Gary the gadget guy'day, have a Brivis HE30 central heating, the one with the Networker panel. It functions great - have got got it for simply over 3 decades now. About 5 a few months ago where we experienced to possess Brivis out under guarantee to substitute a 'sticking' thermostat that produced the unit think it has been getting extreme over-temp inside the unit (common problem apparently). He also observed that the unit has been 'cycling', usually heading over-temp internally then changing off the gasoline putting enthusiast on 'highest speed' to clean it, and that would spiral around every several a few minutes. He set that by changing the pc to a better fan-speed só it didn't cycle so much.

Today that the unit is simply outside of its warranty, wouldn'capital t you understand it, there is certainly another issue. Some ducting opened up under the house, so minimal warmth, but simple enough to fix.

(use more duct record). That it opened up/split was possibly due to a amount of stuff, plumber/myself moving over/under/manhandIing some of thé ducting under thé house while carrying out graywater cable connections. Where it opened up has been in the major duct out from the device, about 2 metres from the device, where another temp sensor goes 'into' the duct. I recorded it all back again upward, but since after that there will be a little spanner displaying on the Networker panel, although the device is otherwise working good, generating great high temperature, all the sleep. Since its out of warranty, i'd rather not have another service callout fee (100s of $$) for what can be likely a problem i've already cleaned by re-áttaching the ductwork. l wear't suppose anyone right here offers the Brivis He or she30 service manual from the 'dealer' section of that they'n be prepared to posting?

Ok, obtained a stage further right here. The device DOES give me an mistake amount, its mistake # 31 on L01. Since this isn't in any manual i actually have, i known as Brivis, they inform me thát its the AFR0 sensor which is usually a safety issue that evidently detects 'fire in the return outlet'. If its attempting to set open fire to the ductwork. Its not really regarded a 'critical problem' and as such doesn't prevent the unit from operating.

Error #31 specifically means that it has long gone open-circuit ón the sensor, só its burned up or disconnected in some way. Through my google-fu skills, i present which will point out the 'AFRO sensor'.

I furthermore found a TradeLink parts list which has the sensor shown on web page 162. Would nevertheless enjoy to possess a duplicate of the service guide if anyone here offers it.

Does anyone possess any experience with restoring a Brivis main heating device? A little bit of history: A while back again I got difficulty with a electric circuit periodically stumbling the outlet breaker.

I initially supposed that I had a faulty appliance so I do an insulation break down test on all the devices. All of them examined out okay except for the central heating unit that demonstrated a little little bit of leakage. I left the central heating unit unplugged, but the tripping remained. The tripping fault was eventually discovered to be a animal chewed cable connection. This has been fixed by an electrician.

In the procedure, the power wall socket to the main heating unit (installed by the heating system installer) was wired with the active and natural transposed. This had been set up as well. The issue: The main heating device has been recently still left unplugged for several months now, but I believed I should plug it in in planning for when it can be next needed. At 1st, nothing occurred when I connected it in (ánd l didn't anticipate anything to take place). Nevertheless, when I examined the controller inside, the display screen was still blank. I thought that probably I connected it in but experienced did not remember to change it on? I proceeded to go under the home once again to verify.

It has been on, so I believed I'd test the various other outlet (its a double shop) just in situation. When I connected it in to the other store and changed on - something unforeseen occurred. It went Hammer! And there had been a display near the right-hand aspect vent out (the one nearest the 'superstar' label). I transformed everything off and taken out the cover up to appear for any obvious troubles. The nearest I can inform, is definitely that the flash may possess been near the blowing apparatus engine.

The engine rotates extremely freely so I'm not really convinced it will be the motor. Furthermore, l didn't reaIise it at thé time, but the signal breaker tripped as well. Will anyone have any concepts or ideas as to what might be incorrect? I'll probably possess to wait around until the weekend before I have time to appear further. Any guidance and assistance would end up being much appreciated. I possess a Brivis HE30 here.

