CAUTION
PERSONAL INJURY HAZARD
Failure to follow this caution can result in personal injury and
damage to the unit.
Cover the duct opening as a precaution so objects cannot fall
into the return duct opening. Be sure to remove the cover when
installation is complete.
GENERAL
The EconoMi$er
X system utilizes the latest technology
®
available for integrating the use of free cooling with mechanical
cooling for packaged rooftop units. The code compliant W7220
control system optimizes energy consumption, zone comfort,
and equipment cycling by operating the compressors when the
outdoor-air temperature is too warm, integrating the compressor
with outdoor air when free cooling is available, and locking out
the compressor when outdoor-air temperature is too cold.
Demand controlled ventilation is supported.
This EconoMi$er X system can be used with 1 or 2 speed indoor
fan motor units. (All other speed settings listed are for future use.)
The EconoMi$er X system utilizes gear-drive technology with a
direct-mount spring return actuator that will close upon loss of
power. The EconoMi$er X system comes standard with fault
detection and diagnostics (FDD), an outdoor air temperature
sensor, and mixed air temperature sensor (also called supply air
temperature sensor). Outdoor enthalpy, indoor (return) dry bulb
or enthalpy, and CO
sensors are available for field installation.

Standard integrated barometric relief dampers provide natural
building pressurization control. An optional power exhaust system
is available for applications requiring even greater exhaust
capabilities. The power exhaust set point is adjustable at the
EconoMi$er X controller.
See Table 1-3 for package usage. See Table 4 for package
contents. See Table 5 for sensor usage.
IMPORTANT: Read these instructions completely before
attempting to install accessory economizer.
