Open unit by pulling on the bottom
side of Terminal Equipment
Controller (fig. 1).
Remove wiring terminals from sticker.
Please read the FCC ID and IC label
installed in the cover upon removal of
cover for the wireless products.
Location
1. Should not be installed on an outside
wall.
2. Must be installed away from any
direct heat source.
3. Should not be installed near an
air discharge grill.
4. Should not be affected by direct
sun radiation.
5. Nothing should restrict vertical
air circulation to the Terminal
Equipment Controller.
Installation
1. Swing open the Terminal
Equipment Controller PCB to
the left by pressing the PCB
locking tabs (fig. 2).
2. Pull out cables 6” out from the
wall.
3. Wall surface must be flat and
clean.
4. Insert cable in the central hole
of the base.
5. Align the base and mark the
location of the two mounting
holes on the wall. Install base in
the proper orientation. Arrow on
base should be facing up.
6. Install anchors in the wall.
7. Insert screws in mounting holes
on each side of the base (fig. 2).
8. Gently swing back the circuit
board on the base and push on
it until the tabs lock it.

THEORY OF OPERATION
The VT7600 uses a Viconics proprietary adaptive logic algorithm to control the space
temperature. This algorithm controls the heating / air conditioning system to minimize
overshoot while still providing comfort. It provides exceptional accuracy due to its unique
PI time proportioning control algorithm, which virtually eliminates temperature offset
associated with traditional, differential-based on/off Terminal Equipment Controllers.
Fig.2 - On/Off mechanical control vs PI electronic control.
Features overview
7 day schedule models, 2 or 4 events
Built-in dehumidification control function with local ambient humidity sensing
Selectable single or dual compressor stages
Remote indoor averaging sensing capability
Temperature averaging with 2, 3, 4, 9 or 16 sensors
System mode lock out
When replacing an existing Terminal Equipment Controller, label the
wires before removal of the Terminal Equipment Controller.
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 VT7000 series Terminal Equipment Controllers 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 VT76xxW Series-Installation Guide
Remote discharge air temperature sensor input for monitoring purpose
Remote water temperature sensor input for monitoring purpose
Lockable keypads for tamper proofing. No need for a separate guards
Anti short cycle and minimum on/off run time protection. Reduces wear and
maximizes life span of mechanical equipment.
2 configurable digital inputs for added flexibility. Each input can be configured as the
following:
None: No function will be associated with the input
Service: a backlit flashing Service alarm will be displayed on the Terminal
Equipment Controller 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.
Filter: a backlit flashing Filter alarm will be displayed on the Terminal
Equipment Controller LCD screen when the input is energized. It can be tied to a
differential pressure switch that monitor filters
Rem NSB: remote NSB timer clock input. Will disable the internal scheduling of
the Terminal Equipment Controller. The scheduling will now be set as per the
digital input. The menu part related to scheduling is disabled and no longer
accessible. It provides low cost setback operation via occupancy sensor or from
a dry contact
RemOVR: temporary occupancy contact. Disables all override menu function of
the Terminal Equipment Controller. . 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.
With this function enabled it is now possible to toggle between unoccupied &
occupied setpoints for the amount of time set by parameter (TOccTime)
temporary occupancy time.
Fan lock: used in conjunction with a local air flow sensor connected to the input.
Locks out the Terminal Equipment Controller heating and cooling action and
displays a local alarm if no air flow is detected 10 seconds after the fan (G
terminal) is energized.
Configurable smart fan operation saves energy during night mode
Non volatile EEPROM memory prevents loss of parameters during power shortage
Built in default profile set-up for easier start up and commissioning
Configurable SPST output relay for lighting, exhaust fan or fresh air control
6 hour typical reserve time for clock in case of power loss on scheduling models

Temporary setpoints can be modified through the Up arrow key (▲) and the Down arrow
keys (▼).
User will be prompted with the present mode (Heating or Cooling) of the Terminal
Equipment Controller and its setpoint.
The Up (▲) arrow key will increment the setpoint by 0.5 degree (F or C).
The Down (▼) arrow key will decrement the setpoint by 0.5 degree (F or C).
Press the Yes key to accept the new setpoint.

*Scheduling consecutive events to the same time will cause the Terminal Equipment
Controller to choose the last event as the time at which it will set its schedule. In the above
example for Saturday, the Terminal Equipment Controller will control to the occupied set
point from 8:00 AM until 11:59 PM. Since it is desired to be in occupied mode throughout
the night, then it is necessary to schedule the first event on Sunday at 12:00 AM. The
Terminal Equipment Controller will force a one minute unoccupied period for a one minute
period (between 11:59 PM and 12:00 AM on Saturday).
