UNIT FEATURES
This ETAC II has many exciting features which are different than those found on standard PTAC
models. The owner must be familiar with these features in order to fully understand the operation
and capability of the unit.
• Intelligence – Your ETAC II unit has an on board computer that utilizes real time diagnostics
to prolong the life of your unit. There is an LED indicator on the control board, behind the front
panel, that will flash an error code if the unit has detected some type of fault condition. In
many cases, the unit will automatically clear the fault condition and continue operating with
no interruption. In some cases, the condition cannot be cleared and the unit will require service.
In those cases, an “Fx” failure mode will be displayed on the digital display. For a detailed list
of all error codes and “Fx” conditions, see Intelligent Self Checking and Control section on page
20 for further details.
• Memory – Your ETAC II unit also has memory. If power is lost, all of the control settings (setpoint, mode, fan speed, on/off and configuration) are remembered. So when power is restored,
the unit will start back up in the mode (and configuration) it was in, when power was lost.
• Premium Sound – Your Premium ETAC II is also the quietest Gree PTAC. Not only does it have
2 fan motors and a tangential blower wheel for optimum sound, the indoor fan will always run
a minimum of 10 seconds before the compressor, to help reduce any compressor starting noise.
• Random Compressor Restart – To help prevent power surges after a power outage (from
many of your ETAC IIs starting at the same time), the compressor is equipped with a 165 to
195 second random restart delay feature. Whenever the unit is plugged in, or power has been
restarted, a random compressor restart will occur.
• Dry Mode – will help to manage and reduce the humidity in the room, making it more
comfortable. In DRY mode, the unit will modulate cooling mode at low fan speed until the
room temperature is 4 deg. F below the room temperature setting regardless of fan mode
selection. Dry mode should not be considered a substitute for a stand alone dehumidifier.
• Compressor Protection – To prevent short cycling of the compressor and maximize its life,
there is a 3 minute start-up delay on the compressor after power up and between operating
cycles and a minimum compressor run time of 3 minutes.

UNIT FEATURES
• Unit Configuration – There are many different configuration possibilities, through both dip
switches and the digital keypad, that allow you to configure the unit for your exact application.
See section on unit configuration for more details. The following are the configuration selections
that have not previously been mentioned:
• Fahrenheit °F or Celsius °C – The unit can display in either °F or °C.
• Indoor Temperature Sensor Biasing – Optimize the room temperature sensor reading
to your exact application (one for cooling and another for heating).
• Display Setpoint or Room Temperature – The unit can be configured to display the
room temperature OR setpoint only, during heating and cooling modes. See section on
unit configuration for more details.
• Emergency Heat (for Heat Pump Only) – In the event the compressor becomes non-operational, it can be disabled during heating mode allowing heating with the electric heater only.
• Limit the Setpoint Range – The unit can be configured to limit the controlling setpoint
range. The display will always show the complete setpoint range, but the controlling
setpoint will be limited to the configured minimum and maximum setpoints selected.
See section on unit configuration for more details.
• Energy Management – Sometimes known as Front Desk Control, an input is provided so
that the unit can be manually disabled from a different location. If the unit detects 24vac
on this input, it will automatically turn itself off. If no voltage is detected on the input, the
unit will run normally.
• Wall Thermostat Control – A wired wall thermostat can be connected to the unit. If it is,
the unit must be configured to disable the keypad. See section on wired inputs and unit
configuration for more details.
• Automatic Quick Warm-up (for heat pump models only) – If the room temperature falls to
5°F (2.8°C) below the set point temperature, the reverse cycle heat is shut off and the electric
strip heat is turned on for one cycle, until heating is satisfied. Then it reverts back to heat pump.
• Automatic defrost protection (for heat pump models only) – When the outdoor temperature
gets too cold and the unit can no longer effectively heat with the compressor, the unit will
automatically switch to electric heating. The unit will then heat with electric heat until the outside temperature rises enough to defrost the outdoor coil, so the compressor can be used again.
• Automatic room freeze protection – When the room is unoccupied for long periods during the
colder months, the unit will automatically keep the room between 40°F (4.4°C) and 50°F (10°C).
Room freeze protection can be disabled by unit configuration dip switches. See System
Configuration section for more information.

