TEC2100 Series Networked Thermostats

The TEC2100 Series of thermostats is a family of
highly advanced thermostats specifically designed for
control of equipment such as rooftop units (with and
without economizers), heat pumps, and single and
multi-stage heating/cooling equipment. The TEC2100
features Metasys® system N2 Bus communication
capability that enables remote monitoring and
programmability for efficient space control. The
TEC2100 used an intuitive, plain text, menu driven
backlit display that makes setup and operation quick
and easy.

The TEC Series includes four models: Single-stage
(TEC2101-1), Heat Pump (TEC2102-1), Multi-stage
(TEC2103-1), and Economizer (TEC2104-1). All
thermostats use a unique proportional control
algorithm that virtually eliminates temperature offset
associated with traditional differential-based
thermostats.

Product Overview

The TEC2100 Series of thermostats are specifically
designed for networked control of the most common
commercial heating and cooling equipment. In addition
to superior temperature control and application
flexibility, the TEC2100 provides the advantage of the
Metasys N2 Network communication, so the user can
view operation or make adjustments at the thermostat
or from a remote workstation. For local interface, the
plain text menus, backlit display, and five interface
keys make setup and operation of the thermostat
extremely simple.

IMPORTANT: Use this TEC2100 Series
networked thermostats only as an operating control.
Where failure or malfunction of these thermostats
could lead to personal injury or property damage to
the controlled equipment or other property,
additional precautions must be designed into the
system. Incorporate and maintain other devices such
as supervisory or alarm systems or safety or limit
controls intended to warn of, or protect against,
failure or malfunction of the TEC2100 Series
thermostats.

Additional Features

The TEC2100 Series also offers many other features:

• Menu Driven Options
Eliminates the need for dipswitches, setup of all
configurable parameters are menu driven.

• Two Configurable Digital Inputs

Provides additional inputs, configurable for service
or filter alarms at the thermostat. These inputs can
also be user defined at the workstation for other
functions.

• Adjustable Heating/Cooling Deadband
Adjusts the minimum heating/cooling deadband
from 2 to 4F° (1 to 2C°).

• Remote Indoor and Outdoor Sensing

Accommodates remote indoor and outdoor
sensors. Up to three indoor sensors can be
average.

• Adjustable Anti-Short Cycling Timer

Adjusts the minimum on and off times for the
equipment from 0 to 5 minutes.

• Three Levels of Keypad Lockout

Provides three different levels of keypad lockout
that can be set up through the menu and interface
keys.

• Concealed Key to Access Configuration
Parameters

Enables access to all configurable parameters
while limiting unwanted parameter tampering once
the thermostat is set up.

• Three Light-Emitting Diodes (LEDs)

Provides fan, heating, and cooling status at a
glance.

• Adjustable Temporary Occupancy Time

Adjusts the temporary occupancy time from
0 to 12 hours.

• Frost Protection

Turns the heat on when the zone temperature
drops below 42°F (5.5°C) regardless of the
thermostat’s mode.

• Dry Bulb Economizer Function (TEC2104-1)

Provides a 0-10 VDC output for economizer
control. Economizer functions include dry bulb
changeover, minimum damper position, mixed air
temperature setpoint, and control of how
mechanical cooling interacts with economizer
function.

• Adjustable Heating/Cooling Cycles per Hour

Configurable for the number of heating and
cooling cycles in a one-hour period, balancing
temperature control and equipment cycling.

• High and Low Balance Point Adjustments
(TEC2102-1)

Enables more precise control of heat pump
operation based on outside air temperature.

• System Mode Lockout

Allows the heating and cooling modes to be locked
out based on outdoor air temperature when an
outdoor air sensor is connected.

• Non-Volatile EEPROM Memory

Prevents loss of adjusted parameters during
power failure.

• Network Addressing and Viewing

Allows network addressing through the menu
driven user interface. Additionally, for quick
viewing of the N2 address, pressing the YES and
NO keys simultaneously on the user interface
displays the N2 address of the TEC.
