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 form number: 571006, or contact Daikin
McQuay Parts to ensure that the needed part(s) are correctly identified. The motors range anywhere from
1- 10 horsepower, and the fan wheels range from 15" FC to 40" AF.
Code 06 determines the panels used in final cabinet assembly (return air units only).
Notes
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= 1M, 2M, 4M, or 5M [original MicroTech] or L*, B*, E* or S* [MicroTech
II or MicroTech III]), 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 (or X
for units built prior to 2000) , then the unit has inverters, and cannot, therefore have wheels with variable inlet
vanes (which haven't been used on production units since 2003).
Code 15, determines if Variable Inlet Vanes (VIV) are present (these haven't been used on production units since
2003). If code 15= 2, they are present on the return fan. VIV is only available on units with 0- 30% economizers
(C20= BE, BY).
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 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.
Note: The outdoor air damper with actuator (C20= AE) must have MicroTech controls.
Dampers without actuators (C20= AY) must have controls by others (C12= YM, YC).

(C12= _D or _S) use p/n 060004705.
Codes 19 and 20 determine the base section. Code 19 is the Return Air Plenum, and is always BY (bottom return
air). Code 20 determines the type of Outdoor Air/Heat Recovery control is used. C20= 1E or 2E are 100% OA
Air units, and if C20= 3E the unit has an economizer.
Codes 21, 22, 23 determine the return air fan, motor and drives. 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. The motors range
anywhere from 1.5- 20 horsepower, and the fan is a 24" Single width airfoil wheel.
Code 24 determines if the Heat Wheel has a frost protection inverter (mounted in the section).
Code 06 determines the panels used in final cabinet assembly.
Code 09, the voltage, is part of the motor part number identification.
Code 14 determines if the return fan has an inverter, or variable frequency drive. If code 14 equals 2-9 , then
the unit has a return fan inverter.
Code 15, determines the type of Return Fan inverter (mounted in a separate section or the supply air section).
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 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= E).
ACT3 is used on the Outside Air Damper (used on all control options— C20=
1E, 2E or 3E). ACT4 is used on the Return Air Damper (used on units with
Economizer— C20= 3).
ACT3 is used on the Outside Air Damper (used on all control options— C20=

This is a replacement actuator. When replacing an original actuator, minor field
modifications may be required for proper installation.
Primary Codes that pertain: 25
Additional Codes that pertain: 06, 19, 20
Code 25 determines all of the section characteristics. If the first digit of Code 25 = A, D or E the filters are in an
angular rack, and if the first digit = F, G,or H the filters are in a flat rack. If the second digit = A there are throwaway
filters, B there are 30% eff. filters and C there are 30% eff. filters with antimicrobial Intersept. If the second digit =
D there are 65% eff. filters, E there are 95% eff. filters and G there are 95% eff. filters with antimicrobial Intersept.
Y there is no filter media at all. If Code 25 = BY or CY there is a blank section.
Code 06 determines the final assembly panel part numbers.
Codes 19 and 20 determine the Return Air section which has an effect on the final assembly panels.
This section pertains to the RPS and the RFS, but not the RCS.
Primary Codes that pertain: 26, 14, 15
Additional Codes that pertain: 06
Code 26 determines if a section is installed and if so, the size of the section. If Code 26= S or T there is a blank
section. If C26= S the section is 40" (this code is also necessary if the inverters are installed in this section),
and if C26= T the section is 52". If Code 26= Y, there is no section.
Code 06 determines the liners and insulation, and will affect the final assembly panels. For sheet metal
components that make up the Blank compartment, contact Daikin McQuay Parts to insure correct liners,
insulation and hardware are ordered.
This section pertains to the RPS and the RFS, but not the RCS.
Codes 14 & 15 determine if the unit has inverter(s) and if so where they are installed. If Code 14= 1, 2 or 4 AND
Code 25= S, there is a separate inverter section. If Code 14= 3, 5, 6, 7, 8 or 9, the inverter(s) are installed in the
Supply Air Section. If Code 14= Y, there are no inverters. Code 15 determines the inverter type. The Inverter
with Bypass is shown below. All components pertaining to the Inverter are listed in the Supply Air Section
Primary Codes that pertain: 27, 28
Additional Codes that pertain: 06
NOTE: Section D applies only to unit sizes 036 and 040. The Draw-Thru Evaporator Cooling Coil for unit
sizes 018- 030 is located in Section F- the Supply Air Section. The coils and their associated components
for the 018- 030 are listed in Section F.
Code 27 determines if there is a Section D. If Code 27= YYYY, then there is no section. If the code is CYYY
or CYYS then there is a unit cooling coil and drain pan (the "S" means the drain pan is stainless steel, a "Y" in
the fourth position indicates that the pan is galvanized). If Code 27= DYYY or DYYS, then the section contains
only a drain pan.
Code 28 will apply only if Code 27= CYYY or CYYS, and determines the coil characteristics. The coils changed
in mid 1997, so the code is necessary to determine the coil part number, as well as certain coil mounting
components. The chart on the following pages lists all the coil choices.
Code 06 determines the liners and insulation, and will affect the final assembly panels. For sheet metal cabinet
components, contact Daikin McQuay Parts with unit serial and/or G.O. number.

