ACCESSORIES AND COMPLIANCE
Accessories List
The EconoMi$er X system has several field-installed accessories
available to optimize performance. Refer to Table 4 for authorized
parts and power exhaust descriptions.
* When available order MicroMetl PN 9901-2022-DIFF JC2.
Compliance
Economizers meet California Energy Commission Title 24
mandatory section 120.2.i for Fault Detection and Diagnostic
controls.
Economizers meet ASHRAE 90.1 Fault Detection and Diagnostic
requirements.
Economizers meet IECC Fault Detection and Diagnostic
requirements.
NOTE: IECC requires differential return air sensor, which must be
ordered separately. See Accessory CRDIFRASN01A00.
INSTALLATION
See Fig. 1 for component locations.
1. Turn off power supply(s) and install lockout tag.
2. Remove the existing unit filter access panel. Raise the panel
and swing the bottom outward. The panel is now disengaged
from the track and can be removed and discarded. (See
3. Remove the indoor coil access panel and discard. (See
4. Slide the EconoMi$er X assembly into the rooftop unit. (See
5. Slide the EconoMi$er X assembly all the way back and into
the horizontal R/A (Return Air) opening. (See Fig. 3.)
NOTE: Be sure that the arrow on the actuator motor is pointing to
“Run” and not to “Test.” If the arrow is at “Test,” the Economizer
damper will drive open.
6. Attach O/A (Outside Air) panel over the panel opening, then
lift the economizer. Match the ID (inside dimension) of the
panel with the ID of the economizer, then attach using pro-
7. If the EconoMi$er X system will be operating with an
enthalpy outside air sensor, remove the factory installed
HH79AH001 dry bulb sensor from the front face of the
economizer (see Fig. 1), and install the accessory enthalpy
sensor HH57AC081 in the same location. Connect the (2)
wire gray harness with plug from the EconoMi$er X
assembly to the enthalpy sensor. See page 7 for wiring
diagram. Refer to page 8 “Installing Optional HH57AC081
Outside Air Enthalpy Sensor” section for more details on
enthalpy settings.
