Introduction
Read this manual thoroughly before operating or
servicing this unit.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as
required. Your personal safety and the proper
operation of this machine depend upon the strict
observance of these precautions.
The three types of advisories are defined as follows:
WARNING
CAUTION
NOTICE
Indicates a potentially hazardous situation
which, if not avoided, could result in death or
serious injury.
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 practices.
Indicates a situation that could result in
equipment or property-damage only
accidents.
Important Environmental Concerns
Scientific research has shown that certain man-made
chemicals can affect the earth’s naturally occurring
stratospheric ozone layer when released to the
atmosphere. In particular, several of the identified
chemicals that may affect the ozone layer are
refrigerants that contain Chlorine, Fluorine and Carbon
(CFCs) and those containing Hydrogen, Chlorine,
Fluorine and Carbon (HCFCs). Not all refrigerants
containing these compounds have the same potential
impact to the environment. Trane advocates the
responsible handling of all refrigerants-including
industry replacements for CFCs and HCFCs such as
saturated or unsaturated HFCs and HCFCs.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or
serious injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded
field wiring poses FIRE and ELECTROCUTION
hazards. To avoid these hazards, you MUST follow
requirements for field wiring installation and
grounding as described in NEC and your local/
state/national electrical codes.
WARNING
Personal Protective Equipment (PPE)
Required!
Failure to wear proper PPE for the job being
undertaken could result in death or serious injury.
Technicians, in order to protect themselves from
potential electrical, mechanical, and chemical
hazards, MUST follow precautions in this manual
and on the tags, stickers, and labels, as well as the
instructions below:
•
Before installing/servicing this unit,
technicians MUST put on all PPE required for
the work being undertaken (Examples; cut
resistant gloves/sleeves, butyl gloves, safety
glasses, hard hat/bump cap, fall protection,
electrical PPE and arc flash clothing).
ALWAYS refer to appropriate Safety Data
Sheets (SDS) and OSHA guidelines for
proper PPE.
•
When working with or around hazardous
chemicals, ALWAYS refer to the appropriate
SDS and OSHA/GHS (Global Harmonized
System of Classification and Labelling of
Chemicals) guidelines for information on
allowable personal exposure levels, proper
respiratory protection and handling
instructions.
•
If there is a risk of energized electrical
contact, arc, or flash, technicians MUST put
on all PPE in accordance with OSHA, NFPA
70E, or other country-specific requirements
for arc flash protection, PRIOR to servicing
the unit. NEVER PERFORM ANY SWITCHING,
DISCONNECTING, OR VOLTAGE TESTING
WITHOUT PROPER ELECTRICAL PPE AND
ARC FLASH CLOTHING. ENSURE
ELECTRICAL METERS AND EQUIPMENT ARE
PROPERLY RATED FOR INTENDED
VOLTAGE.
Important Responsible Refrigerant
Practices
Trane believes that responsible refrigerant practices
are important to the environment, our customers, and
the air conditioning industry. All technicians who
handle refrigerants must be certified according to local
rules. For the USA, the Federal Clean Air Act (Section
608) sets forth the requirements for handling,
reclaiming, recovering and recycling of certain
refrigerants and the equipment that is used in these
service procedures. In addition, some states or
municipalities may have additional requirements that
must also be adhered to for responsible management
of refrigerants. Know the applicable laws and follow
them.

Introduction
WARNING
Follow EHS Policies!
Failure to follow instructions below could result in
death or serious injury.
•
•
All Trane personnel must follow the
company’s Environmental, Health and Safety
(EHS) policies when performing work such as
hot work, electrical, fall protection, lockout/
tagout, refrigerant handling, etc. Where local
regulations are more stringent than these
policies, those regulations supersede these
policies.
Non-Trane personnel should always follow
local regulations.
WARNING
Fiberglass Wool!
Exposure to glass wool fibers without all
necessary PPE equipment could result in cancer,
respiratory, skin or eye irritation, which could
result in death or serious injury. Disturbing the
insulation in this product during installation,
maintenance or repair will expose you to airborne
particles of glass wool fibers and ceramic fibers
known to the state of California to cause cancer
through inhalation.
You MUST wear all necessary Personal Protective
Equipment (PPE) including gloves, eye protection,
a NIOSH approved dust/mist respirator, long
sleeves and pants when working with products
containing fiberglass wool.
Precautionary Measures:
•
Avoid breathing fiberglass dust.
•
Use a NIOSH approved dust/mist respirator.
•
Avoid contact with the skin or eyes. Wear
long-sleeved, loose-fitting clothing, gloves,
and eye protection.
•
Wash clothes separately from other clothing;
rinse washer thoroughly.
•
Operations such as sawing, blowing, tearout, and spraying may generate fiber
concentrations requiring additional
respiratory protection. Use the appropriate
NIOSH approved respirator.
First Aid Measures:
•
Eye Contact - Flush eyes with water to
remove dust. If symptoms persist, seek
medical attention.
•
Skin Contact - Wash affected areas gently
with soap and warm water after handling.

