Features and Benefits

Easy to Install, Service and Maintain

Because today’s owners are very costconscious when it comes to service and maintenance, the Trane Precedent was designed with direct input from service contractors. This valuable information helped to design a product that would get the serviceman off the job quicker and save the owner money. Precedent does this by offering:

Quality and Reliability

ReliaTel™ Controls (LCI-R)

ReliaTel controls provide unit control for heating, cooling and ventilating utilizing input from sensors that measure outdoor and indoor temperature.

Quality and Reliability are enhanced through ReliaTel control and logic:

—prevents the unit from short cycling,

considerably improving compressor life.

—ensures that the compressor will run

for a specific amount of time which allows oil to return for better lubrication, enhancing the reliability of the compressor.

Precedent with ReliaTel reduces the number of components required to operate the unit, thereby reducing possibilities for component failure.

ReliaTel Makes Installing and Servicing Easy

ReliaTel eliminates the need for field installed anti-shortcycle timer and time delay relays. ReliaTel controls provide these functions as an integral part of the unit. The contractor no longer has to purchase these controls as options and pay to install them.

The wiring of the low voltage connections to the unit and the zone sensors is as easy as 1-1, 2-2, and 3-3. This simplified system makes wiring easier for the installer.

ReliaTel Makes Testing Easy

ReliaTel requires no special tools to run the Precedent unit through its paces. Simply place a jumper between Test 1 and Test 2 terminals on the Low Voltage Terminal Board and the unit will walk through its operational steps automatically. — The unit automatically returns control to the zone sensor after stepping through the test mode a single time, even if the jumper is left on the unit.

As long as the unit has power and the “system on” LED is lit, ReliaTel is operational. The light indicates that the controls are functioning properly.

ReliaTel features expanded diagnostic capabilities when utilized with Trane Integrated Comfort™ Systems.

Some zone sensor options have central control panel lights which indicate the mode the unit is in and possible diagnostic information (dirty filters for example).

Other ReliaTel Benefits

The ReliaTel built-in anti-shortcycle timer, time delay relay and minimum “on” time control functions are factory tested to assure proper operation.

ReliaTel softens electrical “spikes” by staging on fans, compressors and heaters.

Intelligent Fallback is a benefit to the building occupant. If a component goes astray, the unit will continue to operate at predetermined temperature setpoint.

Intelligent Anticipation is a standard ReliaTel feature. It functions continuously as ReliaTel and zone sensor(s) work together in harmony to provide much tighter comfort control than conventional electro-mechanical thermostats.

The same ReliaTel Board fits all Precedent Packaged Gas/Electrics, Cooling with Electric Heat, and Heat Pump models. This provides standardization of parts for contractors. Less money is tied up in inventory with ReliaTel.

Electromechanical Controls

For the simpler job that does not require a building automation system, or expanded diagnostics capabilities, Precedent offers electromechnical controls. This 24-volt control includes the control transformer and contactor pressure lugs for power wiring.

Power Exhaust Option

This option is available on downflow units and provides exhaust of the return air, when using a downflow economizer, to maintain proper building pressurization. Great for relieving most building overpressurization problems.

Progressive Tubular Heat Exchanger

The compact cabinet features a tubular heat exchanger in low, medium and high heat capacities. The heat exchanger is fabricated using stainless steel burners and corrosionresistant aluminized steel tubes as standard on all models. It has an induced draft blower to pull the gas mixture through the burner tubes. The heater has a direct spark ignition system which doubles as a safety device to prove the flame. Gas electric Precedent models exceed all California seasonal efficiency requirements. They also perform better than required to meet the California NOx emission requirements.

Quick-Access Panels

Remove two screws for access to the standardized internal components and wiring.

Quick-Adjust Idler Arm

With the Quick-Adjust Idler Arm, the belt and sheaves can be quickly adjusted without moving the mounted fan motor. The result is a major savings in time and money.

