  • Decreased the time delay between turning channel 139 OFF and hiding the weather alert icon.

  • Resolved an issue where the screensaver could temporarily run, even though it is set to off.
  • Resolved an issue where the clock does not update while the user is in the Advanced Settings pages.
  • Resolved an issue where extra channel information could be sent by the thermostat.
  • Resolved an issue where the thermostat would send extra information in response to a ST command while in Program Mode.
  • Resolved an issue where the thermostat would sometimes not automatically revert to Program Mode at the start of the next program cycle.

Hot Fix for the ViewStat Color Communicating Thermostat Firmware (v.3.12 Available from AMX Technical Support)

  • Fixes - Viewstats unable to change the temperature at night. Users couldn't change the temperature, when in "Sleep" program schedule, while in program mode. The only way to adjust it was to change it to permanent hold.
  • Fixes - ViewStats falling back into sleep set points during other program modes time frame. Once the setpoint with the minutes other than zero was encountered the stat would revert to the previous set point for the duration of the minutes from the top of the hour to that minute mark.
  • Fixes - Comfort recovery did not come on until 12am. When 2-hour cycle occurs over midnight comfort recovery did not come on until 12a when 2-hour cycle occurs over midnight.
  • Fixes - AM is AM but PM is AM. If you set program mode times to be all AM the thermostat Program time would still trigger like they were PM times.
