uses an inside CO
sensor to perform Demand Ventila-
2
tion. It can also use an Outside CO
ferential Demand Ventilation. It uses a Patented Comfort
Ventilation algorithm to provide comfortable ventilation air
temperature. The patented economizer-loading algorithm
will protect the equipment when harsh operating condi-
tions exist. Humidity in the occupied space or return duct
can be monitored and controlled via humidity sensors and
the on-board connection for hot gas re-heat system. It
uses the INTELLI-Start™ algorithm to maximize energy
savings by recovering the building from the Unoccupied
Setpoints to the Occupied Setpoints just in time for the
Occupied Time Period to begin. The Simplicity® INTELLI-
Comfort™ balances space temperature, ventilation air
temperature, CO
and humidity for ultimate comfort.

•
SMOKE DETECTORS - (supply air & return air) The
smoke detectors stop operation of the unit by interrupting
Johnson Controls Unitary Products
sensor to perform Dif-
2
power to the control board if smoke is detected within the
air compartment.
Factory installed smoke detectors in the return air
may be subjected to freezing temperatures during
"off" times due to outside air infiltration. These
smoke detectors have an operation limit of 32°F to
131°F. Smoke detectors installed in areas that
could be outside those limitations will have to be
moved to prevent having false alarms.
•
COIL GUARD - Customers can purchase a coil guard kit
to protect the condenser coil from damage. This is not a
hail guard kit.
•
