Confusion and control problems with Secure thermostat and boiler control

I have a bit of an issue here. Last year, before I began building a Z-Wave network I installed a Secure SCS317 Programmable Thermostat and Secure Boiler Receiver. I paired them together at the time and they worked just fine, no problems at all.

Now I have started building my network I thought it time to bring them into the fold, so I included them both in UI7, the Thermostat appears correctly, shows battery level, room temperature etc. The Boiler also appears as 3 items, 1 parent and 2 child (as expected according to Vesternet application notes). i can get the boiler to fire up and switch off manually BUT I cannot get the thermostat to control the boiler independently. I have made an association (Group 2) for the SC317 and added the Boiler but it doesn’t appear to work. I’m not sure what I’ve done wrong, and I’d really appreciate any help you guys can offer.

Thanks.

I just set up 2 of these stats and they are working well to get the stat to associate with the relay outside of vera put stat in associate by dip sw 1 on and get A on display then press wheel A flashes then press zwave button on relay and A should change to AP and it should work

As an aside can I ask you how you find battery life on the stats what have you your wake up and poll set at
