GENERAL
The EconoMi$er
®
X system utilizes the latest technology
available for integrating the use of free cooling with mechanical
cooling for packaged rooftop units. The code compliant W7220
control system optimizes energy consumption, zone comfort,
and equipment cycling by operating the compressors when the
outdoor-air temperature is too warm, integrating the compressor
with outdoor air when free cooling is available, and locking out
the compressor when outdoor-air temperature is too cold.
Demand controlled ventilation is supported.
NOTE: This EconoMi$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
2
sensors are available for field installation.
Separate barometric relief dampers provide natural building pres-
surization 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 for package usage. See Table 2 for package contents.
See Table 3 for sensor usage.
