SAFETY WARNING
Only qualified personnel should install and service the equipment. The installation,
starting up, and servicing of heating, ventilating, and air-conditioning equipment can
be hazardous and requires specific knowledge and training. Improperly installed,
adjusted or altered equipment by an unqualified person could result in death or
serious injury. When working on the equipment, observe all precautions in the
literature and on the tags, stickers, and labels that are attached to the equipment.

Indicates a potentially hazardous situation which,
if not avoided, could result in death or serious
injury.
CAUTION
Indicates a potentially hazardous situation which,
if not avoided, could result in minor or moderate
injury. It could also be used to alert against unsafe
NOTICE
Indicates a situation that could result in
equipment or property-damage only accidents.

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
.
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
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
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
for wiring hot water and electric heat.
