Energy Conservation Program: Test 
Procedures for Central Air Conditioners and Heat Pumps; Correction 
AGENCY : Office of Energy Efficiency and 
Renewable Energy, Department of Energy. 
ACTION : Final rule; correcting 
amendments. 
SUMMARY : On January 5, 2017, the U.S. 
Department of Energy (‘‘DOE’’) published a final rule that made two sets of amendments to the test procedure for central air conditioners and heat pumps (‘‘CAC/HPs’’): amendments to the existing test procedure required for determining 
compliance with the current energy conservation standards; and establishment of a new test procedure that would be the basis for making 
efficiency representations as of the compliance date for any amended energy conservation standards. This document corrects typographical errors, omissions, and incorrect cross- references in the Code of Federal Regulations that resulted from the January 2017 final rule. Neither the errors nor the corrections in this document affect the substance of the rulemaking or any conclusions reached in support of the final rule. 
DATES : Effective December 2, 2021.

SUPPLEMENTARY INFORMATION : I. Background 
On January 5, 2017, DOE published a 
final rule regarding the Federal test 
procedure for central air conditioner and heat pumps. 82 FR 1426 (‘‘January 2017 final rule’’). The January 2017 final rule amended the test procedure for central air conditioners and heat pumps at title 10 of the Code of Federal Regulations (‘‘CFR’’) part 430 subpart B appendix M (‘‘Appendix M’’) and established a new test procedure at 10 CFR part 430 subpart B appendix M1 (‘‘Appendix M1’’). 82 FR 1426. Appendix M provides for the measurement of the cooling and heating performance of central air conditioners and heat pumps using the seasonal energy efficiency ratio (‘‘SEER’’) metric and heating seasonal performance factor (‘‘HSPF’’) metric, respectively. Appendix M1 specifies a revised SEER metric (‘‘SEER2’’) and a revised HSPF 
metric (‘‘HSPF2’’). The test procedures as amended and established in the January 2107 final rule for central air conditioners and heat pumps include a number of typographical errors, omissions, and incorrect cross- references, which may result in confusion in executing the test procedures. The errors and corrections are summarized in the Table I.1. 
TABLE 1.1—S UMMARY OF ERRORS AND CORRECTIONS  
CFR section(s) Description of error and correction Rationale 
10 CFR 429.16(a)(1) .......................................... Corrects cross-references regarding rep-
resented values related to multi-split sys-
tems, multi-circuit systems, and multi-head mini-split systems by: 
(1) Replacing ‘‘(c)(3)(ii)’’ with ‘‘(c)(3)(iii)’’. (2) Replacing ‘‘Additional representations are 
allowed, as described in paragraph (c)(3)(i) of this section.’’ with ‘‘Additional representa-tions are allowed, as described in para-graphs (c)(3)(i) and (c)(3)(ii) of this sec-tion.’’. Cross-references did not get updated when 
the January 2017 final rule added 10 CFR 429.16(c)(3)(i). 
10 CFR 429.16(f)(1)(i)(B), 10 CFR 
429.16(f)(2)(ii)(A), and 10 CFR 429.16(f)(4)(i)(B).Removes the language ‘‘(b)(3)(i)(C)’’ and 
‘‘(b)(3)(i)(B) and replaces with ‘‘(b)(3)(iii)’’ and ‘‘(b)(3)(ii)’’, respectively.Transcription error—cross-references not 
properly updated. 
Paragraph a of Section 3.6.4 of Appendix M 
and Paragraph a of Section 3.6.4 of appendix M1.Corrects the instruction regarding compressor 
speed for the H1
Nheating mode test.Instructions for compressor speed limitations 
for H1 Ntest incorrectly incorporated. 
Paragraphs b and c of Section 3.6.6 of appen-
dix M.Corrects incorrect references to HSPF2 in ap-
pendix M. HSPF2 is associated with appen-dix M1. The revision corrects the reference to ‘‘HSPF’’.Reference inadvertently made to HSPF2 rath-
er than HSPF. 