Unit Information
Single Duct VAV Units
Typical Single Duct VAV Units
The basic unit consists of a sheet metal casing with an
air valve, which is used to modulate the air being
delivered into the occupied zone. The unit is designed
to modulate either cooling or heating air between 40°F
and 140°F (4.44°C and 60°C). Air enters the air valve
through the round or rectangular inlet and exits into
the sheet metal casing to be distributed to the zone
either through integral round outlets in the casing or
through rectangular duct attached to the discharge of
the unit.
Figure 1. Typical single duct unit; VCCF VCWF, VCEF
The basic unit can also be ordered with factorymounted electric or hot water heating coils attached to
the discharge.
These re-heat units are used primarily to reheat air-tozone temperature when the load in the occupied space
is low.
Primary air is modulated through the VariTrane™ air
valve by rotating the damper blade. All air valves have
a round/rectangular inlet for easy fit-up with incoming
duct work.
VAV-SVX08R-EN

Unit Information
Dual-Duct VAV Units
Dual-duct units provide two air valves: one as heating
primary air and the other as cooling primary air. Both
discharge into the common outlet, which leads to the
zone being controlled. See Figure 2, p. 16.
Units are provided with a slip and drive rectangular
duct connection or can be ordered with integral outlet
plenum.
Sequencing of hot and cold air valve is dependent on
job requirements. One typical control is valves working
in conjunction to respond to zone temperature.
Fan-Powered/Fan-Powered LowHeight VAV Units
VariTrane™ fan-powered and low-height fan-powered
units can be either parallel or series, with or without reheat. Refer to the following figures.
Typical Fan-powered Units
Figure 3. Parallel fan-powered terminal unit (top) and
series fan-powered terminal units (bottom)
When the cooling valve becomes fully closed or
reaches a specified minimum, the heating valve will
begin to modulate or vice versa. The typical result is
that air flowing to the zone varies from maximum
down to a minimum and back up to maximum as load
varies and controls would cause one air valve to close
and the other to open.
Another typical application is when the unit provides a
constant volume to the zone. When the zone sensor is
tied directly to the heating valve, it will modulate the
heating valve according to the zone temperature.
When the heating valve is fully closed or there is a call
for cooling in the zone, the cooling valve will be at
constant supply. As the space becomes too cool, the
heating valve will modulate open, decreasing the
cooling valve flow. The typical result is that the air
flowing into the zone stays at a constant flow whether
the unit is heating or cooling.

fan is turned on as the first stage of heat. The fan
delivers plenum air from above the occupied space to
the unit outlet, which is mixed with primary air and
delivered to the occupied space.
N o t e : Either the fan, the air valve, or both can deliver
airflow into the occupied space. In order to
prevent primary airflow from exiting through the
fan when the fan is not running on a parallel unit,
a back draft damper is provided. When the fan is
not running, the efficiency of this system is the
same as a standard single-duct VAV unit.
Typically, the control systems applied to parallel units
cause the air valve to close to zero or a minimum flow
before the fan is activated. After the fan is activated, the
optional heat will be activated upon further reduction
in zone temperature. Therefore, minimal primary air is
mixed with the heated air.

