urge to call 999...instead, i picked it up and got on with my day. Just like you're doing. Stay safe.

Lovely sunset.

Love the look of that worktop and you make it look so easy to fit.

You must do so much research to keep coming up with these ideas.

Looks very nice, great finish.

That was very helpful to see the difference.

How much is it ?

That's a lovely little dog, she is funny.