Section 4.1.3.2 and Section 4.1.4.2 of appendix 
M.Inserts missing inequalities in the titles, revis-
ing ‘‘Q ˙ck=1(Tj) BL(T j) Q˙ck=2(Tj),’’ to read 
‘‘Q˙ck=1(Tj) < BL(T j) < Q˙ck=2(Tj).’’.Inequalities inadvertently omitted from the 
January 2017 final rule.

TABLE 1.1—S UMMARY OF ERRORS AND CORRECTIONS —Continued 
CFR section(s) Description of error and correction Rationale 
Sections 4.2.5.1, 4.2.5.2, and 4.2.5.3 of appen-
dix M; Sections 4.2.5.1, 4.2.5.2, and 4.2.5.3 
of appendix M1;.Replaces cross-references to section ‘‘3.1.9’’ 
with ‘‘3.1.10’’.Cross-references inadvertently not updated. 
Section 4.2.5.1 of Appendix M; Section 4.2.5.1 
of appendix M1.Changes subscript on left side of equation for 
energy E from ‘‘hp’’ to ‘‘h’’ by replacing ‘‘E˙
hp(Tj) = Q˙hp(Tj)’’ with ‘‘E ˙h(Tj) = E˙hp(Tj)’’.Transcription error. 
Sections 4.2.5.1 of Appendix M; Section 4.2.5.1 
of appendix M1.Changes inequality for Case 2 of Section 
4.2.5.1 to reflect intent consistent with Sec-tions 4.2.5.2 and 4.2.5.3 by changing ‘‘T
o(Tj) > T cc’’ to ‘‘T o(Tj) < T cc’’.Transcription error. 
Section 4.2.6.c of appendix M; Section 4.2.6.c 
of Appendix M1.Changes designation of booster stage capac-
ity to use the correct superscript ‘‘k=3’’ by replacing ‘‘Q ˙;
hk=2(5)’’ with ‘‘Q ˙hk=3(5)’’ where 
the text describes what test is used to ob-tain the booster stage 5 °F capacity.Transcription error. Booster capacity denoted 
as k=3 in all other locations throughout test procedure. 
Section 4.2.6.2 of appendix M; Section 4.2.6.2 
of appendix M1.Changes the inequality in the equation of the 
title of Section 4.2.6.2 to be consistent with the text, ‘‘Capacity Is Greater Than or Equal to the Building Heating Load.’’ Re-places ‘‘<’’ with ‘‘≤’’.Incorrect inequality. 
Section 4.2.6.3 of appendix M; Section 4.2.6.3 
of appendix M1.Changes the title to specify the correct com-
pressor stage for the case, revising ‘‘High’’ to ‘‘Booster,’’ which is the k=3 compressor stage.Transcription error. Booster capacity denoted 
as k=3 in all other locations throughout test procedure. 
Section 1.2 of appendix M1 ............................... Inserts the word ‘‘minimum’’ missing in the 
definition for ‘‘minimum-speed-limiting vari-able-speed heat pump’’ to indicate which speed is higher than its value for operation in a 47 °F ambient temperature.Transcription error—missing word ‘‘minimum.’’ 
Section 3.1.4.7 of appendix M1 ......................... Replaces incorrect cross-reference to Section 
‘‘3.14.6’’ with ‘‘3.1.4.6’’.Transcription error. 
Paragraph d to section 3.6.4 Table 14 of ap-
pendix M1.Adds explicit description of the compressor 
speed to be used for the H4 25 °F full-ca-
pacity heating mode test, consistent with the intent as described in the July 2016 SNOPR and January 2017 Final Rule pre-amble discussions.Inadvertent omission of footnote. 
Section 4.1.4.2 of appendix M1 ......................... Replaces the single instance of ‘‘EER2’’ in the 
section with ‘‘EER’’.Transcription error. 
Section 4.1.3.2 of appendix M1 ......................... Removes extraneous ‘‘(’’ in the title line of the 
section.Transcription error. 
