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 out

-

door-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

control 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

2

 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  Tables  1-3  for  package  usage.  See  Table  4  for  package

contents. See Table 5 for sensor usage.

 

 

 

IMPORTANT:  These  economizers  meet  all  the  economizer

requirements  as  specified  in  ASHRAE  90.1,  IECC  and

California’s Title  24.  Economizer  must  be  installed  square  to

avoid damper leakage or damper binding. Squareness tolerance

is ± 1/32-in.

IMPORTANT:  Read  these  instructions  completely  before

attempting to install the accessory economizer.
