Hi Guys,

I’m just looking to get some help with wiring the BDR91's and replacing our existing ember EPH controls system.

Basically we have a S Plan System which has a Gas boiler ( Ideal Logic System 24) that requires a permanent live and a stored Hot Water cylinder. There are 2 x 230v Valve’s ( for HW and Heating ).

What would be the best wiring for the above as we will be using the HR92 to control all zones and the hot water kit.

Thanks in advance.

Hi Sean,

S Plan wiring is on Page 46 of the evohome Installation Guide - this is the only way to wire evohome on a gas boiler when keeping S Plan.

Binding an S Plan system is then covered under the customer video section here - https://theevohomeshop.co.uk/forum/view ... ?f=12&t=29

I hope that helps.

Thanks,

Richard

Thanks Richard, all up and running now!

Hi, I have a similar set up to this but I am having problems setting up the central heating side.
I have managed to sort the hot water side but I am struggling with setting up the heating relay box to open the heating valve.
I have turned off the boiler control, and tried re-binding but I seem to have a setting wrong.
The link to the video further up in this post no longer exists.
HELP I am starting to pull my hair out.
Best wishes to all

Well I think I have found the setting I am looking for, having trolled the internet I eventually ended up on the Honeywell site and in one of their support page and found this:-

On the evohome Controller
1 Press and hold SETTINGS for 5 seconds
2 Press the green tick
3 Press SYSTEM DEVICES
4 Press STORED HOT WATER
5 Press ENABLED
6 Press HOT WATER VALVE BINDING or HEATING VALVE BINDING

On the Wireless Relay Box (Hot water and/or Heating valve)
7 Press and hold the button for 15 seconds (until the red LED blinks rapidly) to
clear any previous binding data
8 Press and hold the button again for 5 seconds (until the red LED blinks slowly)

On the evohome Controller
9 Press the bind button
You should receive a SUCCESS message on the evohome Controller and the LED on the Wireless Relay Box should stop blinking and turn OFF. If not, go back and re-bind.

I missed it initially as I thought this area was to deal with the hot water channel, I wasn't expecting to find the central heating under the same area????
Anyhow I am pleased I found this area and I suspect it is what I need........
I hope it helps someone else..........
Good luck everyone
Best wishes

Can I just say many thanks for this. Having spent best part of a day not understanding how to enable heating - this was the fix. What a strange place to put that setting.
