Any problems you lot have had with pump & boiler running on all the while,

My problem is if I turn the heating on the boiler fires and pump runs.
However the room stat is an analog type and I disconnected the receiver unit.
Boiler still fires up but Y Valve does not motor.

Am thinking a back feed through the wiring centre it's the " Pcb type with link"

So just to be clear ch on on clock power to room stat common nothing on switch wire from room stat because I removed the receiver unit, no power on white wire. But I do have power on the orange wire :/

Possibly the programmer putting voltage out mind on htw on when I call for htg?

Your stabs in the dark are welcome?

If you are using a "HONEYWELL" PCB wiring centre, there are several links some of which need to be cut, one of the links is remote from the others and is the Timeclock Vs Full programmer link, this must be Cut otherwise symptoms you describe will be experienced

It's been in for 4 years lol ! Do you know way number link boilerman2

If it's a twin channel programmer do you cut the link mate?

For Y plan cut L4 and L5, and cut L6 if you have pump overrun.
Instructions are inside the lid.

If you have pump overrun stat on the boiler, that could be sticking on?(Profiles were good at that)

Good to see you back Chris

been a while.

Those wiring centres (note NOT Junction Boxes) are horrid.

I have had to take a few out where all sorts of weird things were going on even with the right links cut.

Out of interest... is the boiler you have connected a Wooshitter Botch?

ChrisR · 7 Aug 2014

But I do have power on the orange wire :/

What voltage are you reading, while it's connected to the boiler.
Not about 100 Volts AC by any chance?

Thanks Steel. I don't log in much now. Mostly the same old silly *****s here. Some of the silly *****s gone though..

Dan Robinson · 7 Aug 2014

Lots of silly sh|ts here Chris... but there are lots of gooduns as well.

You shouldn't be a stranger.

Ideal Icos dan items a eaga install. Am going to cut link 1 the programmer one, if than does not work am. Going to re wire the dam thing in to a a normal 10 way box.

Boilerman2 · 8 Aug 2014

How did you get on after the Timeswich?prog link was cut (L1??)

Alex10 · 8 Aug 2014

Going back mate on Tuesday armed with 3 hrs to re wire system and on wire snips to cut link

Alex10 · 8 Aug 2014

Or Re wire! Hoping this link will work ! Why does it make a difference if it's a twin channel digital programmer over a mechanical timer??

Boilerman2 · 10 Aug 2014

A time clock is a single channel unit so the link is there to ensure that both hot water and heating operate on the time switch, as a programmer is 2 channel, the link has to be cut so that each channel only operates it's dedicated duty

Lovely! I did notice on my first visit this was not cut so I'll cut it!

Thanks mate

Alex10 · 14 Aug 2014
