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, bottom return air, Top return air or side 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, GY, HE, HY, JE or JY). 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, GY, HE, HY, KE, KY, LE, LY, ME, MY, JE or JY). 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 form number:
571006, or contact Daikin McQuay Parts to ensure that the needed part(s) are correctly identified.
Code 24 determines if there is a prop exhaust fan and if so, whether it is a 2-fan or 3-fan arrangement.
Code 06 determines the panels used in final cabinet assembly (return air units only). For sheet metal components
that make up the Outdoor/Return Air Section, contact Daikin McQuay Parts to insure correct liners, insulation
and hardware are ordered.
Code 09, the voltage, is part of the motor part number identification.
Code 12, the control system comes into play when an economizer is present. The economizer comes with an
actuator motor on any MicroTech unit (C12= L*, B*, E* or S*]), but may not have a motor if the unit has controls by
others (C12= YC or YM).
Code 14 determines if the return fan has an inverter, or variable frequency drive. If code 14 equals 1-9 , then the
unit has inverters.
Code 15, determines the inverter type.
Code 16 determines if a smoke detector is located in the return air cabinet. If C16= 1 or 3, a smoke detector (SD2)
is present.
Code 17 determines the Enthalpy Control. If C17= Y* and the unit has an economizer there is a mechanical enthalpy
control (OAE). If C17= C*, there is a differential enthalpy control (OAE + RAE).
Code 49 determines if the return air cabinet has a light, switch and receptacle (C49= B), fan belt guards (C49= D)
or both (C49= F).

Complete assy includes the damper assy and linkage (no actuator) or actuator assy. For Damper components see the
following page.
Note: The outdoor air damper with actuator (C20= AE) must have MicroTech controls. Dampers without actuators (C20= AY)
must have controls by others (12= YM, YC).
