General Information

NOTICE:

Warnings and Cautions appear in

appropriate sections throughout this

manual. Read these carefully.

Important

WARNING

Environmental Concerns!

Hazardous Voltage with

Capacitators!

Scientific research has shown that

certain man-made chemicals can

affect the earth’s naturally occurring

stratospheric ozone layer when

released to the atmosphere.

Disconnect all electric power,

including remote disconnects before

servicing. Follow proper lockout/

tagout procedures to ensure the

power can not be inadvertently

energized. Failure to disconnect

power before servicing could result

in death or serious injury.

WARNING

Indicates a potentially hazardous

situation which, if not avoided, could

result in death or serious injury.

In particular, several of the identified

chemicals that may affect the ozone

layer are refrigerants that contain

Chlorine, Fluorine and Carbon (CFCs)

and those containing Hydrogen,

Chlorine, Fluorine and Carbon

(HCFCs).

CAUTION

Disconnect all electric power,

including remote disconnects and

discharge all motor start/run

Indicates a potentially hazardous

situation which, if not avoided, may

result in minor or moderate injury. It

may also be used to alert against

unsafe practices.

capacitors before servicing. Follow

proper lockout/tagout procedures to

ensure the power cannot be

inadvertently energized. Verify with

an appropriate voltmeter that all

capacitors have discharged. Failure

to disconnect power and discharge

capacitors before servicing could

result in death or serious injury.

Not all refrigerants containing these

compounds have the same potential

impact to the environment.

CAUTION

Indicates a situation that may result

in equipment or property-damage-

only accidents.

The manufacturer advocates the

responsible handling of all

refrigerants—including industry

replacements for CFCs such as

HCFCs and HFCs.

Responsible Refrigerant

Practices!

The manufacturer believes that

responsible refrigerant practices are

important to the environment, our

customers, and the air conditioning

industry.

Overview of Manual

CAUTION

Note: One copy of this document

ships with each unit and is

customer property. It must be

retained by the customer.

Use Copper Conductors Only!

Unit terminals are not designed to

accept other types of conductors.

Failure to use copper conductors

may result in equipment damage.

This booklet describes proper

installation, operation, and

maintenance procedures for PTACs.

By carefully reviewing the

information within this manual and

following the instructions, the risk of

improper operation and/or

component damage will be

minimized.

All technicians who handle

refrigerants must be certified. The

Federal Clean Air Act (Section 608)

sets forth the requirements for

handling, recovering, recycling and

reclaiming of certain refrigerants and

the equipment that is used in these

service procedures.

It is important that periodic

In addition, some states or

maintenance be performed to help

assure trouble free operation. A

maintenance schedule is provided at

the end of this manual. Should

equipment failure occur, contact a

service organization with qualified,

experienced HVAC technicians to

properly diagnose and repair this

equipment.

municipalities may have additional

requirements that must also be

adhered to for responsible

management of refrigerants. Know

the applicable laws and follow them.

PTAC-SVX01C-EN

General Information

Refer to proper refrigerant charge

requirements in the maintenance

section of this manual to ensure

efficient machine operation.

Refrigerant Handling

Procedures

Refrigerant Handling and

Safety

Consult the manufacturer’s material

safety data sheet (MSDS) for

information on refrigerant handling

to fully understand health, safety,

storage, handling, and disposal

requirements.

WARNING

Contains Refrigerant!

When charging is complete, purge or

drain charging lines into an approved

refrigerant container.

System contains oil and refrigerant

under high pressure. Recover

refrigerant to relieve pressure before

opening the system. See unit

nameplate for refrigerant type. Do

not use non-approved refrigerants,

refrigerant substitutes, or refrigerant

additives.

Seal all used refrigerant containers

with approved closure devices to

prevent unused refrigerant from

escaping to the atmosphere.

Use only approved containment

vessels and refer to appropriate

safety standards. Comply with all

applicable transportation standards

when shipping refrigerant

containers.

Take extra care to properly maintain

all service equipment directly

supporting refrigerant service work

such as gauges, hoses, vacuum

pumps, and recycling equipment.

Failure to follow proper procedures

or the use of non-approved

refrigerants, refrigerant substitutes,

or refrigerant additives could result

in death or serious injury or

equipment damage.