This document identifies and corrects 
these errors. Neither the errors nor the 
corrections in this document affect the substance of the rulemaking or any conclusions reached in support of the final rule. 
II. Need for Correction 
As published, the regulatory text in 
the January 2017 final rule may result in 
confusion due to incorrect symbols in the test procedure equations, typographical errors, incorrect cross- references, and missing footnotes. The following sections provide the rationale for each correction. Because this final rule would correct errors in the text and provide additional detail without making substantive changes in the January 2017 final rule, the changes addressed in this document are technical in nature. A. Cross-References at 10 CFR 
429.16(a)(1) 
The January 2017 Final Rule added 
provisions for determining represented values for split systems in 10 CFR 429.16(c)(3)(i) but did not make corresponding edits to the cross- references contained within 10 CFR 429.16(a)(1), which describes the additional representations that are allowed for such systems (i.e., in 
addition to the required representations). This document corrects this error by updating these cross-references. 
B. Transcription Errors at 10 CFR 
429.16(f) 
In the January 2017 Final Rule, DOE 
established provisions for represented values required by the Federal Trade Commission—among them the annual operating cost in cooling mode. These sections rely on the calculated quantities for cooling capacity and SEER in order to determine operating costs but contain incorrect cross-references to the sections where these quantities are calculated. This document corrects the cross-references to refer to the correct sections for represented values of cooling capacity and SEER as adopted by the January 2017 Final Rule. 
C. Reference to H1
NTest in Section 3.6.4 
of Appendix M and Appendix M1 
In the January 2017 Final rule, DOE 
revised the requirement regarding 
compressor speed for the H1 Nheating 
mode test to ‘‘allow the compressor speed used for the H1
Ntest to be lower 
than used for the A2 test, provided that the H1
Ncapacity is no lower than the 
A2 cooling capacity.’’ 82 FR 1426, 1445. However, in codifying this revision in section 3.6.4 of appendix M and section 3.6.4 of appendix M1, DOE did not properly incorporate the changes. In appendix M, DOE inadvertently referred to the H1
2capacity instead of the H1 N 
VerDate Sep<11>2014 16:00 Dec 01, 2021 Jkt 256001 PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 E:\FR\FM\02DER1.SGM 02DER1lotter on DSK11XQN23PROD with RULES168391 Federal Register / Vol. 86, No. 229 / Thursday, December 2, 2021 / Rules and Regulations 
capacity when making the comparison 
to the A2 cooling capacity. In appendix M1, DOE omitted the language entirely that allowed the H1
Ncompressor speed 
to be lower than the speed used for the A2 test provided that the H1
Ncapacity 
is no lower than the A2 cooling capacity. This document corrects these errors to reflect the appropriate compressor speed limitations for the H1
Ntest that were adopted in the 
January 2017 Final Rule in both appendix M and appendix M1. 
D. Reference to HSPF in Section 3.6.6 of 
Appendix M 
The January 2017 Final Rule 
established the HSPF2 metric as measured per the newly created appendix M1. The HSPF2 metric is not defined for appendix M and does not apply in any section of that appendix. Rather, the applicable heating metric for appendix M is Heating Seasonal 
Performance Factor (‘‘HSPF’’). This document replaces two erroneous instances of HSPF2 with HSPF in paragraphs b and c of section 3.6.6 of appendix M. 
E. Inequality Symbols in Sections 4.1.3.2 
and 4.1.4.2 of Appendix M 
The January 2017 Final Rule retained 
testing provisions in appendix M to calculate the electrical power consumption of CAC/HPs when building load is between minimum and maximum capacity in order to satisfy the building cooling demand. For two- stage CAC/HPs, section 4.1.3.2 details the case where the system operates between low (k=1) compressor stage and 
high (k=2) compressor stage in order to satisfy demand. For variable-speed CAC/HPs, section 4.1.4.2 details the case where the system operates at an intermediate compressor speed ‘‘i’’ that is between the low and high compressor 
speeds. In both cases, the title text for these sections reflects the intent of establishing a range of operation. However, in the following inequalities (which restate the title text), the inequality symbols were inadvertently omitted. This document adds the missing inequalities to reflect what was intended in the January 2017 Final Rule. 
