Emergency Heat Mode (Super State)
The Emergency Heat mode is provided for situations where the UVC is in a mode
that does not normally allow heating, such as OFF, Cool, Night Purge, or Fan Only.
If Emergency Heat mode is enabled, the UVC can automatically force itself into the
Emergency Heat mode from OFF, Cool, Night Purge, Fan Only, Purge, Pressurize,
De-pressurize, and Shutdown. Units with software model 05 do not have primary or
secondary heating devices. In the event that the Emergency Heat mode is entered the
UVC will use auxiliary heat if available. See "Auxiliary Heat Signal" on page 37.
Auto Mode
Auto mode is provided so that the UVC can be set to automatically determine if heat-
ing or cooling is required. Auto mode is the default power-up UVC mode. Auto mode
is made up of the Heat, Cool mode “super states”. When the UVC is set to auto mode,
the UVC automatically determines which mode (Heat or Cool) to use.
