TEC2103-2 Networked Multi-Stage Thermostat
Application
The TEC2103-2 thermostat is an N2 networked
thermostat that provides control of multi-stage HVAC
equipment. The TEC2103-2 thermostat provides
exceptional accuracy through the use of a unique
Proportional-Integral (PI) time proportioning algorithm.
The algorithm virtually eliminates temperature offset
associated with traditional, differential-based on/off
thermostats. The TEC2103-2 thermostat also uses an
adaptive control logic algorithm to control the space
temperature during recovery to minimize overshoot
while providing maximum comfort.
The TEC2103-2 thermostat has Metasys® N2
communication capability. This communication allows
the user to view and adjust parameters from a remote
workstation. Additionally, the menu driven backlit
display, plain text menus, and five keys on the
TEC2103-2 thermostat make operating the thermostat
easy and intuitive.
Note: In this document, Building Automation System
(BAS) is a generic term that refers to the Metasys
Network (Network Control Module [NCM] or N30
Series), and Companion (CPN) supervisory systems.
The specific system names are used when referring to
system specific applications.
Installation
Location Considerations
Locate the TEC2103-2 thermostat:
•on a partitioning interior wall, and approximately
5 ft. (1.5 m) above the floor in a location of
average temperature
•away from direct sunlight, radiant heat, outside
walls, behind doors, air discharge grills, stairwells,
or outside doors
•away from steam or water pipes, warm air stacks,
unheated/uncooled areas, or sources of electrical
interference
To install the thermostat:
1. Remove the security screw on the bottom of the
thermostat cover using a Phillips-head
screwdriver. Open the thermostat by pulling on
the bottom side of the thermostat cover
(Figure 1).
2. Unlock the Printed Circuit Board (PCB) by
carefully pressing the locking tabs to the right
(Figure 2). Open the thermostat’s PCB to the left.
3. Pull out approximately 6 in. (152 mm) of wires
from the wall and insert the cable through the
hole in the base.
4. Align the base on the wall, and using the base as
a template, mark the location of the two mounting
holes on the wall. Confirm the thermostat base is
installed with the proper side up.
5. Use the supplied anchors and screws for
mounting on drywall or plaster. Drill two 3/16 in.
(4.7 mm) holes at the marked locations and tap
nylon anchors flush to wall surface (Figure 3).
6. Position base on the wall, insert screws through
mounting base, and fasten into wall anchors. Do
not overtighten screws.
7. Swing the thermostat PCB back to the right to
close. Gently press on the PCB to secure each of
the locking tabs.
8. Pull out the screw terminal blocks using the
pull-tabs on each connector (Figure 4).
Note: The number of terminals on the terminal
blocks varies depending on the TEC model.

Connecting the N2 Bus
To connect the N2 Bus:
1. Observe the polarity when connecting the N2 Bus
wires to the TEC2103-2 thermostat.
Note:An End-of-Line (EOL) is not needed on the
N2 Bus at the TEC2103-2 thermostat. However,
one EOL is needed at the BAS (N30, Companion,
Network Control Module).
2. Continue this process for each TEC2103-2
thermostat using the daisy chain wiring method.
N2 Device Mapping
When adding the TEC2103-2 thermostat to the
Metasys system (Person-Machine Interface [PMI] and
Companion system), you must define the TEC2103-2
thermostat as a Vendor Device (VND). For the NCM,
except as noted in Table 1, Footnote c, do not direct
map any points. Run control of these points through
the Control System (CS) object. See the Setting the
N2 Address (N2 addr) section to set the address for
the thermostat.

d. The Multiple Command Output (MCO) object is used to schedule multiple Multi-State Objects (MSOs).
e. When defining the N2 MSO object, select TEC Mode from the States Text Menu. Type 4 for the TEC2103-2
thermostat.
f. The state of DI1 and DI2 is communicated over the N2 network even if the digital inputs are configured as None
through the local interface at the thermostat.
g. The Heating and Cooling SP cannot be overridden simultaneously (this also applies to the Unocc Heating SP and
Unocc Cooling SP). The overridden setpoint must be released prior to overriding the other setpoint. Additionally, if one
setpoint is overridden, the other setpoint may be automatically adjusted by the TEC2103-2 thermostat to maintain the
minimum deadband between the two setpoints.

6TEC2103-2 Networked Multi-Stage Thermostat Installation Instructions
The Controller Point Type is the fixed-point definition inside the controller. The BAS Model Point type is the definition inside
the model file. Use an NCM CS object to retrieve the data.
The most recent N2 command received by any of the N2 Bus Objects listed in Table 1 controls the thermostat.
If an AD object is overridden by the Metasys system, all local changes attempted through the thermostat keypad for that AD
object are igno
red until the override is released. For example, if the Metasys system sends a write command to turn System
Mode Off, then the occupant selects System Mode On at the TEC keypad, the TEC ends up with the System Mode On;
however, if the Metasys system sends an override command to turn System Mode Off, then the occupant selects System
Mode On at the TEC keypad, the TEC keeps the System Mode Off.
Once an override is released, the AD object may once again be changed through the thermostat keypad, but the thermostat
does not retain any data entered at the TEC keypad during the override.
Only one of the setpoints (Heating Setpoint or Cooling Setpoint) can be overridden at a time.
•The value for Heating SP (ADI-3) and Setback Heating SP (ADI-5) must stay within the limits established in the
controller by Minimum Heat SP (ADI-7 read-only) and Maximum Heat SP (ADI-8).
•The value for Cooling SP (ADI-4) and Setback Cooling SP (ADI-6) must stay within the limits established in the
controller by Minimum Cool SP (ADI-9) and Maximum Cool SP (ADI-10 read-only).
If a setpoint is overridden, the TEC, if necessary, adjusts the other setpoint to maintain the minimum 2 F° deadband
between the setpoints. The setpoints can be spread further apart but can never be adjusted closer than 2 F° apart.
Failure to stay within the limits for a command results in an N2 Negative Acknowledge (NAK) error from the TEC2103-2
thermostat.
Overrides take precedence over any local adjustment or command in the TEC2103-2.
You must not have a Relinquish Default for the setpoints if you want to change them from the thermostat display.
If there is a Relinquish Default for the setpoints, the Network Automation Engine (NAE) always has an Override for either an
Adjusted value or the Relinquish Default value. You should use Operator Override and Release Operator Override if you
want to command the setpoint and release it to local control.
Once all the NAE commands are released, the Override Status in the Hardware tab should be False. At that time, the user
should be able to change the setpoint from the local display.
All overrides are released automatically after 10 minutes of no communications (for example, network cable is removed
from the TEC causing loss of network communications).
