SWOP PL AND LS, DISCONNECT LP,

picasso LP is the permenant live to the boiler mate (had me confused earlier too, thought it was pump live lol)

yea sussed it eventually I thought like any normal person he had connected a permanent live neutral and earth and was just trying to sort out the switching, oh how stupid of me

Matt - We have action boiler fires up for about 5 secounds and the pump is still running but the boiler is not staying on still no lights on the boiler

 

[judger]

I have reset the boiler but still no luck.
I have pressed the heating advance and no luck on that one.
any idea's

right fudger make sure that the pump live is connected to PL
and Ls is connected to number 7 in the wiring centre
remember I told you to swap them out at the boiler end,check that you have not inadvertantly swapped them back at the wiring centre

if everything checks out ok and the boiler is still not working then open the valves manually,disconnect Ls from the boiler and put a link between Ls and Lp, switch on and make sure that the boiler is working

this will tell us if the boiler is at fault or if it is the external controls

Matt - pump live is going to PL
I have not swopped the cables over in the boiler.

I will check if they are not swopped back in he junction box

 

[matt1e]

use your multi meter at the boiler and make sure that you have
230V between Lp and neutral on standby
now turn on the hot water and/or CH make sure that the stats are calling
and check that there is
1) 230V between Lp and neutral
2) 230V between Ls and neutral
3) 230V between PL and neutral
there will be a short delay for step 2 and 3 while the valves open and make the internal microswitch

This is the layout on the junction box

I will try this next:
if everything checks out ok and the boiler is still not working then open the valves manually,disconnect Ls from the boiler and put a link between Ls and Lp, switch on and make sure that the boiler is working

this will tell us if the boiler is at fault or if it is the external controls

 

[judger]

I will try the meter reading first ??

 

[matt1e]

I will try the meter reading first ??

yes

Matt

 

[judger]

This is going to sound stupid.
How do I put it on standby?
and how do i turn the hot water on?

Checked the voltage and it's 246v between LP and N

 

[judger]

Sorry

I don't have a Ps

as you look at the boiler I have Lp...Ls...N...E...E...PL...PN

 

[matt1e]

Sorry

I don't have a Ps

as you look at the boiler I have Lp...Ls...N...E...E...PL...PN

soz I meant Ls

the boiler is on standby when there is no call for heat
you turn the hot water on by selecting hotwater on the programmer {time clock)

Do oyu still want me to do this??
if everything checks out ok and the boiler is still not working then open the valves manually,disconnect Ls from the boiler and put a link between Ls and Lp, switch on and make sure that the boiler is working

this will tell us if the boiler is at fault or if it is the external controls




I have taken a few more pic hope it helps.
