Applications

The TEC2101-3 Thermostat is an N2 networked device
that provides control of single-stage heating/cooling
equipment. The technologically advanced TEC2101-3
Thermostat features a Building Automation System
(BAS) N2 Bus communication capability that enables
remote monitoring and programmability for efficient
space temperature control.

IMPORTANT: The TEC2101-3 Thermostat is
intended to provide an input to equipment under
normal operating conditions. Where failure or
malfunction of the thermostat could lead to personal
injury or property damage to the controlled
equipment or other property, additional precautions
must be designed into the control 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 thermostat.

Figure 5: Wiring the TEC2101-3 Thermostat

Connecting the N2 Bus

To connect the N2 Bus:

1. Set the N2 address of the TEC2101-3 Thermostat
per the engineering drawings prior to wiring the
thermostat. (See the Com addr parameter in
Table 2 to set the N2 address for the thermostat.)
Also test for N2 voltage, polarity, and isolation prior
to wiring the thermostat.

2. Observe the polarity when connecting the N2 Bus
wires to the thermostat.

3. After the N2 Bus wires are connected to the first
thermostat, continue in a daisy-chained fashion to
the next thermostat.

Note: The thermostat N2 Bus is self-terminating. The
N2 Bus wiring must be twisted-pair lines. Do not run the
N2 Bus wiring in the same conduit as line voltage
wiring (30 VAC or above) or other wiring that switches
power to highly inductive loads (such as contactors,
coils, motors, or generators).

For more N2 Bus overview information, refer to the N2
Communications Bus Technical Bulletin (LIT-636018)
and ASC and N2 Bus Networking and Troubleshooting
Technical Bulletin (LIT-6363003).

N2 Device Mapping

Define the TEC2101-3 Thermostat as a Vendor Device
(VND) when adding the thermostat to the supervisory
controller.

The Thermostat Point (T ype/Address) is the fixed-point
definition inside the thermostat. The most recent N2
command received by any of the Object T y pes listed in
Table 1 controls the thermostat.

Only one of the setpoints (either Heating SP or Cooling
SP) can be overridden at a time. Overrides t ake priority
over any local adjustment or command in the
thermostat.

If a setpoint is overridden, the thermostat adjusts the
other setpoint, if necessary, to maintain the minimum
deadband between the two setpoints. The setpoints
can be spread farther apart but can never be adjusted
closer than 2F°/1C° apart.

If a supervisory controller commands an override of an
analog or binary object, all local changes attempted
through the thermostat keypad for that object are
ignored until the override is released. For example, if
the supervisory controller sends an override message
to turn System Mode Off, and then the user selects
System Mode On at the thermostat keypad, the
thermostat keeps the System Mode Off.

When an override is released, the object may once
again be changed through the thermostat keypad, but
the thermostat does not retain any data entered at the
thermostat keypad during the override.

All overrides are released automatically after
10 minutes of no communications (for example, if the
network cable is removed from the thermost at, causing
a loss of network communications).

Metasys® System Person-Machine Interface (PMI)

Do not direct-map any points; instead, run control of
these points through the Control System (CS) object.
The supervisory controller Model Point Type is the
definition inside the model file. Use a CS object to
retrieve the data.

Metasys System Extended Archit ecture

There must not be a Relinquish Default for the
setpoints if it is desired to change them from the
thermostat display. If there is a Relinquish Default for
the setpoints, the supervisory controller always has an
Override for either an Adjusted value or the Relinquish
Default value. Use the Operator Override and the
Release Operator Override to command the setpoint
and release it to local control. At that time, the user is
able to change the setpoint from the local display.

2. The Heating and Cooling Setpoint (SP) cannot be overridden simultaneously (this also applies to the Setback Heating SP
and Setback 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 TEC2101-3 thermostat to maintain the
minimum deadband between the two setpoints.

3. The Multiple Command Output (MCO) object is used to schedule multiple Multi-State Objects (MSOs).

4. When defining the N2 MSO, select TEC Mode from the States Text Menu. Type 4 for the TEC2101-3 thermostat.

5. On the Metasys Network Control Module (NCM) system, map BD-9 Temp Units Mode as a Binary Output (BO) object with
Auto Restore and Local Control set.

6. Can be a Change-of-State (COS) alarm to the BAS or N2 Dialer Module (NDM) to initiate a dial-out.

7. 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.

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.

TEC2101-3 N2 Networked Single-Stage Thermostat Installation Instructions 5

The most recent N2 command received by any of the
N2 Bus Objects listed in Table 1 controls the
thermostat.

If an Analog Data (AD) object is overridden by the
Metasys system, all local changes attempted through
the thermostat keypad for that AD object are ignored
until the override is released. For example, if the
Metasys system sends a write command to turn
System Mode Off, and 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, and then the occup ant 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 SP or Cooling SP)
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 maint ain the minimum 2 F°
deadband between the setpoints. The setpoint s can be
spread farther 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
TEC2101-3 thermostat.

Overrides take precedence over any local adjustment
or command in the TEC2101-3 thermostat.

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).
