This is the back of the thermostat.

Hi Stem, Which colour are the cables from (2) and (3)? Thanks B

Hi, I installed the Tado wireless receiver, thermostat and internet bridge a few days back (with the help from some of the members on here!). Everything has been working fine- I could control CH and HW both independently from the app. Today I removed the Potterton PR2 programmer and blocked...

Got the Tado receiver wired up and working. Both CH and HW working independently too. Appreciate the support! Regards B

As per - “3 to HW NO (HW on)” 3 from the EP = CH OFF ? So just wondering how you have it going to HW NO as you said it was ON when you have HW On in brackets Should the wiring not be as such- 1 to HW NC (HW Off) 3 to CH NC (CH Off) 4 to CH NO (CH On) Many Thanks B

*CH NC

So I’m guessing that the HW NC connection is for the wired thermostat (PR2) which isn’t needed so I can replace with Tado thermostat..?

OK so 1 to HW NO And how about HW NC as per the Tado instruction?

Prefect. Thanks Guys! I will replace the EP2002 with the Tado wireless Extension. As per the Tado instructions for Y-Plan I think this would be the wiring from the EP to Tado: - L to L - N to N - 1 to HW NO - 3 to CH NO - 4 to CH NC - 5 can be discarded - bridge L to CH COM - bridge CH COM...

Thanks Stem. I’m struggling to get the panel off again, seems like it’s been pried too much and I can’t detach it!

On the EP2002 programmer when switching the CH on, the HW also moves to on. And when you switch the HW off and leave the CH on the boiler switches off. I was hoping to install the Tado kit to allow better control of heating system! I appreciate the time and knowledge!

Thanks Mister Banks. I’m not an expert in plumbing but is it a Y-Plan heating system?

Hi Stem, Thanks for your response! Yeah, there is a 3 port valve in the airing cupboard- how can I test if it’s working fine? I recently had the hot water pump changed for the radiators.

Hi All, I hope someone can give me some guidance on replacing my current thermostat and programmer with Tado. Boiler: Potterton Suprima 40L Programmer: Potterton EP2002 Thermostat: EP2 I have a gravity fed system with tank in attic, hot water cylinder/ radiator pump and shower pump in...
