Potterton EP2 Twin Channel Programmer

Product Information

Praise the Lord, I had visions of having no hot water and a grumpy wife nagging me to get a whole new boiler for days.

You can make it as simple or as complex as you like in normal user operation, from a simple setting (2 on/offs, every workday/weekend day the same, HW/CH with same time settings) to a complex, highly variable situation as I mentioned above. Gone through the instruction sheet but it is not clear when or how to access just the individual days. Independent or linked refers to the selection of hot water or heating; independent means it’s possible to have the hot water and heating coming on at differing times, linked means both hot water and heating will come on together.The new one has the same contacts into the existing terminals on the backplate - there is also a new backplate provided if you need one, but my old one looked fine so I simply pulled out the battery protection tab, snapped the new programmer back onto the old backplate, switched it on and started programming it according to the instructions. In the initial set up of the programmer, the installer can select a programmer option, based on the wiring and the type of system, pumped or gravity. The Potterton EP2 is a heating system programmer designed and manufactured by Potterton, a well-known brand in the heating and boiler industry.

This programmer meets central heating demands via 24 hour 5/2 day or 7 day time settings allowing the user to select the schedule that suits their weekly or daily requirements.

When slider is moved over to set all seven days appear on the top of the screen and I cannot just get to individual days of the week. They mention that it fits perfectly onto the existing back plate, and it's easy to retrofit into the original mount. Instructions good, but you also need to use the supplied installer instructions to get it working right for you. The extra flexibility doesn't make a lot of difference, because I copied Mondays settings to the rest of the week anyway.

The only thing I found was that the back of the EP2 sticks out more than its predecessors and where I had wiring crossing the central vertical support of the backplate, I could not fully close the programmer onto the backplate. Some mention that it is expensive and bulky, but it works as expected and is a great improvement over the original. Both of these views turned out to be misleading, probably only true of you don't take the time to set it up for your needs, as per installer guide. Took 5 minutes to swap the new EP2 for the older programmer, and 4 of those were spent looking over the installation instructions to check I'd bought the right thing.When setting the on/off times, the screen shows all 5 weekdays at the top of the screen, so cant copy from one day to the next. Hello, I have a existing EP3002 and for some time now the boiler doesn't always shutdown when it's timed to.

If its set lower than the room temp actually is, then the boiler will not come on, or if its one like we had, it may need new batteries.

The Potterton EP2 Programmer can be used for replacing existing older Potterton EP2000, EP2002, EP3002, EP6002 Models using the existing backplates with no rewiring necessary providing the existing backplate is not daMaged and in good condition.I have been using a Potterton EP6000 programmer for some 21 years for my CH system and replaced the 48volt relays when they slowly burnt out over the years, but now the membrane hardly works when pressing the buttons so purchased a new Potterton EP2. I do not have any of these, but the manual mentions EP2000, EP2002, EP3002 and EP6002 so I guess all of those are just as easy to replace with the EP2. As others have said, it’s an easy replacement for an existing Potterton programmer with no wiring or plumbing to worry about, providing your existing backplate is undamaged, which it most likely will be.
