• DISCONNECT SWITCH - For gas heat units and cooling
units with electric heat, a HACR breaker sized to the unit
is provided. For cooling only units, a switch sized to the
largest electric heat available for the particular unit is
provided. Factory installed option only.

• DOUBLE WALL CONSTRUCTION - Optional double wall
construction is available to provide smooth inner surfaces
for easy and effective cleaning to reduce risk of dirt and
bacterial accumulation. Fiberglass insulation is
sandwiched between heavy gauge steel sheets to form a
durable, rigid casing to withstand higher working
pressures and impact forces. The heavy-duty construction
provides excellent acoustic and thermal insulation and
eliminates erosion of insulation material and
contamination of the air stream.

Simplicity® INTELLI-Comfort™ CONTROL - The York®
Simplicity® INTELLI-Comfort™ control is factory installed. It
includes a supply air sensor, a return air sensor, and an out-
side air sensor. There are provisions for a field installed dirty
filter indicator switch, an air-proving switch, an Outside Air
Humidity sensor, a Return Air Humidity sensor, an Inside IAQ
sensor, and an Outside Air IAQ sensor. Construction mode
operation, 365-day real time clock with 7 day programming
plus holiday scheduling is built-in. Two different modes of
demand ventilation are achieved through the INTELLI-Com-
fort™ using CO

Patented Comfort Ventilation algorithm to provide comfort-
able ventilation air temperature. The patented economizer-
loading algorithm will protect the equipment when harsh
operating conditions 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 Unoccu-
pied Setpoints to the Occupied Setpoints just in time for the
Occupied Time Period to begin. The Simplicity® INTELLI-
Comfort™ balances space temperature, ventilation air tem-