in. w.g. and sizes 06SQ and 07SQ were tested at .15 in.
w.g. Units are not designed to operate without ducts
and below these tested static pressures.
N o t e : Fan-powered units are available with rectangular
discharge connection only. The optional heater
is mounted on the discharge of the unit. Hot
water coils are connected to either the plenum
inlet or on the discharge on parallel units, and to
the discharge of series units.
Chilled Water Sensible Cooling
Terminal Units
Chilled water sensible cooling terminal units are
available with or without re-heat. Refer to the following
figures.
Figure 7. Chilled water sensible cooling unit
The fan on a series unit runs continuously whenever
the main air handler unit is in operation. There are
three (3) methods to start the fan: 1) remotely, 2) by a
duct pressure switch, or 3) by a combination of both.
The particular fan control method may vary from unit
to unit, depending upon job needs.
Typically, heater is off while air valve modulates
primary air and responds to zone temperature. If zone
temperature decreases to the point where a decrease in
primary air will not maintain the desired temperature,
the re-heat will be activated to increase the
temperature of the discharge air.
On a parallel unit, the VariTrane™ air valve delivers
primary cooling air to the unit outlet. When the space
temperature decreases beyond air valve control, the

The function of the Trane chilled water sensible cooling
terminal units is a little different than traditional VAV
18
Terminal Units. These terminal units are part of a
s y s t e m that uses a dedicated outdoor-air unit to
distribute outdoor air to an air valve on each terminal
unit to meet the ventilation requirements of the zone.
Each terminal unit is also equipped with a cooling coil
mounted on the plenum inlet. Recirculated air from the
plenum (or directly from the occupied space) is drawn
in through this cooling coil by the local fan. This cooled
air is then mixed with the conditioned (cooled,
dehumidified, heated, or humidified) outdoor air from
the dedicated OA unit, and distributed through the
downstream ductwork to the zone.
In most applications, the water supplied to this local
cooling coil is controlled to a temperature above the
dew point in the zone. This avoids moisture in the air
from condensing on the coil, so it operates dry and
provides only sensible cooling. All the
dehumidification must then be provided by the
dedicated outdoor-air unit. Trane chilled water sensible
cooling terminal units are built with a drip pan located
beneath the cooling coil, with a moisture sensor
installed in it, to detect and prevent any moisture from
getting on the ceiling beneath the units or into the
occupied space below. These terminal units can be
configured with either a hot water coil or electric heater
mounted at the unit discharge.

Unit Installation
WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge
capacitors before servicing could result in death or
serious injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper
lockout/tagout procedures to ensure the power
cannot be inadvertently energized. For variable
frequency drives or other energy storing
components provided by Trane or others, refer to
the appropriate manufacturer’s literature for
allowable waiting periods for discharge of
capacitors. Verify with a CAT III or IV voltmeter
rated per NFPA 70E that all capacitors have
discharged.
WARNING
Proper Structural Support Required!
Failure to ensure proper structural ceiling support
could result in unit falling from its location which
could result in death or serious injury.
Ceiling structure must be strong enough to
support the weight of the unit and any
accessories. If unsure, check with a structural
engineer.
Due to their weight, the VAV terminal units should be
suspended from the uppermost ceiling, independent of
the false ceiling grid. In fact, VAV terminal units are
primarily designed for installation in the plenum space
between the upper most ceiling and the false ceiling
grid below it. See “Weights,” p. 28 for unit weights.
Suspension devices are to be supplied by the installer.
Units must be installed level and upright. Failure to
level the unit properly may prevent proper operation of
the controls and/or terminal unit. Units are not
designed to be installed vertically. Consequently, this
will also void the U.L. ratings and any warranty on the
unit.
Single-Duct VAV Units
Figure 10.
Single-duct hanging recommendations
Depending upon the size and weight of the single-duct
unit, it may be capable of being supported by the
ductwork that is connected to it. No hanger brackets
are provided on these units since the unit should be
supported by means of a hanger strap. The hanger
strap should be secured directly to the unit casing as
shown above.
•
For cooling only single-duct units or single-duct
units with hot water coil, the unit may be rotated
180° for opposite side connections.
•
For units with electric heat, the unit can be flipped
to either RH or LH connection orientation if model
number digit 22 Electrical Connections = F.
Dual-Duct VAV Units
Dual-duct units should be supported by either hanger
straps or by using a threaded rod in conjunction with
the hanger brackets that are provided on the unit.

Discharge Duct Temperature
Sensor Installation
1. Determine the sensor mounting location on the
duct. The sensing element is located within 1 inch
(25mm) of the end of the sensing probe, and it
should be located in the air stream typical of the
temperature requiring sensing.
Note: This process is to be used for control
sequences that involve Discharge Air
Temperature (DAT) control.
2. Use the mounting plate supplied as a template (or
refer to Figure 18, p. 25 for duct mounting
dimensions) for mounting hole location.
Several Tracer® UC210/UC400 control sequences
perform direct DAT control of the VAV unit when both
modulating unit heat and modulating ECM fan are
present or when modulating unit heat is present on a
non-fan-powered VAV unit. Supported modulating unit
heat options include modulating hot-water and SCRcontrolled electric heat. In these Tracer® UC210/UC400
control sequences, the DAT is a control input to the unit
controller.

