for future expansion, or other factors which
affect equipment sizing."
(1) Add the following paragraph 503.4(b) (4) following para-
graph 503.4(b) (3) (e) at page 5-14 of the energy code:

may be used separately or in conjunction with
straight air conditioning units or other HVAC
systems. The manufacturer of electric resis-
tance comfort heating equipment shall make
available to prospective purchasers, designers,
or contractors, full load energy input, over
the range of voltages at which the equipment
is intended to operate."
(m) Subparagraphs 1, 2 and 3 of Subsection 503.7(a) on page
5-18 of the energy code are hereby amended to read as
"1. Where used to control heating only, a maximum

2. Where used to control cooling only, a minimum
temperature of 79 F.
3. Where used to control both heating and cooling, it
shall have a maximum heating mode temperature
setting of 72 F and a minimum cooling mode
temperature setting of 78 F and shall be capable
of operating the system heating and cooling in
sequence. It shall be adjustable to provide a
temperature range of up to 10 F between full
heating and full cooling in sequence. It shall be
adjustable to provide a temperature range of up to
10 F between full heating and full cooling, except
as allowed in 503.3(c)4b."
(n) The introductory paragraph of Section 503.9 in the energy
code as adopted March 21, 1979, remains as follows:
"All duct work shall be constructed and erected in
accordance with Standards RS -15, RS -16, RS -18, RS -18,
RS -19, or RS -20, as applicable, which Standards super-
sede the Standards in Section 502 of the Standard
Mechanical Code now or hereafter in effect as adopted
by the County. The other provisions of Chapter V of
the said Mechanical Code apply to the extent the specific
criteria is not addressed in any applicable RS Standards.
If there is a conflict between any provisions of Chapter V
of the said Mechanical Code as amended now or hereafter
and the RS Standards, the RS Standards shall control.
Subparagraphs (a), (b), and (c) of Section 503.9 are not
amended. This amendment continues from the original
