FEATURES

Indoor Coil Freeze Protection (Standard)

Prevents indoor coil from freeze up in cooling mode.

• Indoor coil freeze up can occur due to a dirty air lter,

restricted or poor air ow, low refrigerant charge or low

room or outdoor temperatures.

• This can cause compressor damage.

• Should freeze condition be detected, compressor and outdoor fan switch off for minimum of three minutes

until freeze condition is satised.

• During this time the indoor fan continues to run to aid in defrost process.

Condensate Removal (Standard)

RetroAire replacement unit, cooling operation, is designed to eliminate condensate by slinging it onto outdoor coil.

• Condensate drains through the bulkhead to the area near the outdoor fan.

• Unit as part of normal operation produces condensate and collects it in the unit's base pan. It is picked up there by the outdoor fan slinger ring and deposited onto

the condenser coil. This improves the unit’s efciency

by maintaining reduced refrigeration system pressures.

• Base pan has overow notches. If too much condensate

is produced notches allow condensate to ow out of the

base pan and into the wall sleeve out of the building.

Anti-Short Cycle Timer (Standard)

Microprocessor control uses this timing to prevent compressor short-cycling.

• When the compressor cycles off on heating or cooling call, controller starts a 180-second timer.

• Compressor is not allowed to start until this time has elapsed.

• On initial power-up or after a power failure, this timing occurs after the random start timing.

Power Cord With Integral Safety Protection (Standard)

All PTAC/PTHP units rated 250V or less are equipped with power cord with integral safety protection as standard.

• Providing personal shock protection as well as arcing

and re prevention. Device is designed to sense any damage in line cord and disconnect power before a re

can occur.

• Tested in accordance with Underwriters Laboratories, cord set offers a unique “passive” operation, meaning unit does not require resetting if main power is interrupted.

Thermostatic Drain Pan Valve

(Standard On

Heat Pump Units)

Heat pump models (PTHP), condensate can accumulate in the outdoor drain pan during heat pump cycle.

• PTHP units include a thermostatic drain valve that opens when outdoor temperatures fall below 60°F (15°C).

• When drain valve opens, condensate ows from the drain pan onto the bottom of the wall sleeve, and drains to the outside.

• Keeping the base pan free of condensate water, which could freeze during colder outdoor temperatures.

Random Start Feature (Standard)

Random start feature is initiated on initial power-up or after a power interruption.

• Controller adds a random time delay (from 5–120 seconds) on start-up, preventing compressor from starting.

• This staggers the start of multiple units in a single facility, preventing a large surge if all units started at the same time.

Heat Pump

• Heat pump units are “Limited Range” and should be equipped with back-up electric resistance or hydronic heat.

• Limited Range heat pumps are designed to operate when outdoor temperatures are between 70°F(21°C) and 40°F(4.4°C) and with maximum indoor temperature of 80°F(26.6°C).

• Unit is equipped with a reversing valve energized for cooling and de-energized in heating mode.

• Electric heating or hydronic heat will operate using onboard control logic below operating conditions of the heat pump.

Hydronic heat package may be selected in lieu of electric heat. Heating operation is same as that of units with electric heat.

Aquastat Connection (Optional)

All replacement PTAC/PTHP's with hydronic heat are supplied with standard line volt Aquastat connection. Field installed Aquastat delays fan operation until hydronic coil reaches temperature of 100°F (38°C).

Motorized Fresh Air Damper (Optional)

Motorized fresh air damper allows fresh air into the space to be conditioned. When the Fresh Air switch is in "YES" position, damper door is open and allows fresh air into the space. This is only available when the indoor fan is on. When damper door switch is in the "NO" position, the damper door is closed and does not allow air in the space.

Optional Wall-Mounted Thermostats

PTAC/PTHP compatible thermostats.

• Manufacture offers single stage, cool/heat, thermostat that can be used in all RetroAire cooling, heating or heat pump applications.