From storage when you bring back mains power nothing at all occurs until you strike 'power' on the Networker cell. Nothing shows up on thé LCD inside thé device itself. One point that does look a little bit odd is definitely that to my thoughts your device is definitely on its part. At minimum for a HE30, its all best accessible, not really side-accessible. lf thats the situation maybe having switched on strength while its on its part is usually an issue? As far as what 'blew', its not most likely to be the engine as it would not really have vitalized the electric motor as yet, it just does that when it is definitely transformed 'on'.

From memory space there will be a blend for the inner controller, probably notice if you can find that. Also follow the mains wiring and find where that will go. Maybe something is definitely open that should not be? Simply because considerably as what 'blew', its not most likely to end up being the electric motor as it would not have energized the motor as however, it only will that when it is certainly switched 'on'.

I'michael a little puzzled by that too. The very first period I changed it on, nothing happened at all (which is certainly regular). When I proceeded to go inside to check the 'networker' it was still completely empty (no time, no smooth key selections). I did strike the energy key on the nétworker but it didn't appear to create any distinction. However, when I changed the underfloor device away from and back again on (via the power point and after swapping the wall plug), the 2nd period it do create a sound. I think that may have become a engine start-up sound just before the bang. Probably the program somehow appreciated the 'on' fróm the networker?

Thé visible motor turns very effortlessly, but l'm aware thát there is a second electric motor in these systems. I remember in the history there has been a noisy-bearing kind noise in this unit, so probably the additional motor has grabbed up during the time period of inactivity? I'll try out and burrow a little déeper on the weekend break. I believe I'll check for an active-earth break down just in case a electric motor has a faulty winding. Or maybe it provides a rodent infestation?

Thanks a lot for your answer back - it all helps. Needed to very first say a huge thanks to Chrisp for his detailed write upward. Started my heater (HE20) for the first time this period and it is blinking an mistake. Did a lookup for a manual and discovered this thread. Therefore I eliminated the component that Chrisp described and discovered some obvious issues. Carbonised dust on the PCB, (find pics) Washed it up and found a damaged track, Repaired and sprayed with routine panel lacquer. Replaced the unit thinking I had set an obvious problem and expertise told me that will most likely end up being the end of that.

Well unfortunately the mistake still persists. 'ERROR service HI 30' is definitely what the device says. The heater still works but I don't understand for how long.

Anyone obtained a service manuaI? Greg, It appears like your plank has cracked-over néar the tacho insight. It might end up being worthwhile looking at the real tacho sensor as well.

I'michael think this can be the tacho utilized to figure out the quickness of the main fan electric motor? Furthermore, if you appear at the photos, you will notice that the éxtra-low-voItage circuitry is definitely separated/separated from the 240Vair cooling by a 5+ mm gap in the signal panel. This solitude gap can be seen working diagonally across the board. However, it seems that in your situation that the éxtra-low-voltage part of the circuit may have been included in the cráck-over as somé of the dirt seems to end up being bridging the solitude space.

It might be worthwhile replacing the opto-isoIators and the ópto-isolated-TRIAC just in case they were broken in the cráck-over. It máy furthermore be advantageous searching inside the major control module (the one with the LCD screen) to discover if there is definitely anything obviously amiss in generally there too. Beginning the heating unit up this morning hours it is usually not flashing the error. I think it will come back.

Intermittent problems are usually the hardest to fix. Decided to replace the aforementioned components anyhow. They are cheap. Replaced the two TRIACs. They are similar. One pushes the main fan (with heatsink) and the various other memory sticks the flue lover.

Also changed the three ópto isolators. One 4N35 and two MOC3020 triacs.

Obtained it all back again in and it is usually going. Simply possess to notice how it goes and wish for the best. I am not so optimistic. This info is not much assist for any long term readers here. Probably I will have got something even more to add in arriving weeks.

Just one query, The triac supIied by (Jáycar ZX7149) will be not steel supported where the temperature sink compound will go. Will this be a problem with overheating? I believe you possess the fully-insuIated-tab-package. Just treat it the exact same provides the metal-tab edition - location the heatsink substance between the back again of the package and the aluminium heatsink. The heatsink substance increases the cold weather conductivity by removing from the total any moment air-pockets that might normally exist. I've found a considerably fuzzy photo that displays the heatsink substance. I'meters delighted to hear that your heater is operating and that my create up was advantageous.
