PACKAGED TERMINAL A/C SERVICE MANUAL Heat Controller

Controller Functions and Operating Methods

The relationship between Centigrade and Fahrenheit is: Tcentigrade=Tfahrenheit*1.8+3.2

A. Temperature Parameter

n Indoor setting temperature (Tpeset)
n Indoor ambient temperature (Tamb)

B. System Basic Function

The compressor has a 3 minute time delay before it will start as a protective feature. Once the compressor begins to run, the
compressor cannot be stopped by changing the set temperature. However, it can be stopped by changing the mode the unit is
operating in or by turning the unit off. Once the unit is restarted, the compressor will not restart until the 3 minute time delay
has surpassed. (The compressor can be stopped immediately at the time of mode switchover, turning off the unit, adjusting set­ting temperature and when in protective modes.)

1. Cooling Mode

When Tamb ≥Tpreset+2°F (1°C), the unit runs in cooling mode. Meanwhile, the compressor runs and the fan runs at the preset

fan speed.

When Tamb≤Tpreset-2°F (1°), the unit will turn OFF, the compressor will stop, however the fan will continue to run at the preset

fan speed;

When Tpreset-2°F (1°C)<Tamb<Tpreset+2°F (1°C), the unit keeps running with the previous settings.
n In this mode, the unit’s display will read the set temperature and the cooling LED is illuminated.

2. Fan Mode

In this mode, only the fan runs. The compressor won’t run and the temperature can’t be adjusted. The fan speed can be
changed. The display will read ambient temperature (32~99°F, when ambient temperature is higher than 99°F, it will display
H1; when ambient temperature is lower than 32°F, it will display L0), and the fan LED is illuminated.

3. Energy Saving Mode

When Tamb≥Tpreset+2°F (1°C), the unit runs in cooling mode. Meanwhile, the compressor runs and the fan runs at the preset

fan speed.

When Tamb≤Tpreset-2°F (1°C), the compressor will turn off while the fan will continue to run for 3 minutes; If Tamb≤Tpreset­2°F (1°C), the fan will stop for 10 mins, and then turn on for 2 minutes at the preset speed. It will continue to cycle the fan on
and off in this sequence until Tamb≥Tpreset+2°F (1°C), then the fan and the compressor will start up (the start-up of compres­sor will be delayed for 3 minutes; the fan start up will occur 30 seconds prior to the compressor).

4. Heating Mode

When Tamb≤Tpresent-2°F (1°C), the unit is runs in heating mode. Meanwhile, the electric heater will start after the fan
runs for 3 seconds. When Tamb≥Tpresent+2°F (1°C), the electric heater will turn off and the fan will continue to run til Tair
exhaust≤90°F and the unit stops (the fan will run 15 seconds after the unit stops); Then the fan will stop for 10 minutes and
run for 1 minute at low fan speed. It will continue to cycle the fan on and off in this sequence until Tamb≤Tpreset-2°F (1°C).

5. OFF mode

If the OFF mode is selected the power button is active on the control panel. The freeze protection feature remains enabled, even
when the unit is OFF.
If the UP or DOWN buttons are pressed the display will turn off, after the ambient temperature is displayed for 15 seconds. The

indoor light will also turn off after 15 seconds.

6. Freeze Protection

This feature works in OFF, cooling and fan modes.
If the indoor ambient temperature is lower than 40°F (5°C) for 5 seconds, the electric heat mode and the freeze protection

mode will start up.

When the indoor ambient temperature is more than 50°F (10°C), the freeze protection mode will turn off.
After entering into the freeze protection mode, it can’t be stopped by pressing any buttons. During freeze protection mode, the
display reads “FP” and the green running LED is illuminated. During the freeze protection mode, the unit can’t be controlled by

the wall thermostat.

Controller Function and Operating Method continued

7. Open circuit and short circuit of temperature sensor

If the temperature sensor has an open circuit, it will send an error signal. The error signal is displayed (see table below). If
malfunction of temperature sensor is detected, all the loads except the indoor fan will be turned off in cooling and fan mode;
However, in heating mode, all the loads will stop immediately and the indoor fan will blow off any residual heat for 6 seconds.
When the temperature sensor has malfunctioned and the fan has stopped, the fan can’t be restarted. In cooling and fan mode,
the fan will run normally. If the malfunction of the temperature senor occurs during the time of blowing residual heat, the fan will

stop after 1 minute.

C. Button and Displays

1. Buttons

Ther are ve buttons in all, ON/STOP, UP, DOWN, MODE and FAN SPEED.

