TEC26x7VVT-2 Series BACnet® MS/TP Networked Thermostats with
Two Outputs for VVT Systems
Description
The TEC26x7VVT-2 Series Thermostats are
BACnet® Master-Slave/Token-Passing
(MS/TP) networked devices that provide
control of pressure dependent Variable Air
Volume (VAV) equipment with or without local
reheat, or other zoning equipment using a
floating or proportional 0 to 10 VDC control
input for Variable Air Volume and
Temperature (VVT) systems. The
technologically advanced TEC26x7VVT-2
Series Thermostats feature a Building
Automation System (BAS) BACnet MS/TP
communication capability that enables remote
monitoring and programmability for efficient
space temperature control.
The TEC26x7VVT-2 Series Thermostats
feature an intuitive user interface with backlit
display that makes setup and operation quick
and easy. The thermostats also employ a
unique, Proportional-Integral (PI)
time-proportioning algorithm that virtually
eliminates temperature offset associated with
traditional, differential-based thermostats.
Refer to the TEC26x7VVT-2 Series BACnet
MS/TP Networked Thermostats with Two
Outputs for VVT Systems Product Bulletin
(LIT-12011227) for important product
application information.
Features
• BACnet MS/TP communication — provides
compatibility with a proven communication
network; BACnet MS/TP is widely accepted
by Heating, Ventilating, and Air
Conditioning (HVAC) control suppliers
• backlit Liquid Crystal Display (LCD) —
offers real-time control status of the
environment in easy-to-read, English plain
text messages with constant backlight that
brightens during user interaction
• floating or proportional 0 to 10 VDC control
— offers additional application flexibility by
providing more advanced control signals
• override interface key — allows easy
access for temporarily overriding the
unoccupied mode
• simplified setpoint adjustment — enables
the user to change the setpoint by simply
pressing the UP/DOWN arrow keys
• two configurable binary inputs — provide
additional inputs for advanced functions
such as remote night setback, service or
filter alarms, motion detector, and window
status
• over 20 configurable parameters — enable
the thermostat to adapt to any application,
allowing installer parameter access without
opening the thermostat cover
• discharge air sensor — monitors unit
efficiency