Chilled Water Sensible Cooling
Terminal Units Moisture Sensor
Installation
In most applications, the water supplied to this local
cooling coil is controlled to a temperature above the
dew point in the zone. This avoids moisture in the air
from condensing on the coil, so it operates dry and
provides only sensible cooling. All dehumidification
must then be provided by the dedicated outdoor-air
unit. Trane chilled water sensible cooling terminal units
are built with a drip pan located beneath and above the
cooling coil, with a moisture sensor installed, to detect
and prevent any moisture from getting on the ceiling
beneath the units or into the occupied space below.
Sensible cooling units are designed so that the unit can
be flipped 180 degrees for right and left hand
orientation. They are configured as left hand from the
factory with a moisture sensor installed to a bracket on
the bottom of the drip pan. If installed as a right hand
unit the moisture sensor will need to be moved to the
bracket provided (shown in the following figure) so that
the moisture sensor is on the bottom of the unit for
proper moisture detection.
Figure 19. Moisture sensor installation and additional
bracket shown in cooling coil drip pan
side of the water coil. All other single-duct and dualduct units are provided without access, as all
functioning components are external to the unit.
•
Fan-powered terminals are provided with a sliding
side access.
•
Low-height terminal units have a removable
bottom panel.
Clearances
For proper service, it is recommended that at least 3
inches” of side clearance be provided to service and
access single-duct and dual-duct terminals units.
•
Fan-powered VAV units have a plenum inlet that
must be clear of obstructions. Allow at least 36
inches of clearance in front of the side access and
plenum opening.
•
Low-height fan-powered terminals require the
same plenum clearance requirement that applies to
the standard fan-powered units. However the
access to the internal components is located on the
bottom of the unit.
•
Fan-powered VAV units with Suppressor attenuator
requires at least 4.5 inches (6 inches preferred)
clearance above the plenum opening.
•
Fan-powered VAV units with Thinline Suppressor
attenuator requires at least 4.5 inches (6 inches
preferred) clearance at plenum openings.
It is also recommended that 6 inches of clearance be
provided to the top and bottom of all the units.
N o t e : The minimum clearance for controls and heater
controls should be 36 inches for all models
except units with 575-volt electric heaters, which
require 48 inches of clearance. NEC™ and/or
local codes override all clearance requirements.
Mounting Actuator
I m p o r t a n t : When installing or replacing the actuator
tighten the actuator set screw per the
manufacturer’s instructions. Failure to
follow the manufacturer’s specifications
may result in unit malfunction.
Trane offers a factory-mounted actuator with a 90second drive time. The actuator drives 1° per second. A
field-installed actuator may be used if desired. The
actuator shaft has a 0.5 inch diameter and is designed
to travel clockwise to close the damper and counterclockwise to open the damper. There is an indicator on
the end of the actuator shaft that can be used to
determine the position of the damper.

action is determined by the auxiliary temperature
sensor located on TB3-5 and TB3-6 terminals on the
UCM board. In order for the auxiliary sensor to
determine the control action (heat, cool) it must be
located in the supply duct, upstream of the VAV unit.
The auxiliary temperature is then compared to the zone
temperature. If the supply air temperature is 10
degrees above the zone temperature, then the control
action will be heat. If the supply air temperature is less
than or equal to the zone temperature, then the control
action will be cool. If the supply air temperature is
between the zone temperature and the zone

Stand-alone VV550 LonTalk Control
When there is no communication to the VV550 control
and the unit is in the stand-alone mode the control

through the Inputs Tab of Analog Input 4 as Primary
Supply Air Sensor. In order for the auxiliary sensor to
determine the control action (heat, cool) it must be
located in the supply duct, upstream of the VAV unit.
The auxiliary temperature is then compared to the zone
temperature. If the supply air temperature is 10
degrees above the zone temperature, then the control
action will be heat. If the supply air temperature is less
than or equal to the zone temperature, then the control
action will be cool. If the supply air temperature is
between the zone temperature and the zone

