WARNINGWARNING
There is a risk of electric shock. Before you make electrical
connections, disconnect.
Risk of property damage. Rotate the damper to the full-open
position before you start the air handler. If you do not to rotate
the damper to the full-open position.
!!
CAUTIONCAUTION
Before you connect the supply power to the controller,
complete the wiring and check all wiring connections. Short
circuits or improperly connected wires can damage the control-
ler and void any warranty.
!!
CAUTIONCAUTION
Do not exceed the controller electrical ratings. Exceeding
controller electrical ratings can result in permanent damage to
the controller and void any warranty.
!!
CAUTIONCAUTION

Electrostatic discharge can damage controller components.
To avoid damaging the controller, use proper electrostatic
discharge precautions during installation, setup, and servicing.
!!
CAUTIONCAUTION
To avoid property damage, before you apply power to the
system, check all wiring connections. If you wire this terminal
incorrectly, a short circuit can occur across the 24 VAC power
supply on the controller. A short circuit can cause a tripped
circuit breaker or a blown fuse. If you use a transformer with a
built-in fuse, you may need to replace the transformer.
!!
CAUTIONCAUTION
!!
IMPORTANTIMPORTANT
To avoid stripping the threads, do not overtighten the screw.
!!
IMPORTANTIMPORTANT
Use copper conductors only. Wire in accordance with local,
national, and regional regulations.
!!
IMPORTANTIMPORTANT
Only use the controller as an operating control. Design addi-
tional precautions into the control system where failure or
malfunction of the controller could lead to personal injury
or damage to the controlled equipment or other property.
Incorporate and maintain other devices that warn of or protect
against controller failure or malfunction, such as supervisory,
alarm systems, safety, or limit controls.
!!
IMPORTANTIMPORTANT
To reduce noise, interference, and ground loop problems,
connect a 24 VAC supply power to the controller and to all
other network devices so that transformer phasing is uniform
across network devices. The controller does not require an
earth ground connection. However, when you need to ground
the secondary of the 24 VAC transformer, make only one
ground connection near the transformer.
Note: When the air supply to the VAV box is below 10°C or
50°F, ensure that condensation on the VAV box, particularly on
the damper shaft, does not enter the VAV controller.
Note: EasyIO FW-VAV is not intended to support third-party
devices on an SA bus.
Note: Do not use the modular SA bus port and the SA bus
spade lug connection at the same time. Use only one connec-
tion at a time.
!!
IMPORTANTIMPORTANT
If you mount the controller to the VAV box, ensure that
the screws do not interfere with damper blade movement.
