Is it just a matter of switching power off and changing the front panel but leave old EP 3000 back plate on
Yes it is.  A simple swap.

I currently have an EP2001 and want to replace this with an EP2, do I need to knock anything off when replacing the fronts? I am assuming no wiring needs altering.
You will need to switch off the electric before swapping, but other than that is is a simple 5-minute plug-on job with no wiring needed.

Our Potterton EP2 controller has gone blank. Where is the reset button located please?
It is under the flap to the left of the screen.
Does the EP2 have auto time change for BST/GMT ?
No it does not.

Hi,
Ref:- EP2 PROGRAMMER
Please, can you explain to me how to replace the backup battery. I cannot find any instruction in the Installer's Guide.
Many thanks.
Hi
There is a tray on the back of the unit.  You will need a flat screwdriver or similar to pull out the  tray.
Hi,
Bought a EP2 programmer from you earlier today. Please, can you tell me how to override either HW or CH if I needed during the course of the day.
Many thanks.
Hi,
Just press the ADV button and it will come on until the next scheduled time.

Hello, I have a existing EP3002 and for some time now the boiler doesn't always shutdown when it's timed to. Not sure what the problem is but wondered if it's reasonable to think that it's a fault with the programmer so, if I'm going to change it, then to opt for the EP2?
Hi. If turning down the thermostats switches off the boiler, then the issue will be with the programmer. If not, the issue will be elsewhere. The EP2 is the best replacement for the EP3002.
DO I NEEED TO REMOVE EP2 PROGRAMMER TO CHECK IF ITS SET TO FULLY PUMPED, ( AS OPPOSED TO GRAVITY FED) I AM HAVING DIFFICULTY REMOVING IT FROM THE BACKPLATE.
No. It is set electronically.
Hi I have replaced my old programmer for the EP2, however i cant set heating to come on without hot water being on also, and how do i know if my system is pumped or gravity fed. Thank You
Hi It sounds like it has been set up for gravity. If you have 1 or more motorised valves, you should use the pumped setting.
I have an EP2001 which after a power cut has developed a fault. On the central heating side there are no status indicators, Auto, Cont or Off. But on the HW side I do have the above indicators. But we appear to have no HW or CH. There are also now 3 On1, On2 and ON3 with Off1, Off2 and OFF3. Never have I had 3 daytime settings visible (only 2). Is there a simple fix for this ?
It sounds like it has failed and needs replacing.
Hello - on instructions to replace this it says remove battery tab on rear ......I cannot see any tab anywhere.. Can you please advise. Many thanks
Hi. Once you remove the new backplate, it is on the bottom right marked "CR2032".
Hello - I need to replace an old EP3002 switch in my parents house. My dad has dementia so I cant ask anymore. What I am not sure about is whether it is fully pumped or pumped and gravity hot water. There's a pump at side of Baxi back boiler, but theres an immersion heater upstairs and cold tank in loft. If I put the wrong code in for hot water - say gravity and it's in fact pumped, what could potentially happen?
Hi. With gravity systems you cannot have heating on without hot water. When you set the new programmer to gravity, it will automatically bring on the hot water with the heating. There is no harm (except wasted fuel) in setting to gravity when you have a fully pumped system. The easiest way to tell is by seeing if the pump runs (vibrates slightly) when hot water only is running.
hi we have a potterton Suprima HE range with a digital timer 5111963 BP 2000 programmer we need to replace the programmer for an external unit would the Potterton EP2 be suitable
Hi. Yes it would.
I have an EP2 but seem unable to get to the initial setup to change from gravity or fully pumped. I have tried doing a reset without any joy.
Please call support on 0344 871 1545. They will talk you through it.
Hi, I have the old brown EP2000 which works ok, however cannot set different times for CH & HW, if i replace this programmer with the EP2 would that resolve my problem ?, sounds like it is an easy upgrade i can do myself.
Yes, it would. It's a simple swap.
Hi, I have a manual Honeywell thermostat and a EP2001 programmer. My Thermostat clicks when over room temp, but cont mode ch don't fire up the boiler. Hot water on cont does fine. Is there anything I can check on the ep2001 before replacing with an EP2? And is it easy to do your self, ie as its the same back board, or do you have to use a qualified elecy ? Ta
Hi. You really need to check where is receiving power to make sure it is not the motorised valve instead. However replacing items until it works can be cheaper than an electrician. The EP2 will plug on to the existing backplate for an easy swap.
