Honeywell thermostat and "Auto Change Over"?

My Honeywell (YTH8320ZW1007/U) is working well with ZWave and the ISY.

 

The manual says the thermostat supports "Auto Change Over", and this feature can be set from the touch screen, but "Mode - Auto" not available for a program on my ISY?

 

The Z-wave section of Honeywell's manual reads:

Thermostat Mode
Other devices (controllers) are able to change the thermostat mode change of the thermostat. After the message is received by the thermostat, the thermostat mode change is changed to
desired value (if this value is possible).
Seven possible modes are available for the thermostat: Heat / Cool / Off / Auto / Energy Saving 
Heat / Energy Saving Cool / Em Heat. The number of allowed selections depends on the actual configuration of the thermostat. The thermostat uses "Thermostat Mode Supported" report command class to tell other devices the actually supported thermostat modes.

I can select mode - Auto from UDAjax, but "Mode - Auto" is not an option for a program?

Good morning,

what is parameter 0300 set to in your tstat? make sure that is set to 1 via the touch screen. I think default is 0

 

I can tell you that in ISY version 5.02 that I have, mode-auto is available inside a program.

 

cheers.