F. Cross-References in Sections 4.2.5.1, 
4.2.5.2, and 4.2.5.3 of Appendix M and Appendix M1 
The January 2017 Final Rule retained 
provisions in sections 4.2.5.1, 4.2.5.2, and 4.2.5.3 of appendices M and M1 for additional steps to calculate HSPF (or HSPF2 in the case of appendix M1) for heat pumps having heat comfort controllers. These sections each contain a case where outdoor bin temperatures are greater than the maximum supply 
temperature, T
CC, and reference section 
3.1.9 of the respective appendix for calculating T
CC. However, section 3.1.10 
is the correct cross-reference for calculating T
CC. This document corrects 
the cross-reference from 3.1.9 to 3.1.10 in accordance with the January 2017 Final Rule. 
G. Symbol Subscripts in Section 4.2.5.1 
of Appendix M and Appendix M1 
Section 4.2.5.1 of both appendix M 
and appendix M1 specify calculating the space heating capacity and electrical power of the heat pump, and to denote these capacities and electrical power by using the subscript ‘‘hp’’ instead of ‘‘h’’. Case 1 of section 4.2.5.1 of both appendices specifies determining total electrical power consumption E
h(Tj) as 
specified in section 4.2.1 of the same appendix, and provides an id est (‘‘i.e.’’) statement to illustrate the replacement 
of subscript ‘‘h’’ with ‘‘hp’’. Rather than state E
h(Tj) = E hp(Tj) as intended, the 
subscript ‘‘h’’ was inadvertently replaced with ‘‘hp’’ on both sides of the equation. This document corrects the errors in these sections. 
H. Inequality Symbol in Section 4.2.5.1 
of Appendix M and Appendix M1 
In sections 4.2.5.1, 4.2.5.2, and 4.2.5.3 
of both appendix M and appendix M1, Case 1 of each section covers instances where supply air temperature is greater than or equal to the comfort controller maximum supply temperature (i.e., T
o(Tj) ≥ Tcc). Case 2 covers the 
complimentary scenario where supply air temperature is less than the comfort controller maximum supply temperature (i.e., T
o(Tj) < T cc), such that 
collectively the two Cases cover the full range of possible supply air temperatures in comparison to the comfort controller maximum supply temperature. In section 4.2.5.1 of both appendices, the ‘‘less than’’ symbol in Case 2 was inadvertently codified as a ‘‘greater than’’ symbol. This document corrects this symbol to ‘‘less than.’’. 
I. Symbol Superscript in Section 4.2.6.c 
of Appendix M and Appendix M1 
The January 2017 Final Rule 
established provisions for testing of triple-capacity northern heat pumps, which utilize a third distinct stage of heating capacity—denoted as ‘‘boost’’ or ‘‘booster’’—that is higher than both the ‘‘high’’ and ‘‘low’’ stages. Section 4.2.6 of both appendix M and appendix M1 describes additional steps for HSPF calculation for triple-capacity northern heat pumps, referring to boost capacity with the superscript notation ‘‘k=3’’ in all but one instance: In section 4.2.6.c, the boost capacity is erroneously 
referred using the superscript notation ‘‘k=2’’. (Elsewhere in the test procedure, the notation ‘‘k=2’’ is used to refer to the ‘‘high’’ stage.) This document corrects that error by updating the superscript to ‘‘k=3’’ to be consistent with the intent established by the January 2017 final rule. 
J. Inequality Symbol in Section 4.2.6.2 of 
Appendix M and Appendix M1 
The January 2017 Final rule amended 
provisions for HSPF calculation of triple-capacity northern heat pumps in section 4.2.6. The title of section 4.2.6.2 describes cases where the heat pump operates at high (k=2) compressor capacity at temperature T
jand its 
capacity is greater than or equal to the 
building load (i.e., building load is less 
than or equal to the compressor capacity). In the inequality immediately following, the building load is listed 
first, and a ‘‘less than’’ symbol ‘‘<’’ is erroneously used rather than a ‘‘less than or equal to’’ symbol (‘‘≤’’). This document corrects the symbol using ‘‘≤’’ to indicate a building load less than or equal to capacity, to be consistent with the intent of the section title as established by the January 2017 Final Rule. 
