Easy to Install, Service and Maintain

Because today’s owners are very costconscious when it comes to service and maintenance, theTrane 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 MakesTesting Easy

ReliaTel requires no special tools to run the Precedent unit through its paces. Simply place a jumper betweenTest 1 andTest 2 terminals on the LowVoltage 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 withTrane 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.

Cabinet Integrity

For added water integrity, Precedent has a raised 11/8" lip around the supply and return of the downflow units to prevent water from blowing into the ductwork.

Clogged Filter/Fan Failure Switch

A dedicated differential pressure switch is available to achieve active fan failure indication and/or clogged filter indication.

These sensors allow a zone sensor service light or Integrated Comfort System to indicate a dirty filter or a fan that’s not working.The field installation charges for these valuable feedback devices often eliminate them from consideration. Factory installation can make such features a good investment.

CO2 Sensing

The CO2 sensor has the ability to monitor space occupancy levels within the building by measuring the parts per million of CO2 (Carbon Dioxide) in the air. As the CO2 levels increase, the outside air damper modulates to meet the CO2 space ventilation requirements.The CO2 sensor kit is available as a field installed accessory.

Ventilation Override Accessory

With theVentilation 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.

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 rigorousTrane requirements.

Application

Considerations

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

LowAmbient Cooling

The Precedent™ line features, with ReliaTel™ microprocessor controls, low ambient cooling down to 0°F.

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 OFTHE RETURNAIR SYSTEM SHOULD BE CONSIDEREDTO CONTROL BUILDING PRESSURIZATION.

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 localTrane 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.

PKGP-PRC003-EN

Selection

Procedures

Cooling Capacity

Step 1

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

Factors used in unit selection:

Total Cooling Load: 59 MBh

Sensible Cooling Load: 40 MBh

Airflow: 2000 cfm

Electrical Characteristics: 460/60/3

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

External Static Pressure: 0.36 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.

59 MBh / 12 MBh = approx. 5 tons

Step 3

Table PD-3 shows that a WSC060A4 has a gross cooling capacity of 63.1 MBh and 47.5 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 theTable

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.

Step 4

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:

External Static (duct system)

0.36 wg

Standard Filter 1 in.	0.09 wg
fromTable PD-23
Economizer	0.18 wg
(100% Outside Air)	fromTable
	PD-23
Electric Heater Size 6 kW	0.056 wg
fromTable PD-23

(reference “Heating Capacity” section on this page for determination of heater size)

Total Static Pressure

0.69 wg

Note:The Evaporator Fan Performance Table PD-12 has deducted the pressure drop for a 1 in. filter already in the unit (see note belowTable PD-12).Therefore, the actual total static pressure is 0.69 - 0.09 (fromTable PD-23) = 0.60 wg.

With 2000 cfm and 0.60 wg.

Table PD-46 shows .90 bhp for this unit. Note below the table gives a formula to calculate Fan Motor Heat,

2.829 x bhp + .4024 = MBH.

2.829 x .90 + .4024 = 2.95 MBH.

Now subtract the fan motor heat from the gross cooling capacity of the unit: NetTotal Cooling Capacity

= 63.1 MBH - 2.95 = 60.15 MBH.

Net Sensible Cooling Capacity

= 47.5 MBH - 2.95 = 44.55 MBH.

Step 5

Compare results to original load requirements.

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

Heating Capacity

Step 1

Calculate the building heating load using theTrane calculation form or other standard accepted method.

Step 2

Size the equipment usingTable PD-31 to match the heating loads at design conditions.

Total heating load: 50 MBH

Outdoor Ambient (Winter) 17 DB

Indoor ReturnTemperature: 70 DB

Airflow: 2000cfm

Use the integrated portion ofTable PD-31 for the WSC060A4 to determine capacity at winter design conditions.The mechanical heating portion of the heat pump will provide 32.7 MBh.

Step 3

Because 32.7 is less than the building’s required heating capacity at winter design conditions, a supplementary heater must be selected.

50 MBh-32.7 MBh = 17.3 MBh

The auxiliary eletric heat capacities are listed inTable PD-38. From the table, a 6 kW heater will deliver 20.48 MBH at 480 volts. In order to determine capacity at 460 volts, the heater voltage correction factor fromTable PD-39 must be used. Therefore, 20.48 MBH x .918 (voltage correction factor) = 18.80 MBH. A 6kW heater should be selected.

Air Delivery Selection

External static pressure drop through the air distribution system has been calculated to be 0.60 inches of water. EnterTable PD-12 for a WSC060A4 at 2000 cfm and 0.60 static pressure.The belt drive motor will give the desired airflow at a rated bhp of 0.90 and 998 rpm.
