The EconoMi$er 2 system uses gear-drive technology with a
direct-mount spring return actuator that will close upon loss of
power. Differential dry bulb, enthalpy, and differential enthalpy
sensors are available for field installation. Field-installed CO
2
sensors are available. (See Table 5.)
Optional barometric relief dampers provide natural building
pressurization control. An optional power exhaust system is avail
-
able for applications requiring even greater exhaust capabilities.
The power exhaust set point is adjustable at the EconoMi$er 2
controller.
To see which economizer is used on specific Carrier, Bryant, or
ICP models see Tables 1-3. See Table 4 for package contents and
Table 5 for PremierLink
™
controller sensor usage.
Compliance
EconoMi$er 2 outside air dampers meet the ASHRAE (American
Society of Heating, Refrigeration, and Air-Conditioning
Engineers) 90.1-2016, IECC (International Energy Conservation
Code) 2015, and Title 24 2016 leakage requirements.
Economizers meet California Energy Commission Title 24-2013 /
2016 prescriptive section 140.4 (damper leakage etc.), and when
used with Carrier ComfortLink, RTU Open, PremierLink™,
SystemVu™, or I/O Flex 6126 control systems, meet mandatory
section 120.2.i for Fault Detection and Diagnostic requirements.
Economizers meet ASHRAE 90.1-2013 / 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 when used with Carrier ComfortLink, RTU Open,
PremierLink, SystemVu, or I/O Flex control systems.
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 when used with
Carrier ComfortLink, RTU Open, Premierlink, SystemVu, or I/O
Flex control systems meet 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.
Outside air and return air (volume) dampers are AMCA (Air
Movement and Control Association) rated. Relief air dampers are
also AMCA rated.