K. Reference To Booster Capacity in 
Section 4.2.6.3 of Appendix M and Appendix M1 
As discussed in paragraph I, the 
January 2017 Final rule established provisions for HSPF calculation of triple-capacity northern heat pumps in section 4.2.6. Section 4.2.6.3 describes cases where the heat pump operates at the (k=3) compressor capacity (i.e., boost capacity) at temperature T
jand its 
capacity is greater than or equal to the building load. The title of this section erroneously refers to the (k=3) compressor capacity as ‘‘high.’’ Instead, the (k=3) compressor capacity should be referred to as the ‘‘booster’’ capacity (the ‘‘high’’ (k=2) capacity is covered by section 4.2.6.2). This document corrects the title of section 4.2.6.3 to be consistent with the intent established by the January 2017 Final Rule. 
L. Missing Word ‘‘Minimum’’ in Section 
1.2 of Appendix M1 
In the January 2017 Final rule, DOE 
proposed a definition for ‘‘minimum- 
speed-limiting variable-speed heat pump’’ to refer to heat pumps that vary the minimum compressor speed when operating in outdoor temperatures that are in the range for which the minimum speed performance factors into the HSPF calculation (i.e., between 35 °F 
and 62 °F). 82 FR 1426, 1458. However, 
VerDate Sep<11>2014 16:00 Dec 01, 2021 Jkt 256001 PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 E:\FR\FM\02DER1.SGM 02DER1lotter on DSK11XQN23PROD with RULES168392 Federal Register / Vol. 86, No. 229 / Thursday, December 2, 2021 / Rules and Regulations 
in codifying this definition in section 
1.2 of appendix M1, DOE inadvertently omitted the word ‘‘minimum’’ when referring to compressor speed at 47 °F. This document adds the word ‘‘minimum’’ to the definition of minimum-speed-limiting variable-speed heat pump to reflect the intent established by the January 2017 Final Rule. 
M. Cross-Reference in Section 3.1.4.7 of 
Appendix M1 
The January 2017 Final Rule 
established provisions in section 3.1.4.7 of appendix M1 for determining the heating nominal air volume rate to be used in HSPF2 testing. This section omitted a period and erroneously cross- references section 3.14.6 for adjusting airflow—section 3.1.4.6 is the proper cross-reference. This document corrects these errors. 
N. Missing Footnote in Table 14 of 
Appendix M1 
Compressor speeds for variable-speed 
compressor systems are specified in Table 14 in section 3.6.4 of appendices M and M1. These sections are supposed to include footnotes that specify the ‘‘Heating Full’’ compressor speed at different outdoor temperature test conditions for systems containing a variable-speed compressor. However, at the optional H4
2heating test condition 
(5 °F outdoor temperature) in appendix 
M1, the footnote is missing. (There is no H4
2test condition for variable-speed 
heat pumps in appendix M so no 
footnote is required.) For all other test conditions that utilize a ‘‘full’’ compressor speed, Table 14 to appendix M1 includes footnotes describing the meaning of ‘‘full’’ compressor speed in the context of each test condition. To specify the H4
2compressor speed for 
variable-speed heat pumps, a footnote is being added to Table 14 in appendix M1 to specify that the ‘‘Heating Full’’ speed refers to the maximum speed that the system’s controls would operate the compressor in normal operation at 5 °F ambient temperature. 
