Your WaterFurnace Premier2 series
®
:
the best in GeoExchange heating and cooling
Thank you for purchasing a WaterFurnace Premier2 series GeoExchange heating and cooling
system. You have joined hundreds of thousands of smart owners all over the world who have
discovered that GeoExchange systems are ideal for heating, air conditioning and domestic water
heating. It’s the only system that does it all in one unit!
GeoExchange technology is ideal because it delivers what you want and what our world
needs:
• lowest operating cost of any heating and cooling system
• most energy efficient system available
• very comfortable with even temperature and humidity control
• quiet operation with no noisy outside equipment
• precise temperature control
• highly reliable with industry-proven components
• safe and clean with no flame, chimney or odors
• backed by the industry’s best warranties
• low maintenance requirements
• improves the environment by not burning fossil fuels
• no carbon monoxide emissions
Energy Efficient
GeoExchange systems are extremely energy efficient since they only use electricity to power
the pump, compressor and fan. These components transfer heat stored within the earth. As a
result, GeoExchange systems use far less electricity than outdoor air-to-air heat pumps and
conventional systems. In fact, they typically deliver about 3 to 4 times more energy than they
consume.
Environmentally Beneficial
GeoExchange systems are also environmentally advantageous because they don’t burn fossil
fuels, eliminating “greenhouse gas” emissions into the air. They use far less refrigerant than
air-to-air heat pumps or air conditioners, and are factory sealed to prevent leakage. And, they
reduce the need for more coal-fired or nuclear power plants by placing less energy demand on
our current capability to produce electricity.
You’ve made the ideal choice for everyone!

How does GeoExchange energy keep me
warm in the winter and cool in the summer
at savings of 30 to 60% over my current
energy costs?
No matter where you live, the underground temperature stays relatively constant all year,
even though outdoor temperatures vary greatly. GeoExchange systems harness the free,
renewable, natural supply of energy stored underground… and use it for heating, air
conditioning and hot water. One system keeps you comfortable in both winter and summer.
The basic principle of a GeoExchange system is to transfer heat produced by the sun and
stored within the earth into the structure during winter, and to remove heat from indoors in
summer and return it to the cooler earth. Water is used to carry this heat either by circulating
through an underground closed loop piping system or by directly pumping ground water.
During the heating season
Water circulating through a “loop” of underground pipe absorbs heat from the earth and
carries it to the Premier2 unit which extracts the heat, compresses it to a higher temperature
and distributes it via a duct system.
During the cooling season
The Premier2 unit extracts heat from the air and transfers it to the circulating water in the
underground loop system where it is dissipated into the cooler earth.
Hot water options
Depending on the options you have chosen, your GeoExchange system can also provide
some or all of your domestic hot water needs. If you have a unit with the hot water assist
feature built in, whenever the unit is operating (except 2nd or 3rd stage heat or emergency
heat) it will provide a portion of your hot water needs. If your system incorporates a separate
Premier Plus unit, it will provide all your hot water needs, even when your system is not
heating or cooling.
Zone control
An optional IntelliZone system is available to provide the ultimate in comfort and efficiency
to your system. This system electronically controls the operation of dampers in the duct
system to provide different zones with just the right amount of conditioning.

Premier2 Owner’s Manual
Is there more than one way
to install GeoExchange?
There are several different methods used to install a GeoExchange system. Your indepen-
dent WaterFurnace dealer will assist you in choosing the right one for your space. Our dealers
have been thoroughly trained on GeoExchange applications and are supported by the industry’s
best computer software to ensure that you receive the
right system.
Open loop systems
A GeoExchange open loop system uses ground water
as a direct energy source when good quality well water is
available at a reasonable pumping depth. A good water
discharge system is also required, such as a ditch, field
tile, pond or stream. An open loop system may require
periodic inspection/cleaning to prevent buildup of
mineral deposits.
Closed loop systems
The GeoExchange closed loop system is an underground network of sealed, high-strength
plastic pipe filled with a water/antifreeze solution. During cooling, heat is removed from the
building and dissipated into the cooler earth. For heating, low-intensity heat energy is absorbed
from the earth, intensified, and delivered into the structure. A closed loop system uses a small,
low-wattage pump to circulate the liquid. Closed loops can be installed in the ground horizontally
in a trench, vertically in drilled holes or submerged in a pond or lake. All three are sealed airtight
and, when designed properly, produce similar efficiencies.

