UNIT FEATURES

This unit has many features which are different than those found on conventional PTAC units. The servicer must be familiar with these features in order to properly service the unit.

• LCDI or AFCI Power Cords - Underwriters Laboratories and the National Electric Code (NEC) now require power cords that sense current leakage and can open the electrical circuit to the unit on units rated at 250 volts or less. In the event that unit does not operate, check the reset button located on or near the head of the power cord as part of the normal troubleshooting procedure.

LCDI power Cord

• Automatic 3-minute compressor lockout - After the compressor cycles off, it will not restart for three minutes.

• Automatic 2 nd stage electric heat - If the room temperature falls to 4°F below the set point temperature, the reverse cycle heat is shut off and the electric strip heat is turned on.

2

• Automatic freeze protection - Whenever power is supplied to the unit and the master switch is in the ON position, automatic freeze protection is active. If the unit senses temperature below 40°F, the fan motor and electric strip heat are turned on. Freeze protection can be turned off, if required.

• Random restart delay - To help eliminate power surges after a power outage, the unit is equipped with a two to four minute random restart delay feature. Whenever the unit is plugged in with the master switch turned on and the mode switch set in the cool or heat mode, a random restart will occur. A random restart condition can be avoided by setting the mode switch in the fan only or off position before applying power to the unit.

• Fuse holder - On all 265 volt units, fuse holders are factory installed. Check for blown fuse if unit does not operate. Fuse holder is located behind the front. Replacement fuses may be purchased from the Parts Department or contact your sales representative for part numbers.

7 Button Touch Pad With Display

• Load shedding - An LS terminal has been added for load shedding operations. If at any time a switch is closed between the LS and IN terminals, the compressor and electric heater will lockout until the switch is opened.

• Transfer fan - Terminals TF(-) and TF(+) on the low voltage terminal board allow for an external (transfer) fan connection. A user-supplied relay is required and, depending upon the type used, an approved external transformer kit may be required for installation.

NOTE: The PTAC Wire Harness Kit (PWHK01C) is required when using either the transfer fan or load shedding option.

FUSE

HOLDERS

• Front mounting hole - A mounting hole location is provided to give the owner the option of securing the front to the chassis. The mounting hole must be drilled at the dimple indicating the correct location below a louver. The owner must supply one 1/2 inch long #8 sheet metal screw per unit. The screw must be removed before the front can be removed.

Control Panel

• Indication LEDs - The touch pad has LEDs that correspond to fan operation and to indicate unit status. The LEDs next to the selections OFF, COOL, and HEAT indicate which operational mode is active. The LED located in the lower left corner is a status LED. This LED indicates the status of the unit. See Diagnostic Maintenance & Status Report section for further details.

• Energy Management System Features

Temperature Setback - This option can save energy dollars for unrented or unoccupied rooms by automatically setting back the operational temperatures. This mode of operation is selected through the configuration routine

(see Configuration Settings section).

NOTE: Temperature setback does not work with a wired remote thermostat.

Door Switch and Motion Sensor Low Voltage Terminals (DS1,

DS2, MS1, MS2) - The door switch and motion sensor operate as a unit, the door switch terminals allows for wired connection of a door sensor to the control board. The motion sensor interprets any door movement as a signal of occupancy. If the switch between DS1 and DS2 is closed, the door control will interpret the room door as closed. If the switch between MS1 and MS2 terminals is opened (or closed if unit is configured for normally open) the control will interpret the action as a signal of occupancy. If thirty minutes pass without any door activity, Energy Management Temperature setback activates.

Serial Port Interfaces - Two serial ports located on the control board provide easy access for two-way communications to the control board from an optional RF antennae can be attached for wireless communications.

REMOTE CONTROL INPUTS

The C, R, GL, W2, Y/W1, B/O, and GH terminals provide control inputs for a “manufacturer-approved” remote wall mounted thermostat. The “B” terminal can be configured to become “O” if needed see Configuration Settings For remote control thermostat operation, refer to the Remote Thermostat Operation section.