Service Equipment and

Procedures

When cleaning system components

or parts, avoid using CFC-11 (R-11) or

CFC-113 (R-113). Use only cleaning-

solvents that do not have ozone

depletion factors.

To minimize refrigerant emissions

while recovering refrigerant, use the

manufacturer’s recommended

Environmental Accountability

Policy

recycling equipment per the MSDS.

Properly dispose of used materials.

Refrigeration system cleanup

methods using filters and driers are

preferred.

Use equipment and methods which

will pull the lowest possible system

vacuum while recovering and

condensing refrigerant. Equipment

capable of pulling a vacuum of less

than 1,000 microns (1.0 mm) of

mercury is recommended.

The manufacturer urges that all

HVAC servicers make every effort to

eliminate, if possible, or vigorously

reduce the emission of CFC, HCFC,

and HFC refrigerants to the

atmosphere. Always act in a

responsible manner to conserve

refrigerants for continued usage

even when acceptable alternatives

are available.

Check for leaks when excessive

purge operation is observed.

Keep abreast of unit enhancements,

conversion refrigerants, compatible

parts, and manufacturer’s

recommendations that will reduce

refrigerant emissions and increase

equipment operating efficiencies.

Do not open the unit to the

atmosphere for service work until

refrigerant is fully removed/

recovered.

Recover and Recycle

Refrigerants

When leak-testing with trace

refrigerant and nitrogen, use HCFC-

22 (R-22) rather than CFC-12 (R-12) or

any other fully-halogenated

refrigerant.

Never release refrigerant to the

atmosphere!

Always recover and/or recycle

refrigerant for reuse, reprocessing

(reclaimed), or properly dispose if

removing from equipment.

Be aware of any new leak test

methods which may eliminate

refrigerants as a trace gas.

Perform evacuation prior to charging

with a vacuum pump capable of

pulling a vacuum of 1,000 microns

(1.0 mm) of mercury or less. Let the

unit stand for 12 hours and with the

vacuum not rising above 2,500

microns (2.6 mm) of mercury.

Always determine the recycle or

reclaim requirements of the

refrigerant before beginning the

recovery procedure.

Obtain a chemical analysis of the

refrigerant if necessary.

Questions about recovered

refrigerant and acceptable refrigerant

quality standards are addressed in

ARI Standard 700.

A rise above 2,500 microns (2.5 mm)

of mercury indicates a leak test is

required to locate and repair any

leaks. A leak test is required on any

repaired area.

Charge refrigerant into the

equipment only after equipment

does not leak or contain moisture.

cool the occupant wants the room.

Fan

Mode

The setpoint is set by pressinging the

up/down buttons on the interface

module. These buttons do not scroll

(i.e. holding the button will not

continue to adjust the setpoint value)

because each adjustment of the

setpoint value requires its own

unique button press.

1. Ventilation Door Function

6. Indoor temperature calibration

The power door works based upon

control logic functions. When the unit

is on, the vent door will open to allow

fresh air to be conditioned before

entering the room. When the unit is

off, the door closes to prevent

unconditioned air from entering the

room.

The indoor temperature can be

calibrated to match an independent

reading. The adjustment range is +/-

10.0°F (6°C) with a resolution of 1°F

The range of temperature control

setpoints can be limited using this

configuration parameter. After the

controller has determined the

desired user setpoint from the

display, the resulting value is

validated against the setpoint limits.

There are four valid combinations of

heating and cooling setpoint limits:

The controller saves the last inputs

that the user has chosen 5 seconds

after the user has ceased changing

them. These settings will be used

after the next power cycle or

controller reset.

Operation without configuration

The controller tests the configuration

for validity. If the data is corrupted

the controller will revert to default

values for every parameter. A

diagnostic code will be displayed

when using the default values.

These set point limits apply to both

the occupied and unoccupied

standby, heating and cooling

setpoints. This setting is adjustable

“on-the-fly” and will not force the

Occupied Standby state

Energy Management

System

When the controller is in occupied

standby state, the unit runs space

comfort control using the occupied

standby setpoints. All heating/

cooling/ventilation features are

enabled. Because the occupied

standby setpoints cover a wider

range than the occupied setpoints

the demand for heating and cooling

the space is reduced.

Occupancy States

The controller is designed to handle

two possible occupancy states:

•

occupied

occupied standby

When the Energy Management

System input is present, it is possible

for the controller to switch between

the two occupancy states.

