Upon a further call for heat, any hot water or electric heat associated with the unit is enabled. DIRECT DIGITL CONTROLS DDC ctuator Trane 3-wire, 24-VC, floating-point control actuator with linkage release button. Torque is 35 in-lb minimum and is non-spring return with a 90-second drive time. Travel is terminated by end stops at fully-opened and -closed positions. n integral magnetic clutch eliminates motor stall. Direct Digital Controller The microprocessor based terminal unit controller provides accurate, pressureindependent control through the use of a proportional integral control algorithm and direct digital control technology. The controller, named the Unit Control Module (UCM), monitors zone temperature setpoints, zone temperature and its rate of change, and valve airflow using a differential pressure signal from the pressure transducer. dditionally, the controller can monitor either supply duct air temperature or CO 2 concentration via appropriate sensors. The controller is provided in an enclosure with 7/8" (22 mm) knockouts for remote control wiring. Trane UCM zone sensor is required. DDC Zone Sensor The UCM controller senses zone temperature through a sensing element located in the zone sensor. In addition to the sensing element, zone sensor options may include an externally-adjustable setpoint, communications jack for use with a portable edit device, and an override button to change the individual controller from unoccupied to occupied mode. The override button has a cancel feature that will return the system to unoccupied. ired zone sensors utilize a thermistor to vary the voltage output in response to changes in the zone temperature. iring to the UCM controller must be 18- to 22-awg. twisted pair wiring. The setpoint adjustment range is 50 88ºF (10 31 C). Depending upon the features available in the model of sensor selected, the zone sensor may require from a 2-wire to a 5-wire connection. ireless zone sensors report the same zone information as wired zone sensors, but do so using radio transmitter technology. Therefore with wireless, wiring from the zone sensor to the UCM is unnecessary. Digital Display Zone Sensor with Liquid Crystal Display (LCD) The digital display zone sensor contains a sensing element, which sends a signal to the UCM. Liquid Crystal Display (LCD) displays setpoint or space temperature. Sensor buttons allow the user to adjust setpoints, and allow space temperature readings to be turned on or off. The digital display zone sensor also includes a communication jack for use with a portable edit device, and an override button to change the UCM from unoccupied to occupied. The override button has a cancel feature, which returns the system to unoccupied mode. Trane LonTalk The controller is designed to send and receive data using SCC LonTalk profile. Current unit status conditions and setpoints may be monitored and/or edited from any of several LonTalk-compatible systemlevel controllers NLOG ELECTRONIC CONTROLS nalog ctuator Trane 3-wire, 24-VC, floating-point control actuator with linkage release button.
