OPERATION OVERVIEW
The VC3xxxX Series Line Voltage Switching Transformer Relay Pack(s) operate as slave
unit(s) under the control of a single master VTR73xxA Terminal Equipment Controller.
Fan operation can be configured and wired for the following:
3 Speed configuration using 3 fan relays ( Low - Med - High )
2 Speed configuration using 2 fan relays ( Low - High )
3 Speed configuration with auto fan speed mode using 3 fan relays
( Low - Med - High - Auto )
2 Speed configuration with auto fan speed mode using 2 fan relays
( Low - High - Auto )
Single fan speed configuration.
The VTR7300 Controller can be configured for typical 2 or 4 pipe heating / cooling FCU
(Fan Coil Unit) applications.
2 or 4 pipe only operation can be configured and wired for the following:
oCooling only
oHeating only
oCooling / Heating with network or local auto changeover
If replacing an existing Line Voltage FCU Thermostat, label the wires
before removal of the thermostat.
Electronic controls are static sensitive devices. Discharge yourself
properly before manipulating and installing the Terminal Equipment
Controller.
A short circuit or wrong wiring may permanently damage the Terminal
Equipment Controller or the equipment.
All VTR7300 series controls are designed for use as operating controls
only and are not safety devices. These instruments have undergone
rigorous tests and verification prior to shipping to ensure proper and
reliable operation in the field. Whenever a control failure could lead to
personal injury and/or loss of property, it becomes the responsibility of
the user / installer / electrical system designer to incorporate safety
devices ( such as relays, flow switch, thermal protections, etc…) and/or
an alarm system to protect the entire system against such catastrophic
failures. Tampering with the devices or unintended application of the
devices will result in a void of warranty.

4 | PIR Ready VTR7300 Series-Installation Guide
2 or 4 pipe only with electric reheat can be configured and wired for the following:
oCooling only
oHeating only
oCooling / Heating with network or local auto changeover
oOn-Off electric reheat only
oCooling with On-Off or modulating VDC pulsed electric reheat
( model dependent )
oHeating with On-Off or modulating VDC pulsed electric reheat
( model dependent )
oCooling / Heating with network or local changeover with On-Off
or modulating VDC pulsed electric reheat ( model dependent )
The VC3xxxX Relay Pack supplies power to the wall VTR73xxA Terminal
Equipment Controller.
The VTR73xxA Controller controls the VC3xxxX Relay Pack(s) via a simple
communication bus.
A maximum of 10 VC3xxxX Relay Pack can be used under a single VTR73xxA
Terminal Equipment Controller.
3 wires minimum are required between the VTR73xxA Controller and the first
VR7300 Relay Pack.
The 3 wire functions are known as the following:
o1 Tx / Rx Communication
o2 Power Hot 7.0 VDC 4 Watts maximum ( required for the
VTR73xxA Controller power )
o3 Power common
Commands for fan speed and valve operation are issued from the VTR73xxA
Terminal Equipment Controller to the VC3xxxX Relay Pack(s)

CONFIGURING AND STATUS DISPLAY INSTRUCTIONS
Status display
The VTR73xxA Terminal Equipment Controller features a two-line, eight-character display.
There is a low-level backlight that is always active and can only be seen at night.
When left unattended, the Terminal Equipment Controller has an auto scrolling display
that shows the status of the system. There is an option in the configuration menu to
lockout the scrolling display and to only display the room temperature and conditional
outdoor temperature to the user. With this option enabled, no local status of mode,
occupancy and relative humidity is shown.
Each item scrolls individually with the back lighting in low level mode. Pressing any key
will cause the back light to come on to high level. When left unattended for 10 seconds
after changes are made, the display will resume automatic status display scrolling.
To activate the back light to high level, press any key on the front panel. The back light
display will return to low level when the Terminal Equipment Controller is left unattended
for 45 seconds.

parameter. When Auto Fan is set to:
AS ( Default ) = Auto Speed during occupied periods. Fan is always on during
occupied periods. Low, medium and high speeds operate on temperature offset
from setpoint.
AS AD = Auto Speed / Auto Demand during occupied periods.
oMedium and high speeds operate on temperature offset from setpoint.
oLow speed operates on demand and will shut down when no

