Does pressing the button also restart the 'sync' process if sync has been lost with the Evo Touch? Its the re-sync part that is important (rather than just having the HR92 send the room temp to the main controller) as this affects the receiving of info from the controller. On many of the battery devices you can force a one-way send to the controller to refresh the data it sends, so it would be good to know if the menu button on the HR92 can be used for one-way send to the controller or if it forces a resync if the HR92 has lost sync/comms with the controller too.
