Mounting the Controller
Note: Self-tapping sheet metal screws are not provided for mounting.
To mount the controller:
1. Remove the controller cover to access the wiring terminals and optional
damper control actuator.
2 With self-tapping sheet metal screws, mount the VV551 controller to the
VAV box using the mounting holes provided on the controller base (refer
to Figure 1).Note the following:
• If the VV551 assembly includes a damper control actuator, insert the
actuator shaft through the hole in the base and through the actuator shaft
coupling.
• If the VV551 assembly does not include a damper control actuator, a
locally supplied actuator can be mounted in the VV551 enclosure (after
removing the shelf, circuit board, and transducer); OR
The VV551 enclosure can be mounted in a location that provides access
for locally supplied actuator and wire leads. Secure the locally supplied
actuator to the damper shaft and the VAV box.
3. Next, manually rotate the damper control actuator 100% clockwise and
then manually rotate the damper shaft 100% clockwise until it is fully
closed.
4. Tighten the damper actuator coupling against the damper shaft.
Wiring
Prior to wiring, note the following guidelines:
• All wiring must comply with National Electrical Code™ (NEC) and local
codes.
• If providing a new transformer for power, use a UL-listed Class 2 power
transformer that supplies a nominal 24 Vac (21–27 Vac). The transformer
must be sized to provide adequate power to the VV551 controller (4 VA)
and output devices, including relays and actuators (a maximum of 12
VA per controller).
• Recommended wire size for AC power is 16 AWG copper wire.
• The VV5551 controller can use up to four binary outputs (maximum) at
any time.
WARNING
Hazardous voltage!
Disconnect all electric power, including remote disconnects, before servicing.
Follow proper lockout/tagout procedures to ensure the power cannot be
inadvertently energized. Failure to disconnect power before servicing could result
in death or serious injury.
CAUTION
Injury and Equipment Damage
Ensure t hat the 24Vac transformer is properly grounded. Failure to do so may
result in personal injury and/or damage to equipment.
Complete input/output wiring before applying power to the controller. Failure to
do so may cause damage to the controller or power transformer due to
inadvertent connections to power circuits. Do not share 24 Vac between
controllers. Failure to do so may cause controller damage.
Wiring AC Power to the Controller
To connect AC power to the controller:
• Perform wiring as shown in Figure 2
Wiring the Actuator (Locally Supplied)
To wire the actuator:
1. Locate the supplied actuator cable.
2. Plug in the cable to the actuator 6-pin connector (J1) as shown in Figure 2
Note: Match receptacle 6 on the cable connector with pin 1 on the board
actuator J1 connector.
3. Attach the connectors on the actuator cable to the actuator as shown.
Note: The controller operates with floating (tri-state) control. If necessary,
the connectors that are attached to the actuator cable leads can be cut off
to enable direct connection to the locally supplied actuator wire leads.
Note: Refer to Figure 2 for wiring hot water and electric heat.

Wiring Communication Link
The Tracer VV551 VAV controller communicates with the building automation system and with other controllers over a LonTalk® communication link. Comm5 is the Trane implementation of LonTalk® protocol. For instructions on
LonTalk® communication wiring, refer to the Tracer Summit™ V17 Daily Operations Guide, BMTX-SVU01 or to the installation manual for the applicable building automation system.
Input/Output Terminal Wiring
The input/output wiring terminals for the VV551 controller are a combination of fixed function and application-specific connections. All input/output terminal wiring for the VV551 controller must meet the following requirements:
• All wiring must be in accordance with the National Electrical Code™ (NEC) and local codes
• Use only 18–22 AWG, stranded, tinned-copper, unshielded, twisted-pair wire
• Binary input and output wiring should be a maximum length of 300 ft (100 m)
• Analog input and output wiring should be a maximum length of 300 ft (100 m)
• Do not run input/output wires in the same wire bundle with any A/C power wires
• A pressure sensor can be connected with up to 300 feet of tubing and up to 60 feet of wire
The following tables describe input/output terminals, ratings, and the heat/fan output configurations by application.
