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 an
outdoor air temperature sensor, 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 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.
Compliance
Economizers meet California Energy Commission Title 24-2016
prescriptive section 140.4 (damper leakage etc.), and mandatory
section 120.2.i for Fault Detection and Diagnostic controls.
Economizers meet ASHRAE 90.1-2016 damper leakage
requirements as stated in Section 6.5.1.1.4 and Table 6.4.3.4.3,
and meet 2016 Fault Detection and Diagnosis requirements in
section 6.4.3.12.
Economizers meet IECC 2012 section C402.4.5.2 and, IECC
2015 sections C403.2.4.3 and C403.3.3.5 for outside air, return
air, and relief air damper leakage requirements, and IECC 2015
section C403.2.4.7 for Fault Detection and Diagnostic
requirements.
NOTE: IECC 2015 section C403.2.4.7.1 requires differential
return air sensor, which must be ordered separately.
Relief air, outside air, and return air (volume) dampers are AMCA
rated.
IMPORTANT: Read these instructions completely before
attempting to install the accessory economizer.
