Force update of Evohome wifi firmware?

Hi,

Just wondering if anyone else has experienced this and found a solution. I recently purchased the evohome system (including the new wifi controller). Everything's been up and running for about 4 days and working well including remote access to the system over the internet away from home.

However I noticed that the unit is not running the new version of the recently released firmware. I was wondering if there is a way to manually update the unit, or whether it occasionally polls Honeywell for updates and I just need to wait a few more days? If that's the case and anyone knows how frequently this check is done - even better!

Thanks