Entering a MAC address enables an automatic routine that
automatically fetches all the required configuration properties of
the current device from another already configured device an
copies the same required configured property values.
If a value other than the default value of 255 is entered, user
will then be prompted to exit the Configuration Menu thus
leaving all other parameter configuration to be copied from the
referenced controller MAC address.
Ex.: If you are currently configuring MAC12 and the settings
matches exactly the settings of ZN MAC5, then enter 5 as the
current parameter value.
If the process is successful and all required configuration
properties have been copied, the value will revert back to

For 2 Pipe output applications, the system access is limited
if RUI 1 is configured for local changeover COS, COC/NC
or COC/NC. The current water temperature detected by the
RUI 1 then limits the system mode available for the local
configuration or network write.
For sequence 2 & 3, set PulsedHt to On to enable pulsed
electric reheat applications with VR7300B & E

Mode button menu
configuration
Default is: Menu #4
Menu displayed are dependent on model used and sequence
of operation selected
Auto Mode operation for sequences 2 and 3 is dependent on
Auto Fan parameter
0 = Low-Med-High
3Speed configuration using 3 fan relays ( L-M-H )
1 = Low-High
2Speed configuration using 2 fan relays ( L-H )
2 = Low-Med-High-Auto
3Speed configuration with Auto fan speed mode
using 3 fan relays ( L-M-H-A )
3 = Low-High-Auto
2Speed configuration with Auto fan speed mode using
2 fan relays ( L-H-A )
4 = On-Auto
Single Speed configuration. Auto is for Fan on demand / On
is On all the time
DHumiLCK
Dehumidification lockout
Default value:
On = Authorized
Conditional parameter to Humidity models
VTR735xX5x00(X)
Typically toggled via the network.
This variable enables or disables dehumidification based on
central network requirements from the BAS front end
On = Dehumidification Authorized
Off = Dehumidification Not Authorized

%RH set
Dehumidification setpoint
Default is 50 % RH
Conditional parameter to Humidity models
VTR735xX5x00(X)
Used only if dehumidification sequence is enabled:
Range is: 30-95% RH
DehuHyst
Dehumidification
Hysterisys
Default is 5 % RH
Conditional parameter to Humidity models
VTR735xX5x00(X)
Humidity control hysterisys. Used only if dehumidification
sequence is enabled:
Range is: 2 to 20% RH
DehuCool
Maximum
Dehumidification
Cooling output
Default is 100 %
Conditional parameter to Humidity models
VTR735xX5x00(X)
Maximum cooling valve position when dehumidification is
enabled. This can be used to balance smaller reheat loads
installed relative to the capacity of the cooling coil.
Range is: 20 to 100 %
St-By TM
Stand-by Timer value
Default 0.5 hours
Time delay between the moment when the PIR sensor
detected the last movement in the area and the time when the
Terminal Equipment Controller stand-by mode and setpoints
become active.
Range is: 0.5 to 24.0 hours in 0.5hr increments
Unocc TM
Unoccupied Timer value
Default 0.0 hours
Time delay between the moment when the Terminal
Equipment Controller toggles to stand-by mode and the time
when the Terminal Equipment Controller unoccupied mode
and setpoints become active.
The factory value or 0.0 hours: Setting this parameter to its
default value of 0.0 hours disables the unoccupied timer.
This prevents the Terminal Equipment Controller to drift from
stand-by mode to unoccupied mode when PIR functions are
used
Range is: 0.0 to 24.0 hours in 0.5hr increments
St-By HT
Stand-by heating
setpoint
Default value = 69 °F
The value of this parameter should reside between the
occupied and unoccupied heating setpoints and make sure
that the difference between the stand-by and occupied value
can be recovered in a timely fashion when movement is
detected in the zone.
Stand-by heating setpoint range is: 40 to 90 °F
( 4.5 to 32.0 °C )
St-By CL
Stand-by cooling
setpoint limit
Default value = 78 °F
The value of this parameter should reside between the
occupied and unoccupied cooling setpoints and make sure
that the difference between the stand-by and occupied value
can be recovered in a timely fashion when movement is
detected in the zone.
Stand-by cooling setpoint range is: 54 to 100 °F
( 12.0 to 37.5 °C )
