Swap Potterton EP2002 for Honeywell ST9400C?

[Firewood]

Hello,

We are re-doing our kitchen next month and as part of the work we are having some of the wiring around the boiler tied up. I would like to swap the old Potterton EP2002 programmer with a newer type and have chosen the Honeywell ST9400C, as this should allow us to changing timing on the HW and CH independently and has a "holiday mode" for making sure the house is warm when we return from a "summer" UK holiday.

I've tried to find out if this Honeywell will be compatible with by current system before buying but could not find a definitive answer. Can anyone on hear advise before I buy it?

Regards

To judge if the ST9400C would be compatible with your system, you will need to tell us a bit about it cos I can't see your house from here!!
joking aside, I would be suprised if the ST 9400 was not suitable cos it is pretty universal, however depending on your system some of the features would not work - oh and you will have to wire in the new base plate, which is sometimes awkward because the Potterton unit's wiring base has about 4 spare teminals which can be used as a wiring centre, the honeywell base does not have this luxury!

Ahh, sorry, what would you need to know about the system? We can switch off/on the CH and HW independently now with the EP2002, though this has to be done manually via the sliders. The timer switches both on/off together at the moment.

I'm planning to get it installed by an electrician, so they will do any wiring necessary.

Thanks

The ST9400C will be fine!

Unless your spark is very good with heating systems, maybe best to get a heating engineer to change programmers.

Some sparks are hopeless with ch.

Most sparks are hopeless with ch.

Fixed

OK, was being diplomatic.

All sparks are hopeless with ch. (except one I know called Nigel, who lives just outside Weston Super Mare.)

Just thought I would reply to say that the heating engineer I had fixed this find and it's working great.

Thanks
