AUTO-
CYCLES
Option
Blower control option for room sensor
applications during occupied periods.
•
Auto Cycle
: Blower cycles with
demand
•
On-Continuous 1
: blower is on
with either the occupancy sensor
or occupancy schedule indicates
occupied.
•
On-Continuous 2
: Blower is on only
when both the occupancy sensor
and occupancy scheduler indicates
occupied.
•
On-Continuous 3
: lower is on only
when both the occupancy sensor
and occupancy scheduler indicates
occupied. in addition, blower will be
on a minimum of 25% of the time
when occupancy scheduler indicates
occupied by the occupancy sensor
indicates not occupied. The 25%
minimum is achieved by turning
blower on for 30 minutes and off for
90 minutes.