If the EMS input is not connected, the

controller will always assume the

occupied state.

Operation

Remote Thermostat Control

Sequence of Operation

Each unit can be operated from any

standard 4 or 5-wire, remote-

mounted thermostat. Also, the unit

has a built-in low voltage power

source that can accommodate either

a manual, auto changeover, or

programmable thermostat.

Automatic 3-minute

Compressor Lockout

After the compressor cycles off, it

will not restart for three minutes.

This feature prevents the

compressor from short cycling and

extends the overall life.

Fan

Mode

Setpoint Limiting

The setpoint limiting feature reduces

energy costs by controlling the

maximum setpoint in heating and

the minimum setpoint in cooling.

Automatic 2nd Stage Electric

Heat (PTHE only)

Figure 17.

Digital display module

If the room temperature falls to 2.5°F

below the setpoint temperature or

the unit compressor fails, the reverse

cycle heat is shut off and the electric

heat is turned on.

Fan Operation

The fan speed may be user selected

as either high or low. Fan cycling

versus continuous is operation

configurable. See section on

configuration for details.

Active Defrost (PTHEs only)

PTACs have an active defrost system

that removes ice build-up on the

outdoor coil, which may occur

during the heat pump cycle.

Indoor Room Freeze

Protection

Front Desk Control (FD1, FD2

Inputs)

When the unit senses room

temperatures of 40°F or below, the

unit activates the indoor fan motor

and either the electric resistance

heater or the hydronic heater to help

prevent pipes or fixtures from

freezing.

Remote Thermostat

Operation

The energy management input is

used to move the setpoint up in the

case of cooling and down in the case

of heating. This conserves energy

by reducing the demand in the

space.

The GL, GH, O, W, Y, R, and C

terminals provide control inputs for a

remote wall-mounted thermostat.

The terminals listed control the

operation of the unit when no

display module is used. A display

module will take precedence over

any of these inputs.

This also overrides the Energy

Management System input for unit

mounted or wall mounted display

modules

The energy management input is a

dry contact closure; typically this is

driven from either a occupancy

sensor or a front desk control

system.

Mode Button Operation

Random Restart Function

OFF - cooling and heating functions

stop.

This function allows random restart

of the PTAC units in the event of a

power outage. The restart delay

reduces the initial inrush current

from the building to help prevent a

second power outage caused by too

much current draw.

HEAT - room temperature is

maintained by cycling in heat pump

mode or electric heat. The model

PTHE switches from heat pump

mode to electric heat when the

outdoor air temperature is below

20°F (approximately), or when the

heat pump cannot keep up with the

heating load when using a two-stage

thermostat.

The random restart function will

occur after every power up cycle by

delaying the operation of the unit for

0 to 90 seconds. Compressor

minimum off time is enforced after

the random restart function has

completed.

COOL - room temperature is

maintained by cycling the air

conditioner.

Door Switch Occupancy

Sensor

FAN - the fan runs at the user

selected speed or runs as otherwise

configured.

front. Reinstall the cabinet front

on the unit.

Remote Fan Operation

PTACs can operate a remote fan to

provide conditioned air to additional

rooms or areas that are not well

ventilated. The remote fan operates

any time the PTAC indoor fan is

operating.

Screws

The remote fan requires a 24 VAC, 3

VA maximum relay that connects to

the control board RF and C terminal

user inputs. The relay and remote fan

are field supplied. Refer to the wiring

diagrams section for wiring details.

Vent Control

Figure 18. Discharge air grille

Vent control draws fresh air into the

conditioned area to provide

ventilation when the indoor fan is

operating. However, this may

increase heating cooling loads and

operating costs.

To obtain access to the vent control,

remove the cabinet front and locate

the vent control lever on the left side

of the chassis. Push the vent control

lever up to open the vent or down to

close.

The unit ships with the vent door

closed and secured by a screw.

Maintenance

Wall Sleeve

Intake Air Filter

Maintenance Procedures

Clean the wall sleeve every four

months or more often as the

atmospheric conditions require.

The intake air filter and vent door

filter are both constructed of durable

polypropylene. Clean filters monthly

to ensure proper unit operation.

Perform the following maintenance

procedures to ensure proper unit

operation.

