ADJUSTING
ROOM
TEMPERATURE
Pressing
either
the
"Up"
or
"Down" button will
increase
or
decrease
the set
temperature
by 2
degree increments.
Once
desired temperature
is
displayed,
press
set
button
to
lock into memory.
The
lights
on the
control panel will indicate
the
level
of
heater
operation—low
or
high.
BURNER
MODE
The
heater will automatically change
its
heat output until
the
desired room temperature
is
reached.
While
it
cycles,
you may
hear
the
circulation
fan
change speed.
Depending
on the
output required
to
maintain
the
desired
room
temperature,
the
indicator lights will illuminate
in the
following pattern:
LIGHT
PATTERN
High
4
indicators—On
Low
2
indicators—On
Off
*No
lights
on
*The
heater will shut itself
off
temporarily when
the
desired room temperature
has
been reached
and
restart automatically
when
necessary
to
maintain room temperature.
NOTE:
The
heater
may
display
room
temperature
4
degrees
above
set
temperature,
depending
on
heater
load
conditions,
before
shutting
itself
off.
INSTRUCTIONS
FOR
ECONOMY PLUS MODE
To
engage
the
economy plus mode, simply press down
the
button
labeled
"Economy Plus",
to
disengage press again.
NOTE:
Operation
switch
must
be
"ON"
and in
manual
mode.
This feature minimizes
the
"ON"
and
"OFF" cycling
of the
unit
by
allowing
it to
overshoot
the set
temperature
by 12
degrees instead
of the
normal
4
degrees.
The
advantages
of
this feature
are to
increase
the
overall efficiency
of the
unit
by:
1.
Reducing heat loss
during
the
prepurge
and
postpurge cycles.
2.
Reducing inefficient combustion associated with start
up and
shut down.
3.
Prolonging component life
by
decreasing expansion
and
contraction
of
internal parts.
NOTE:
This
feature
could
be
compared
to
driving
an
automobile
in
stop
and go
traffic
(regular
mode)
versus
highway
driving
with
cruise
control
engaged
(Economy
Plus
mode).