UNIT FEATURES
• LED Indicators and Buttons – The touch pad has buttons for MODE, FAN SPEED, ON/OFF,
SETPOINT UP and SETPOINT DOWN. It also has LEDs that correspond to the mode, fan speed
and setpoint operation, to indicate the unit’s status. The LEDs below the mode button, FAN,
COOL, and HEAT, indicate what operating mode is active. The LEDs below the Fan button, Low,
Hi and Auto, indicate the fan speed that is selected. The LED located in the lower right corner is
the unit On/Off status LED. If the unit is in ON mode, the LED will be green. If the unit is OFF,
the LED will be red.
• Configurable Indoor Fan – The indoor fan can be configured to run in continuous mode or
cycle on and off with the compressor and electric heater (this function can be different for
both heating and cooling modes). In cycle mode, fan will continue to run 60 seconds after
compressor or electric heater stops to remove residual heat and cool off of the coil.
CONDENSATE REMOVAL SYSTEM
ETAC II has a new condensate (water) disposal
system. The outdoor fan prop has a built in slinger
ring which draws condensate water and sprays
it on the warm outdoor coil for evaporation. Thus
providing better disposal of excess condensate and
improving unit operating efficiency.
It is normal and desirable to have some condensate
water in the base pan to boost operating efficiency.
Fig. 2
All heat pump units contain a condensate drain valve. This temperature activated drain valve opens
when the outdoor temperature drops below 55°F (12.8°C) to prevent water from freezing in the
base pan. The water drains from the unit though the wall sleeve and out the wall sleeve’s rear
condensate drainage holes. If the condensate drain kit accessory is attached to the wall sleeve,
water will drain through the condensate drain tube.
NOTE: This unit will not always evaporate 100% of the unit generated condensate and
blown in rain water. If it is necessary to control 100% of the condensate, the Drain Kit
(Part No.: DRAIN-KIT-1PK) and a building condensate drain system is recommended.

CAUTION
PROPER INSTALLATION IS THE RESPONSIBILITY OF THE INSTALLER. Product failure
due to improper installation is not covered under the limited Product Warranty.
CHASSIS INSTALLATION
Units are shipped without a sleeve. In applications where unit is a replacement, it is recommended
that a standard wall sleeve be used.
These units can retrofit Carrier, General Electric, Amana, Trane, and Friedrich sleeves/grilles (be sure
outdoor grille is installed on the sleeve). See Table 3 for details. Gree engineering must approve any
other retrofit application.
For competitive retrofit applications, be sure that the foam seals (factory-installed on the tube
sheets) provide a good seal between the grille and outdoor coil. These foam seals provide
a barrier to separate outdoor coil discharge air from mixing with the outdoor
incoming air (known as air recirculation). Baffles may be required when using

WINDOW WALL INSTALLATIONS
This application has become more common due to pre-manufactured windows with built-in
grilles. Installations using a grille built in a pre-manufactured window assembly may require
installation of an Accessory Baffle Kit (see Fig. 5), which ensures a good air seal between the
outdoor coil and exterior grille to prevent air recirculation. Air recirculation is a large contributor
to capacity loss and premature damage to major components.

SYSTEM CONFIGURATION
WALL THERMOSTAT INSTALLATION (CON’T)
7. Connect thermostat wire to the ETAC II thermostat connection terminals per wire diagram (see Fig. 22).
NOTES:
1. Use terminal “O” for heat pump connection only.
2. Terminal “C” (common) is typically only required
for digital thermostats.
NOTES:
Any illegal input combinations will be captured as thermostat
wiring failures and will light the STATUS LED indicator on main
board (see Intelligent Self-Checking Control section).
Fig. 22 – Wiring Connections
NOTE: For thermostats that have only one fan speed output (on or auto), the fan speed
is determined by how the terminal connector is wired. If Low fan is desired, wire the
G output from the thermostat to GL on the unit’s terminal block. If Hi fan is desired, wire
the G output from the thermostat to GH on the unit’s terminal block.
8. Carefully re-attach thermostat terminal block on unit.
9. Locate configuration dip switches above thermostat
terminal connections. Set switch #2 "UP" for Wall
Thermostat Mode (see Fig. 17).
10. Install thermostat escutcheon label over touchpad
control panel (see Fig. 23). Included in I/O packet.
11. Mount, wire and configure wall thermostat
per instructions provided by the manufacturer.

SYSTEM CONFIGURATION
ENERGY MANAGEMENT INPUT (FRONT DESK CONTROL)
The ETAC II can interface to a switch signal from remote energy management input, called EM
signal or front desk control. The input signal must be 24 VAC. If unit receives a 24 VAC signal, it
will turn off; otherwise, the unit runs normally. This function will be disabled under Freeze Guard
protection. See Fig. 21 for terminal connections.
INTELLIGENT SELF-CHECKING CONTROL
Your ETAC II has a computer on board that continuously checks key components of the unit to
ensure they are operating properly. Under normal operation, unit status indicator (STATUS, on
main PCB), light is steadily ON. If there is a major problem, the unit will shut down and display
a diagnostic failure code on the unit’s display. If it is only a minor failure and unit is correcting the
fault by itself, the diagnostic code will be flashed on the status LED that can easily be seen when
the front panel is removed (see Fig. 21). Failure STATUS codes are defined in the table below.

