Notes:1. Coils available with 24 VAC magnetic or mercury contactors, load carrying P.E. switches, and P.E. switch with magnetic or mercury contractors.2. Available kW increments are by 0.5 from 0.5 kW to 8.0 kW and by 1.0 kW from 9.0 to 14.0 kW.3. Each stage will be equal in kW output.4. All heaters contain an auto thermal cutout and a manual reset cutout.5. The current amp draw for the heater elements is calculated by the formula below.6. Only two stages of electric reheat available with Trane controls.

Formulas

Minimum Circuit Ampacity (MCA) Equation• MCA = (motor amps + heater amps) x 1.25

Maximum Overcurrent Protection (MOP) Equation• MOP = (2.25 x motor amps) + heater amps

General Sizing Rules:• If MOP = 15, then fuse size = 15

• If MOP = 19, then fuse size = 15 with one exception. If heateramps x 1.25 > 15, then fuse size = 20.

• If MOP ≤ MCA, then choose next fuse size greater than MCA.

• Control fusing not applicable.

• Standard Fuse Sizes: 15, 20, 25, 30, 35, 40, 45, 50, and 60.

Notes:1. Electric Heat Units - Units with Primary Voltage of 208/60/1, 208/

60/3 or 240/60/1 use 115 VAC fan motors.2. Electric Heat Units - Units with Primary Voltage of 277/60/1,

480/60/1 or 480/60/3 use 277 VAC fan motors.3. Electric Heat Units - Units with Primary Voltage of 347/60/1 or

575/60/3 use 347 VAC fan motors.4. Values are for standard, single-speed, permanent split capacitor

type motors. Consult factory for non-standard motorperformance.

5. Motor amps for 10SQ are total amps for two motors.

Useful formulas:

UNIT CONTROLS SEQUENCE OFOPERATIONThe controller continuously monitorsthe zone temperature against itssetpoint and varies the primary airflowas required to meet zone setpoints.Airflow is limited by minimum andmaximum setpoints. For a low-heightparallel unit, the controller willintermittently start the fan upon a callfor heat. Upon a further call for heat,any hot water or electric heatassociated with the unit is enabled.

1. Primary Airflow—The fan energizeswhen primary airflow drops belowthe fan setpoint airflow. The fanautomatically starts when the zonetemperature drops to the heatingtemperature setpoint.

2. Zone Temperature—The fanenergizes when the zone temperaturedrops to a selectable number ofdegrees above the heatingtemperature setpoint.

DIRECT DIGITAL CONTROLS

DDC Actuator—Trane 3-wire,24-VAC, floating-point control actuatorwith linkage release button. Torque is35 in-lb minimum and is non-springreturn with a 90-second drive time.Travel is terminated by end stops atfully-opened and -closed positions. Anintegral magnetic clutch eliminatesmotor stall.

Direct Digital Controller—Themicroprocessor based terminal unitcontroller provides accurate, pressure-independent control through the useof a proportional integral controlalgorithm and direct digital controltechnology. The controller, named theUnit Control Module (UCM), monitorszone temperature setpoints, zonetemperature and its rate of change,and valve airflow using a differentialpressure signal from the pressuretransducer. Additionally, the controllercan monitor either supply duct airtemperature or CO2 concentration viaappropriate sensors. The controller isprovided in an enclosure with 7/8"(22 mm) knockouts for remote controlwiring. A Trane UCM zone sensoris required.

DDC Zone Sensor—The UCMcontroller senses zone temperaturethrough a sensing element located inthe zone sensor. In addition to thesensing element, zone sensor optionsmay include an externally-adjustablesetpoint, communications jack for usewith a portable edit device, and anoverride button to change theindividual controller from unoccupiedto occupied mode. The override buttonhas a cancel feature that will return thesystem to unoccupied. Wired zonesensors utilize a thermistor to vary thevoltage output in response to changesin the zone temperature. Wiring to theUCM controller must be 18- to 22-awg.twisted pair wiring. The setpointadjustment range is 50–88ºF (10–31°C).Depending upon the features availablein the model of sensor selected, thezone sensor may require from a 2-wireto a 5-wire connection. Wireless zonesensors report the same zoneinformation as wired zone sensors,but do so using radio transmittertechnology. Therefore with wireless,wiring from the zone sensor to theUCM is unnecessary.

Digital Display Zone Sensor withLiquid Crystal Display (LCD)—The digital display zone sensorcontains a sensing element, whichsends a signal to the UCM. A LiquidCrystal Display (LCD) displays setpointor space temperature. Sensor buttonsallow the user to adjust setpoints, andallow space temperature readings tobe turned on or off. The digital displayzone sensor also includes a




communication jack for use with aportable edit device, and an overridebutton to change the UCM fromunoccupied to occupied. The overridebutton has a cancel feature, whichreturns the system tounoccupied mode.

Trane LonTalk—The controller isdesigned to send and receive datausing SCC LonTalk profile. Current unitstatus conditions and setpoints maybe monitored and/or edited from any ofseveral LonTalk-compatible system-level controllers.

ANALOG ELECTRONIC CONTROLS

Analog Actuator—A Trane 3- wire,24-VAC, floating-point control actuatorwith linkage release button. Torque is35 in-lb minimum and is non-springreturn with a 90-second drive time.Travel is terminated by end stops atfully-opened and -closed positions. Anintegral magnetic clutch eliminatesmotor stall.

Analog Electronic Controller—Thecontroller consists of a circuit boardthat offers basic VAV unit operationand additional override functions andoperates using 24 VAC power. Thecontroller uses a capacitive typepressure transducer to maintainconsistent air delivery regardless ofsystem pressure changes. Theenclosure with 7/8" (22 mm) knockoutsfor remote control wiring. A Traneelectronic zone sensor is required.

Analog-Electronic Thermostat—This single-temperature, wall-mountedelectronic device utilizes a thermistor tovary the voltage output in response tochanges in the zone temperature.Connections to the VAV unit circuitboard are made using standard three-conductor thermostat wire. The setpointadjustment range is 63–85ºF (17–29°C).The sensor is available in two models.One model has a concealed, internally-adjustable setpoint. The other modelhas an externally-adjustable setpoint.