Operating Procedures
To enjoy all the benefits of your Premier2
GeoExchange system, please review the following
operating procedures, service tips and information.
You’ll find your system easy to operate and simple to
maintain at its peak performance. However, if you have
any questions or problems, contact your local
WaterFurnace dealer.
What do I need
to know
about my
thermostat?
Your digital thermostat has
been designed to provide highly
accurate control of room
temperature. In addition, it will display information relating to your system’s operation. The
clearly marked buttons and informative display make it easy to understand and simple to use.
Note: WaterFurnace offers several different
thermostats that can be used with your Premier2
system. The instructions that follow apply only
to the type of thermostat pictured here. For
operating instructions of other thermostats,
contact your WaterFurnace dealer.
General information
The thermostat normally displays room temperature,
mode of operation selected and current system status.
The five buttons on the front allow complete control of the
system.
You may select different heating and cooling setpoints for
the system to maintain, e.g. 70
o
F in heating and 75
o
F in cooling.
Raising and lowering the setpoints in heating or cooling is as simple as pushing a button.
In addition, your WaterFurnace dealer can configure the thermostat for either
o
F or
o
C
on the display.

Important: Always allow the system at least five minutes to
respond to any changes in settings. The thermostat has been pro-
grammed to start the heating or cooling cycle in
stages.
Note: The electronic thermostat cannot be
set closer than 3obetween heating and
cooling.
How do I set my
thermostat?
Mode button
Push and release the MODE button to select the desired
mode of operation. Each time the
MODE button is pushed and released, the thermostat will
select a different mode. The different modes are as follows (in sequence):
OFF System will not operate
COOL Cooling operation only
HEAT Heating operation only
AUTO Heating or cooling operation
E HEAT Heating with auxiliary heat only
Heat
Push and release the MODE button until the display
reads
HEAT . Your system is now in the heating mode.
To review the heating setpoint, momentarily press either
the or button and you will see your current
setpoint displayed along with the words
DESIRED TEMP
illuminated on the display. The display will read HEAT and ENERGY SAVINGS when
the system is operating in either the first or second stage heating mode. The heating cycle
starts with the fan and compressor on a lower speed. (For single-speed units there is only one
compressor speed.) This lower fan speed reduces the sound level and increases air tempera-
ture. Note: It is normal for the Premier two-speed GeoExchange system to have extended run
times in low speed. The Premier two-speed is the most efficient in low speed operation. Should
the thermostat require maximum heat, the fan and compressor will switch to a higher speed.
(For single-speed units there is only one compressor speed.) During extreme cold weather,
additional heating capacity may be required. At such times, the thermostat will automatically
request auxiliary heating assistance, and display the words
AUX HT . The ENERGY
SAVINGS on the display is not illuminated when auxiliary heat is being used.

9
Premier2 Owner’s Manual
Note: If your system is not equipped with auxiliary heat, the
thermostat may still indicate a request for auxiliary heat.
At the end of the heating cycle, the fan will remain on for
approximately 30 seconds, unless “Continuous Fan” has been
selected.
Cool
Push and release the MODE button until the display
reads
COOL . Your system is now in the cooling mode.
To review the cooling setpoint, momentarily press

DESIRED TEMP will be displayed.
The words
COOL and ENERGY SAVINGS will be displayed when the system is
operating in the cooling mode. The cooling cycle starts with the fan and compressor on a
lower speed. (For single-speed units there is only one compressor speed.) This lower
speed increases humidity removal and reduces sound levels. Note: It is normal for the
Premier two-speed GeoExchange system to have extended run times in low speed. The
Premier two-speed is most efficient in low speed operation. Should the thermostat require
maximum cooling capacity, the fan and compressor will switch to a higher speed. (For
single-speed units there is only one compressor speed.)
At the end of the cooling cycle, the fan will remain on for approximately 30 seconds,
unless “Continuous Fan” has been selected.
Auto
Push and release the MODE button until the display
reads
AUTO . Your system is now in the automatic
mode, with either heating or cooling operation available.
To review the heating and cooling setpoints,
momentarily press either the or button. The
thermostat will then either display the current heating
setpoint and the word HEAT , or the cooling setpoint and
the word
COOL . If the heating setpoint and the word HEAT
is displayed, pressing the MODE button within five seconds will
display the cooling setpoint and the word
COOL . If the cooling setpoint and the word
COOL is displayed, pressing the MODE button within five seconds will display the heating
setpoint and the word

used if your Premier2 unit is inoperable. Note: If your
system is not equipped with auxiliary heat, do not select the emer-
gency heat mode.
Off
Push and release the MODE button until the display reads OFF . When the word OFF is
displayed the system will not provide heating or cooling.
The display still shows room temperature
and the fan is operable. Avoid using the
OFF mode during extremely cold weather
to prevent damage to your home from freezing.
How do I set
the fan?
Fan button
To select continuous fan operation, press
and release the FAN button and the display
will show the words
FAN ON . Continuous
fan operation uses low speed to quietly
circulate the air in your home or building.
Continuous fan operation is useful when using an air cleaner for continuous air filtering or
to help maintain even air temperatures throughout a multilevel or large home or building. The
fan will come on automatically whenever the system is operating, but there will be no indica-
tion of this on the thermostat display.