I have an old brown EP2000 programmer and would like to replace it with the most compatible update. I need independent time controls for heating and water. If possible the wiring should also to one for one replacement to minimise the chances for error. Please advise - thanks
This one would be suitable.
Hi - I've recently had a new EP2 replace my old programmer by a fully qualified heating engineer. He set the programmer to provide hot water & central heating at 4am to 6am and then 4pm to 6pm on Monday to Friday but was UNABLE to alter this for the weekend !!I have tried numerous times to rectify this including the re-set button with no joy. The timer will NOT travel past 05.15am or go back beyond 12.15am please help
Hi. Please call support on 0344 871 1545 and they will talk you through it.
Hi I have looked though the questions re changing an old EP2001 for the EP2 and it seems lots of people have done this. i purchased an EP2 from you and find that in the instructions there are codes to allow replacement of EP2000 and EP2002 but I cannot see anywhere which setup code I should use for the EP2001. Are you able to help me? Regards, Mark
Hi The reference to the old models is just to show the functionality those models had. You can choose whichever functionality suits your needs. Which model you are replacing is irrelevant.
Hello, I am not a heating engineer. I have a an EP2001 which after a power cut has developed a fault. On the central heating side there are no status indicators, Auto, Cont or Off. However on the HW side these indicators still work (except the HW red indicator no longer illuminates) and if I cycle through the HW mode selection the CH illuminates! but no indication of what mode Auto, Cont or Off. Is this simply a fault on the EP2001 or could it be an indication of another problem? If this is a faulty EP2001 then I will replace it with an EP2. Regards, Mark
Hi All you can do is reset the unit to try and rectify the fault. If no joy, then you will need to replace it.
Hi, I have an existing EP3001 controlling heating and hot water via motorised valves. Can I replace this with a more controllable unit that has power back up. Fed up with resetting unit after power cuts. Can you recommend an easy replacement please, thanks
Hi. Yes, this EP2 will do that.
I currently have a potterton ep2002. At the moment I am unable to select different times for the heating/water. Will this EP2 allow me to set different times for the heating/water??
Yes it will. You will need at least one motorised valve on your system to be able to have heating on without the hot water.
Will it directly replace my older Myson MEP2?
A backplate change will be needed. The MEP2c is available on our website.
Just had potterton ep2 programmer installed but tennant changed times , how to get the preset back to work. Please
Please see the instructions under the 'Downloads' tab.
I bought a Potterton EP2 programmer in March last year. The central heating comes on irregularly throughout the day (usually once but sometimes twice) when the central heating timer is off. I've checked whether the boiler has a frost thermostat and it doesn't. Can you offer any explanation as to why this is happening?
Turn both the thermostat down and see if it still if it still happens. Check if the hot water is on.
How to change configuration of my new Potterton EP2 from 5day/weekend to 7day 3 on/offs please
You will need to do a factory reset to get the options back up. Please call support on 0344 871 1545
I carried out a straight swap new for old with a Potterton EP2 Programmer from your good selves hoping I would be able to programme HW and CH separately, but couldn’t. It only works with HW and CH running together. Are you able to email me a wiring diagram which will enable me to change what I am guessing is a faulty setup?
There are several different wiring diagrams depending on what motorised valves you have. (S-Plan Y-Plan, C-Plan) Make sure you choose a programming mode with independent timebases when setting up the programmer.
I Have an old potterton ep2001 will the new EP2 be a straight swap unsure as I have looked at the instruction notes online and it doesn't mention the 2001 ?
Yes it is.
Looking at the installation guide when setting up operation it states refer to table for correct operation choice the table only calls out the old potterton 6002,3002,2002,2000 units. What do you select if you are replacing an ep3000 with this controller unit. I will be using the existing backplate
If you have 1 or more motorised valves use ID 1-6 depending on how many on/offs and daily programming requirements you have. If you do not have any motorised valves, use 7-12 depending on how many on/offs and daily programming requirements you have. The referal to model numbers in the table just shows the capabilities of older models.
Does this EP2 Have a back up battery, and does it have a back light. Regards.
Yes, it has a backup battery and a backlight.
I’ve just moved into a new place with a potterton EP2 programmer on the wall. When I turn the hot water on it doesn’t work unless I also turn on the central heating. Is there not a way to just turn on the hot water without having to also turn on the heating? Thanks
You should be able to have hot water only on. If it is not working then you may have a failed motorised valve.
