Ivt air x 50 ashp ebay bargain or .... not

[Jacob]

Hi all, long term bhf stalker here , been self building a house for sooo long,  its now an embarrassment.  Made lots of errors along the way and the latest by purchasing an ashp from eBay. Its a new ivt airx 50, 5 kw,   I think bosch bought ivt and now their branded as bosch, they are still sold as buderus as well in Europe . Would be a bargain but the thing is it came without a controller, usually found in the internal split system part called 'airbox '. That would have the rego 2000 controller in it and a pump ect but all these products became discontinued last year

by UK distributors alto energy. 

I have tried emailing around with no luck to find a controller and looked at some aftermarket ones on aliexpress. 

Seem a shame not use the ashp as the quality looks great, the specs competitive and it was very cheap. 

 

Any ideas what I can use to control it , 

Ideally with cooling option ? 

I'll put some pics of the connections for reference as would be great to see one of my rash purchases paying off with some help !

Can you post as much information as you have e.g circuit diagrams, instruction manuals or links to them?

IVT uses 0/24v normally on the control pins. Got a better close up of the control connection points on it ..

These are CANBUS controlled - so unless you can find a controller then it’s not a quick fix

Thanks for looking Peter,  I saw some electrical  forum that was offering diagrams to make a controller for this model but thats beyond my skill by a long way.

Thanks for finding them, they sell the controller and box that signals it aswell, twice what I paid for the ashp but all in will be ok . Don't know how I didn't find them before, doh!  

Wow the price of parts for this brand..... compressor £1200 ...eek 

[ProDave]

Yes it must hurt when something like that costs so much.  My pet gripe is if you need a new PCB for a boiler, something that looking at it and with the components it has would cost about £10 if you were buying it to fit in a television, has a silly price tag.

And it's nearly always just the filter capacitor that needs replacing on the switch-mode PSU - a part that you can buy for 50p

Ah, so you bought that one then….. good luck. It was in my watch list