What if the word TROUBLE is
displayed on the thermostat?
The TROUBLE display is used to indicate the following
problems:
Continuously on
TROUBLE with backlight for LCD
flashing—the system has shut down due to a protective
device (see resetting the unit section, page 15). The
auxiliary heat, if installed, will automatically come on if
necessary to keep the home or building comfortable.
Slow flashing
TROUBLE (about 1 flash/second) with
backlight for LCD flashing—the unit is not receiving valid
thermostat signals. Your unit will operate normally during this
time if possible. Call your WaterFurnace dealer.
Fast flashing
TROUBLE (about 3 flashes/second)—The unit is locked-out due to
insufficient airflow. Check, clean or replace filter. Reset the unit (see page 15). If unit still
does not operate or the TROUBLE display is still on, call your WaterFurnace dealer.
What if the words CLEAN
FILTER are displayed on the
thermostat?
This indicates that it is time to replace or clean the air
filter in the system.
After a new (or clean) filter is in place, press the
RESET FILTER button to reset the timer.
What do I do in case
of a power failure?
Don’t worry. Your Premier2 thermostat employs the latest developments in solid-state
electronic technology. One of its unique features is the elimination of the battery required to
maintain your selected set points in the event of a power loss. The thermostat memory is
unaffected by power failures of any duration. When power is restored, the thermostat will
continue operating as if the power had never been interrupted. However, there will be no
heating or cooling during the outage.

Premier2 Owner’s Manual
What if my unit stops working?
Your Premier2 unit has been equipped with a battery of self-protection devices and
controls. Should you suspect that heating or cooling operation has ceased, look at the
thermostat to see if the word
TROUBLE is displayed.
• If it is on continuously or flashing rapidly, see resetting the unit section, page 15.
• If it is flashing slowly, operation may seem normal but there is a problem. Call your
WaterFurnace dealer for assistance.

What do I need to know about the
unit itself?
Your Premier2 unit is equipped with a variety of information and warning lights known as
STATUS lights. These lights are mounted in plain view on the front left corner of your unit.
They will help you properly identify any problems and what might be required to correct the
situation.
These lights will:
• help determine whether your system is operating correctly

13
Premier2 Owner’s Manual
• help identify any problems
• help determine if you can fix the problem
yourself and avoid a service call
• save you time and expense when you need
to call an independent WaterFurnace
dealer by helping them identify the
problem before they come out.
Status light descriptions
and service tips
Drain
When this light comes on, it indicates that the condensate drain pan within the unit has
reached the overflow level. This may be caused by foreign matter blocking the drain pan
opening. See Drain Pan under the “How do I maintain my system?” section on page 14 for
service tips.
Water Flow
A sensor protects your unit against internal freeze up caused by a water flow loss in the
heating mode. When the WATER FLOW light is on, this signals that internal freezing
conditions have occurred. This may be caused by a pump failure, low antifreeze level or air
pockets in the loop piping (see resetting the unit section, page 15).
Low Pressure
When this light is on it indicates a loss in refrigerant pressure in the system. This may be
caused by a refrigerant leak (see resetting the unit section, page 15). This could also be a
signal of low pressure in cooling, due to a dirty filter.
High Pressure
When this light is on it indicates high refrigerant pressure. This may be caused by a loss of
water flow in the cooling mode or low airflow in the heating mode. This could also be a signal
of high pressure in heating, due to a dirty filter.
Airflow
When this light is on it indicates an airflow problem. Contact your WaterFurnace dealer.
Status
A blinking STATUS light indicates that the microprocessor control, which is the “brain” of
the unit, is operating properly. If the light doesn’t flash but remains continuously on or off, the
Status Lights

