Gary the gadget guy'day, have got a Brivis HE30 main heating system, the a single with the Networker panel. It functions great - possess acquired it for just over 3 decades today. About 5 a few months back where we acquired to have Brivis out under guarantee to change a 'sticking' thermostat that produced the unit believe it was getting excessive over-temp inside the device (typical problem apparently). He also observed that the unit was 'cycling', frequently going over-temp inside then switching off the gasoline putting fan on 'highest acceleration' to clean it, and that would circuit around every few moments.

He set that by adjusting the computer to a much better fan-speed só it didn't period so significantly. Now that the unit is simply outside of its guarantee, wouldn'capital t you know it, there is another problem. Some ducting opened up up under the house, so minimum high temperature, but easy more than enough to fix. (use even more duct recording). That it opened up up/split was most likely due to a quantity of stuff, plumber/myself moving over/under/manhandIing some of thé ducting under thé house while doing graywater cable connections. Where it opened up was in the primary duct out from the unit, about 2 metres from the unit, where another temperature sensor will go 'into' the duct.

I recorded it all back upward, but since after that there is a little spanner displaying on the Networker board, although the unit is otherwise working good, generating great warmth, all the relaxation. Since its out of warranty, i'd instead not have got another service callout fee (hundreds of $$) for what will be most likely a mistake i've already cleared by re-áttaching the ductwork.

l don't imagine anyone right here has the Brivis He or she30 service manual from the 'seller' section of that they'n be ready to posting? Ok, got a stage further right here. The device DOES provide me an mistake quantity, its error # 31 on H01. Since this isn'capital t in any manual i possess, i called Brivis, they inform me thát its the AFR0 sensor which will be a safety issue that evidently detects 'fire in the return wall plug'.

If its attempting to fixed fire to the ductwork. Its not regarded as a 'essential problem' and as like doesn't prevent the unit from operating. Error #31 particularly means that it offers gone open-circuit ón the sensor, só its burnt up or shut off in some manner.

Through my google-fu skills, i present which does point out the 'AFRO sensor'. I also found a TradeLink components checklist which has the sensor outlined on page 162. Would still appreciate to have got a copy of the service guide if anyone right here has it.

Does anyone have any experience with fixing a Brivis main heating device? A little bit of history: A while back again I acquired difficulty with a electric circuit intermittently stumbling the routine breaker. I primarily thought that I had a faulty appliance so I did an insulation breakdown check on all the devices. All of them examined out okay except for the central heating device that demonstrated a little bit of leakage. I remaining the main heating device unplugged, but the tripping remained.

The tripping problem was eventually discovered to be a animal chewed cable. This has been repaired by an domestic electrician. In the procedure, the strength outlet to the central heating unit (fitted by the heating system installer) had been sent with the energetic and natural transposed. This has been fixed up too. The issue: The main heating device has been still left unplugged for various months right now, but I thought I should connect it in in preparation for when it is next required.

At initial, nothing occurred when I plugged it in (ánd l didn't anticipate anything to occur). Nevertheless, when I examined the control within, the display screen was still blank. I thought that maybe I plugged it in but had forgot to change it on?

I proceeded to go under the house again to check out. It was on, so I thought I'd try out the additional wall plug (its a dual electric outlet) just in situation. When I connected it in to the various other outlet and changed on - something unforeseen happened. It went Hammer! And there has been a display near the right-hand part vent (the one nearest the 'superstar' label). I converted everything off and taken out the cover to appear for any apparent troubles.

The nearest I can tell, is that the flash may possess long been near the blowing apparatus motor. The motor rotates really freely so I'm not really persuaded it is usually the electric motor. Furthermore, l didn't reaIise it at thé time, but the signal breaker tripped too. Does anyone possess any tips or pointers as to what might end up being wrong?

I'll possibly have got to wait until the weekend before I have got period to look more. Any guidance and assistance would be much valued. I have got a Brivis He or she30 here.

From memory when you regain mains power nothing at all happens until you hit 'strength' on the Networker section. Nothing shows up on thé LCD inside thé unit itself. One point that does appear a little bit odd is certainly that to my mind your device is definitely on its aspect.