This correction is consistent with the 
discussion provided in the August 24, 2016 supplemental notice of proposed rulemaking (‘‘SNOPR’’), in which DOE stated that the full-speed compressor operation for variable-speed heat pumps could be very different at 5 °F than it is 
at 17 °F, thus an extrapolation of performance below 5 °F using the [17 °F compressor speed] trend between 17 °F and 5 °F is not appropriate. 81 FR 58164, 58193 (‘‘August 2016 SNOPR’’). The regulatory text in the August 2016 SNOPR provided instructional footnotes as to the appropriate ‘‘Heating Full’’ compressor speed for the heating test conditions except for the optional H4
2 
heating test condition. 82 FR 58164, 58238. Comment was not received on the appropriate compressor speed at the 5°F condition, and the erroneous 
omission of the footnote was carried over into the final rule, which adopted the proposal in the August 2016 SNOPR. 82 FR 1426, 1459, 1560. This correction also aligns with current industry test procedures for CAC/HPs (AHRI 210/240 2023) which includes a footnote in the test conditions table for variable-speed heat pumps specifying that the full compressor speed to be used at the 5 °F heating test condition is the maximum speed the system controls would operate the compressor at 5 °F ambient temperature. 
O. Reference to EER in Section 4.1.4.2 
of Appendix M1 
Section 4.1.4.2 of appendix M1 
specifies several equations in which variations of the EER metric are used. One of these equations contains the term EER
k=2. In the ‘‘where’’ statement 
following the equation, which defines each symbol used in the equation, EER
k=2is erroneously referred to as 
EER2k=2. This document corrects this 
error by referring instead to EERk=2. 
P. Extraneous Symbols in Section 4.1.3.2 of Appendix M1 
The title of section 4.1.3.2 of 
appendix M1 contains extraneous ‘‘(’’ symbols preceding the terms BL(T
j) and 
Qck=2(Tj). This document removes these 
extraneous symbols, consistent with the analogous terms in section 4.1.3.2 of appendix M. 
III. Procedural Issues and Regulatory 
Review 
Pursuant to the Administrative 
Procedure Act, 5 U.S.C. 553(b), DOE has determined there is good cause to find that prior notice and opportunity for public comment on the changes contained in this document are impracticable, unnecessary, or contrary to the public interest. Neither the errors nor the corrections in this document affect the substance of the January 2017 Final Rule or any of the conclusions reached in support of the final rule. Providing prior notice and an opportunity for public comment on correcting objective, typographical errors and omissions that do not change the substance of the test procedure serves no useful purpose. As such, this rule is similarly not subject to the 30- day delay in effective date requirement of 5 U.S.C. 553(d) otherwise applicable to rules that make substantive changes. DOE has also concluded that the 
determinations made pursuant to the 
various regulatory review requirements applicable to the January 2017 final rule remain unchanged for this final rule technical correction. These determinations are set forth in the January 2017 final rule. 84 FR 1426, 1463–1468.

a. Conduct one maximum temperature test 
(H0
1), two high temperature tests (H1 Nand 
H1 1), one frost accumulation test (H2 V), and 
one low temperature test (H3 2). Conducting 
one or more of the following tests is optional: An additional high temperature test (H1
2), an 
additional frost accumulation test (H2 2), and 
a very low temperature test (H4 2). Conduct 
the optional high temperature cyclic (H1C 1) 
test to determine the heating mode cyclic- degradation coefficient, C
Dh. If this optional 
test is conducted but yields a tested C Dhthat 
exceeds the default C Dhor if the optional test 
is not conducted, assign C Dhthe default 
value of 0.25. Test conditions for the nine tests are specified in Table 14. The compressor shall operate at the same heating full speed, measured by RPM or power input frequency (Hz), as the maximum speed at which the system controls would operate the compressor in normal operation in 17 °F 
ambient temperature, for the H1
2, H2 2and 
H3 2Tests. The compressor shall operate for 
the H1 Ntest at the maximum speed at which 
the system controls would operate the compressor in normal operation in 47 °F 
ambient temperature. Additionally, for a cooling/heating heat pump, the compressor shall operate for the H1
Ntest at a speed, 
measured by RPM or power input frequency (Hz), no lower than the speed used in the A2 test if the tested H1
Nheating capacity is less 
than the tested A2 cooling capacity.