TROUBLESHOOTING
POSSIBLE CAUSES
UNIT DOES NOT START
• Unit may have become unplugged
• Fuse may have blown
• Circuit breaker may have been tripped
• Unit may be off or in wall thermostat mode. Check
section on dip switch settings to verify dip switches
are set properly.
• Unit may be in a protection or diagnostic failure mode.
See section on Intelligent Self-checking Control.
UNIT NOT COOLING/HEATING ROOM
• Unit air discharge section is blocked
• Temperature setting is not high or low enough.
Note: Setpoint limits may not allow the unit to
heat or cool the room to the temperature desired.
Check section on dip switch settings.
• Unit air filters are dirty.
• Room is excessively hot or cold when unit is started.
• Vent door left open
• Unit may be in a protection or diagnostic failure
mode. Check section on Intelligent Self-checking
Control.
• Compressor is in time delay. There is a protective time
delay (approx. 3 minutes) on starting the compressor
after a power outage (or restarting after it has been
turned off), to prevent tripping of the compressor
overload.
SOLUTIONS
• Check that plug is plugged securely in wall receptacle.
Note: Plug has a test/reset button on it. Make sure that
the plug has not tripped.
• Replace the fuse. See Note 1.
• Reset circuit breaker. See Note 1.
• Turn unit on (bottom right button on keypad).
Note: If the unit turns on, the LED will be green. If the
unit is off, the LED will be red. If there is no LED on, there
is a problem with power or damage to the control.
• Make sure that curtains, blinds or furniture are not
restricting or blocking unit airflow.
• Reset to a lower or higher temperature setting.
• Remove and clean filters.
• Allow sufficient amount of time for unit to heat or
cool the room. Start heating or cooling early before
outdoor temperature or gatherings of people make
room uncomfortable.
• Close vent door.
• Check dip switch settings for desired comfort.
Wait approximately 3 minutes for compressor to start.
DISPLAY HAS STRANGE
NUMBERS/CHARACTERS ON IT
• The unit may be in a diagnostic condition. Check
Intelligent Self Checking Control section to determine
if unit has had a failure.
• The unit may be set for °C (instead of °F), see the
keypad configuration section.
UNIT MAKING NOISES
• Clicking, gurgling and whooshing noises are normal
during operation of unit.

TROUBLESHOOTING
POSSIBLE CAUSES
SOLUTIONS
WATER DRIPPING INSIDE
• Wall sleeve is not installed level
• Clogged drain
• Wall sleeve must be installed with a 1/4 bubble pitch
toward the outside for proper drainage of condensation.
Check that installation is level and make any necessary
adjustments.
• The condensate drain may be partially or fully plugged.
ICE OR FROST FORMS ON INDOOR COIL
• Low outdoor temperature
• Dirty filters
• When outdoor temperature is approximately 55°F
(12.8°C) or below, frost may form on the indoor coil
when unit is in Cooling mode. Switch unit to FAN
operation until ice or frost melts.
• Remove and clean filters.
COMPRESSOR PROTECTION
• Power may have cycled, so compressor is in a restart
protection.
• Random Compressor restart – Whenever the unit
is plugged in, or power has been restarted, a random
compressor restart will occur. After a power outage, the
compressor will restart after approximately 3 minutes.
• Compressor Protection – To prevent short cycling
of the compressor, there is a random start up delay
of 3 minutes and a minimum compressor run time of
3 minutes.
WALL THERMOSTAT PROBLEM
• Verify wiring is correct between thermostat and unit.
• Dip Switch settings are only read during power up.
Unplug unit and verify Dip Switch Settings, then plug
unit in.
NOTES:
1. If circuit breaker is tripped or fuse is blown more than once, contact a qualified electrician.
2. If unit is installed where condensation drainage could drip in an undesirable location, an accessory drain kit should be installed
and connected to drain system.

IF YOUR AIR CONDITIONER DOES NOT WORK, FOLLOW THESE STEPS IN ORDER:
1. CHECK THE THINGS YOU CAN DO YOURSELF. These include being sure the air conditioner is plugged in firmly in an appropriate receptacle, checking the fuse
or circuit breaker and ensuring its replacement or resetting, if necessary, and rereading the instruction book to ensure that all controls are set properly. By doing
this you can save money. Many unnecessary service calls result in the serviceman doing what the owner can do for him or herself.
2. CONTACT YOUR DEALER OR THE AUTHORIZED SERVICE CENTER HE RECOMMENDS. They have been set up to handle the great majority of all possible service
problems. The quickest, surest and best way to get your air conditioner back in service is to use this step before proceeding further.