FRONT DESK CONTROL (FD1, FD2, EH, IN)

The FD1, FD2, EH and IN terminals provide control inputs for a front desk switch. Shorting across the FD1 and FD2 terminals will disable unit operation. The only control function which will remain active when these terminals are shorted is freeze protection. Any switch which will produce a short circuit across these two terminals can be used as a front desk switch. The contact resistance of the switch, when closed, must be less than 200 ohms for the front desk feature to operate properly. Table 3 shows the maximum wire length and corresponding gage size for installation of a front desk switch. The following figure shows a wiring schematic for connecting the front desk switch to the unit.

If the unit is configured for wired unrented setback energy management (see Configuration Settings section c2), EH and IN terminals are used instead of FD1 and FD2. If EH and IN are shorted, the unit will go into setback temperatures for cooling and heating as configured in c3 and c4 (see Configuration

Settings). Unit operation will be disabled. “Fd” (see Diagnostic

Codes) will appear on the display. This allows the room to quickly recover to a comfortable temperature when the room is occupied.

Do not install the thermostat where it may be affected by the following:

• Dead spots behind doors, in corners or under cabinets

• Hot or cold drafts from air ducts

• Radiant heat from the sun, appliances, or fireplaces

• Concealed pipes and chimneys

• Unheated (uncooled) areas behind the thermostat, such as an outside walls

Consult the instruction sheet packaged with the thermostat for further details on mounting and operation.

REMOTE THERMOSTAT OPERATION

Approved thermostats vary slightly in construction and, with few exceptions, are operated similarly. The following operational description pertains to approved nonprogrammable thermostats that energize G in Heat and Cool mode.

HEAT/OFF/COOL Switch

• OFF - cooling and heating functions are defeated.

• HEAT - the selected room temperature is maintained by cycling either in the heat pump mode or electric strip heat. A PTH unit is switched from the heat pump mode to electric strip heat when the coil temperature is 20°F or when the heat pump cannot keep up with the heating load and a two stage thermostat is used.

• COOL - the selected room temperature is maintained by cycling the air conditioner.

Table 4 summarizes the thermostat input combinations and the respective unit functions. The following wiring schematic illustrations show wiring schematics for heat pump and straight cool units with electric resistance heat, respectively.

ADDITIONAL NOTES:

1. For heat pump operation, a room thermostat with a B (heating change over) terminal or an O terminal (cooling change over) is required. This will mean that some “auto changeover” thermostats cannot be used, as many of them either do not have a B terminal, or else energize the B terminal continuously when in the “auto” position.

2. Additional wiring should be run for future changeover to Heat

Pump or thermostat options.

3. Run 6 to 8 wires during initial installation. Tape or cap off any unused wires.

NOTE: Using a thermostat with an O terminal will require that the 7 button with display control be configured (see Configuration Settings).

Cabinet Front

The cabinet front and discharge air grille can be cleaned with a water dampened cloth. Under no circumstances should hydro- carbon-based cleaners (e.g. acetone, benzene, naphtha gasoline, etc.) or ammonia based cleaners be used to clean the front or air grilles. Use care when cleaning the control area.

YEARLY MAINTENANCE AND CLEANING

NOTE: Use a mild biodegradable detergent such as Simple

Green™ when cleaning the unit. Special care must be taken to protect the unit’s control board and other electrical components from getting any water on them while cleaning. The use of harsh or caustic cleaning agents or materials such as bleach or coil cleaners that are not designed for PTAC products will cause damage or deterioration of the aluminum fin or coil material and is not recommended. Care must be taken not to bend the aluminum fin stock.

Routine Scheduled Maintenance

To achieve continuing top performance and high efficiency, establish a “once a year” cleaning/inspection schedule for the unit. Take the unit out of the sleeve and thoroughly clean and rinse. Be sure to include in the yearly cleaning the evaporator coils, and condenser coils, basepan, and drain passages. Scheduled maintenance can be accomplished by either qualified local maintenance staff or by an authorized servicer. They must follow the instructions described in this manual.

1. Create a water-tight seal by tightly covering the entire control panel area and fan motor with plastic. Creating this seal prevents water from entering the control area or the fan motor and damaging the unit.

