Corgi programmable unit

[monty9120]

My grandad has the above controller. Heating works if you turn the room stat and the hot water works if you press hot water on the programmer

Problem is even if I set a heating timer whatever we do if we then the room stay up the boiler fires. I'm hoping to get it so the room stats on but only comes on with the programs

The boilers a Worcester Bosch 15ri the system is gravity fed

I have looked through the instructions but for some reason the room stat seems to bypass the programmer even though it's wired in to it

Any ideas

Has it always done this?

If so wrongly wired!

The old controller was ancient. I have followed the corgi website to check for wiring and alls coreect

I have noticed no2 hot water off doesn't have anything connected to it.

It's / like the programmer doesn't cut the switch to the boiler

Here's what's check mine has a 3 port valve

The room stat live number 4 c heating on neutral is boiler switch

Switch is to white on the diverter valve

Pity you never said at first that you have fitted a new programmer and now it does not work.

Many would say call a pro!

It does work just not the programmer for setting timings hot water works when you put it on if you move the room stat central heating works

This is the layout if it. Makes sense exactly as the corgi website says

Your heating system is incorrectly wired. It will need wiring correctly in order to work. I would call someone familiar with heating systems to wire it properly.

The wiring in your hand written list is nothing like that in the Mid-position diagram in http://corgicontrols.co.uk/?ddownload=687

You don't have a gravity fed system with the 15ri, you have a fully pumped mid position system.

can you quote where its different?

Well, there seems to be an extra wire 'live' on the valve, the roomstat call is going to orange on the valve, the cylinder stat cable only has 3 cores and not 4 so there is no hot water off signal....

Thank you any ideas where the grey from the diverter goes then

I'm tempted to change the room stat as I don't think it's wired correctly anyway it's about 30 years old have a new Drayton one here I can test

There is no shortage of diagrams on the internet, as we said you have more than one wiring error, there is no point in changing the room stat if all the other wiring is still wrong, everything on this type of system is some way interlinked.