Stand-alone UC400
When there is no communication to the UC400 control
and the unit is in the stand-alone mode the control
action is determined by the auxiliary temperature

This input may have to be changed from AI4 (Discharge
Air Input) as wired from the factory. In order for the
auxiliary temperature sensor to determine the control
action (heat, cool) it must be located in the supply duct,
upstream of the VAV unit. The auxiliary temperature is
then compared to the zone temperature. If the supply
air temperature is 10°F above the zone temperature,
then the control action will be heat. If the supply air
temperature is less than or equal to the zone

action is determined by the auxiliary temperature
sensor located on AI3 terminals on the UC210 control.
From the factory, this input is configured for discharge
air temperature and needs to be field reconfigured as
supply air temperature using Tracer® TU. In order for
the auxiliary temperature sensor that is configured for
supply air temperature to determine the control action
(heat, cool) it must be located in the supply duct,
upstream of the VAV unit. The supply air temperature
is then compared to the zone temperature. If the supply
air temperature is 10°F above the zone temperature,
then the control action will be heat. If the supply air
temperature is less than or equal to the zone
temperature, then the control action will be cool. If the
supply air temperature is between the zone
temperature and the zone temperature +10°F (5.5°C)
[zone temperature < supply air temperature < zone
temperature +10°F] (5.5°C), the control action remains
the same and the UC210 controls to the minimum flow
set point. If an auxiliary temperature sensor is not
installed and configured for supply air temperature, the
UC210 will retain the last control action in effect.
Bottom Access
An optional bottom access can be provided in the
casing of fan powered series or parallel terminal unit.
The 22-gauge door is lined with 1 inch, 26-gauge, dual
wall insulation and thermal lined with 1 inch – 1 lb.
density fiberglass insulation with a 3.85 R-value.
Each door includes 1 to 6 cam locks that are used to
secure the door to the casing.
The cam lock engages a metal encapsulated frame on
the unit that encloses the unit insulation to prevent air
erosion.
The cam lock engagements are interlocked using a flat
head screwdriver. Once unlocked, the entire door
assembly can be removed for access.

Adjusting the SCR Motor Speed
Control
In order to make units more convenient and efficient to
balance, an SCR (silicone control rectifier) is provided
as standard on all fan-powered units.
The SCR is located on the side of the fan control box.
To adjust the speed of the motor, the external knob
must be rotated either clockwise or counterclockwise
depending on the desired speed adjustment.
There is an internal potentiometer setting on the SCR
controller that can be accessed by removing the control
box cover. This internal potentiometer is set at the
factory to the specific motor voltage.
It may be necessary to adjust this in the field
depending on the building power factor.

N o t e : This feature only verifies airflow is set properly. It
does not indicate actual ECM speed. The ECM
must be load tested. The ECM must be
connected to the fan to properly test the ECM
and display fan speed.
The following tables provide mapping from fan
percent-on setting to fan airflow for each fan type and
size. Additional fan settings can be determined by
interpolating from the tables or using the following
equation:
•
Max
Airflow setting = Airflow min + {(Potentiometer
Setting) x [(Airflow max - Airflow min)/100]}

Figure 23. ECM control board – Non-modulating
control with Trane unit controller (excludes Tracer®
UC210 and UC400) or non-Trane unit controller
An alternate ECM interface (shown in Figure 24, p. 33)
is utilized on unit with Non-Trane unit controller
including factory mounted third-party unit controllers.
This ECM interface allows fan modulation and fan on/
off control from the unit controller. There are two input
signal options as well as a temporary adjustment via
manual potentiometer.
•
0-10 VDC modulation signal with separate on/off
binary signal.
•
2-10 VDC modulation signal where the ECM starts
at a rise to 2 VDC and stops at a fall to 1 VDC.
N o t e : 2-10 VDC input signal requires the shunt to be
installed on the “P” terminals as shown in Figure
25, p. 33.
Figure 25. ECM control board 2-10 VDC input signal

Trane offers an energy efficient ECM as a motor option.
The optional Tracer® UC210 and UC400 unit controllers
directly interface with the ECM to control fan airflow
and fan on/off control. Other Trane and non-Trane unit
controller options require an ECM control interface
(shown in Figure 23, p. 33) to set fan airflow while the
unit controller dictates fan on/off control via a binary
output. The manual potentiometer is used to set the
percent-on or speed. The ECM control interface
contains display, which can be used to view percent-on
setting and speed.
VAV-SVX08R-EN
The ECM control interface contains two diagnostic LED
indicators, motor RPM (speed) and Motor Speed
Request. Motor RPM indicates the motor is driven and
running when lit. Motor Speed Request, represents the
percentage of the requested motor speed being

supplied to the motor. Short and long flashes are used
to indicate values from 0 to 100 percent.
•
0% is displayed as an off LED.
•
1 – 99% are represented by a series of long flashes
followed by short flashes, whereas each long flash
adds 10% and each short flash adds 1%.

