Genius required aspa re: Pulsacoil 2000 ongoing problem.

[matt1e]

I doubt the OP has the expertise or test equipment to do those things safely.

he doesn't need test equipment to get a diagnosis of the relay tony, some slight expertise maybe in swapping some wires around

One can understand the problem for those who came during the day to predict it would work at night!

nope. sorry I don't agree, they could had fully diagnosed that unit during the day if they had had a bit of savey in them

I never ask anyone to open up covers on live equipment unless I have a very high expectation that they will be safe. The OP here probably does not even know what a relay loks like!

Two engineers have been and not managed to identify an apparent fault with the off peak heating circuit.

As both are from firms that specialise in Pulsacoil repairs I can only conclude that so called "experts" dont have the "savvy".

Its understandable that the OP has done the best thing possible by calling speciallists and still has not had it repaired. Thats rather sad.

I wouldn't have asked him to work on it live mate but actually, after putting right a simple anticipated roomstat last week that one of our young so called sparkies had done and working with another on a new AHU install.........I kind of take your point Tony

agreed, it is sad
I knew the way I spelt "savvy" didn't look right!

No, I don't have the expertise for that!

Wish I did. Just want the thing sorting!

I will ask the electrician tomorrow to check all the things you said.

Oh, yes - hot water after boost.

Not sure if water the day after the off peak is a result of the off peak or the remains of the boost. Either way it is rubbish.

Hopefully the sparky will tell me if it has power during the off peak or not.

Thanks again for your help, guys.

well if you have a sparky coming
ask him to temporarily swap over the the off and on peak feeds into the unit and check for 230 at the bottom element with the boost switched on
This will check the relay contacts under load conditions

Matt

 

[andrew197]

Ok, I will ask him to do that.

Is there anything else that he should do/check?

the power coming out of the timer when off peak light is on?

yes, if the off peak is on when he is there, then there is no need to "borrow" a supply to test the off peak side of the store

basically both line supplies go into the pulsacoil then to their respective elements via one double pole relay that is permanently energised from the control feed (unless the overheat stat has tripped of course)
that's all he needs to know as far as the heating of the store is concerned any other problems with the off peak supply will be upstream of the unit

Matt

 

[andrew197]

Ok, I can turn the timer to 'think' it is 2am so that it turns on to off peak and the light will come on.. then he can test if it is doing anything?

ah you have a controller, so all your electricity is on a economy tariff then?
yes mate you can do that (as could your other engineers have done)

It will make things a lot easier for your sparky and you can forget my earlier post regarding swapping the supplies

the fault may well be in the controller, but you should get sorted soon enough

Matt

 

[andrew197]

That is the thing - we have an Economy 7 timer thing but out meter is a standard meter so we don't benefit from cheaper electricity OR decent hot water it seems!!

I am praying it is the timer/off peak supply that is not working and I can replace the box on the wall and it will be sorted...

are you sure its a standard meter,it may just look like one to you (a digital led/lcd may only display one line of numbers )
well if that is the case and it is a standard then the problem will lie in either your controller or the pulsacoils internal relay (or the wiring connections)
I would think that the relay will be cheaper to fix than the controller btw

Matt

 

[andrew197]

Yep, I have checked with the supplier twice - definitely a standard meter and standard tariff. It is not even digital. Just the old style thing.

How would that be a problem? Is it not just a case of if the light is on the boiler should be heating water up, regardless of tariff/meter? The boost still works.

Can it be rectified? You said relay? What needs to be done? Or do I buy a new controller? If so, what type?

 

[Breesey]

Do you have a controller similar to this?:

Its not a problem, not to fix anyway
if you have a controller then you will have a common supply which is definitely ok (the supply) as the top heater works
the immersion and stat are supposed to be ok
so the problem lies between the controller and the element
there is only the relay in between
so the problem is the controller ,the relay,or the wiring in between


you dont need the controller if you haven't got an off peak tarriff
do you ever use the boost btw?

Almost - its predecessor it seems.