When Trane’s changeover VAV System for light commercial applications is coupled with Precedent, it provides the latest in technological advances for comfort management systems and can allow thermostat control in every zone served by VariTrac.

Ventilation Override Accessory

With the Ventilation Override Accessory installed, the unit can be set to transition to up to 3 different pre-programmed sequences for Smoke Purge, Pressurization, and Exhaust. The transition occurs when a binary input on the RTOM is closed (shorted). This would typically be a hard wired relay output from a smoke detector or fire control panel. The ventilation override kit is available as a field installed accessory.

Zone Sensors

Available in programmable, automatic and manual styles. Precedent offers ultimate flexibility. Units are built to order in our standard “shortest in the industry” ship cycle time.

VariTrac™

Rigorous Testing

All of Precedent’s designs were rigorously rain tested at the factory to ensure water integrity.

Actual shipping tests were performed to determine packaging requirements. Units were test shipped around the country to determine the best packaging. Factory shake and drop tests were used as part of the package design process to help assure that the unit arrives at the job site in top condition.

Rigging tests include lifting a unit into the air and letting it drop one foot, assuring that the lifting lugs and rails hold up under stress.

We perform a 100% coil leak test at the factory. The evaporator and condenser coils are leak tested at 200 psig and pressure tested to 450 psig.

All parts are inspected at the point of final assembly. Sub-standard parts are identified and rejected immediately.

Every unit receives a 100% unit run test before leaving the production line to make sure it lives up to rigorous Trane requirements.

Precedent has the features and benefits that make it first class in the light commercial rooftop market.

RT-PRC006-EN10

Application Considerations

Application of this product should be within the cataloged airflow and cooling considerations.

Low Ambient Cooling

The Precedent™ line features, with ReliaTel™ microprocessor controls, low ambient cooling down to 0°F. With electromechanical controls, Precedent features low ambient cooling to 40°F. The following options need to be included/ considered when low ambient applications are required: continuous fan operation, crankcase heaters, thermal expansion valves, frostat. Contact your local Trane Representative for more assistance with low ambient cooling applications.

Barometric Relief

This product line offers an optional barometric relief damper for use in conjunction with economizer option. This accessory consists of gravity dampers which open with increased pressure. As the building air pressure increases, the pressure in the unit return air section also increases, opening the dampers and relieving the conditioned space.

NOTE: THE EFFECTIVENESS OF BAROMETRIC RELIEF DAMPER DURING ECONOMIZING OPERATION IS SYSTEM RELATED.

PRESSURE DROP OF THE RETURN AIR SYSTEM SHOULD BE CONSIDERED TO CONTROL BUILDING PRESSURIZATION.

Heating Operation

The heat exchanger is manufactured with aluminized steel. To prevent condensation within the heat exchanger, do not exceed 50% outside air or a minimum mixed air temperature of 40°F.

Condensate Trap

The evaporator is a draw-thru configuration. A trap must be field provided prior to start-up on the cooling cycle.

Clearance Requirements

The recommended clearances identified with unit dimensions should be maintained to assure adequate service maximum capacity and peak operating efficiency. Actual clearances which appear inadequate should be reviewed with the local Trane sales personnel.

Unit Pitch

These units have reversible sloped condensate drain pans. Units must be installed level, any unit slope must be toward the side of unit where condensate drain is connected.

Selection Procedures

Cooling Capacity

Step 1

Calculate the building’s total and sensible cooling loads at design conditions. Use the Trane calculation methods or any other standard accepted method.

Factors used in unit selection:

Total Cooling Load: 58 MBh

Sensible Cooling Load: 40 MBh

Airflow: 2000 cfm

Electrical Characteristics: 460/60/3

Summer Design Conditions: Entering Evaporator Coil: 80 DB, 67 WB Outdoor Ambient: 95

External Static Pressure: 0.52 in. wg

Downflow Configuration

High Efficiency

Economizer

Step 2

As a starting point, a rough determination must be made of the size of the unit. The final selection will be made after examining the performance at the given conditions. Divide the total cooling load by nominal BTUH per ton (12 MBh per ton); then round up to the nearest unit size.

