Useful formulas:Minimum Circuit Ampacity (MCA) EquationMCA = (motor amps + heater amps) x 1.25

Maximum Overcurrent Protection (MOP) EquationMOP = (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.

UNIT CONTROLS SEQUENCE OFOPERATIONThe controller will start and run the fancontinuously during the occupiedmode and intermittently during theunoccupied mode. Upon a further callfor heat, any hot water or electric heatassociated with the unit is enabled.

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 sensor isrequired.

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 an

override button to change the individualcontroller from unoccupied to occupiedmode. The override button has a cancelfeature that will return the system tounoccupied. Wired zone sensors utilizea thermistor to vary the voltage outputin response to changes in the zonetemperature. Wiring to the UCMcontroller 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, butdo so using radio transmittertechnology. Therefore with wireless,wiring from the zone sensor to the UCMis unnecessary.

Digital Display Zone Sensor withLiquid Crystal Display (LCD)—Thedigital display zone sensor contains asensing element, which sends a signalto the UCM. A Liquid Crystal Display(LCD) displays setpoint or spacetemperature. Sensor buttons allow theuser to adjust setpoints, and allow spacetemperature readings to be turned on oroff. The digital display zone sensor alsoincludes a communication jack for usewith a portable edit device, and anoverride button to change the UCMfrom unoccupied to occupied. Theoverride button has a cancel feature,which returns the system tounoccupied mode.

Trane LonTalk—The controller isdesigned to send and receive data usingSCC LonTalk profile. Current unit statusconditions and setpoints may bemonitored 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—The controller consists of a circuit boardthat offers basic VAV unit operation andadditional override functions andoperates using 24 VAC power. The




controller 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 thermistorto vary the voltage output in responseto changes in the zone temperature.Connections to the VAV unit circuitboard are made using standard three-conductor thermostat wire. Thesetpoint adjustment range is 63–85ºF(17–29°C). The sensor is available intwo models. One model has aconcealed, internally-adjustablesetpoint. The other model has anexternally-adjustable setpoint.
