volt free contact inside electric heating boiler

[Kev2632]

Go down to page 8 of this document, you will see it asks for the contacts to fire the boiler up to be volt free, now i do finally understand i think what this means, it means that those two contacts R+P are independently volt free from the power being supplied to boiler, now what i cant understand with the way the booklet is telling you to wire the boiler up is, when wiring a normal 2x 2port valve set up, we supply either the orange or grey with 240 and the micro switch closes sending 240v down the other core, how can this boiler work when there will be no voltage at all applied to either orange or grey cores?? and is it possilbe to feed 240 volts onto one side of the R+P volt free contact at all ? and have 240 come out the side of either R+P ??

thanks again guys

Absolutely!

There you go, done!

Phone the helpline as we are all guessing here and they will have the definitive answer, it will be a lot cheaper than making yourself a very expensive door-stop!

We are not all guessing Strop.
Those of us who have read, and understood the manufacturers diagram have provided the necessary info.

How did you get on mate

Everything went as planned, like you thought above so happy days

 

[stuartcourt]

nice one did you call them and was there a way to get 240 switch live (interested incase it comes up for me)

 

[stuartcourt]

hate it when the last pages of the book are missing wish I had let him blow his boiler up now :donatello: and love the new smileys radical dudes

 

[Silly Sausage]

Had a look at this a few days ago, it says on the previous page (7) do not not put 230v on R & P!!!!!

Is it really that difficult???

 

[stuartcourt]

I wanted to know how he got over it, was there a 230 switch live option or did he have to use contactor but he has done one

 

[FrankUK]

has anyone ever seen a boiler with only volt free connections

Yes I have. It's the 2 wires that connect to the timeclock either inbuilt or external.

(Not required in this case but) yes, there is.

You wire it as the manufacturer states in the installation diagram.

If it requires 240V then it will receive 240V.



Google images - S plan or Y plan wiring diagrams - other methods will probably appear as well.
