Potterton Central Heating Programmer Ep2002 Instructions
I have the above controller. It cannot have the heating and water set to come on at different times so I want to change it out. I have lost the installation guide which has the instructions to open it and the wiring guide - think to open it I have to press a tab on the bottom.
I want to check and see how the system is wired before proceeding. Does anyone have a guide for this controller they could scan and email to me - I have searched everywhere in my house and on the internet. Have only found one locked forum thread. The potterton website is quite poor, no easily available info, I know I could fit an EP3002 on the existing backplate, but I think there are better controllers out there. Looking at the Drayton Tempus 7 or the Horstmann Centaur C27 I am sure both of these would require a new backplate to be fitted from what I have read. Also going to check sizes as fitted to a tiled wall.
Anyone have any opinions on these or advice? Thanks for the reply. Have opened it up to look at the wiring - looks like my one has also been used as a junction box, which surprised me as there is a junction box in the garage beside the pump and boiler. I do remember when the plumber installed it, there were a lot of wires, it took him a long time and then he had to get one of his men back to get it working. Have posted a photo of it here and this is the wiring diag inside the cover I am now off to look at Potterton controllers with the same backplate, if I don't like them I will be calling the plumber to change the controller.
I think the Potterton EP6002 would give me what I want, 3 separate on/off times per day and independent control/timing for central heating and hot water, where the EP3001 gives 2 on/off and water/heating has to be on/off at the same time. Think a new controller would help me reduce my heating bills. What I cannot find is if the EP6002 would go directly onto my existing backplate and work - everything infers it would but very hard to get info online about Pottertom controllers - certainly nothing like the tempus of horstmann controllers.
What Is Central Heating
Can anyone advise? Thanks, I do not have any room stats fitted at all. All the radiators except 2 have thermostatic valves fitted.
There are motorised valves on the heating and water circuits, and a thermostat on the hot water tank. My understanding (very basic) is that when the heating is on the pump runs all the time and the boilers cuts in/out on its own thermostat.
Central Gas Heating Systems
Not sure what happens when the water is on. My existing controller allows each to be on on their own, or both to be on together, with 2 on/off times, the on/off times have to be the same for each system. I am looking for more flexibility from the controller, and hopefully the EP6001 will give me this, I'll find out when I buy it and see the instructions. My system originally had a multi fuel coal boiler, as we did not have mains gas in the village. We had a radiator in the loft that remained on all the time then, I think all the other rads had TRV's, and from memory I think we had a room stat in the hall but cannot remember.
When mains gas became available, around 1992 I think, we had a professional plumber come in, remove the multi fuel and install a gas boiler and fire. The controls have been the same since then, the loft radiator was removed as were the TRV's on the bathroom and shower room rads, and I think the room stat was removed then.
The boiler was moved out to the garage. The hot water tank is in the loft, and the pump is also in the garage. I will ask my mate (he never did the conversion to gas as I did not know him then) about a room stat. I think in all likelihood, as soon as our current boiler develops a fault, we will replace it with a new efficient combi boiler, my current one has a 55% efficiency, and gas bills currently running at £100 per month. I have only started thinking a bit about the heating system as the costs have sky rocketed, and a hot tank does not make a lot of sense, as if the HW is off, as soon as you use some, the temp of the water remaining in the tank must drop as the cold water enters the tank? So really HW should remain on?