Maintenance
Periodic maintenance of the VariTrane™ product is
minimal, but necessary for efficient operation. Routine
maintenance consists of inspecting/replacing the air
filters of the fan-powered terminals.
Fan Motor Replacement
Motors
Failure to disconnect power and discharge
capacitors before servicing could result in death or
serious injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper
lockout/tagout procedures to ensure the power
cannot be inadvertently energized. For variable
frequency drives or other energy storing
components provided by Trane or others, refer to
the appropriate manufacturer’s literature for
allowable waiting periods for discharge of
capacitors. Verify with a CAT III or IV voltmeter
rated per NFPA 70E that all capacitors have
discharged.
Both the Permanent Split Capacitor( PSC) and the
Electrically Commutated Motor (ECM) require no
lubrication during its normal life of operation.
Fan Wheel
Routinely inspect the fan wheel for dirt or debris and
cleaned as necessary.
Filter
Routinely inspect and/or replace the filter on fanpowered terminals depending on the environmental
conditions of the plenum.
Filter Change Out
•
To remove the filter, turn each of the filter retaining
clips 90° (CW or CCW)
•
Remove the filter and replace with new filter of the
same frame size.
•
Return the filter clips to their retaining position by
turning them 90° (CW or CCW) back to their original
position.
WARNING
Hazardous Voltage w/Capacitors!
Figure 47.
Standard motor removal
Water Coil
•
Periodically inspect water coils and clean fins.
•
Water coils are provided with an access panel as
standard to assist with inspection and cleaning.
Standard height fan-powered series and parallel fan
motors are replaceable through the filter opening and
the standard sliding side access panel. To access the
fan motor, the fan housing must be detached by
removing the mounting bolts that hold the housing to
the fan board. Removing the entire housing allows the
fan motor, fan housing, and fan wheel to be re-aligned
on a workbench or floor and prevent any possible fan
wheel rubbing that may occur. Removing the housing
will provide access to the motor shaft set screw that
holds the fan wheel to the motor shaft.
The low height fan assembly has been designed to be
removed and replaced as a complete unit.

VAV-SVX08R-EN
Maintenance
SCR Assembly
SCR solid state relays are used to switch a single heater
stage on and off. An intelligent (Master) relay is used
for all single phase applications. For three phase
applications, a Master-Slave configuration is used to
switch two legs of three phase power to the heater
stage. The Master Relay controls one leg
independently, and provides a control signal to the
Slave Relay, which controls the second leg.
Figure 48.
Typical heat sink fin orientation
Bottom View
Every Master or Master/Slave relay combination is
mounted on a heat sink to prevent the relays from
VAV-SVX08R-EN
overheating during normal operation. The SCR
assembly must always be mounted with the heat sink
fins oriented vertically (see above) with a minimum
clearance of 0.5 inches on all sides of the heat sink for
cooling. Where additional cooling slots are provided in
the heater, the VAV unit must be mounted with a
minimum of 1 inch clearance in front of the slots.
When the 0-10 VDC control voltage is present at the
Master relay in both single and three phase
applications, an ON indicating LED light on the Master
relay will blink continually (approximately 0.5 seconds
on, 1.0 seconds off). If the load side voltage is also
present at the relay(s), the Master relay LED and the
Slave relay LED blink rate will increase as the control
signal increases. When the control signal reaches a
maximum of 10 VDC, all LEDs will be lit continuously,
indicating that the relays are full-open and
continuously conducting. If the control signal is present
in three phase applications while the load side voltage
is not, only the Master relay LED will light and the blink
rate will be constant.
If the SCR assembly does not appear to be functioning
properly, verify that all required voltages are present
and all that all wiring is properly connected. If all these
conditions are verified, and the SCR LED does not light
and/or the SCR relay does not conduct, the entire SCR
heat sink assembly should be changed out. Individual
Master or Slave relays should not be replaced.
