Plumber struggling with vr66 install vaillant

[aptsys]

you have engineers ( the bunnies ) who know these boilers inside out and you've read there post as a sweeping statement and still try to prove your statement right

I'll eat my hat if you actually know these boilers 'inside out' and can draw the schematic of that PCB. I don't see anything that Bernard said as incorrect about the ebus.

Are you even an engineer?

You had better get your salt and pepper ready then.

Agas is an engineer, and the "bunnies" know their boilers inside out.

Edit
Just in case you are not aware the "bunnies" are Vailliant specialist. They give the experts on the CC, advice and help when we are stuck.

and can draw the schematic of that PCB

That along with the firmware is part of the information needed to fully understand the operation of the boiler. There are various house keeping functions that the PCB performs. Many of these house keeping functions are not mentioned in the information given to installers and service technicians.

firmware = the software programmed at manufacture into the micro-processor

No firmware can be loaded onto a microprocessor. Maybe you mean a microcontroller.

It varies from manufacturer, simpler in this contest to refer to it as a micro processor

Some manufacturers use the micro processor approach with external memory chips

Some manufacturers use the micro controller approach with the processor and memory in the same chip.

The micro processor approach is slightly more expensive to manufacture but allows for easy PCB upgrades by changing the plug in Read Only Memory chip

The micro controller approach is lower cost as there are fewer components on the PCB but upgrades may be impossible on site. In circuit re-programing allows for up-grading, preferable not on site. Some PCBs with lower cost micro-controllers cannot be up graded by in-circuit re-programming and the PCB has to be scrapped if the boiler is to be upgraded..

Up-grading is NOT simply changing various parameters but involves re-writing many hundresa of line of code in the devices memory chip.

You would load the firmware onto the external FLASH or EEPROM if it was a processor based architecture then, not programmed into the microprocessor.

ROM upgrades in that context are a thing of the past.

Give up the pair of you, if it had been installed properly as the manufacturer intended it would never need any of the shoite that you two dream about, it is a heating system that a heating engineer or plumber can buy and install as it was intended to be installed and will work without the things that you **** over

Ok here is the latest. You don't even need a vr66 with the boiler. It has its own 3 port diverter valve which it controls

Christ alive - do you actually read the posts on this thread or are you happy in your own little world?

Ten pages FFS. Not helped by Bernie and his little friend

No way! Are you sure?

 

[mrbg07546]

No way! Are you sure?

Yes.

Ntc to the cylinder from boiler

Vsmart to boiler via ebus.

And no zone valves required.

 

[mrbg07546]

Yes.

Ntc to the cylinder from boiler

Vsmart to boiler via ebus.

And no zone valves required.

And the material for it says "no complex wiring"

 

[The831Bunny]

And the material for it says "no complex wiring"

Who would have thought it! How did your installer come by this revelation?

Well that's news to everyone
