Options
Power Fuse (cooling only and hot water units, and VDDF)
An optional fuse is factory-installed in the primary voltage hot leg.
Transformer (Standard on fan-powered, optional on VCCF, VCWF, VDDF)
The 50-VA transformer is factory-wired and installed in an enclosure with 7/8" (22 mm) knockouts
to provide 24 VAC for controls.
Wireless Zone Sensor/Receiver
Factory mounted Receiver with field mounted sensor accessory eliminates the need for the wiring
between the zone sensor and unit level controller.
Disconnect Switch (Optional on VCCF, VCWF, VDDF)
Disengages power.
DDC Retrofit Kit (VRTO)
The kit consists of a Trane DDC Unit Control Module (UCM) VAV terminal unit controller and a
pressure transducer installed in a metal enclosure. The mechanical specifications of accessories
such as DDC zone sensors, hot water valves, and transformers are found elsewhere in this section.
Retrofit Kit Options
Flow Bar Sensor
The flow bar sensor is a multiple-point, averaging, pitot tube type flow sensor. It is intended for field
installation on terminal units that have no flow measurement device. The total and static pressure
outputs of the sensor are field-piped to the high and low inputs of the pressure transducer in the
retrofit kit.
Retrofit Kit Actuator
The electric actuator is a direct-coupled type actuator that utilizes three-wire, floating-point control.
The actuator is field-installed to the damper shaft and field-wired to the controller.
Trane Actuator – Actuator is rated at 4 VA at 24 VAC. Drive time is 90 seconds with 35 in.-lb (4 N-m).
Retrofit Actuator – Actuator is rated at 3 VA at 24 VAC. Drive time is 80 to 110 seconds for 0 to 35
in.-lb (0 to 4 N-m).
