UI5 claims thermostat can't enter "Energy" mode

I recently purchased and installed a Honeywell ZWave thermostat (YTH8320ZW1007/U), it has an energy savings mode, which I have been using via my iPhone with the HomeWave app. When I try to use it via the Vera3 interface UI5, I get an error message “ERROR Thermostat does not support this mode”. I’ve done a search, and the following topic, related to an older beta version, is the only thing that comes up.


Does anyone have a suggestion for me? I want to start writing some Lua code that sets energy mode when I’m away, and I don’t know if it will work right unless this is resolved.