2. Spray condenser coil and basepan down with water. Next spray a mild biodegradable detergent such as Simple

Green™ onto the condenser coil and basepan. Let set for five (5) minutes.

3. Rinse condenser coil and basepan with water again.

NOTE: Ensure water pressure is no higher than that of an ordinary garden hose and the water temperature no higher than 120°F.

4. Tilt the non-compressor side of the unit up no higher than

45 degrees and allow water to drain out the other side of the unit.

5. Remove excess water left in the basepan by wiping the basepan with a dry cloth.

6. Remove the water-tight seal from the motor and control panel area.

7. Reinstall unit back into wall sleeve.

8. Allow unit to dry for 24 hours before reapplying power.

When power is reapplied test unit for proper operation.

9. Place a non-acidic algaecide in the basepan to inhibit bacteria growth. Ensure the algaecide is compatible with wet coil operation and is not corrosive to the coil.

Adverse Operating Conditions Maintenance

Units operating in dusty or corrosive locations; i.e. dusty construction site or sea coast, must be cleaned more often. A minimum of four (4) times a year will maintain proper operational conditions and protect unit components.

Wall Sleeve

Clean the wall sleeve while cleaning the unit. The caulking around the sleeve should be checked to make sure that any potential air and water openings around the sleeve are properly sealed. The wall sleeve’s level should also be rechecked. Proper leveling for most installations are a ¼ bubble tilt to the outside and level from right to left. Contact your sales person for detailed maintenance or cleaning instructions.

DIAGNOSTIC MAINTENANCE

& STATUS REPORT

The Diagnostic Maintenance & Status Report provides detailed information on PTAC control operation and operational status including present modes, failures, airflow restriction warnings, operating temperatures, and past failures. The lower right hand dot on the center display flashes in this mode. In some cases the green LED located in the lower left hand corner of the touchpad below the OFF key will also be lit. This Green LED

“Status Light“ only illuminates if there is an status code that has been activated and should be reviewed. In most cases, this light indicates that the indoor room filter is dirty should be cleaned or replaced. NOTE: Dirty filters cause the unit to consume more energy than normally needed to condition a room. Once the filter has been cleaned or replaced, the LED should go out. If the LED is still illuminated after the filter has been cleaned, activate the Diagnostic and Status mode to view any active codes. The unit may need additional cleaning or maintenance of the evaporator or condenser coils. Please perform this step before calling a servicer. A servicer should be called only if cleaning the filter or coils does not clear the status code or the code indicates that servicer should be called.

DIAGNOSTIC STATUS REPORT MODE.

To enter Diagnostic Status Report mode, press and hold the up and down arrows and, while holding, quickly press the COOL key twice.

ACTIVE FAILURES.

• If there are no active failures or lockouts, the display will show a double dash, “- -”. If there is a code listed, see the unit “Diagnostic Codes” chart for a list of definitions.

OPERATING TEMPERATURES.

• If not in Diagnostic Status Report Mode, enter as instructed above and press the Fan Speed key.

• If already in Diagnostic Status Report mode, press the

Fan Speed key. The display will show the temperature of the desired set point, SP; the temperature at the wireless thermostat, rL; the indoor ambient temperature behind the filter, IA; the indoor coil temperature,

IC; the indoor discharge air temperature, Id; the outdoor coil temperature, OC; the outdoor ambient temperature,

OA; and the spare probe temperature, IH. If any of the probes are not populated the display will show the corresponding failure code.

PAST FAILURE LOG

• If not in Diagnostic Status Report Mode, enter as instructed above and press the Fan Speed key twice.

• If already in Diagnostic Status Report mode, press the

Fan Speed key. While the display is showing operating temperatures, the last 10 failure codes active or past can be requested by pressing the Fan Speed key again. The codes are displayed last entry first followed subsequently by each preceding code.

Note that modes F1 and Fd are also displayed in the normal control operation (see “Diagnostic Codes” chart).

To exit Diagnostic Status Report mode, press the OFF key.