• Thermostat has adjustable setpoint range of between 45°F(7°C) and 90°F(32°C).

• For heat pumps manufacture offers a 2 stage heat/cool thermostat which allows for emergency heat.

Selecting A Thermostat

When selecting a thermostat for the PTAC/PTHP choose a single stage heat/cool, 24V thermostat.

Straight cooling with electric heat or hydronic heat (R10C — PTAC's) select a thermostat compatible with a cooling/ electric heat system. Thermostat should have “R”, “Y”, “W”, "C" and “G” terminals.

Heat Pump With Electric Heat (R__H - PTHPS)

Select a thermostat compatible with cooling/single-stage heat/heat pump system.

INSTALLATION - R50C

Installation

Verify existing wall thickness. Distance from condenser coil to outdoor louver varies with wall sleeve

depth. Two sets of air bafes are included with each

unit to accommodate most installation requirements.

Manufacturer offers alternate air bafe kits for unique

applications. Wall sleeve depth is required when

ordering to ensure proper bafe size.

Verify Weather Angle -

A. Slide the unit into the wall sleeve.

B. If supply duct on cooling chassis does not line up

with supply vent on room cabinet, it is possible factory installed weather angles on top and sides will have to be reversed. This will allow approximately 1” of adjustment for alignment with supply vent when mounting unit to the wall sleeve.

See gures 14 and 15.

C. Slide unit back in the wall sleeve. Verify proper t.

Install Bafes - Slide unit out of wall sleeve.

Remove both sets of bafes from the kit bag supplied

with unit.

FINAL INSPECTION & START-UP

Before Operating The Unit

Install unit per the instructions outlined in this manual and all applicable local and national codes.

Verify electrical supply matches electrical requirements of the unit, and unit is properly grounded.

Examine control box. Verify all wire connections are secure, and control board jumpers are in proper positions.

Verify chassis is properly tted to wall sleeve and

securely mounted to surrounding framing.

Verify chassis is level: Pour water into drain pan.

Verify it ows through the drain hoses to condenser

side of unit.

Verify indoor blower wheels and outdoor fan blades are secured to their motor shafts, and rotate freely.

Verify all sheet metal panels are in place and secure.

Attach front panel to the existing cabinet enclosure.

Verify nothing interferes with room discharge air or return air of units.

Examples:

Check for curtains or drapes that obstruct air ow. See gure 27 and gure 28.

Check for plush carpeting that can obstruct return air.

These types of obstructions can cause serious damage to the chassis.

Figure 27 - Proper Air Flow Diagram

Figure 28 - Restricted Air Flow Diagram

Any obstruction of supply air, including use of deector bafes, may cause condensate to form on louver or cabinet. See gure 28.

For optimum performance of your PTAC/PTHP, avoid

restricting the air ow. Position of curtains or drapes

over supply air grille may cause air to recirculate without cooling the room. Unit will short cycle and may cause

premature compressor failure. See gure 28.

Important Information

• Room temperature must be above 65°F (18°C) for compressor to operate in cooling mode on PTAC's with unit-mounted controllers.

• Room temperature must be below 85°F (29.4°C) to energize the heater on PTAC's with unit-mounted controllers.

• Room temperature must be below 85°F (29°C) for hydronic heater to operate on PTAC's with unitmounted controllers. Hydronic valve is 24 Vac normally open valve. Should power be interrupted, valve will default to open position.

• When unit is rst powered up, high humidity conditions may cause condensation to form on discharge grill. Keep doors and windows closed to reduce humidity allowing condensation to evaporate.

Cooling Cycle

Place thermostat or system switch in COOL position.

Adjust thermostat to cooler temperature until indoor fan starts running. Compressor and outdoor fan will

turn on and cold air will begin to ow from unit.

Allow unit to continue operating to cool the room and remove humidity.

After unit starts and space gets cooler, adjust thermostat to warmer temperature until compressor cycles off.

