Good video Adam. Just a minor one, as you discovered the isolator open during r1/r2 test, assume it was also open during your initial IR test, so internal cable run may not have been in circuit during test.
Cheers mate You are correct, after I re did every test from the beginning in my little order I do it as when I was focusing on filming and trying to test my brain had a fart 🤣
Nice vid Adam. However you should have re-rested your IR readings as you identified that the rotary isolation switch was OFF when you tried to do the R1/R2 tests.
Hey Adam, Nice job 😊, Just one thing i thought of.. would you not have been better doing an end box and conduit down the wall into the top of the isolator instead of fire clipping it down the wall?
Hi adam did you protect the heat pump with a type b rcd? Due to the inverter inside the unit? Also if you read installation manual also says type b rcd?
Hi bud in the installation manual it stippulated about using c type for over load and then type b in certain locations however didn’t list locations it wasn’t the most helpful tbh
Type C MCB for inrush current that loads the capacitors on the inverter board. But as the OP said, you also need this via a type B RCD, that will still operate with the various DC noise leaking back up the supply.
Hi nothing new no as I was just installing a supply with rotary isolation however I did stay around to see how it works / connects up etc But yes normally you need to be MCs acrreddited
Yeah the eBus wiring on Vaillant controls gets upset if run too close to mains or other data buses, using a shielded cable is always a nice touch for trouble free installation
Again it definitely states shielded cable. You need to look at this no type b rcd and no shielded ebus cable. People are paying for this doing correctly
Top job Adam great insight.
Thanks mate
@AdamDunlopElectrical no problem mate. Remember experts on the Internet never know as much as the person onsite 💪
👌🏻
Do these outdoor units require an ethernet internet cable to them or just to the plant room indoor unit then another wire links inside to outside?
nice work Adam
Thanks!

Thanks mate I did do that just didn’t film it check the comment below it explains how I had a brain fart ahah
Yes my apologies I’ve just read that. You’re a star. Be employing someone next to help you. Now, I hear BUNDY doesn’t do much these days 😂😂
Nice one Adam
Thanks

Hi cheers mate and yes that’s a potential way of doing it , might try that on the next one however I never like to do too entry on outside equipment

@@AdamDunlopElectrical RCD mate, not MCB
We fit up to 10 a week. It definitely states type b rcd.
@@damienhanson492910 per week! Some coin being made there
What happens with the bus cable at the other end. Would have been nice to see where the other end is terminated?
Will showcase this more in-depth next month
What's the big hole in the wall for? 🤔
That’s a old oil boiler flue exist I believe
Immigration rules
Was there any extra qualifications you need to do ASHPs? Or just standard sparky bits?
Great video as always lad!

Sounds like more paperwork and fees to ? SOMEONE@@AdamDunlopElectrical
Just a question mate , is that bus cable good for external use, I normally like to run it in flexi con until it’s in the property ?
Yea mate it’s uv rated 👌🏻 , whilst the way it’s ran outside for 1 metere under neath pipe lagging so it isn’t exposed to uv As added extra protection
Potentially I’m there just to install electric suplly / rotary isolator mate
Is that bus cable uv rated mate? Think you should have slipped some flexi con over it
Yes bus cable uv rated mate I believe it was supplied with device
Vailliant dont provide bus cable needs to be shielded also to manufacturers instructions
Manufacturer stated that it should never be twisted or shielded cable for this install
And plumbers supplied it mate not valiant
