PIR Ready VT7300 Series
24 Vac Low Voltage Fan Coil Thermostats
For Commercial and Lodging HVAC Applications
(Issue Date: June 16, 2008 – 028-0183_R3)
Product overview
The VT7300 PI thermostat family is specifically designed for fan coil control. The product
features a backlit LCD display with dedicated function menu buttons for simple operation.
Accurate temperature control is achieved due to the product’s PI proportional control
algorithm, which virtually eliminates temperature offset associated with traditional,
differential-based thermostats.
Models are available for On/Off, 3 point floating and analog 0 to 10 Vdc control and can
control up to three fan speed. Three additional inputs are also provided for monitoring and /
or various advanced functions.
All models feature configurable System and Fan button functions to meet all possible applications. They all contain
an SPST auxiliary switch that can be used to control lighting or auxiliary reheat.
The thermostats are also compatible with the new Viconics PIR cover accessories. Thermostats equipped with a
PIR cover provide advanced active occupancy logic, which will automatically switch occupancy levels from
Occupied to Stand-By and Unoccupied as required by local activity being present or not. This advanced
occupancy functionality provides advantageous energy savings during occupied hours without sacrificing occupant
comfort. All thermostats can be ordered with or without a factory installed PIR cover ( see ordering notes below ).

Programmable BI/UI inputs overview
Binary input #1 can be configured for the following
functions:
1. (None): No function will be associated with the
input
2. (Rem NSB): remote NSB timer clock input. The
scheduling will now be set as per the binary input.
It provides low cost setback operation via a dry
contact
•
Contact opened = Occupied
•
Contact closed = Unoccupied
3. (Motion NO) and (Motion NC): Advanced PIR
occupancy functions using a Normally Open (NO)
or Normally Closed (NC) remote PIR motion
sensor. Occupancy mode is now set as per applied
PIR function and configuration. Application
information and examples, are available on
document: APP-PIR-Guide-Exx. This document will
provide the installers and system designers with
detailed examples on applications, parameter
configuration information, sequence of operation,
troubleshooting and diagnostic help required for the
proper usage of the PIR accessory covers
4. (Window) EMS: Forces the system to disable any
current heating or cooling action by the thermostat.
The mode stays the same and the current setpoints
are the same Occupied setpoints. Only the outputs
are disabled. There is a Door/Window alarm
displayed on the thermostat to indicate to the local
tenant that the door/window needs to be closed for
cooling or heating to resume. Use NC contact.
•
Contact opened = System disabled with local
Window alarm
•
Contact closed = System enabled
3. (RemOVR): temporary occupancy remote override
contact. This function disables the central button
override function on the thermostat. The override
function is now controlled by a manual remote
momentarily closed contact. When configured in
this mode, the input operates in a toggle mode.
It is now possible to toggle between unoccupied &
occupied setpoints for the amount of time set by
parameter (TOccTime) temporary occupancy time.
4.
5. (Service): a backlit flashing Service alarm will be
displayed on the thermostat LCD screen when the
input is energized. It can be tied in to the AC unit
control card, which provides an alarm in case of
malfunction.
• Contact opened = No alarm
• Contact closed = Alarm displayed
Universal input #3 can be configured for the
following functions:
1. (None): No function will be associated with the
input
2. (COC/NH) Change over dry contact. Normally
Heat: Used for hot / cold water change over
switching in 2 pipe systems.
• Contact closed = Cold water present
• Contact opened = Hot water present
Only used and valid if system is setup as 2 pipes.
Parameter ( Pipe No ) set as 2 pipes.
Binary input #2 can be configured for the following
functions:
1. (None): No function will be associated with the
input
2. (Door Dry) Door contact & Motion detector:
This configuration is only functional if binary input
#1 is set to Motion NO or Motion NC or a PIR
accessory cover is used.
With this sequence enabled, the occupancy is now
dictated through those 2 inputs. Any motion
detected will set the zone to occupied status. The
zone will remain permanently in occupied mode
until the door contact switch opens momentarily.
The thermostat will then go in stand-by mode. If
more movements are detected, the occupied mode
will resume. While the door is opened, any
movements detected by the remote PIR sensor or
the PIR accessory cover will be ignored. Use a
Normally Closed contact switching device.
•
Contact opened = Door opened
•
Contact closed = Door closed
(Filter): a backlit flashing Filter alarm will be
displayed on the thermostat LCD screen when the
input is energized. It can be tied to a differential
pressure switch that monitor filters
• Contact opened = No alarm
• Contact closed = Alarm displayed
3.
(COC/NC) Change over dry contact. Normally
Cool: Used for hot / cold water or air change over
switching in 2 pipe systems.
• Contact closed = Hot water present
• Contact opened = Cold water present
Only used and valid if system is setup as 2 pipes.
Parameter ( Pipe No ) set as 2 pipes.
4.
•
(COS) Change over analog sensor: Used for hot
/ cold water or air change over switching in 2 pipe
systems.
Only used and valid if system is setup as 2 pipes.