If a colder room temperature is desired, adjust thermostat to cooler temperature setting, turn compressor and both fans back on.

If a warmer room temperature is desired, adjust thermostat to warmer temperature setting. Compressor and outdoor fan stop, indoor fan switches off after sixty-second purge time has elapsed.

Place thermostat or system switch in OFF position. All operation will stop.

Troubleshooting Sensors

Table 2 - Sensor Resistance Values

Heat Pump Units — Temporary Emergency

Heating Mode

Heat pump failure, control board can be forced into electric heat mode.

This is temporary solution until heat pump system can be repaired.

Locate circuit board in control section of the unit.

Locate terminals where outdoor sensor connects to the circuit board.

Using small needle nose type pliers, disconnect one side of sensor from circuit board. A 2-stage thermostat will provide Emergency heat.

This will appear to circuit board as outdoor coil freeze condition energizing the electric resistance heater on call for heat.

See "Manual Reset Limit Switch" for resetting limit

switch if needed. See gure 33 page 35.

Figure 34 - Control Board Sensor Connections

See gure 34 for location of sensor connections to the

TROUBLESHOOTING

WARNING

Electrical shock hazard. Disconnect power to unit before servicing or accessing control compartment. Failure To follow these instructions could result in death or serious injury.

Symptom Suggestion

No heat or cooling • Check to see if unit has power and if thermostat is satised. If

thermostat is not satised, call your installing contractor or service

contractor.

Thermostat calls for cooling, but cool air is not coming out of unit.

Light on circuit board is blinking.

Circuit board light is blinking 3 or 4 times, but there is no freeze condition.

Thermostat is satised, but fan

is still running.

Thermostat calls for heat, but no heat comes out of unit.

Thermostat calls for heat while in heat pump mode, but heated air is not coming out of unit.

• Check for continuity between thermostat and unit. Verify 24Vac is present across terminals C and R.

• Verify high pressure switch located in outdoor section has not been tripped. If tripped, press switch button to restart compressor.

• Note: If evaporator fan is operational and all of above suggested procedures have been followed, and there is still no cooling being supplied by unit, contact trained heating and cooling professional.

• Circuit board uses light for diagnostic purposes. Blinking codes are as follows:

– 1 blink = normal operation – 2 blinks = compressor lockout (ASCT — Anti-short cycle timer) – 3 blinks = outdoor freeze condition – 4 blinks = indoor freeze condition – 5 blinks = simultaneous Y and W call (Straight cool units only)

• Verify sensors have not been damaged. Remove sensor wires from control board and make resistance measurements, compare to following sensor resistances. Indoor and outdoor coil sensor wires are labeled, as is control board.

– 77°F = 10KOhms – 50°F = 19.9KOhms – 35°F = 30KOhms – 30°F = 34.4KOhms

• If thermostat is set to auto mode, once thermostat is satised, fan will stay energized for extra 60 seconds to purge unit of excess cool or warm air in plenum.

• If thermostat fan switch is set to ON, fan will stay energized regardless

of whether thermostat is satised or not. Only way to turn fan off is to

turn unit off or turn thermostat fan switch to AUTO.

• Units equipped with electric heaters have temperature limit switch to prevent electric heater from reaching unsafe temperatures. If after calling for heating, heater is not energized, check for continuity across limit. If limit is open, replace with equivalent limit switch.

• Verify unit has power or thermostat has been satised. If unit has power

and thermostat is satised, turn thermostat few degrees above room

temperature.

• While in heat pump mode, verify thermostat is not energizing O terminal. Retroaire units are designed to work in heat pump mode when 24Vac is present across Y and C. Verify heat pump jumper on control board is jumping two pins labeled “HP”. See control board jumper locations,

gure 29, Page 29.

• Verify there are no freeze conditions. Refer to blinking codes question above for more information.

Have qualied technician conduct troubleshooting

procedures.
