Pressing the ENTER key will take the interface down into a hierarchy of param-
eter selection menus (act, treat, days, probe and spnew setting).
Pressing the ENTER key in any of the parameter selection menus commits to
selection of the currently displayed parameter and causes the interface to de-
scend into the next parameter selection menu. All parameter selection menus al-
ternate between a blank display and the current selection in the right hand
display.
Pressing the CODE SELECT key in a selection menu cancels the current selec-
tion activity and ascends back up to the next higher selection menu (or to Cd51
display mode if that is the next higher).
If the operator does not press any key for five seconds the interface reverts to
normal system display and the current selection menu is cancelled, but any pre-
viously committed changes are retained.
Available parameters and parameter ranges are a function of configuration op-
tions and previously selected parameters as indicated above.
Parameter with the exception of "Act" may not be altered if Cd51 is re-entered if
"Act" is "On". When ACT has completed including reaching the new setpoint "do-
ne" on the left display and the MONTH DAY of completion on the right display
will be displayed as the second entry in the menu. Turning ACT off clears this
entry. This action also resets Cd51 to initial time remaining. ACT must then be
turned on to view or modify the additional parameters.
Whenever any auto Pre-trip test or Trip Start is initiated, ACT mode goes to OFF.
