Drayton Wiser 3 channel heating control

[Waitforme]

Hi
I’m trying to install a Drayton Wiser 3 channel controller for my oil fired boiler.
I have separate downstairs / upstairs heating and h/w. I had 2 Siemens room thermostats linked to 2 Siemens rcr10 433 gb receivers which control solenoid valves ( I think ) on the output from the boiler for the upstairs/ downstairs heating.
I’ve installed the Drayton hub with new backplate and mounted the Wiser room thermostats.
How do I get the Wiser room thermostats to control the Siemens RCR10/433 GB receivers and hence the solenoid valves / boiler ?
Or is it not possible to update my system?
Any help will be greatly appreciated.
Thanks.

The Wiser controls the motorised valves, and the valves fire up the boiler. The hub does not connect direct to boiler.

You don’t. The Wiser would take over the whole system and isn’t compatible with the Siemens. Where are the RCR receivers and where have you installed the Wiser?

Thanks for the replies.
The Wiser hub is in my utility room and the two Siemens receivers are in the garage next to the boiler.

If it’s any help here are a couple of photos of my two receivers and the wiring panel below.

So if you’re correct 7, 9 and 10 are wires for heating and hot water, so you need to place the receiver here. I take it you’ve placed the Wiser in place of a previous programmer?

Thankfully the original installer left that note inside the junction box below the two receivers.
I’ve replaced the old controller with the new Wiser 3 channel controller, it’s in the utility room next to the garage which is where the receivers and junction box / boiler are.
I’ve got a feeling that I need to connect the two wires that go to the receivers L1 and LX ( that make the switch to call for heating ) together to normally closed, then I can remove the receivers.
But unless I’m sure then I’ll just reinstall the old set up.
I’m pretty competent but wary and respectful of electrics.

Yep, that’s what you need to do. If there’s an override on the existing receivers, you can try it that way before disconnecting anything

So would that mean connecting terminals 7 & 8 and 1 & 9 in the junction box together ?

I would say so yes
