NOTES:
1. The FN3 line voltage enclosure is an ETL listed option.
The FN3 was developed for Nailor fan powered terminal
units in order to help meet NEC clearance requirements.
Standard enclosures are mounted on the side of the
unit and effectively add 42" (1067) to the terminals
width footprint. Very often there is insufficient clearance
in the ceiling plenum due to physical obstructions to
accommodate this. The FN3 provides flexibility in that it
may be field positioned in any orientation that provides the
NEC clearance requirement.
2. The FN3 Line voltage enclosure ships loose with a 48"
(1219) flexible conduit connection to the terminal unit. The
enclosure should be field mounted either on or remote
from the terminal unit in a position that meets (NEC)
clearance requirements.
The controls enclosure is supplied with mounting angles,
which ship loose for field attachment.

TYPE: FIBERGLASS DUAL DENSITY INSULATION
DESCRIPTION
Tuf-Skin®dual-density fiberglass insulation is the most widely-used insulation for HVAC equipment applications. The
combination of high-density skin and low-density core provides high acoustical values in the high and low frequency
ranges normally encountered in HVAC equipment.
Application. Tuf-Skin®provides effective thermal and acoustical control in air conditioning and heating equipment.
Advantage. The porosity and inherent structure of the flame-attenuated glass fiber blankets are highly effective in
reducing thermal transfer.

TYPE: SOLID METAL LINER
(DOUBLE WALL CONSTRUCTION)
Nailor Industries Inc. reserves the right to change any information concerning product or pricing without notice.
A Solid metal liner completely isolates the standard insulation and its raw edges from the airstream within the terminal.
The solid metal liner option, also referred to as double wall construction, offers excellent protection against exposure of
fiberglass particles to the airstream. This option is ideal for applications where Indoor Air Quality (IAQ) is a concern and
where terminals will be wiped down and cleaned on a regular basis. This option is also resistant to moisture.

Nailor has independently tested and cataloged their dual duct sound data based upon the use of Steri-Liner (high
density foil back insulation) rather than standard dual density fiberglass insulation as used in the above terminal units.
This is because it is the most popular specification for dual duct terminals, where IAQ is frequently a concern. Solid
metal liner is acoustically reflective in a manner similar to Steri-Liner. The cataloged data may therefore be used
without correction when a solid metal liner is required.

CONTROL SEQUENCE 1P3 • VAV COOLING (CONTINUOUS
OPERATION) • DA/NO • 3000 CONTROLLER
Sequence of Operation:
The unit fan will deliver a constant volume to the space at all times. With space
temperature at set point, unit delivers minimum cooling airflow and maximum
induced plenum air.
On a rise in space temperature, the thermostat regulates the controller to
increase primary airflow. As more cold air is supplied to the fan section, less
warm air is induced from the ceiling plenum.
When the space temperature is warm, the primary air damper is controlling at
the maximum airflow setting (usually the same as the fan volume setting and
no plenum air is induced).
As the space temperature decreases, the damper modulates back towards
the minimum airflow setting and as less cold air is supplied to the fan section,
more warm air is induced. If room temperature continues to drop, minimum
primary airflow is maintained.
Primary airflow is held constant in accordance with thermostat demand. Any
changes in volume due to static pressure fluctuations are sensed and
compensated for, resulting in pressure independent control.
Note:
Constant volume series terminal fans should be electrically or pneumatically
field interlocked with the central fan system, to prevent backflow of primary
air into the ceiling plenum and to prevent possible backward rotation of the
terminal fan.

Sequence of Operation:
The unit fan will deliver a constant volume to the space at all times. With space
temperature at set point, unit delivers minimum cooling airflow and maximum
induced plenum air.
On a rise in space temperature, the thermostat regulates the controller to
increase primary airflow. As more cold air is supplied to the fan section, less
warm air is induced from the ceiling plenum.
When the space temperature is warm, the primary air damper is controlling at
the maximum airflow setting (usually the same as the fan volume setting and
no plenum air is induced).
As the space temperature decreases, the damper modulates back towards
the minimum airflow setting and as less cold air is supplied to the fan section,
more warm air is induced. If room temperature continues to drop, minimum

