UNIT FEATURES
This unit 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.
• SELF DIAGNOSITICS—The unit has an onboard computer that utilizes real-
time diagnostics to prolong the life of your unit. There is an LED indicator on
the control board located behind the front panel, that will ash an error code
if the unit has detected some kind 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
Table 6—Status LED Indicator Denitions for further details.
• AUTO RESTART—If power is lost, all of the control settings (setpoint, mode,
fan speed, on/off and conguration) are stored. So when power is restored, the unit will start back up in the mode (and conguration) it was in when power was lost.
• QUIET OPERATION—The unit has 2 fan motors and a tangential blower wheel to reduce noise. 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 PTAC/HPs starting
at the same time), the compressor is equipped with a 2:45 to 3:15 minute random restart delay feature.Whenever the unit is
plugged in, or power has been restarted, a random compressor restart will occur between the random restart time frame.
• COMPRESSOR PROTECTION—To prevent short cycling of the compressor and maximize it’s life, there is a random start--up
delay of 3 minutes on the compressor and a minimum compressor run time of 3 minutes.
•AUTOMATIC ROOM FREEZE PROTECTION—The unit will automatically will keep the temperature in the room from getting
too cold, where water pipes might freeze. If the unit is congured for the freeze protection feature to be active (which is the
default condition), and while power is supplied to the unit, if the unit senses temperature below 40°F, the fan motor and
electric heater are turned on and will warm the room to 50°F. If Freeze protection is not required, change the conguration
switch to turn the feature off (see section on unit conguration).
• AUTOMATIC DEFROST PROTECTION (FOR HEAT PUMP MODELS ONLY)—When the outdoor temperature gets too cold (ap-
prox. 35°F) 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 (approx. 40°F), so the compressor
can be used to effectively heat again.
• AUTOMATIC QUICK WARM-UP (FOR HEAT PUMP MODELS ONLY)—If the room temperature falls to 5°F 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 satised.
•LED INDICATOR’S 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 which operating mode is active. The LEDs below the Fan button,
Low, Med and Hi, 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.
• CONFIGURE FAN TO OPTIMIZE SELECTED APPLICATION—This unit can be optimized to specic applications by conguring
the fan to run in a continuous mode or to cycle on and off with the compressor and electric heater (can be different for both
heating and cooling modes). In cycle mode, fan will continue to run after compressor or electric heater stops in order blow off
any residual heat or cool left on coil. In continues mode, the fan remains on at all times even when the compressor is off.

• Unit Conguration —There are many different conguration possibilities, through both dipswitches and the digital keypad,
that allow you to congure the unit for your exact application. See section on unit conguration for more details. Following
are the conguration selections that have not previously been mentioned:
• °F or °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).
• Emergency Heat (forHeat Pump Only)—Disable the compressor during heating mode operation (heat
only with Electric Heat).
• Display Setpoint OR Room Temperature—The unit can be congured to display the room temperature
OR setpoint only, during heating and cooling modes. See section on unit conguration for more details.
• Limit the Setpoint Range—The unit can be congured to limit the controlling setpoint range.The display
will always show the complete setpoint range, but the controlling setpoint will be limited to the congured
minimum and maximum setpoint selected. See section on unit conguration 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 24 vac 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
congured to disable the keypad. See section on wired inputs and unit conguration for more details.

base pan periodically and clean, if necessary.
AIR FILTERS
IMPORTANT: TURN UNIT OFF BEFORE CLEANING
Airow restriction may cause damage to the unit.
CAUTION
!
UNIT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
Do not operate unit without lters in place. If a lter becomes torn or damaged, it should be replaced immediately.
Operating without lters in place or with damaged lters will allow dirt and dust to reach indoor coil and reduce
cooling, heating, airow and efciency of unit. Airow restriction may cause damage to unit.
Themost important thing you can do to maintain unit efciency is to clean the lters at least every 30 days (or sooner depending
on application). Clogged lters reduce cooling, heating and airow.
Keeping lters clean will:
• Decrease cost of operation.
• Save energy.
• Prevent clogging the indoor coil.
• Reduce risk of premature component failure.
To Clean Air Filters:
• Vacuum off heavy soil.
• Run water through lters.
• Air dry thoroughly before replacing.