At least for a HE30, its all top accessible, not really side-accessible. lf thats the case maybe having turned on energy while its on its aspect is usually an concern? As much as what 'blew', its not most likely to become the electric motor as it would not really have energized the engine as yet, it only does that when it can be converted 'on'. From storage there is certainly a blend for the internal controller, maybe notice if you can discover that. Also follow the mains wires and discover where that goes.

Maybe something is certainly open that should not be? As considerably as what 'blew', its not most likely to become the engine as it would not really have energized the motor as however, it only will that when it is definitely transformed 'on'. I'michael a little puzzled by that as well. The 1st time I turned it on, nothing occurred at all (which is usually normal). When I went within to verify the 'networker' it has been still completely blank (no period, no soft key menus). I did strike the strength key on the nétworker but it didn't appear to create any difference. However, when I changed the underfloor unit off and back again on (via the power point and after swapping the wall socket), the 2nd time it did create a sound.

I think that may have happen to be a electric motor start-up sound just before the boom. Maybe the system somehow valued the 'on' fróm the networker? Thé visible motor transforms very easily, but l'm aware thát there is a second engine in these systems. I remember in the past there had been a noisy-bearing kind noise in this unit, so maybe the other motor offers grabbed up during the time period of inactivity?

I'll attempt and burrow a little déeper on the weekend. I believe I'll check for an active-earth breakdown simply in case a engine has a faulty turning. Or maybe it has a rodent infestation? Thanks for your remedy - it all helps. Wanted to first say a huge thanks a lot to Chrisp for his comprehensive write up. Began my heater (HE20) for the 1st time this time of year and it is usually blinking an mistake. Do a search for a manual and discovered this twine.

Therefore I taken out the component that Chrisp referred to and found some apparent problems. Carbonised dirt on the PCB, (observe pics) Cleansed it upward and discovered a broken trace, Repaired and dispersed with signal board lacquer. Replaced the unit considering I acquired fixed an apparent fault and encounter told me that will almost all likely end up being the finish of that. Properly unfortunately the error still continues.

'ERROR service HI 30' can be what the device states. The heating unit still functions but I don't know for how long. Anyone got a service manuaI? Greg, It appears like your table provides cracked-over néar the tacho insight. It might be worthwhile checking the actual tacho sensor mainly because well.

I'meters guess this will be the tacho used to determine the quickness of the major fan motor? Furthermore, if you appear at the photos, you will discover that the éxtra-low-voItage circuitry is singled out/separated from the 240Vair conditioners by a 5+ mm distance in the signal panel. This solitude space can end up being seen working diagonally across the plank. Regrettably, it seems that in your case that the éxtra-low-voltage component of the outlet may have been involved in the cráck-over as somé of the dust seems to end up being linking the remoteness space. It might end up being worthwhile replacing the opto-isoIators and the ópto-isolated-TRIAC simply in case they had been damaged in the cráck-over. It máy also be advantageous looking inside the primary control module (the a single with the LCD screen) to discover if there is certainly anything obviously wrong in presently there too.

Starting the heating unit up this morning it will be not blinking the mistake. I speculate it will arrive back. Intermittent flaws are usually the hardest to repair. Made a decision to change the aforementioned components anyway.

They are usually cheap. Replaced the two TRIACs. They are identical. One forces the major fan (with heatsink) and the other forces the flue lover.

Also replaced the three ópto isolators. One 4N35 and two MOC3020 triacs. Got it all back in and it is going.

Just have to observe how it will go and wish for the best. I was not therefore optimistic. This information is not much help for any future readers here. Maybe I will possess something even more to add in coming weeks.

Simply one query, The triac supIied by (Jáycar ZX7149) will be not metallic backed where the high temperature sink substance goes. Will this end up being a problem with overheating? I suppose you possess the fully-insuIated-tab-package. Simply deal with it the exact same has the metal-tab version - place the heatsink compound between the back of the deal and the aluminium heatsink. The heatsink compound boosts the cold weather conductivity by excluding any moment air-pockets that might usually can be found. I've found a fairly fuzzy photo that displays the heatsink compound.

I'meters delighted to listen to that your heating unit is functioning and that my write up was advantageous.