14
Premier2 Owner’s Manual
control is inoperative. Turn off all power to the unit, including auxiliary heat, and then turn it
back on. If the light remains continuously on or off call your WaterFurnace dealer.
DHW Limit
A sensor monitors the temperature of your hot water tank. The light will come on if the
temperature is above 130°F (54°C). At this time your unit’s hot water system will be de-
energized to prevent excessive temperatures. Don’t worry; hot water operation will resume
when the tank cools off. This is not a fault condition, and the unit does not require resetting.
DHW Pump Switch
When the pump switch is off, your unit’s hot water system is disabled, and DHW OFF
status light will be lit. This switch may be used when the water heater is being serviced or
replaced. This switch must be turned off when water flow from the water heater to the
Premier2 unit is turned off or disconnected. Damage to the pump may otherwise occur.
What kind of safety controls does my
unit have?
Your WaterFurnace Premier2 unit is equipped with safety controls which are designed to
protect the unit in case of improper airflow, water flow or refrigerant charge. These safety
controls should not be bypassed by anyone. Doing so may void the warranty.
How do I maintain my system?
Caution: Before you perform any maintenance to your system,
turn off all electrical power to the unit. There may be separate
supplies— one for the unit and one or two for the auxiliary heat.
Filters
• Check your filters every 60 days. A dirty filter will cause your unit to work harder than
necessary, waste energy and may cause premature component failure.
• To achieve optimum performance and economical operation, change your “replaceable
type” filter if you see a buildup of dust or dirt.
• If you have opted for a permanent electrostatic filter, wash it with a garden hose at least
every 60 days. When placing the filter back in the slot, be sure that the arrow on the
filter frame points toward the Premier2 unit.
• After a new or clean filter is in place, press the
RESET FILTER key on the thermostat.
• Never operate the unit without a filter; this will void the warranty.

Premier2 Owner’s Manual
Water Supply for Well Water Systems
An adequate water supply to the unit is very important. Do not let anyone disrupt the water
supply by rerouting the supply line or tapping into it without first checking with your
WaterFurnace dealer. If the well pumping system requires service or is inoperable, your unit
should be turned off until an adequate water supply is restored.
Water Supply For Closed Loop Systems
No regular maintenance is required. However, if you notice air noise within the piping or
your loop is ever damaged by excavation, contact your WaterFurnace dealer.
Drain Pan
• In the cooling mode, moisture removed from the air forms as condensation on the air
coil and the resulting water runs down to the condensate drain pan. The drain can pick
up lint and dirt, especially with dirty air filters. If overflow occurs, the
DRAIN light will
come on and the system will shut down.
• If the water does not run freely, clean the drain pipe. Pour a capful of bleach in the
drain pan once a year. This helps to prevent algae.
• To gain access to the drain pan for inspection: Turn off all power to unit and auxiliary
heat. Remove the screw located above the top center of the fan compartment door.
Lift the door up and pull out at the bottom. The drain pan is the black plastic or metal
rectangular pan with the drain hole in the middle.
What about regular service?
Your Premier2 system requires no regular maintenance. However, once a year or so, have
the unit inspected by an independent WaterFurnace dealer. They will check the unit’s perfor-
mance and make sure that your Premier2 unit is heating and cooling at its peak performance
level. If your unit is using a well as its water supply, your unit may need periodic cleaning to
remove mineral deposits.
If my unit shuts off, how do I reset it?
To reset the unit, repeatedly push the MODE button on the thermostat until the display
reads
OFF .
• If FAN ON is displayed, it must also be turned off by pushing the FAN button.
• The TROUBLE signal will continue flashing or remain on for up to 60 seconds after
turning the system and fan off.
• After the TROUBLE signal goes out, turn the system back on to the desired
MODE and re-select FAN ON if desired.
• Unit operation should resume within five minutes if heating or cooling is required.

16
Premier2 Owner’s Manual
• The appropriate status light on the Premier2 unit will continue indicating the fault until
power is interrupted to the unit. This serves as a diagnostic aid for your dealer.
• If the unit shuts down again, call your WaterFurnace dealer as soon as possible. Do not
repeatedly reset your unit.
What if my unit does not operate properly?
Before you call your WaterFurnace dealer for service, check these service hints:
•
Check air filters. Depending upon filter type, clean or replace if necessary. (See Filters,
page 14.)
• Make sure the thermostat is set properly.
• Check to make sure the electrical disconnect switches are in the
ON position. Both the
unit and auxiliary heat (if present) must be powered for proper operation.
• Check for a tripped circuit breaker or a blown fuse in your home or building’s main
power box. Reset breaker or replace fuse.
• If either the disconnect switch or the circuit breaker continues to go off after you reset
them, call your WaterFurnace dealer immediately to prevent damage to your unit.
• Check the thermostat indicator lights to ensure proper operation of the system.
• Check the unit status lights on the corner of the unit to ensure the unit is operating
properly.
• If you can’t determine the problem, call your WaterFurnace dealer promptly.
