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.

THE INSTALLATION AND SERVICING OF THIS EQUIPMENT
MUST BE PERFORMED BY QUALIFIED, EXPERIENCED TECH­NICIANS ONLY.

Due to policy of continual product improvement, the
right is reserved to change specifications and design
without notice.

• 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.

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.

REMOTE CONTROL INPUTS

g

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.

THERMOSTAT LOCATION

This unit is designed to be operated with remote wall mounted
thermostats. For further information on thermostats approved
for use with this unit, contact your sales representative.

For best performance results, the thermostat should be located
approximately five feet above the floor on a vibration free,
inside wall in an area with good air circulation.

10

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.

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.

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.

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.

Basepan and Condenser Coil

CAUTION

O NOT USE COMMERCIAL GRADE COIL CLEANERS. SOME OF THESE

CLEANERS MAY CONTAIN
WHICH CAN SHORTEN THE LIFE OF THE CONDENSER COIL.

Before cleaning the basepan and condenser coil, turn OFF unit
mode switch and disconnect power to the unit. To disconnect
power, either unplug the power cord at the wall outlet or
subbase, or disconnect power at the fuse box or circuit breaker.

COMPONENTS.

Clearance Check

Clearances around the unit should also be checked to make sure
that the intake air and discharge air paths have not become
blocked or restricted. A minimum of eight inches clearance is
needed from unit to furniture , beds, or other objects for proper
operation. Restricted discharge or intake air will reduce the
unit’s operational performance. In severe airflow restrictions
damage can occur to unit components such as the compressor,
electric heater or fan motor.

OBTAINING SERVICE

CONFIGURATION SETTINGS

In the event this unit requires repair or servicing beyond what is
covered in this manual, contact an authorized service organiza­tion.

To obtain an authorized servicer, contact your sales representa­tive or agency.

NORMAL OPERATING
SOUNDS AND CONDITIONS

Water trickling sounds

Water is picked up and distributed over the coil. This
improves the efficiency and helps with water removal.

Water dripping

Water will collect in the base pan during high humidity days.
This can cause overflow and drip from the outside of the unit.

Air sounds

The fan cycle switch sets the operational mode of the fan in
the ON position. The fan will run continuously whenever
power is applied in this mode. In the AUTO position, the fan
will cycle on and off with the compressor or electric heater.

Starting delay

You may notice a few minutes delay in the starting if you
try to restart the unit too soon after turning it off or if you
adjust the thermostat right after the compressor has shut
off. This is due to a built in delay to protect the compres­sor.

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.