1. In the OFF mode, press the ON/STOP button to turn on the unit: In OFF mode, if the UP or DOWN button is pressed, the dis­play will turn off after displaying in the indoor temperature for 15 seconds; If the MODE button is pressed in the OFF mode,
the controller will resume to the running status before the unit was turned off. The green running LED is illuminated.

2. In ON mode

 ON/STOP: After pressing the ON/STOP button, the unit can be switched between ON and OFF mode
 MODE: In ON mode, after pressing the MODE button, the unit be switched between cooling, fan and heating modes; In

the OFF mode, after pressing the MODE button, the controller will run at the running status before turning off the unit.

 FAN SPEED: In ON mode, after pressing the FAN SPEED button, you can select the high, medium and low fan speed.
 UP, DOWN: Adjust the set temperature 61-86°F (16~30°C) by pressing the UP and DOWN buttons. Set temperature

ranges can be specied through conguration of the dip switches.

2. Display and LED Display

1. Mode LED display: when the A/C is runing, the corresponding LED is illuminated.

2. Running/power LED: In ON mode, the LED is green in color; In STOP status, the controller is red in color.

3. Fan speed display: When the A/C is running on high, medium and low fan speed, the corresponding LED is illuminated.

4. Display: In cooling and heating modes, the display shows the set temperature (in fan mode it displays the indoor ambi-

ent temperature).

5. Malfunction Display: After energization, when there’s malfunction or protective feature operating the STATUS LED will
blink to display an error code continuously. The error codes are shown below: Priority is decreasing from 1 to 8. In OFF
mode, the display will not show the error code (except for freeze protection). When multiple errors occur, the unit dis-

plays only the protection with the highest priority.

E. Unit controls

The PTAC can be congured by the display and a set of dip switches.

1. TEMP CONTROL

Temp Control is used to maintain room temperature. Compressor will cycle on and off to keep room at the

requested level of comfort.

COOLER—Lowers temperature. (Minimum temperature setting is 61°F/16°C)
WARMER—Raises temperature. (Maximum temperature setting is 86°F/30°C)

2. FAN SPEED, MODE & ON/OFF
FAN SPEED—Set fan operation for HI, MED, or LO speed.
MODE-COOL—For cooling
MODE-HEAT—For heating

NOTE: If unit is a heat pump, raising the heat setting by 5°F will cause unit to use its electric heating elements for one

cycle in order to reach the new requested temperature quickly.

MODE-FAN—For fan--only operation
ON/OFF—Turns the unit on or off.

NOTE: The LED above the ON/OFF button will be green when unit is ON and red when the unit is OFF. All other

LEDs will be off when unit is set to OFF mode.
NOTE: Power remains connected to unit even when the unit is in the OFF mode.

KEYPAD CONFIGURATION

Allows further conguration of system to desired application such as whether th unit displays in °F or °C, whether the display
shows the set point or room air temperature, and to set controls for sensor biasing. Changes do not take affect until power is

cycled on the unit.

To enter Keypad conguration

Cycle power to unit. Press and hold the Fan Speed Button and the COOLER button for 5 continuous seconds, within 30
seconds of the unit being powered up. If the unit has had power for more than 30 continuous seconds, keypad conguration
cannot be entered. When keypad conguration mode is rst entered, it will default to Fahrenheit/ Celsius Display Mode.

To scroll through the Keypad Conguration Options

Press and release the Fan Speed button. The stored value will be displayed.

To modify conguration settings

Press and release the Setpoint Up or Setpoint Down buttons.

To exit Keypad Conguration

Keypad Conguration will end on its own 30 seconds after the last button is pressed or when the MODE button on the Key­pad is pressed.

In the conguration mode, four different options can be selected by using the fan speed button. The options are described below:

Fahrenheit/ Celsius Display Switch:

Changes between degrees Fahrenheit and Celsius on the display. An “F” indicates Fahrenheit and ‘C’ indicates Celsius. De­fault is degrees “F”.

Indoor Air Temperature Sensor Biasing for Cooling mode:

Sometimes known as an anticipator, the air temperature sensor bias is used to adjust the room air temperature reading in

cooling mode. (Not normally required.)

Indoor Air Temperature Sensor Biasing for Heating mode:

Sometimes known as an anticipator, the air temperature sensor bias is used to adjust the room air

temperature reading in heating mode. (Not normally required.)

Indoor Temperature Display:

Change between showing setpoint only on the display during heating and cooling modes “SP” or displaying

room temperature during heating and cooling modes “AA”. (“SP” mode is the default mode.)

If “SP” is selected, only the setpoint will be displayed during heating and cooling modes, regardless of what the real

temperature is in the room.

If “AA” mode is selected, the room temperature will be displayed during heating, cooling and fan only modes.