CONTROL SEQUENCE A1 • COOLING (CONTINUOUS
OPERATION)
Sequence of Operation:
Fan runs continuously, providing constant volume to the space. With room
temperature at set point, unit delivers minimum cooling airflow and maximum
induced plenum air. On a rise in room temperature, the thermostat regulates
the controller/actuator to increase primary airflow. As more cold air is supplied
to the fan section, less warm air is induced from the ceiling plenum.
When the room temperature exceeds the setpoint by 2°F (1.1°C) or more,
primary airflow is maintained at the maximum setting. The maximum setting is
usually the same as the total fan volume setting.
On a decrease in room temperature, the thermostat regulates the
controller/actuator to decrease the airflow and as less cold air is supplied to
the fan section, more warm air is induced from the ceiling plenum. If room
temperature continues to drop, minimum primary airflow is maintained.
Primary airflow is held constant in accordance with thermostat demand. Any
changes in duct air velocity due to static pressure fluctuations are sensed and
compensated for, resulting in pressure independent control.
Minimum and maximum primary airflow limits are adjusted underneath the
thermostat cover.
Note:
Constant volume series terminal fans should be interlocked to be energized
ahead of or when the central system fan starts, to prevent backflow of primary
air into the ceiling plenum and to prevent possible backward rotation of the
terminal fan.

CONTROL SEQUENCE A2 • COOLING WITH MORNING WARM-UP
(CONTINUOUS OPERATION)
Sequence of Operation:
Fan runs continuously, providing constant volume to the space. With room temperature at set
point, unit delivers minimum cooling airflow and maximum induced plenum air. On a rise in
room temperature, the thermostat regulates the controller/actuator to increase primary airflow.
As more cold air is supplied to the fan section, less warm air is induced from the ceiling plenum.
When the room temperature exceeds the setpoint by 2°F (1.1°C) or more, primary
airflow is maintained at the maximum setting. The maximum setting is usually the same
as the total fan volume setting.
On a decrease in room temperature, the thermostat regulates the controller/actuator to
decrease the airflow and as less cold air is supplied to the fan section, more warm air is
induced from the ceiling plenum. If room temperature continues to drop, minimum
primary airflow is maintained.
Primary airflow is held constant in accordance with thermostat demand. Any changes in
duct air velocity due to static pressure fluctuations are sensed and compensated for,
resulting in pressure independent control.
Minimum and maximum primary airflow limits are adjusted underneath the thermostat cover.
Morning Warm-up Cycle.
A duct mounted sensor is used to measure primary air temperature. Upon sensing a
central system supply air temperature above 77°F +/– 4 (25°C +/– 2.2), the primary air
damper will drive fully open regardless of flow limit settings. The terminal fan must be
energized. Central warm air is delivered to the space.
Note:
Constant volume series terminal fans should be interlocked to be energized ahead of or
when the central system fan starts, to prevent backflow of primary air into the ceiling
plenum and to prevent possible backward rotation of the terminal fan.

CONTROL SEQUENCE A5
COOLING WITH NIGHT CYCLE
Sequence of Operation:
Day/Occupied Cycle:
The terminal fan is interlocked by way of a positive pressure airflow switch, which
automatically energizes the fan upon sensing central system start up.
With room temperature at set point, unit delivers minimum cooling airflow and
maximum induced plenum air. On a rise in room temperature, the thermostat regulates
the controller/actuator to increase primary airflow. As more cold air is supplied to the
fan section, less warm air is induced from the ceiling plenum.
When the room temperature exceeds the setpoint by 2°F (1.1°C) or more, primary
airflow is maintained at the maximum setting. The maximum setting is usually the same
as the total fan volume setting.
On a decrease in room temperature, the thermostat regulates the controller/actuator to
decrease the airflow and as less cold air is supplied to the fan section, more warm air
is induced from the ceiling plenum. If room temperature continues to drop, minimum
primary airflow is maintained. An increase in room temperature reverses the sequence.
Primary airflow is held constant in accordance with thermostat demand. Any changes
in duct air velocity due to static pressure fluctuations are sensed and compensated for,
resulting in pressure independent control.
(Minimum and maximum primary airflow limits are adjusted underneath the thermostat cover).
Night/Unoccupied Cycle.
Airflow switch de-energizes fan upon loss of primary (central) air.
Upon a call for heat, the thermostat will override the airflow switch and will cycle the
unit fan intermittently to maintain setpoint temperature.