What is the model of the backup battery for EP2?
It uses a ordinary CR2032 battery.
I have a EP6000 programmer that has failed. Will the EP2 plug into the existing wired back box without any alterations ? Norman
Yes it will.
Would this controller be suitable for our village hall. We have two zones and need different times on different days, so the usual 5/2 system isn’t sufficient.
It controls one heating zone and one hot water zone. You can have different times for each day of the week.
Hello there, I have Potterton EP2 timer that appears unable to keep an accurate clock time. After a few weeks, it starts to lose time. This morning, it was 7 mins slow although was only reset a few weeks ago. Is this a common fault? Am I missing something obvious that I should be doing? Thanks Rachel
Hi. No, it does sound like it needs to be replaced.
Hi I have a old potterton ep2002 it's a brown/cream colour was wondering if it's a direct replacement with the ep2 would I have to change the backing plate and any wires
Hi. No, it will plug straight on for a very simple swap.
I have a EP3002 controlling a system with a hot water tank, pump and 3-way valve. If I manually turn the Hot water on, then manually setting the Heating on has no effect even though the Heating LED on the controller comes on. I have to switch the Hot water off, before I can turn the Heating on manually. and it's the same if I do it the other way around. The Heating being manually on stops the Hot water being switched on manually. I can only switch both on at the same time using a programme. Will a new controller like the EP2 fix this?
It is very strange that it is working on timed, but not on the over-ride. I could not confirm a fault without checking the outputs to see if the programmer is outputting a live.
I currently have a faulty EP3000 can I replace with EP2, My system is gravity fed will I be able to have independent Heating and Hot Water
Yes, it will be a straight simple swap.
Hi just moved in to new house, and I have a old ep3000 timer. It allows me to set the water to twice. but not the heating. If I change to a new ep2 will this do the job, and can I do it myself
Yes it will. Its a simple job.
Hi, Thanks for answering my last question. I am currently reading an online installation manual and looked at other questions, and now have another question. It states that at first power on, you need to choose Fully Pumped or Gravity System - firstly, how do you determine that, and secondly if were to get it wrong, can I then choose the other option. Thanks
If you have one or more motorised valves, then you need to choose fully pumped. It can be changed if you get it wrong.
Hi, I have a Potterton EP2002 with a Honeywell FrostStat alongside and wired in, but no other room stat anywhere in the house (almost all the rads have stats on). I have independent control of HW and CH via the sliders, but not via the timer (all on or none - provided sliders are both set to timed - I have two timers and can differentiate weekday vs weekend) If I replace with an EP2, will I then have independent timed control of both CH and HW and other than that, will things continue to operate as today. Boiler is an oil fired Worcester Danesmoor 20/25. Thanks.
Hi Yes, you will be able to have different times for heating and hot water without changing anything else.
I have just replaced my faulty EP2 with a new one, but the additional instructions when configuring the programmer didn't indicate what No. to input for 3 on/off settings and either pumped or gravity systems. Perhaps I can revert to factory settings and re-configure if you can let me know what no. I need to input.
Give technical support a call on 0344 871 1545. They will talk you through it.
Hi I have an oil fired boiler and a very old system with an EP2001 programer and can't set the programmes independently for the CH and HW. Will the EP2 do this okay?
Hi. Yes it will. Just set it to gravity mode on installation.
How do you open the EP2 Programmer to replace the battery?
There are tabs underneath that you use a flat-headed screwdriver to push in. It then hinges up. Remember to switch off the power first.
Is the potterton EP2 a direct replacement for the EP2000 and is it possible to replace directly, I am a keen DIY enthusiast, is it something I could replace?
Yes, it is a simple job.
Every time we have a power cut my 2002 loses its programmes do I have to replace a battery and if so how do I do that?
If i is the earlier one with the removable battery, then you can change the battery in the back of the unit. If not, you will have to replace the programmer with the EP2.
Am replacing an ep2002 with an ep2. The chart at section 11 of the instructions implies that if you previously had an ep2002 then you press ID number 7 when setting up. However I want 'independent' HW and CH timings and 3 on/off periods. What ID number do I imput?
It would be either number 5 or 6 depending on whether you wanted 7-day or 24-hour control.