— If the mode button has been changed to either heating or cooling modes, setpoint will be displayed for 10 sec-

onds. After the 10 seconds, the room temperature will again be displayed.

— If the on/off button is pressed (when the unit is off) and the last mode was either cooling or heating, the setpoint

will be displayed for 10 seconds before displaying room temperature.

— During heating and cooling modes, if either the up or down setpoint key is pressed, the display will show the

setpoint until 10 seconds after the last up or down key is pressed. Then the room temperature will be displayed

again.

To restore factory setting

During standby of OFF mode, press fan speed and UP buttons simutaniously for 3 seconds. The display will show “00” for 3

seconds.

Electric Heating Only / Emergency Heat (For Heat Pump Units Only)

This setting is typically used for EmergencyHeating.

Wall Thermostat Enable

A wired wall thermostat can be connected to the unit. If it is, this dipswitch must be moved to the Wall Thermostat Enable Posi­tion, before the wall thermostat will begin control.

Heat and Cool Fan CON/CYC Dip--switches

Allows the fan to operate in continuous or cycle modes while the unit is in heating or cooling mode (continuous or cycle):

CON (Continuous)

Allows fan to run continuously, circulating air even when the temperature setting has been satised. This switch helps to

maintain the room temperature closer to the thermostat setting.

CYC (Cycle)

This setting allows the fan to cycle on and off with the compressor or electric heater. The fan stops a short time after the

temperature setting is satised.

Setpoint Temperature Limits

Provides a restricted range of temperature control.

Room Freeze Protection

If unit senses a room temperature below 40°F, the fan motor and electric strip heat will turn on and warm the room to 50°F. The
fan stops a short time after the temperature is satised.

F. Protective Features

1. Frost Protection Mode (heat pump):

When the compressor is running under wired controller’s heating signal. If T outer tube ≤ 28°F (-2°C) is detected for 1 min­ute successively, the compressor and outdoor fan will stop running. Then indoor fan will run normally according to the wired
controller’s signal. If the heating is required then the heat pump operation will stop the compressor and run the electric
heater solely. However, if T outer tube ≥ 40°F (5°C) is detected for 10 minutes, it will stop the frost protection mode.

2. High temperature protection for evaporator:

When the compressor is running under wired controller’s heating signal, if T inner tube ≤ 136°F (58°C) is detected for 1
minute successively, the compressor and outdoor fan will stop running and the indoor fan will run normally according to the
wired controller’s signal. If heating is required the heat pump operation will stop the compressor and run the electric heater

solely after 15 seconds.

3. Antifreezing protection for evaporator:

Whe the compressor is running under wired controller’s heating signal, if T inner tube ≤ 28°F (-2°C) is detected for 1 minute
successively, the compressor and outdoor fan will stop running and the indoor fan will run normally according to the wired
controller’s signal. (Before the protection, if there isn’t a signal for indoor fan, it will run at medium fan speed. After entering
the protection mode, it will run at the preset fan speed before protection) until T inner tube ≤ 40°F (5°C) is detected for 2
minutes, the the system will quit the antifreezing protection mode.

4. Higher temperature protection for outdoor condenser:

Under the wired controller’s signal, the compressor is running. If T outer tube ≤ 149°F (65°C) is detected for 1 minute suc­cessively, the high temperature resistant protection mode will be enabled. The compressor will stop running, the indoor fan
will run normally according to the signal of wired controller and the outdoor fan will run constantly until T outer tube ≤131°F
(55°C) is detected for 2 minutes successively then the protection mode will stop.

POWER CONNECTION OPTIONS

Appropriate power cord accessory kit is determined by the voltage, and amperage of the branch circuit. The unit does not come
with a power cord (or hard wire kit). An accessory power cord kit must be ordered to connect the unit to the outlet. If the unit is

to be hard wired, an accessory hard wire kit must be ordered.

IMPORTANT: For 265V units, if a power cord is selected, it must plug into the 265V subbase accessory.

Cord-connected Units

The 250V eld supplied outlet must match the plug for the standard 208/230V units and be within reach of the service cord.
The standard cord-connected 265V units require an accessory electrical subbase for operation. Refer to Table for proper recep-

tacle and fuse type.

Power Cord Protection

The power cord for 230/208v units provide power cord re protection.Unit power automatically disconnects when unsafe conditions
are detected. Power to the unit can be restored by pressing the reset button on plug head. Upon completion of unit installation for
230/208V models, an operational check should be performed using the TEST/RESET buttons on the plug head.

NOTE: The 265V models do not incorporate this feature as they require use of the electrical subbase accessory.
