TEC21x6(H)-4 and TEC21x6H-4+PIR Series
N2 Networked Thermostat Controllers with Dehumidification
Capability, Fan Control, and Occupancy Sensing Capability
Description
The TEC21x6(H)-4 and TEC21x6H-4+PIR
Series Thermostat Controllers are N2
networked devices that provide control of twoor four-pipe fan coils, cabinet unit heaters, or
other equipment using on/off, floating, or
proportional 0 to 10 VDC control input, three
speeds of fan control, and dehumidification
capability. The TEC21x6H-4+PIR Series
Thermostat Controllers have occupancy
sensing capability built into the device. These
devices maximize up to 30% energy savings in
high-energy usage light commercial buildings,
such as schools and hotels, during occupied
times by using additional standby setpoints.
The technologically advanced TEC21x6(H)-4
and TEC21x6H-4+PIR Series Thermostat
Controllers feature a Building Automation
System (BAS) N2 Bus communication
capability that enables remote monitoring and
programming for efficient space temperature
control. Specific models are available to
accommodate commercial and hospitality
applications.
The TEC21x6(H)-4 and TEC21x6H-4+PIR
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, Proportional-Integral (PI) timeproportioning algorithm that virtually
eliminates temperature offset associated with
traditional, differential-based thermostat
controllers.
Refer to the TEC21x6(H)-4 and
TEC21x6H-4+PIR Series N2 Networked
Thermostat Controllers with Dehumidification
Capability, Fan Control, and Occupancy
Sensing Capability Product Bulletin
(LIT-12011601) for important product
application information.
Features
• BAS N2 communication — provides
compatibility with a proven communication
network; N2 Bus is widely accepted by
Heating, Ventilating, and Air Conditioning
(HVAC) control suppliers
• onboard occupancy sensor (Passive
Infrared [PIR] Models) — provides energy
savings without additional installation time
and cost
• password protection option — protects
against unwanted thermostat controller
tampering
• integral humidity sensing capability
(dehumidification models) — increases
occupancy comfort by providing
dehumidification
• 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
• three speeds of fan control — provide easy
FAN speed selection via the interface key,
to meet the application requirements

Dehumidification
Capability
• single/dual setpoint adjustment — enables
user setpoint options to accommodate
application
• override interface key (commercial models)
— allows easy access for temporarily
overriding the unoccupied mode
• temperature scale selector key (hospitality
models) — offers guests the ability to select
a Fahrenheit (°F) or Celsius (°C)
temperature scale display
• 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 a TEC21x6(H)-4 or TEC21x6H-4+PIR
Series Thermostat fails to operate within its
specifications, replace the unit. For a
replacement thermostat, contact the nearest
Johnson Controls® representative.