WE have a Potterton 6002 and the switch on the CH is loose now we can't get the hot water to come on but although the CH is off and thermometer is set at 0 the heating comes on when the water should be on (timer set times). Would the EP2 replace this model and can we do it ourselves easily or do we require a plumber? Thank you for your help
Yes, the EP2 will direct replace the EP6002, it is a simple DIY swap. However, it sounds like a motorised valve problem you have.
I have a potterton EP2002 fitted. It's time for a change as the sliders are getting faulty. Is the EP2 my only option? Is there a suitable WIFI timer that would be an easy fit? Thank you in advance. Barry
The EP2 is the only one that will fit onto the existing backplate. If you want a WiFi one, you will need to change the backplate.
Will a Potterton EP2 Programmer fit the backplate of an old Potterton Mini Minder E?
I'm afraid not.
You state that the clock maintains the programe in event of a power cut. Is the battery built in or do you have to order it separately?
It comes with the programmer.
I currently have an ep2002. However it does not enable me to, for example, set CH from 6am one day until 2am the following day. It will only go to 11.50pm the same day. Does the ep2 enable one to go beyond midnight or does it have sufficient timer options to get around this eg 6am to 11.50pm them 12.01am to 2am (at the same time being totally independent from the HW options)
No, You cannot programme past midnight. You can have up to 3 on periods per day per channel (heating or hot water).
My potterton EP2000 timer needs replacing, is this something that I would be able to do or do I need a plumber ? Thank you Carol
Its a simple DIY job.
I have an EP2002 and would like to have hot water and heating to come on at separate times. Can you please confirm if this is compatible with the Megaflow unvented mains pressure water heater system?
Yes it is.
will the EP2 backplate fit old EP3000
Yes.
Does the EP2 fit onto the EP3002 back plate (BP01, the back plate used as a wiring centre) ?
Yes it does.
will the ep2 fit straight away in to my old existing ep2000 with thanks.
Yes it will
Hi Is the EP2 a direct replacement for the EP6000 ie will it plug straight into the existing EP6000 backplate which is wired for fully pumped? Also does the EP2 have a replaceable back up battery? Thanks Robert
Yes it will. Yes it has a replaceable backup battery.
Hi, does this model have a replaceable battery?
Yes it does.
Hi, I have an EP6002. After a power cut the programmer doesn't seem to have retained my programmed times, it appears to revert to some factory set ones i.e. on at 6.30am off at 9.30am. Is it the back up battery that has gone, in which case can you get a replacement? Or is it simpler to purchase an EP2 and if so, is it simple to fit? Thanks Harriet
I'm afraid the battery in the EP6002 is not replaceable. So a new unit is required.
When I select the CH/HW switches to on my Potterton ep3000 "chatters" for about 10secs before the boier fires up - does this sound terminal or fixable?
It sounds like it is on its way out.
I look after the heating in a church hall which has a Ideal Concord CX boiler and a EP3000 programmer...I think the programmer is faulty...will a EP2 be an easy swap and would it be something perhaps I could do (not much wiring experience) ?
Yes it will plug onto the existing backplate for an easy swap. No wiring to do at all.
How can I tell whether I have pumped or gravity system ? My ep2 is set to gravity.How do I change it to Pumped ?
If you have 2 x 2-Port or 3 x 3-Port motorised valves then you have a fully pumped system. You will need to reset the programmer and follow the installation instructions to change it.
I'm looking to replace my EP2002 and just want to be sure that this new EP2 will replace it and will give me the ability to set different on/off timers for the hot water and the central heating? So how many timers can I set to control the hot water? And how many different separate timers can I set for the central heating?
Yes, it will clip onto your existing backplate for an easy swap. You will need 1 or more motorised valves on your system for completely independent heating and hot water. You can have up to 3 on periods for heating, and up to 3 on periods for hot water.
I have a potterton mf100 boiler fitted with a bp2000 which controls heating and hot water and it is faulty can I simply unplug and plug in an ep2 controller for hot water and heating
The EP2 goes on the wall next to the timer. You will need to get a heating engineer to link it up to replace your built-in BP2000 programmer.
From what I've read replacing my existing EP3001 with an EP2, in order to give me separately controllable water and heating, should be as simple as isolating the electricity, removing the EP3001 frontplate and wiring in the replacement. Is there really nothing else I need to be aware of?
Yes, in fact you will not need to do any wiring as the EP2 simply plugs on the existing backplate. But you will need one or more motorised valves for completely independent heating and hot water.
