No probs.
I suspected it was aimed at the thread author

tony keeps moving the goalposts while wearing blinkers and blames others of not understanding the game plan.

This happens on a regular basis DP..........there was a post in here not long ago about faulty thermistors , someone suggested to leave the possible faulty thermistor in situ and just swap the plug connector over to replacement thermistor...Agile referred to this as being a 'parts changer'......funny thing was he gave this 'part changer' advice a week later in the closed part of this forum....

I know Adam.
A man travelling on a bus to do repairs is Beano and Dandy idea
I have a van with good stock of spares and I still run out for a bit here a bit there. Mind cannot comprehend
Then comes requirement for precision when others are concerned while for self it a a broad brush

Why give advise if you are not sure. Not our man frae auntie- dives in head first and the prevaricates

One could accept the shortcomings but when he starts slagging people I know, well that is the last straw

He 'told me off' for advising one poster to send me a PM so I could help, yet it is ok for him

 

[Steelmasons]

He's a charlatan DP.

I give advice on the forum.

Never ask them to PM me to give them private advice.

Part of the fun of a forum is to read what others are saying.

Bernard, when describing a boiler operation, its normal ( and indeed common sense ) that the boiler is described with everything in it working correctly!

When I worked in Doha, Qatar, I had a "staff" from Pakistan who had little or no experience of electronic equipment. They were recruited because they were cheap! So for their training I would "put faults" on equipment and let them try to find them. But to be kind to them only one at a time!

Well gentlemen I have far more experience of this boiler than either of you will ever have as I worked with Alpha R&D and you can smoke screen all you want and play at being pretend engineers but the simple fact is when the switch is removed that causes a call for heat from the boiler and the diverter valve will still be in the CH position so the heat goes to the radiators, the switch was not wired up the wrong way at the factory, that is how it was designed, you can use any fancy words you like to try and cover the fact that you havent a clue what you are talking about

Adam, are you sure re closed part of the forum? You are not having a senior moment are you?

Perhaps coffee you spat on the keyboard is writing the messages for you

corect steel it was me that advised using a replacement thermistor as a test,as it was a vokera and that is mostly what I work on or Alphas its the same thermistor ( yes there are all different colours etc but its a simple test) I always have one in my work trouser pocket and his majesty called me a parts changer then had the cheek to advise someone else as if it was his idea

 

[bernardgreen]

but the simple fact is when the switch is removed that causes a call for heat from the boiler

Removed or falls off due to an un-lucky horse shoe.

Not seen one come off on its own accord. Possible, but I have not encountered one

not possible to be pushed off as when the diverter valve diaphragm actuates the shaft there is a part of the shaft that has been machined out and that allows the horse shoe switch to extend and sends a signal to the boiler to fire, exactly the same as what happens when you pull the switch off and anyone who has removed one will know they arent the easiest of things to remove so would never fall off

Ian, you are missing the point!

When the switch is removed it initiates a DHW demand condition.

Where the heat goes, depends on the position of the diverter valve.

At rest, the heat goes to the rads.

If a tap is turned on, the diverter valve moves and the heat goes to the DHW.

I appreciate that Dan is the one with an English degree but surely others can understand simple English?

Have my Steel helmet. Am going to my underground shelter. Have run CAT5 cable for tinternt. Will watch the missile play on the computer from a safe distance. Can see Ian will be defcon5 when he reads this