Remove any debris from the bottom

of the panel, and from around any

internal or external drain kit

accessory item prior to using water

or detergent. This will ensure that no

debris clogs up the drain holes.

The fan must be off before the filters

are cleaned.

WARNING

Live Electrical Components!

To remove the air filters, grasp the

top of the filter and lift out of the

front cabinet (Figure 19.) Reverse the

procedure to reinstall the filters.

During installation, testing, servicing

and troubleshooting of this product,

it may be necessary to work with

live electrical components. Have a

qualified licensed electrician or other

individual who has been properly

trained in handling live electrical

components perform these tasks.

Failure to follow all electrical safety

precautions when exposed to live

electrical components could result in

death or serious injury.

The use of harsh cleaning materials

may cause a deterioration of the

bottom panel over time. Do not use

a high pressure cleaner because it

could spray the side or top panel

insulation material and cause future

air quality problems like mold and

mildew.

Clean side and top panel insulation

material with a lint brush or piece of

tape. Press tape against insulation

lightly and slowly peel away to

remove dirt and debris.

WARNING

Hazardous Voltage!

Figure 19. Intake air filter removal

is through top of unit. Inspect and

clean filters monthly for proper unit

operation.

Compressor/Fan Motor

Disconnect all electric power,

including remote disconnects before

servicing. Follow proper lockout/

wiring. However, based on the current step in the test sequence, the auxiliary heat may not be on. Refer to the

Manual Output Test section.

Unit wiring

The wiring between the controller output and the auxiliary heat must be present and correct for normal operation.

Indoor Coil Freeze

protection

The compressor has been turned off because the indoor coil temperature has fallen below 35°F and has not risen

above 50°F.

Normal operation

Defrost Cycle

Auxiliary heat may not be needed to meet the load conditions see the section dealing with Auxiliary Heat Control.

During the active defrost cycle the auxiliary heat is controlled off. See the section on defrost control. Reversing

Valve output does not energize.

Table 36. Ventilation output does not energize

Probable cause

Explanation

Random restart timer

Selected mode OFF

Diagnostic present

No power to controller

All controller outputs remain off until the timer expires.

When off is selected at the display to the controller, the unit controls all outputs off.

A specific list of diagnostics affects unit operation. For more information, see the Diagnostics section in the manual.

If the controller does not have power, the compressor does not operate. For the controller to operate normally, it

must have an input voltage of 115 or 230/208, 265 VAC.

Manual output test

The controller includes a manual output test sequence you can use to verify output operation and associated output

wiring. However, based on the current step in the test sequence, the ventilation output may not be on. Refer to the

Manual Output Test section.

Unit wiring

The wiring between the controller output and the ventilation must be present and correct for normal operation.

See the section on Ventilation operation.

Normal operation

Defrost Cycle

During the active defrost cycle the outdoor fan is controlled off. See the section on defrost control.

Troubleshooting

Table 37. Condensate pump does not energize

Probable cause

Explanation

Random restart timer

Selected mode OFF

All controller outputs remain off until the timer expires.

When off is selected at the display to the controller, the unit controls all outputs off.

No power to controller If the controller does not have power, the compressor does not operate. For the controller to operate normally, it

must have an input voltage of 115 or 230/208, 265 VAC.

Manual output test

The controller includes a manual output test sequence you can use to verify output operation and associated output

wiring. However, based on the current step in the test sequence, the condensate Pump may not be enabled. Refer to

the Manual Output Test section.

Unit wiring

The wiring between the controller output and the Condensate Pump must be present and correct for normal

operation.

Normal operation

Unit wiring

Condensate Pump is available only with Heat Pumps. Unit is in active defrost, or outdoor temperature is below enable

point.

The wiring between the controller outputs and the fan relays and contacts must be present and correct for normal

condensate pump operation.

Defrost Cycle

During the active defrost cycle the condensate pump power is removed. See the section on defrost control.

Table 38. Output on when the mode is off

Probable cause

Fan Configuration

Freeze Protection

Explanation

Fan is configured to run on high in off mode (see configuration section).

While in off mode, freeze protection may be active. This will cause the indoor fan to run at high speed, and the

remote fan and auxiliary heat will be on.

Fan Delay Off

The indoor fan continues to run after the compressor or auxiliary heat will be on.