Inverters may be located in a separate section (Code 14= 1, 2 or 4, only inverters WITH bypass may be installed in a separate section), or
the Supply Air Section (Code 14= 3, 5, 6, 7, 8 or 9). The inverter and bypass controls are the same regardless of the installation location,
although the sheet metal components differ. The diagrams shown below apply to either a return air or supply air inverter (both may be
installed if code 14= 5). Even if Code 14= 8 or 9— where only a return air fan inverter is called for— the inverter and bypass controls are
still installed in the Supply Air Section.
** If unit was built between 10/04 and 3/05 Contact Daikin McQuay Parts to confirm installed components.

In 06/12 the design of PC7 was changed. Units equipped
wth the old style PC7 Switch require Retrofit Kit 910122413
for proper installation as old and new parts are NOT
interchangeable. The Switch only is p/n 910115489, the
Pneumatic Fitting is p/n 910122414, and the Support Bracket
is p/n 910122290.
MAT- Mixed Air Temperature Sensor (Until 2/04)
EFT- Entering Fan Temperature Sensor (After 2/04)
P/N is for MicroTech III Controls. For Original MicroTech controls
(C12= 1,2,3,4,5) use p/n 065829505. For MicroTech II controls
(C12= _D or _S) use p/n 060004705.

Primary Codes that pertain: 04, 34
Additional Codes that pertain: 06, 07, 08, 09, 12, 31
Code 04 determines what type of heat, if any, the unit employs, and code 34 defines the specific heating
characteristics. If Code 04= Y, and Code 34= YYYYYY there is no section. If Code 04= Y and Code 34= BBBBBB,
then there is a 40" Blank Access Section installed. Otherwise, see the nomenclature page for specific heat
section definition. This section is divided into four subsections: 1. Blank Access; 2. HW/Steam Heat; 3. Electric
Heat; and 4. Gas Heat.
Code 07 is the Gas Heat Burner Approval Code and affects many of the parts in the gas heat section depending
on whether the unit is UL approved (USA) or CSA approved (Canada).
Code 08 determines which generation of controls are installed which determines which electric heat controls are
used. Code 09 determines the Unit Voltage, which will have an effect on the electric heaters and their controls.
Code 12 determines the Control type and will affect the gas heat actuator motor. Code 31 is the supply fan
size, and affects the heat section's diffusers. Code 06 determines the insulation and liners and will affect the
Top Panel, Uprights, and Door Assembly part numbers. For sheet metal cabinet components, contact Daikin
McQuay Parts with unit serial and/or G.O. number.
This section pertains to the RPS and the RFS, but not the RCS.