I have a ep2002 with an unvented pumped system with separate valves for the heating and hot water. The existing valve does not allow separate control of the hot water and central heating. Will the ep2 give separate control and is it a diy replacement?
Yes it will. Yes it is a simple replacement as it will plug onto the existing backplate for a simple swap.
I have an EP 6000 programmer which is now 25 years old and has performed with out fault. I have only replaced the battery once. The screen information is now beginning to break up. Is the EP2 a direct replacement ie can I use the existing back plate?
Yes, the EP2 will plug onto the exiting backplate for an easy swap.
I have a MODEL 2002 and would like to be able to have the hot water and heating to come on at separate times. My system has motorised valves and is pumped. Can I just fit the EP2 to the back plate.
Yes you can.
we have EP 3002, we can not programme the hot and central heating to come on at different time. I am looking to replace it with EP2 as I understand it has the same back plate. Will I be able programme the central heating and the hot water independently. ( dual channel I believe)with this programmer. please advise.
Yes, you have the option to programme them independently. However, you will need a fully pumped system with one or more motorised valves to have the heating on without the hot water.
I have a EP3000 which I would like to update with the EP2. Is the EP2 directly interchangeable with the EP3000? The EP3000 provide a pump "run on" after the boiler has shut down. Does the EP2 have this facility?
Yes it is directly interchangeable. The pump over-run is controlled by the boiler so will still be maintained.
Hello, We have an EP2001 which is recieving power from the mains (as it has a backlight) but there is no wording on the display (i.e. we cant see options for turning on CH or HW) and therefore we cant turn the boiler on. I am thinking that the programmer is at fault, is it safe for us to buy an EP2 programmer and fit this ourselves? Thanks in advance for your help, Laura
Yes it is quite simple to fit. You just swich off the electric, then unplug the old programmer, plug on the new one, and switch the electric back on.
Can you programme this for different times each day of the week? Thanks.
Yes you can
I'm looking to replace my Potterton EP3001 with this EP2 programmer. Is it straight forward to replace myself, or would I need an electrician to fit it? I don't know anything about electrics. Thanks.
Its quite simple to do. You just switch off the electric, unplug the old programmer, and plug in the new one. You can then switch the electric back on and set the programmer up. It should take around 10 minutes to do, and full instructions are included.
The display on my Potterton EP6000 programmer has gone blank. The battery is almost dead (less than 1volt). Is the fault likely to be the battery or the programmer itself? OR should I cut my losses and replace the current EP 6000 with a new EP2
The battery only comes into operation during a power cut, so if the unit is receiving mains power then it will be the programmer at fault.
can the ep2 be set to come on three times a day rather than two,if so then how.
Yes it can, you can select it through set up.
Hi I have a potterton 2001 HW/CH programmer with a battery that's is not able to be charged and can only control either the CH /HW .separately .Will a new battery solve the problem or will I need a new programmer. Thanks.
A new battery will not solve the problem of the separate heating/hot water. So I would recommend changing the complete unit.
Hi, We have a EP2002 with combined timing for heating and water, if we replace it with EP2 will it give us separate timing for each? Thanks
Yes, but if you have a gravity system then it will still bring on your hot water when your heating is timed to come on. This is because of a limitation in gravity systems.
Can you tell me if this unit has the British gas standard backplate please? Thanks
No it has the EP backplate.
I want to re place ep2001 programmer will ep2 do the job
Yes it will.
I have an old brown coloured Potterton ep2000 programmer which is unreliable. Is the backplate of the newer EP2 identical in template and wiring order to my old one ? Also, could I keep the existing brown backplate with its present wiring,and just connect the front end of the newer EP2? As mine is set to 16 programmes, is there a switch in the EP2 for the same? Thank you for taking the trouble to answer my questions. Best Regards, Peter.
Yes it will just plug on your existing backplate with no wire changes. Yes there is an option for fully pumped or gravity systems.
i want to directly replace potterton EP2002 WITH SAME FITTINGS WILL THIS DO THE JOB?
Yes it will.
Hello I am thinking of up grading my EP3002 programmer with the EP2, can you confirm that I will have the full functionality of the EP2 (individual timers for HW and CH, and be able to use 3 on/off times for both) when retaining the back plate.
Provided your system supports it.
Does this product have a battery and if so how long does it last before it needs to be replaced.
Yes it uses a standard CR3032 battery. It should outlast the unit during normal use, but can be replaced if it doesn't.
