UNIT FEATURES

This unit has many exciting features which are different from 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 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 kind of faulty 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 5 (page12) - Status LED Indicator Definitions for further details.
• Memory -- Your 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.
• Quiet Design -- Not only does the unit 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 the sound of the compressor starting.
• Random Compressor Restart -- To help prevent power surges after a power outage (many PTACs starting at the same time), the compressor is equipped with a 2 minute 45 second to 3 minute 15 second random restart delay feature. Whenever the unit is plugged in, or power has been restarted, a random compressor restart will occur to help avoid power surges. 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 -- This protection feature will automatically ensure the indoor temperature does not fall below freezing. When your PTAC is configured for freeze protection (which is the default condition), then whenever 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. Freeze protection can be switched off (please see page 9), change the configuration switch to turn the feature off (see section on unit configuration).
• 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 room temperature rises.
• Dual-8 Display and LED Display -- Two 8-segment nixie tubes, 13 LED indicators (They are HIGH, MED, LOW, AUTO, COOL, FAN, HEAT, ON/OFF, SETOPINT, INDOOR, STATUS and TIMER)
  1. Mode indicator display: When the air conditioner operates in a certain mode, the corresponding mode indicator will be lit;
  2. The ON/OFF indicator is in green when the controller is ON and in red when controller is OFF.
  3. Fan speed display: When air conditioner operates at high, medium, low or auto fan speed, the corresponding indicator will be lit.
  4. Dual-8 display: Ambient temperature can also be displayed in cooling and heating modes through setting the keypad. Under cooling or heating mode, the dual-8 will display the set temperature (the dual-8 will display indoor ambient temperature under fan mode).
  5. If the display data has three bits, the dual-8 will display “ten's digit”+ “unit's digit” at first and then display “BLANK”+ “hundred's digit”
• Fan Configure for Optimization of Selected Application -- The unit can be optimized to selected application by configuring the fan to run in continuous mode or cycle on and off with the compressor and electric heater (can be different for both heating and cooling modes). In cycle mode, the fan will continue to run after the compressor or electric heater stops in order to blow off any residual heat or cool left on coil.

SYSTEM CONFIGURATION

VENTILATION CONTROL

• The ventilation control lever is located at left side of unit, behind the front panel.

NOTE: The vent door shipping screw must be removed before using vent control lever. See Installation Instructions.

• When set at CLOSE, only the air inside the room is circulated and filtered. When set at OPEN, outdoor air will be drawn into room.
• Energy Tip: Keep the vent control at CLOSE. Room air will be filtered and circulated.

ADJUSTING AIR DIRECTION FOR DUCTED INSTALLATIONS ONLY

To adjust air direction:

If Low fan is desired, wire the GL output from the thermostat to GL on the unit's terminal block. If Hi fan is desired, wire the GH output from the thermostat to GH on the unit's terminal block.

NOTE: After proper installation, if your thermostat is not working properly, refer to the Trouble Shooting section on page 17.

TERMINAL CONNECTIONS

The wall thermostat terminal block is located behind the front panel and is easily accessible on front of control panel.

NOTES

1. Use terminal “O” for heat pump connection only.
2. Terminal “C” (common) is typically only required for digital thermostats.

ENERGY MANAGEMENT INPUT (FRONT DESK CONTROL)

• The controller can handle a switch signal from remote energy management input, called EM signal or front desk control. Input must be 24VAC. If system receives a 24VAC signal, it will turn unit off; otherwise, the unit runs in normal control. This function will be disabled under Freeze Guard protection. See Fig. 20 and Fig. 21 for terminal connections.

INTELLIGENT SELF-CHECKING CONTROL

• Your Frigidaire PTAC 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 a minor error and the unit can correct it 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.23). Failure STATUS codes are defined in the table below

CARE AND CLEANING

FRONT PANEL AND CASE

• Turn unit off and disconnect power supply. To clean, use water and a mild detergent. DO NOT use bleach or abrasives. Some commercial cleaners may damage the plastic parts.

OUTDOOR COIL

• Coil on outdoor side of unit should be checked regularly. Unit will need to be removed from its sleeve to inspect dirt build-up that can occur inside of the coil. If clogged with dirt or soot, coil should be professionally cleaned.

NOTE: Never use a high - pressure spray on coil.

CAUTION - UNIT DAMAGE HAZARD: Product failure due to improper care or lack of maintenance is not covered by warranty. Airflow restriction may cause damage to the unit.

BASE PAN

• Check base pan periodically and clean, if necessary.

AIR FILTERS

IMPORTANT: TURN UNIT OFF BEFORE CLEANING

CAUTION - UNIT DAMAGE HAZARD: Product failure due to improper care or lack of maintenance is not covered by warranty. Do not operate unit without filters in place. If a filter becomes torn or damaged, it should be replaced immediately. Operating without filters in place or with damaged filters will allow dirt and dust to reach indoor coil and reduce cooling, heating, airflow and efficiency of unit. Airflow restriction may cause damage to unit.

To maintain unit efficiency clean the filters at least every 30 days (or sooner depending on application). Clogged filters reduce cooling, heating and airflow.

Keeping filters clean will:

• Decrease cost of operation.
• Save energy.
• Prevent clogged indoor coil.
• Reduce risk of premature component failure.

To Clean Air Filters:

• Vacuum off heavy soil.
• Run water through filters.
• Dry thoroughly before replacing.
