• Coil Guard - Customers can purchase a coil guard kit to
protect the condenser coil from damage. Additionally, this
kit stops animals and foreign objects from entering the
space between the inner condenser coil and the main
cabinet. This is not a hail guard kit.

INTELLI-Comfort™ control is factory installed. It
includes a supply air sensor, a return air sensor, and an
outside 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-Comfort™ using CO
outside air sensor. There are provisions for a field installed
dirty filter indicator switch, an air-proving switch, an Outside

algorithm to provide comfortable 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

line.
• Downflow Economizer - (With barometric relief) - The
economizer is provided with a single enthalpy input. The
economizer is 2% low leakage type. The economizer has
spring return, fully modulating damper actuators and is
capable of introducing up to 100% outdoor air. As the
outdoor air intake dampers open, the return air dampers
close. The changeover from mechanical refrigeration to
economizer operation is regulated by the standard single
enthalpy input. There is an optional input dual dry bulb
sensor available. To meet regulated air standards, the
economizer control accepts an optional CO

economizer control monitors outdoor air. The dual enthalpy
kit provides a second input used to monitor the return air.
With a dual input kit installed, the economizer control
compares the values of the two enthalpy or temperature
inputs and positions the dampers to provide the maximum
efficiency possible.

• Horizontal Economizer - (Without barometric relief) -
All features of the downflow economizer exist except you
must order the duct mount barometric relief separately.
You must order a 1EH0408 if you are installing a
power exhaust. You can order a 1RD0411 Barometric
Relief for horizontal flow economizer.

Factory-installed smoke detectors may be subjected to
extreme temperatures during "off" times due to outside air
infiltration. These smoke detectors have an operational
limit of -4°F to 158°F. Smoke detectors installed in areas
that could be outside this range will have to be relocated to
prevent false alarms.
