OPERATING
YOUR UNIT
The
operation
of your
heat
pump
system
is controlled
by the
indoor
thermostat.
You
simply
adjust
the
thermostat
and
it
maintains
the
indoor
temperature
at the
level
you
select.
Most
thermostats
of heat pump
systems
have
3 controls:
a temperature
control
selector,
a FAN control,
and a SYSTEM
or MODE
control.
Refer to your thermostat
owner's
manual
for more information.
To better
protect
your
investment
and to elinfinate
unnecessary
service
calls, fanfiliarize
yourself
with the following
facts:
1. During
heating,
increasing
the desired
temperature
setting
more than 2°F (1.1°C)
may cause the supplemental
heaters
to be turned
on for a short period
of time
to satisfy
the
demand.
Needless
use of the supplementary
heat reduces
potential
energy savings.
2. Ice or frost tends to form on the coil during
winter
heating
operation.
Your unit is designed
to automatically
melt the
ice. When
in this defrost
cycle,
it is normal
for steam
or
fog to rise from
the outdoor
unit,
and
for water
to drain
from
the outside
of unit.
Do not be alarmed!
To start
the unit:
1. Turn on the electrical
power
supply to unit.
2. Set MODE
control
to desired
mode
and select temperature.
To shut
off unit:
NOTE:
If the unit is being
shut down because
of a malfunction,
call your dealer as soon as possible.
1. Set system
MODE
control
to OFF.
2. Turn off the electrical
power
supply to unit.
Cooling
Mode
With the SYSTEM
or MODE
control
set to COOL,
your unit will
run in cooling
mode
until the indoor
temperature
is lowered
to the
level you have selected.
On extremely
hot days, your unit will run
for longer
periods
at a time and have shorter
"ofF' periods
than on
moderate
days.
Heating
Mode
With the SYSTEM
or MODE
control
set to HEAT, your unit will
run in heating
mode
until the room temperature
is raised
to the
level
you have selected.
Of course,
your unit will run for longer
periods
to maintain
a comfortable
environment
on cooler days and
nights
than on moderate
ones.
Supplemental
Heat
Your unit is your primary
heating
source. Your system
may also be
equipped
with a supplemental
heating
source
such as electric
heat.
On cold days and nights,
your system
will automatically
turn on
the supplemental
heat, as needed,
in order to maintain
the level of
comfort
you have selected.
When
your
heat
pump
needs
additional
heat
to
keep
you
comfortable
your thermostat
will turn on the supplemental
heat (if
equipped).
When
the thermostat
calls for supplemental
heat, you
may notice the indoor
fan increase
its speed.
Defrost
Mode
When
your unit is providing
heat to your home
or office and the
5 °
9o
outdoor
temperature
drops
below
4.
F (7._ C), moisture
may
begin
to freeze on the surface
of the coil. If allowed
to build
up,
