Issued February 8, 2010

TEC21x7-4 Series

N2 Networked Thermostat Controllers with Two Outputs

Description

The TEC21x7-4 Series Thermostat
Controllers are N2 networked devices that
provide control of local hydronic reheat valves,
pressure dependent Variable Air Volume
(VAV) equipment f local hydronic reheat
valves, pressure dependent Variable Air
Volume (VAV) equipment with or without local
reheat, or other zoning equipment using an on/
off, floating, or proportional 0 to 10 VDC
control input. The technologically advanced
TEC21x7-4 Series Thermostat Controllers
feature a Building Automation System (BAS)
N2 Bus communication capability that enables
remote monitoring and programming for
efficient space temperature control.

The TEC21x7-4 Series Thermostat
Controllers feature an intuitive User Interface
(UI) with backlit display that makes setup and
operation quick and easy. The thermostat
controllers also employ a unique, Proportional­Integral (PI) time-proportioning algorithm that
virtually eliminates temperature offset
associated with traditional, differential-based
thermostat controllers.

Refer to the TEC21x7-4 Series N2 Networked

Thermostats with Two Outputs Product
Bulletin (LIT-12011602) for important product

application information.

Features

• BAS N2 open communication — provides
compatibility with a proven communication
network; N2 Bus is widely accepted by
Heating, Ventilating, and Air Conditioning
(HVAC) control suppliers

• password protection option — protects
against unwanted thermostat controller
tampering

• 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

• on/off, 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

• optional discharge air sensor — monitors
unit efficiency

Repair Information

If the TEC21x7-4 Series Thermostat fails to
operate within its specifications, replace the
unit. For a replacement thermostat, contact
the nearest Johnson Controls®
representative.
