Codes 19 and 20 determine the base section. Code 19 is the Return Air Plenum and determines if the unit has
back (a.k.a. horizontal) return air or bottom return air. The plenum is required for any outdoor air application
with an economizer (Code 20= BE, BY, DE, DY, EE, EY, FE, FY, GE or GY). The only case in which a plenum
is not required is when a 100% outdoor air damper and hood are ordered (C20= AE, AY).
Codes 21, 22, 23 determine the return air fan, motor and drives. These codes only pertain to units with a 0-100%
economizer (C20= DE, DY, EE, EY, FE, FY, GE or GY). The fan section parts, the fans, and the motors are listed
in this section. The drive components (fan sheave, motor sheave, belt, and fan bushing) are not listed as
they are unique to the unit. If a drive component is required you may use the number from the part and
cross reference it with the Drive Components Cross Reference, or contact Daikin McQuay Parts with
model and serial number information for identification.
Code 06 determines the panels used in final cabinet assembly (return air units only).
Code 09, the voltage, is part of the motor part number identification.
Notes
Code 12, the control system, comes into play when an economizer is present. The economizer comes with an
actuator motor on a MicroTech unit, but may not have a motor if the unit has controls by others (C12= YM, YC).
Code 14 determines if the return fan has an inverter, or variable frequency drive (VFD).
Code 15 determines what type of inverter was ordered, or if the inverter was field installed and controlled by
the Microtech III controller.
Code 16 determines the smoke detector which is located in the return air cabinet. C16= 1 or 3 if a smoke detector
(SD2) is present.
Code 17 determines the type of Enthalpy and Miscellaneous Auxiliary Controls included. The second digit of
Code 17 lists the inclusion of Freezstats, Phase Failure, Line Reactors, and Ground Fault protection. See the
Unit Code Index section to determine which options were specified.
Code 49 determines if the return air cabinet has a light (C49= E), fan belt guards (C49= D) or both (C49= F).
This damper assembly does not include an actuator or actuator linkage. A list of component parts
follows this page.
Note: The outdoor air damper with actuator (C20= AE) must have MicroTech III controls. Dampers
without actuators (C20= AY) must have controls by others (C12= YM, YC).
This damper assembly does not include an actuator or actuator linkage.
A list of component parts is two pages previous to this page.

The Exhaust damper assembly includes the damper and side baffles.
Note: Economizer with actuator (C20= *E) requires MicroTech Controls.
Without actuator (C20= *Y), requires controls by others (C12= YM, YC).
Economizer detail follows four pages after next.
This damper assembly does not include an actuator or actuator linkage. A list
of component parts is three pages previous to this page.
Note: Economizer with actuator (C20= DE) requires MicroTech Controls. Without actuator (C20= DY), requires controls by others. Economizer detail after
40" fan section detail.
This damper assembly does not include an actuator or actuator linkage.
A list of component parts is three pages previous to this page.
Note: Economizer with actuator (C20= DE) requires MicroTech Controls.
Without actuator (C20= DY), requires controls by others. Economizer
detail after 40" fan section detail.
This damper assembly does not include an actuator or actuator linkage.
Note: Economizer with actuator (C20= DE) requires MicroTech Controls.
