Dead Band
Set the offset to the proportional band. With a
negative value, both heating and cooling outputs
are active when the process value is near the set
point. A positive value keeps heating and cooling
outputs from fighting each other.

Profile Status Menu
(menu appears if PM6 R _ _ _-_ _ _ _ A _ _)
* Some parameters in the Profile Status Menu can be changed for the
currently running profile, but should only be changed by knowledgeable
personnel and with caution. Changing parameters via the Profile Status
Menu will not change the stored profile but will have an immediate im-
pact on the profile that is running.
Changes made to profile parameters in the Profiling Pages will be
saved and will also have an immediate impact on the running profile.
Note: Some values will be rounded off to fit in the four-character display. Full values can be read with other interfaces.
If there is only one instance of a menu, no submenus will appear.
