BOILER OPERATING TEMPERATURE
With power
turned
on,
control
module
receives a signal from
the
temperature sensor
and
displays boiler temperature.
The
control
knob
labeled
BOILER
TEMP
is u
sed
to
adjust
the
operating temperature setpoint,
turning
clockwi
se
to
increase
temperature
sett
ing
and
counterclockwise
to
decrease. When
the
knob
is
turned
to
adjust temperature the display will brighten
to
indicate adjustment mode. After temperature is
set
to
desired
value, displ

BOILER ECONOMY SETTING
Th comply with
Department
of
Energy regulations, the
contro
l
module circulates available
hot
water before
turn
ing on the boiler
to
attempt
to
satisfy a call for heat. While attempting
to
satisfy
th
e
heat
demand,
the control module also monitors
th
e boiler
temperature changes via
the
temperature sen
sor
and
determines
whether
or
not
the
available h
ot
water will satisfy the
demand,
adjusting the time delay
to
turn
on
th
e boiler until
it
determines
th
at
additional heat will
be
needed. The knob label
ed
ECONOMY

provides
an
adjustment between maximize

IMPORTANT
In
accordana! with Section 325 (f) (3)
of
the Energy
Policy
and
Conservation Act,
this
boiler is equipped with a feature
that
saves energy
by
reducing
the
boiler water temperature
as
th
e heating l
oad
decreases. This feature is
equipped
with
an
override which is provided primarily
to
permit
the
use
of
an
external energy management system
that
serves the same
function.

THIS OVERRIDE MUST
NOT
BE
USED UNLESS AT LEAST
ONE
OF
THE
FOLLOWING
CONDIT
IONS IS TRUE:
An
external energy manage
ment
system
is
installed
that
reduces
the
boiler water temperature
as
the heating load
decreases.
This boiler
is
part
of
a
modular
or
multiple boiler system
having a total
input
of
300,000 BTU/hr
or
greater.
This boiler
is equipped with a tankless coil.
