Lockout Lights; Preseason Inspection; Thermostat Operation - Econar GeoSource 2000 GV Series Installation And Operating Instructions Manual

A. Filter
The GeoSource 2000
heat
pump is equipped with
a
disposable air
filter.
This
filter
should
normally
be
replaced
once
a
month during normal usage.
During
extreme
usage or
if
system
performance
has decreased,
the
filter
should
be
replaced more often.
A dirty filter
will
reduce
the airflow to the system. This
decrease
in airflow
will
reduce the
efficiency
and
comfort
level
of
the
system. In
the
heating
mode,
reduced
airflow
may increase the cost of operation
and,
in extreme
cases,
cause system
lockout
due
to high refrigerant pressures.
In
the
cooling
mode, reduced airflow may
reduce
cooling
capacity
and
in
extreme
cases
ice
the
aircoil over,
causing
system
shutdown
due to
low
refrigerant pressures.
If
another
filter
is used
in place of
the
factory
specified
filter,
it
should
also be cleaned
or replaced
in
a
timely
manner.
Be careful
in
selecting optional
filters
so
that
excessive
external
resistance
to airflow is not induced.
B.
Lockout Lights
A
lockout
light
on the
thermostat
will
light to indicate
major
system
problems. If
lockout
occurs,
follow
the
procedure below:
1)
Check
for
a
clean
filter
and
correct water supply
from
the
earth loop or well water
system.
2)
Reset
the
system
by disconnecting power
at the
circuit
breaker
for
one minute, and then
reapplying
power.
3)
If
shutdown reoccurs,
check the
indicator lights on
the
controller in
the
unit
and
review
the
lockout
froubleshooting guide in
section
XII
of this manual.
4)
If lockouts persist,
call your ECONAR dealer. Do
not continuously
reset the
lockout condition or
damage
may occur.
C. Preseason Inspection
Before
each season, the
air coil, drain pan,
and condensate
drain should be inspected and cleaned
as
follows:
-
Turn
offcircuit
breakers.
-
Remove
access
panels.
-
Clean air
coil by
vacuuming
it
v/ith
a
soft-brush
attachment.
-
Remove
any
foreign
matter
from
the drain
pan.
-
Flush pan
and drain tube
with
clear water.
-
Replace
access
panels and
return power to
the
unit.

THERMOSTAT
OPERATION
This
section
covers
basic operation of the
standard
2-heat
l-cool
thermostat that ECONAR carries. This
thermostat
is
ECONAR part number
7O-2OO2,
Honeywell part
number T8511G.
If
your thermostat is
a
different
style,
please
refer to
the
instructions supplied with
that
thermostat.
The settings of
the
thermostat
are

the
mode that the thermostat operates
in.
The

system
settings
are:
1.
Em. Heat - Conffols backup heating. In this
mode,
the heat
pump's
compressor is locked out,
and
only
the
backup heating elements
(if
installed)
operate.
2.
Heat - Controls normal heating operation.
3.
Off-
Both
heating
and

Note:
When
the
thermostat is
set
to
Auto,
there
must
be
at least
a
2T
difference between the Heating setpoint
temperature
and the
Cooling setpoint temperature.
Ths "Fan"
button controls the operation
of
the heat
pump's blower.
The Fan button
has
two
settings:
1.
On