If replacing an old thermostat, label the wires before
removal of the old thermostat.
Electronic controls are static sensitive devices.
Discharge yourself properly before manipulation and
installing the thermostat.
Short circuit or wrong wiring may permanently damage
the thermostat or the equipment.
Anti-short cycling can be set to 0 minutes for equipment
that posses their own anti cycling timer. Do not use that
value unless the equipment is equipped with such
internal timer. Failure to do so can damage the
equipment.
All VT7000 series thermostats are to be used only as
operating controls. Whenever a control failure could
lead to personal injury and/or loss of property, it
becomes the responsibility of the user to add safety
devices and/or alarm system to protect against such
catastrophic failures.

Programming and status display instructions
Status display
The thermostat features a two-line, eight-character display. There is a low level backlight level that is always active and
can only be seen at night.
When left unattended, the thermostat has an auto scrolling display that shows the actual status of the system. There is
an option in the configuration menu to lockout the scrolling display and to only present the room temperature and
conditional outdoor temperature to the user. With this option enabled, no local status is given of mode, occupancy and
relative humidity.
Each item is scrolled one by one 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 turn on the back light to high level, press any key on the front panel. The back lit display will return to low level when
the thermostat is left unattended for 45 seconds

Binary input no.1 configuration
Default value = None
Conditional parameter to Wireless models (VT730xX1000W)
This parameter / function is not currently supported by the wireless
thermostats.
(None): No function will be associated with the input
(Rem NSB): remote NSB timer clock input. The scheduling will now be set as per
the binary input. It provides low cost setback operation via a dry contact
Contact opened = Occupied
Contact closed = Unoccupied
(Motion NO) or (Motion NC): Advanced PIR occupancy functions using a
Normally Open (NO) or Normally Closed (NC) remote PIR motion sensor.
Occupancy mode is now set as per applied PIR function and configuration.
Application information and examples are available on document: APP-PIRGuide-Exx. This document will provide the installers and system designers with
detailed examples on applications, parameter configuration information,
sequence of operation, troubleshooting and diagnostic help required for the
proper usage of the PIR accessory covers
(Window) EMS: Forces the system to disable any current heating or cooling
action by the thermostat. The mode stays the same and the current setpoints are
the same Occupied setpoints. Only the outputs are disabled. There is a
Door/Window alarm displayed on the thermostat to indicate to the local tenant
that the door/window needs to be closed for cooling or heating to resume.
BI2
Binary input no.2 configuration
Default value = None
* these settings will disable the local override function on the thermostat.
(None): No function will be associated with the input
(Door Dry) Door contact & Motion detector: This configuration is only
functional if binary input #1 is set to Motion NO or Motion NC or a PIR
accessory cover is used.
With this sequence enabled, the occupancy is now dictated through those 2
inputs. Any motion detected will set the zone to occupied status. The zone will
remain permanently in occupied mode until the door contact switch opens
momentarily. The thermostat will then go in stand-by mode. If more movements
are detected, the occupied mode will resume. While the door is opened, any
movements detected by the remote PIR sensor or the PIR accessory cover will
be ignored. Use a Normally Closed contact switching device.
Contact opened = Door opened
Contact closed = Door closed
(RemOVR): temporary occupancy remote override contact. This function disables
the central button override function on the thermostat. The override function is
now controlled by a manual remote momentarily closed contact. When configured
in this mode, the input operates in a toggle mode.
It is now possible to toggle between unoccupied & occupied setpoints for the
amount of time set by parameter (TOccTime) temporary occupancy time.
(Filter): a backlit flashing Filter alarm will be displayed on the thermostat LCD
screen when the input is energized. It can be tied to a differential pressure switch
that monitor filters
