STAGE DELAY TIMER
Default ON. When ON, all stage delay timers
(stages 2, 3, and 4) are enabled and will serve to
bring on additional stage(s) of cooling or heating
on a timed basis (default 20 minutes) in cases
when the previous stage of heating or cooling will
not raise or lower the room temperature to the set
point in a given time.
When OFF is selected all stage delay timers are
disabled. This means stages are changed based
on the temperature and not their timer delays.
Scroll to STG DELAY TIMERS; and touch to
select the applicable stage delay timer. Touch < to
return to previous menu.
