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.

• Remote Access

Allows the user to read and access TEC2100
parameters from an Operator Workstation or
through the N2 Dialer Module (NDM). Binary
inputs or the temperature alarm causes the NDM
to connect to the workstation upon
Change-of-State (COS).

• Heating and Cooling Stage Enable/Disable
(TEC2102-1, TEC2103-1, and TEC2104-1)

Allows operation of the second-stage heating or
cooling to be disabled, reverting the thermostat to
single-stage operation, on heat pump and
multi-stage thermostats.

Thermostat Interface Keys

The TEC2100 interface consists of five keys on the
front cover and one configuration key (see Figure 2)
that can be accessed by removing the front cover. The
functions of the keys are as follows. Use the:

• YES key to confirm a selection and move onto the
next menu item

• NO key when you do not desire a parameter
change, and to advance to the next menu item

• MENU key to access the Main User Menu or exit
the menu

• DOWN arrow key to scroll through menu
selections or adjust values

• UP arrow/SCROLL key to:

− scroll through menu selections or adjust

values

− stop the Status Display Menu from scrolling

and to manually scroll to the next parameter
on the menu. When left unattended for
45 seconds, the display resumes scrolling.

Backlit LCD

The TEC2100 uses a two-line, eight-character backlit
display. Low level backlighting is present during
normal operation and it brightens when any user
interface key is pressed. The backlight returns to the
lower level when the thermostat is left unattended for
45 seconds.

Light-Emitting Diodes (LED)s

Three LEDs are used to indicate the status of the fan,
call for heat, or call for cooling on the TEC2101-1,
TEC2103-1, and TEC2104-1. When:

• the fan is on, the FAN LED lights up

• heating is on, the HEAT LED lights up

• cooling is on, the COOL LED lights up

On the TEC2102-1, the three LEDs indicate heat
pump operation. When:

• the fan is on, the FAN LED lights up.

• the auxiliary heat is on, the AUX HEAT LED lights

up.

• the heat-pump compressor is on, the HEAT-PUMP
LED lights up.

Backlit, plain text, Liquid
Crystal Display (LCD)
display is easy to read
in any conditions.

Five keys on the TEC
make operation easy
and intuitive.
