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

property handle the unit.

• Automatic 3-minute compressor lockout - After

the compressor cycles off, it will not restart for three

minutes.

• 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.

• Indication LEDs - The control panel has LEDs that

correspond to fan operation and to Indicate unit

status. The LEDs next to the selections ON/OFF,

FAN, COOL, and HEAT indicate which operational

mode Is active.

• High Pressure Protection - The unit will shut off

automatically when the pressure in the system

is over 638 psi and within 10 minutes, after the

compressor turns off, the unit will restart when the

pressure turns back below 551 psi. This protection

can effectively avoid the burst and leakage of

pipes, lessen the system failures and prolong the

service life.

• Failure Tolerance - If the unit is in protection mode

less than 4 times in one hour, the accumulation

times will reset to avoid system failure. Only when

the unit enters protection mode more than 4 times in

one hour will the system fail to restart automatically

and need manual restart.

• Standard Physical Dimensions - The series PTAC

uses standard same dimensions, 42” wide x 16”

high x 13-3/4” deep.

Replacement of older units is made easy.

• Weather - Protected Electrical Components

-Vital electrical components are protected from the

weather by locating them on the indoor side of the

weather barrier.

• Highly Featured Microprocessor Controls

- Microprocessor controls are programmed to

interface with the temperature sensors to maximize

comfort conditions for the room occupant.

Thermistors are used to sense small changes in

temperature to give excellent room control and

allow the microprocessor to monitor and react to

changing conditions.

• Automatic Emergency Heat on Heat Pump

Units-Automatically uses electric resistance heat if

the heat pump falls.

• High-Temperature Heat Pump Operation

Protection

-Automatically protects the compressor if heat pump

is operated with high indoor coil temperatures.

Power to the outdoor fan and the compressor

are turned off if the indoor coil gets too hot during

heat pump operation to prevent damage to the

compressor.

PACKAGED TERMINAL A/C OWNER’S MANUAL Heat Controller

• Fan Motors Permanently Lubricated - All units

have two fan motors for quiet operation and

maximum operating efciency.

Motors are permanently lubricated to reduce

maintenance and totally enclosed to keep dirt and

water out of the motor windings.

• Indoor Fan Speed Selections LOW /HIGH/AUTO

- Unit may be operated in low, high or auto fan

speeds. Some speeds may not be present based

on unit capacities.

• Rotary Compressor - smoother operation for quiet,

dependable service and high efciency.

• Indoor Coil Frost Control - prevents indoor coil

from freezing. Frost can form on the Indoor coil

when the unit is operated in cooling when the

outdoor temperature is low. The unit automatically

shuts the compressor off until the indoor coil

temperature warms to the point where frosting will

no longer occur, then restarts the compressor.

• LS Control (front-desk control) - The unit can

be turned ON/OFF by a front desk control switch.

The control wire, colored purple, locates in the wall

mounted thermostat interface (refer to Fig. 7 on

page 8).

The control logic as belows:

1. Turn ON unit: short circuit R and LS then release

one time within 5 seconds.

2. Turn OFF unit: short circuit R and LS then release

for twice within 5 seconds.

3. Force unit shut down for one time: connect LS to R

for over 5 seconds and then release.

NOTE: After force shut down, you can turn the unit

ON again by hand-held remote controller or the

control panel.

• Special control functions for DIP switches - The

DIP switches are on main board. No. 5 auto

heating (for units with heat). When unit is connected

to the power supply, and room temperature Is

lower than 10°C/50°F for 3 minutes, unit will start

heating automatically no matter what the setting

mode is. Only when room temperature reaches

13°C/55°F will heating stop.

ON position enables this function.

No. 6 -Electric Power-off Memory. After power on,

the unit will run the same settings as last time.

ON position enables this function.

No. 7-Fan CON/CYC for heating.

ON position enables continuous fan for heating. The

default setting Is fan cycled for heating.

No. 8 -Fan CYC/CON for cooling ON position

enables fan cycle for cooling. The default setting is

fan continuous for cooling.

WARNING: Before service, you must disconnect

the power cord to avoid electric shock! Do not

reprogram DIP switches No. 1 to No. 4, when

powered this could cause damage or re. Power the

unit on again, the new function will be activated.