58 MBh / 12 MBh = approx. 5 tons

Step 4

Verify the unit will have enough capacity to meet the building requirements by determining the net capacity, which includes heat generated by the fan. In order to select the correct unit which meets the building’s requirements, the fan motor heat must be deducted from the gross cooling capacity. The amount of heat that the fan motor generates is dependent on the effort by the motor cfm and static pressure. To determine the total unit static pressure add the external static pressure to the additional static created by the added features:

External Static (duct system)

0.52 wg

Standard Filter 1 in. 0.06 wg from Table PD-89

Economizer 0.18 wg

(100% Outside Air) from Table

PD-89

Total Static Pressure 0.76 wg

Note: The Evaporator Fan Performance Table PD-64 has deducted the pressure drop for a 1 in. filter already in the unit (see note below Table PD-64). Therefore, the actual total static pressure is 0.76 -

0.06 (from Table PD - 89) = 0.70 wg.

With 2000 cfm and 0.70 wg., Table PD-64 shows 1.07 bhp for this unit. Note below the table gives a formula to calculate Fan Motor Heat,

Heating Capacity

Step 1 — Calculate the building heating

load using the Trane calculation form or other standard accepted method.

Step 2 — Size the system heating capacity to match the calculated building heating load. The following are building heating requirements: a. Total heating load of 60.0 MBh b. 2000 cfm c. Fuel - Natural gas

For the YSC060A4 there are three heating capacities available, 60 MBh, 80 MBh and 130 MBh input models shown in Table PD-91. The output capacities of these furnaces are 48 MBh, 64 MBh and 104 MBh respectively. The medium heat model with 64 MBh best matches the building requirements, indicating a YHC060A4*M should be selected.

Air Delivery Selection

External static pressure drop through the air distribution system has been calculated to be 0.7 inches of water. Enter Table PD-64 for a YHC060A4*M at 2000 cfm and 0.70 static pressure. The standard belt drive motor will give the desired airflow with 1.07 bhp and 1094 rpm.

Accessory Selection

Select accessories needed to accommodate the application.

Step 3

Examine gross capacity: Table PD-13 shows that a YHC060A4 has a gross cooling capacity of 62.4 MBh and 48.4 MBh sensible capacity at 2000 cfm and 95 DB outdoor ambient with 80 DB, 67 WB air entering the evaporator.

To Find Capacity at Intermediate Conditions Not in the Table

When the design conditions are between two numbers that are in the capacity table, interpolation is required to approximate the capacity. Note: Extrapolation outside of the table conditions is not recommended.

2.829 x bhp + .4024 = MBH.

2.829 x 1.07 + .4024 = 3.43 MBH.

Now subtract the fan motor heat from the gross cooling capacity of the unit: Net Total Cooling Capacity = 62.4 MBH - 3.43 = 58.97 MBH.

Net Sensible Cooling Capacity = 48.4 MBH - 3.43 = 44.97 MBH.

Step 5

If the performance will not meet the required load of the building’s total or sensible cooling load, try a selection at the next higher size unit.

Since reheat adds only sensible heat, follow the psychrometric chart to find the new wb temperature.

≅ 61°F wb

Consider Chart C-1. If the space relative humidity is equal to or above the space relative humidity setpoint, the Dehumidification option will:

• Energize compressor or both compressors (2 stage compressor units).

• Hot gas reheat valve is energized and hot gas is diverted to the reheat coil.

• Dehumidification/reheat is terminated when space humidity is reduced to 5% below relative humidity setpoint.

At MA’, air enters the RTU. The RTU filters, cools, and dehumidifies the air as it moves through the evaporator coil. Air leaves the evaporator coil saturated at the preset dew point condition (SA’) and is reheated by the hot gas reheat coil to deliver 76°F (SA) supply air to the space.
